When applied physical force exceeds the tensile strength of the tissue to which the force is applied?

Answer:

Caffeine and stress can both elevate cortisol levels. High amounts of caffeine can lead to the negative health effects associated with prolonged elevated levels of cortisol. However, small to moderate amounts of caffeine can lift your mood and give you a boost. Caffeine can raise your heart rate and cause  extra heartbeats. And using large amounts of it for long periods can increase your risk of having a heart attack.

In the design of a thermos lab, the container that is used for comparison purposes with the thermos is typically an uninsulated container or a regular open container. This is done to demonstrate the effectiveness of the insulation in the thermos and highlight its ability to retain heat or cold compared to a container without insulation.

Purpose of uninsulated container

By checking the temperature of the thermos and the uninsulated container, you can see how heat moves differently between them. The thermos keeps drinks hot or cold for a long time because it doesn't let heat get in or out easily. But a regular container lets heat in and out more easily.

This comparison shows how well the thermos can keep drinks hot or cold for a long time. It says it's important to use insulation to stop heat from escaping, and it shows how using a thermos can keep things at the right temperature for longer.

Since the bird is initially going up, therefore upon falling form its mouth, the carrion was also going up at similar velocity of 12.8 m/s before it falls down. So calculate the distance taken during this time of momentarily going up:

(v = final velocity at the peak before it falls = 0, v0 = initial velocity = 12.8 m/s, g = gravity = 9.81 m/s^2, d is height taken)

v^2 = v0^2 - 2 g d

0 = 12.8^2 - 2 * 9.81 * d

d = 8.35 m

SO total distance it fell is:

d* = 8.35 m + 32.1 m = 40.45 m

So calculating for final velocity v (v0 = 0 since it stops at the peak before falling down):

v^2 = v0^2 + 2 g d

v^2 = 0 + 2 * 9.81 * (32.1 + 8.35)

v^2 = 793.642

v = 28.17 m/s = 28.2 m/s

You can use the weights of filled cell models to determine the rate and direction of diffusion by following these steps: weigh an empty cell model, fill the cell and weigh it again, calculate the difference in weight, divide the mass by time to calculate rate, and determine the direction based on weight change.

In order to determine the rate and direction of diffusion using weights of the filled cell models, you can follow these steps:

This method allows you to determine both the rate and direction of diffusion based on the change in weight of the filled cell models.

Actually in this case heat energy is being transferred. Heat energy or thermal energy is transferred from the burning of wood to the sausages for it to be cooked. The sausage is being heated by the fire and is absorbing the heat or thermal energy.

Atwood's machine, a physics concept, is used in real world applications like the early design of elevators, analyzing parachute descent in aerodynamics, and in designing weight-based fitness equipment.

An Atwood's machine is a device used in physics to demonstrate the principle of motion. The machine consists of two objects of different masses connected by a light, inextensible cord over a frictionless pulley.

A real world application of the Atwood's machine is found in elevators. In the early design of elevators, the car was one mass and a counterweight acted as the second mass. The counterweight ensured that the elevator car could be lifted smoothly and with minimal force, embodying the motion principle demonstrated by the Atwood's machine.

The Atwood's machine can also be applied in the field of aerodynamics. A parachute carrying a load can be modeled as an Atwood's machine, helping to calculate the rate of descent.

Furthermore, in physical therapy and fitness centers, the machine's principles apply to weight-based gym equipment. Different weights on either side of the cable help determine the force required to lift them.

A correct example of the principle of conservation of momentum is the bouncing of a basketball off the board. Therefore, option D is correct.

As momentum depends on both velocity and the direction of the body's motion, it is quantified by "mass velocity". Since velocity is a vector and mass is a scalar, momentum is a vector quantity. Mass times speed equals momentum.

"The motion of an item equal to the product of its mass and its velocity" is referred to as momentum. When something is said to have momentum, it refers to its unique mass and direction of motion.

Here, we offer a few more ideas that will help us describe motion in the future. Before Newton, the French scientist and philosopher Descartes introduced the first of them, called momentum.

Thus, option D is correct.

The Answer in significant figures is 3.20 meters. The full Answer is 3.201707577*10^0 meters

Explanation:

You must first convert 93.7Mhz to hz: 93.7mhz * 10^6hz/1Mhz = 9.37*10^7.

Next, since all EM waves' frequency and wavelength = the speed of light(c)(3.00*10^8m/s), insert the new frequency (hertz) into the formula below and solve for Wavelength (lambda)

c=(lambda)(hertz), manipulate the equation to solve for wavelength (lambda)

(lambda)=(C) / (hertz) ; Hertz = hz = s^-1 or 1/s

lambda = 3.00*10^8m/s / 9.37*10^7hz (^^remember hz = 1/s)

Since hz = 1/s, both of the factors have 1/s in the variables' place, so the 1/s cancels and your left with m (meters)

= 3.201707577 meters

Answer:

45 degrees

Explanation:

The most likely final temperature of the mixture is 45 °C

The increment in temperature adds up the thermal energy into the object. This energy is Heat energy.

Given added 50mL of water at 10°C to 50 mL of water at 80°C.

Heat lost or gained is given by Q =m Cv ΔT

Heat lost = heat gain

50 x 4.18 x (T -10)= 50 x 4.18 x (80 - T)

T-10 = 80 - T

2T = 90

T = 45°C

Thus, final temperature of the mixture is 45 °C.

If you push down on a piston in a fluid, then the pressure increases uniformly throughout the fluid. Hence, option D is correct.

A piston is a part of a variety of comparable mechanisms, including reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders, and pneumatic cylinders. It is the moving part, housed by a cylinder, and is sealed off from the atmosphere by piston rings.

The function of a piston rod and/or connecting rod in an engine is to transmit force from the expanding gas in the cylinder to the crankshaft. In a pump, the process is switched around so that force is transferred from the crankshaft to the piston in order to compress or eject the fluid in the cylinder. The piston can cover and reveal openings in the cylinder to function as a valve in some engines.

If the thalamus is damaged of a person, then they can only form visual memories but not verbal memories.

Further Explanation:

The structure of a thalamus is a midline symmetrical of two halves. It is present in the brain of a vertebrate. They are present in between the cerebral cortex and midbrain. The thalamus is a part of diencephalon which in turn is a part of the forebrain. The main functions of a thalamus are:

The inputs from the receptors are received by the nuclei present in the thalamus. The sensory information is processed by it and then the information is transfer to the cerebral cortex. In this way, it acts as a gateway for the sensory impulses it receives from the various receptors. Thus, if a thalamus of an individual is damaged, then they can only make visual memories. They cannot make verbal memories.

Answer:

the particles are moving faster

Explanation:

As we know that diffusion means the rate of escape of gas from small opening.

So here the diffusion rate is basically related to the speed of gas molecules to escape out of the closed container.

So here rate of diffusion is given as

[tex]Rate = \sqrt{\frac{P}{\rho}}[/tex]

so it depends on pressure of gas and density of gas.

Also we know that gas molecules are loosely bounded to each other as we compare the bonding between molecules of liquid.

So here we will say that correct answer is
