Why can't you you use a pump to lift water to the third floor?

Answers

Answer 1
As the pump removes air from the well, the pressure outside the well has a greater effect because the well has less air molecules pushing back. The pressure being forced down onto the water that pushes it up the pipe would not be enough to raise the water up the pipe that high.
Answer 2

Because there are fewer air molecules pushing back as the pump removes air from the well, the pressure outside the well has a greater impact. The amount of water that could be pushed up the pipe by the pressure being applied to it would be insufficient.

What is pump?

A mechanical device called a pump is used to move various fluids from one place to another. It is a hydraulic device that transfers fluids from low to high pressure and from low to high levels of elevation.

The pump moves fluid by transforming the mechanical energy of the fluid into pressure energy (hydraulic energy).

Processes requiring high hydraulic pressure can also use the hydraulic pump. With the aid of large machinery, it may be seen. In general, heavy machinery requires high discharge pressures and low suction pressures.

Therefore,Because there are fewer air molecules pushing back as the pump removes air from the well, the pressure outside the well has a greater impact. The amount of water that could be pushed up the pipe by the pressure being applied to it would be insufficient.

What change in pressure occurs in a party balloon that is squeezed to one-half its volume with no change in temperature?

Answers

Final answer:

When a party balloon is squeezed to half of its initial volume with no change in temperature, the pressure inside the balloon doubles due to Boyle's Law, which states that pressure is inversely proportional to volume for an ideal gas.

Explanation:

The question pertains to the relationship between volume and pressure of a gas when the temperature is held constant. According to Boyle's Law, the pressure of a gas is inversely proportional to its volume when temperature remains unchanged. If a party balloon is squeezed to one-half its original volume with no change in temperature, the pressure inside the balloon will double.

For example, if the initial pressure inside the balloon (P1) was 1.00 atmosphere and the balloon was squeezed to half of its initial volume (V2 = 0.5V1), the new pressure (P2) would be 2.00 atmospheres, assuming the temperature remains steady and there are no leaks. This concept is a fundamental principle in the study of ideal gases.

Difference between contrition and compunction

Answers

Compunction is similar to an obligation; if you are "under compunction," then you are bound by some debt or sentence to do something. Repentance is actually an action rather than a feeling or condition: it is an act of the will which disowns whatever behavior you regret, and to repent implies a determination not to make the same mistake again. Contrition is the expressed emotion of being sorry for something; if you went to a person you had wronged, to make amends and ask their forgiveness, you would be "contrite" toward them. Remorse is simply another word for regret - you feel bad within yourself, either for what you did or for how the consequences affected you.

Contrition refers to sincere remorse for sins out of love for God, essential for forgiveness, while compunction is a sense of guilt or regret that may not be rooted in religious belief. The distinction between contrition and less perfect sorrow (attrition) has significant implications in the context of penance and making amends.

The concepts of contrition and compunction are often discussed in religious contexts, particularly within the Christian tradition involving the practice of penance and reconciliation. Contrition refers to heartfelt remorse for sins committed out of a love for God and a desire to change one's life. It has traditionally been seen as a deep and sincere form of penitence necessary for forgiveness in the eyes of God. In contrast, compunction is a feeling of unease or anxiety caused by guilt or regret for doing wrong or harming others, which may not necessarily be motivated by love for God but could arise out of fear of punishment or a desire to avoid negative consequences.

Throughout the Middle Ages, theologians made a distinction between contrition and a less perfect form of sorrow known as attrition, which could be transformed into contrition through the sacrament of penance. Moreover, a willingness to make amends is closely tied to feelings of remorse and sympathy, and is essential for a genuine apology or act of penance, indicating a person's desire to right their wrongs and align themselves with moral and divine expectations.

You raise a bucket of water from the bottom of a deep well. if your power output is 100 w, and the mass of the bucket and the water in it is 3.50 kg, with what speed can you raise the bucket? ignore the weight of the rope.

Answers

The approximate speed at which the bucket can be raised is 2.91 m/s.

To calculate the speed at which you can raise the bucket, we need to use the equation for power:

Power = Force x Velocity

In this case, the power output is 100 W and the mass of the bucket and water is 3.50 kg. Since the weight of the rope is ignored, we only consider the force required to lift the bucket. The force can be calculated using the equation:

Force = mass x acceleration due to gravity

Substituting the values, we have:

Force = 3.50 kg x 9.8 m/s^2 = 34.3 N

Now, we can rearrange the equation for power to solve for velocity:

Velocity = Power / Force

Substituting the values, we have:

Velocity = 100 W / 34.3 N = 2.91 m/s

Therefore, you can raise the bucket at a speed of approximately 2.91 m/s.

A heavy crate applies of 1500 N on a 25-m^2 piston . The smaller piston is 1/30 the size of the larger one . what force is needed to lif the crate

Answers

Answer:

The force needed to lift the crate is 50 N

Explanation:

[tex]P_{1} = \frac{F_{1}}{A_{1}} = \frac{1500N}{25 m^{2} } \\P_{1}= P_{2} \\P_{2} = \frac{F_{2}}{A_{2}}\\A_{2} = 25*\frac{1}{30} \\\frac{1500N}{25 m^{2} } =\frac{F_{2} }{\frac{25}{30}m^{2}  }\\ F_{2}* 25 m^{2} = 1500 N *\frac{25}{30}m^{2}\\ F_{2}= \frac{1250 N*m^{2}}{25 m^{2}}\\ F_{2}= 50 N[/tex]

Final answer:

To calculate the force needed to lift the crate, we can use Pascal's principle. The force needed to lift the crate is 50 N.

