Explanation:
The tyre is a hoop of steel that is fitted around the steel wheel centre and a groove on inside diameter of a flange face. The diameter inside is machined to be slightly less than the wheel diameter at the centre on which it is mounted to give an interference fit.
This is a question about converting energy from one form to another.
<span>While it is sitting on the ledge, it isn't moving, so at that point it doesn't have any kinetic energy. What it has is gravitational potential energy due to its height above the ground. </span>
<span>Just as it lands, it's at ground level, so it doesn't have any gravitational potential energy anymore. </span>
<span>The reason is that on the way down, it sped up, so all its original gravitational potential energy was turned into kinetic energy. </span>
<span>So if you can work out how much potential energy it had to start with, you will know that that is how much kinetic energy it ended up with just before it landed. </span>
<span>potential energy = m * g * h </span>
<span>where m is the mass, g is the acceleration due to gravity and h is the height </span>
potential energy = 4.45 * 9.81 * 0.800 = 35.3 J
Hope that helps. Please give me Brainlyest answer. :]
Explanation:
It is known that formula for energy per unit area per unit time is as follows.
S = 
= 
E = 
Now, putting the values we will calculate the electric field as follows.
E =
= 
= 1341.03 V/m
Now, we will calculate the average magnetic field as follows.
B = 
= 
= 
T
= 
Thus, we can conclude that the average (rms) value of the magnetic field is .
<span>When water changes to steam , you are heating the substance, hence it is absorbing (heat) energy. So 'B' is a reasonable answer. </span>
They transfer energy. Not sure what your choices are but this is a common question
