<span>So we want to know why the does a bouncing ball rise to a lower height with each bounce. So lets say the ball is first on some height h. There it has potential energy Ep=m*g*h. Then as the ball starts falling to the ground the energy converts to kinetic energy Ek=(1/2)*m*v^2. When the ball falls to the ground, the kinetic energy transforms to elastic energy because the ball deforms as it hits the ground and some small quantity of heat. The heat goes to the air and to the ground so it gets removed from the system. So there is less energy in the system to be converted back to kinetic energy as the ball starts to rise in height again. Thats why the ball is not able to get bact to the same height as it started from. </span>
Answer:
The spotted owl is an example of an indicator species, or an organism that shows the overall health of an environment. This could be an animal, like the owl, a bacterium, a plant, a fish, well you get the idea.
Answer:
trachea
Explanation:
The trachea is one part of the respiratory tree that is a conduit for air to pass through on its way to or from the alveoli of the lungs. This transmits oxygen to the body and removes carbon dioxide.
Answer:
The voltage drop through which the proton moves is 39.1 V.
Explanation:
Given that,
Distance = 4.76 cm
Time 
We need to calculate the acceleration
Using equation of motion
Where, s = distance
a = acceleration
t = time
Put the value in the equation
We need to calculate the voltage drop
Using formula of electric field
....(I)
Using newton's second law
....(II)
Put the value of F in equation (I) from equation (II)
Where, q = charge
a = acceleration
d = distance
m= mass of proton
Put the value into the formula
Hence, The voltage drop through which the proton moves is 39.1 V.