Explanation:

To calculate the force needed to lift the crate, we can use Pascal's principle. According to Pascal's principle, the pressure exerted on a fluid in a closed container is transmitted equally in all directions. In this case, the force applied by the heavy crate on the larger piston is 1500 N, and the smaller piston is 1/30 the size of the larger one. Therefore, the force needed to lift the crate can be calculated using the equation:

(Force on larger piston) / (Area of larger piston) = (Force needed to lift crate) / (Area of smaller piston)

Let's substitute the given values into the equation:

(1500 N) / (25 m^2) = (Force needed to lift crate) / (1/30 * 25 m^2)

Simplifying the equation, we find that the force needed to lift the crate is 50 N.

A 5.00X10^5 kg rocket is accelerating straight up. Its engines produce 1.250X10^7 N of thrust, and air resistance is 4.50X10^6 N. What is the rockets acceleration?

Answers

Final answer:

To determine the rocket's acceleration, subtract the air resistance from the thrust and divide by the mass of the rocket.

Explanation:

To determine the rocket's acceleration, we need to calculate the net force acting on the rocket by subtracting the air resistance from the thrust.

The net force is equal to the mass of the rocket multiplied by its acceleration. Rearranging the equation, we can solve for acceleration: acceleration = (net force) / (mass). In this case, the net force is given as the thrust minus the air resistance, so the acceleration would be (1.250X10^7 N - 4.50X10^6 N) / (5.00X10^5 kg).

Answers

The box travels a distance of approximately 3.51 meters along the incline before coming to rest.

An angle of 14.0° with respect to the horizontal is made when box slides up an incline. 0.180 is the coefficient of kinetic friction between the box and the surface of the incline. It is given that 2.20 m/s is the initial speed of the box at the bottom of the incline. The box travels a distance of approximately 3.51 meters along the incline before coming to rest.

To find this, we use the equations of motion, taking into account the forces acting on the box, including gravity, normal force, friction force, and the component of gravity parallel to the incline. By applying these equations and considering the work done by friction, we can determine the distance traveled by the box.

Water has a density that is 13.6 times less than that of mercury. how high would a column of water need to be to measure a pressure of 1 atm?

Answers

The density of mercury is 13560 kg/m³.
Therefore the density of water is about 1000 kg/m³.
1 atm pressure is 101325 Pa.
g = 9.8 m/s²

The height of a water column, h, needed to measure 1 atm is given by
(1000 kg/m³)*(9.8 m/s²)*(h m) = 101325 Pa
h = 1013225/9800 = 10.3393 m = 1033.93 cm

Answer: 10.339 m or  1033.9 cm

Final answer:

A column of mercury would need to be 73.5 cm high to measure a pressure of 1 atm.

Explanation:

The question asks for the height of a column of water needed to measure a pressure of 1 atm. We can use the information given to compare the density of water and mercury. Since water has a density that is 13.6 times less than that of mercury, a column of mercury only needs to be 13.6 times shorter than a column of water to measure the same pressure. It is stated that a column of water over 10 meters high can measure atmospheric pressure, so a column of mercury would only need to be 10 meters / 13.6 = 0.735 meters (or 73.5 cm) high to measure the same pressure.

A.) are vertical
B.) make a small angle to the vertical
C.) make a large angle to the vertical
D.) are in any position, as they each share half the weight

Answers

Assuming that the angle is the same for both ropes, then D. is the answer.  You have to consider also if the ropes are close together or far apart and if the force to move the object is in line with the ropes or perpendicular to them.
Final answer:

The tension in ropes supporting a weight is greatest when the ropes make a large angle to the vertical. The tension increases as the angle increases from the vertical, as the tension required to maintain equilibrium and support the weight increases.

Explanation:

The tension in a rope supporting a weight is greatest when the ropes make a large angle to the vertical (option C). This is due to the nature of the equation for tension, which involves both the weight being supported and the angle at which the rope(s) are positioned. As the angle increases, the vertical component of the tension decreases, which means the tension in the rope must increase to maintain equilibrium. Let's look at an example: if a 10kg weight is being supported by two ropes, each at an angle of 60 degrees to the vertical, the tension in each rope will be greater than if the ropes were vertical (0 degrees) as the vertical component of the tension needs to equal the weight to remain in equilibrium.

The wavelength of some green light is 530.0 nm. what is the frequency of this green light?

Answers

Frequency is calculated by dividing the speed of light by the wavelength. Using the normal constant of 3x10^8 m/s divided by 530 nm you can calculate it. You need to convert nm to m so it is 5.3x10^-7. Divide the constant of light by that and you get 5.66 x10^14 hz, where hz is the function 1/s.

Answer:

The answer to this question is 5.66 x (10^14) Hz

Explanation: Recall that the frequency of a light wave is the speed of light divided by the wavelength in meters.

You are given the wavelength of the light in nanometers, but the denominator of the formula is in meters. In this case, multiply 530.0 nm by 10^-9 m, resulting 5.3 * (10^-7) m.

After the conversion, divide the speed of light which is 3.0 x (10^8) m/s by the wavelength in meters. The final answer should be 5.66 x (10^14) Hz.
