Answer:

The correct option is;

Rachael's motion energy is being turned into other types pf energy

Explanation:

Here we have Rachael pushing off from the wall to generate motion energy. The motion energy makes Rachael glide such that she is displaced while at the same time she overcomes resistances to the motion, (rolling) of the tires  from the ground as well as generates some audible noise and heat. These are all forms of energy that takes up the initial motion energy that Rachael had.

Final answer:

In Rachel's motion example, the key true statements are that her motion energy is being converted into other forms of energy and that friction from the ground is slowing her down. Energy conservation and friction are fundamental concepts in explaining her motion.

Explanation:

Rachel is wearing roller skates and is standing next to a wall. She pushes off from the wall and then glides to a stop. Let's examine which statements about Rachel's motion are true:

Answer:

1.94 * 10^8 m/s

Explanation:

as n= c/v

so v = c/n where c is the speed of light in vacuum so

v = 3 * 10^8 / 1.54 = 1.94 * 10^8

Final answer:

The speed of light in halite, or rock salt, with an index of refraction of 1.54, is approximately 1.95 x 10⁸ meters per second, calculated using the formula for the speed of light in a material based on its index of refraction.

Explanation:

The question asked is about determining the speed of light in a mineral known as halite, or rock salt, which has an index of refraction of 1.54. The index of refraction is the ratio of the speed of light in a vacuum to the speed of light in the material. To find the speed of light in halite, we can use the formula:

Speed of Light in Mineral = Speed of Light in Vacuum / Index of Refraction

Given that the speed of light in a vacuum is approximately 3.00 x 10⁸ m/s, we can substitute the values into the equation:

Speed of Light in Halite = 3.00 x 10⁸ m/s / 1.54

This gives us a speed of approximately 1.95 x 10⁸ m/s. Therefore, the speed of light in halite, or rock salt, is around 1.95 x 10⁸ meters per second.

speed =frequency ×wavelength

1200×1.2=1440m/s

s=2d/t

1440=2d/5

2d=7200

d=3600m

The distance of the ocean at this location should be considered as the 3600 m.

Since we know that

speed =frequency ×wavelength

So,

1200×1.2=1440m/s

Also we can say that

s=2d/t

So,

1440=2d/5

2d=7200

d=3600m

hence, The distance of the ocean at this location should be considered as the 3600 m.

The image distance for an object placed 19 cm in front of a concave mirror with a focal length of 10 cm is approximately 27 cm.

The image distance for an object placed 19 cm in front of a concave spherical mirror with a focal length of 10 cm can be determined using the mirror equation: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. Plugging in the given values of f = 10 cm and do = 19 cm into the equation gives 1/10 = 1/19 + 1/di. Solving for di yields an image distance of approximately 27 cm. Therefore, the correct answer is 27 cm.

Answer:

2.835 Watts

Explanation:

P = I²R

P = 1.5² × 1.26

P = 2.835 Watts

Answer:

1. Potential energy is converted into kinetic energy since they are in motion.

2. As they slope down, work is done against the dissipative forces e.g; Air resistance, viscosity ( friction ). Hence energy is lost.

3. Different weights and heights at which they started sloping.

[tex]potential \: energy = mgh[/tex]

where mg is the weight.

h is the height moved

therefore, weight and height determines the potential energy.

When skiers descend, their potential energy converts to kinetic energy, which powers their movement. Energy is lost through friction and air resistance, reducing their overall energy. Different skiers can have different potential energy due to their varying mass.

1. As the skiers move down the mountain, their potential energy, which is energy stored due to their elevated position, is converted into kinetic energy. This is the energy of motion that allows them to accelerate and move downhill.

2. In theory, potential energy would convert perfectly to kinetic energy. However, in reality, some energy is lost due to friction between the skis and the snow and through air resistance. These forces cause the skiers to lose speed over time, which means they will not be able to reach their original height when performing tricks.

3. Even though all skiers launch from the same location, their potential energy could vary due to differences in mass. According to the formula for potential energy which is PE = mgh (mass x gravity x height), a skier with a larger mass would have more potential energy than a skier with smaller mass, assuming they are at the same height.

Answer:

last option is the correct one

Answer:

D. Each will reflect at an angle equal to its angle of incidence.

Explanation:

Answer:

These fields have electric and magnetic energy, therefore the light wave carries energy.

it does not transport matter

Explanation:

Light is an electromagnetic wave formed by the oscillation of electric and magnetic fields.

These fields have electric and magnetic energy, therefore the light wave carries energy.

But the wave does not need matter for its movement, which is why it transports matter. If we use the criterion of special relativity the mass of a light wave that travels at speed must be zero, so with this criterion it does not transport matter either

Final answer:

A light wave reflected from the Moon to Earth carries energy in the form of light and momentum, but it does not carry matter.

Explanation:

When a light wave strikes the moon and is reflected towards Earth, it carries energy but not matter. Light interacts with matter by reflecting, transmitting, or being absorbed, which may convert it into other forms of energy like heat. However, light itself is a form of energy and does not carry matter. The moon reflects sunlight, which then travels to Earth, illuminating the moon phases we observe.

Since light carries momentum as well, the energy transfer occurs when light impacts matter, but the absence of mass means no matter is carried with the light waves as they travel from the Moon to Earth.

Answer:

C my brodaz

Explanation:

Answer:

Option A. 10 degrees

Explanation:

When a charged particle is placed magnetic field, it will possess magnetic force. The force acting on the particle is given by :

[tex]F=ilB\sin\theta[/tex]

i and l are current and length of wire

Here,

[tex]\theta[/tex] is the angle between velocity and magnetic field.

The force is minimum when the value of [tex]\sin\theta[/tex] is minimum.

[tex]\sin(10)=0.17\\\\\sin(30)=0.5\\\\\sin(45)=0.707\\\\\sin(90)=1[/tex]

It is clear that the value of sin(10) is minimum out of all other angles. So, the force on a current-carrying wire is minimum when the current is moving at what angle of 10 degrees to the magnetic field

The force on a current-carrying wire is minimum when the current is at a 90-degree angle to the magnetic field because the sine of 90 degrees is zero, resulting in zero force.

The force on a current-carrying wire is minimum when the current is moving at a 90-degree angle to the magnetic field. This is because the force on a wire within a magnetic field is given by the equation F = IlB sin( heta), where F is the force, I is the current, l is the length of the wire, B is the magnetic field strength, and heta is the angle between the direction of the current and the magnetic field. Since the sine function reaches its minimum value at heta = 90 degrees or heta = 270 degrees, which corresponds to sine values of 0, the force is minimum at these angles.

Boiling point

Explanation:

A liquid turns into a vapor at a certain temperature, known as the boiling point.

The boiling point is the temperature at which a liquid transforms into a gas. It is a fundamental concept in chemistry and is typically related to phase transitions and thermodynamics. In Dalton's experiment, the boiling point of the liquid under study was observed to be 135°C.

The boiling point is the temperature at which a liquid transforms into a gas or vapor. In Dalton's investigation, the boiling point of the liquid he was studying was 135°C. This concept applies when substances are undergoing a phase transition from liquid to gas, which is a core principle of chemistry. During this process, the average kinetic energy of the molecules of the liquid increases, and more molecules have sufficient energy to escape from the liquid into the gas phase.

The observation of a substance changing states due to an increase in temperature, as Dalton has done in his experiment, is crucial to understanding the nature and properties of the substance. The transition of a substance from a liquid to a gas is also an important concept in thermodynamics, with applications in areas such as cooking and the semiconductor industry.
