Answer:

<em>The Hamster in a friction less exercise can move as fast as 10m/s at a constant speed  for wheel system</em>

Explanation:

<em>If the Energetic hamster keeps running faster, with less friction for a wheel system, there would be no limit for the hamster, until it starts approaching a light speed. A torque is not applied by The hamster to the wheel to move it, because the torque its self is a force, the torque is not a force that is stored up, it’s the angular velocity that is stored  </em>

<em> The relationship between a linear velocity and angular velocity is stated below </em>

<em>V= r w </em>

<em>If the hamster can move its leg in a fast way he can get to 10 m/s for a wheel system, finally, the hamster do nothing more than to so in the wheel at a speed that is constant. </em>

<em>Furthermore, the initial torque that is provided by the hamster deceases, then when the speed increases, the hamster will move faster as it can.  </em>

dlinn [17]
The average kinetic energy of a gas particle is directly proportional to thetemperature. An increase intemperature increases the speed in which the gas molecules move. Allgases at a given temperature have the same average kinetic energy. Lightergas molecules move faster than heavier molecules.

andrew-mc [135]

Dr. Arenas is a scientist who has been trying to determine if increasing pressure will increase the sound that occurs when two chemicals explode. She measures the volume of the sound that occurs at the minimum pressure at which the explosion will occur. She then increases the pressure and measures the volume of the explosions that occur. What kind of investigation is the scientist conducting?

A vector represents motion because it shows <br> and
Semenov [28]

Answer:

Vectors are used in science to describe anything that has both a direction and a magnitude. The ball's velocity vector describes its movement—the direction of the vector arrow marks the ball's direction of motion, and the length of the vector represents the speed of the ball.

The electromagnetic wave that delivers a cellular phone callto
spin [16.1K]

Answer:

E=2.41\cdot 10^{-5} J

Explanation:

The intensity of an electromagnetic wave can be expressed in terms of the magnetic field using the next relationship:

I_{average}=\frac{cB_{0}^{2}}{2\mu_{0}} (1)

  • c is the speed of light (3*10⁸ m/s)
  • μ₀ is the permeability of free space (in vacuum ) (1.26*10⁻⁶ N/A²)
  • B₀ is the magnetic field

I_{average}=\frac{3\cdot 10^{8}(1.5\cdot 10^{-10})^{2}}{2\cdot 1.26\cdot 10^{-6}}

I_{average}=2.68\cdot 10^{-6} W/m^{2}

Now, let's define the relationship between power (P) and average intensity (I).

I_{average}=\frac{P}{A}

  • P is the power
  • A is the area crossed

So we can calculate the power.

P=I_{average}\cdot A=2.68\cdot 10^{-6}\cdot 0.20=5.37\cdot 10^{-7} W

Finally, energy is the product of P times time, so:

E=P\cdot t=5.37\cdot 10^{-7} \cdot 45=2.41\cdot 10^{-5} J

I hope it helps you!
