Answer:
I'm pretty Sure. Yea look.
Explanation:
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
The potential energy is defined as the energy is contained in the body due to the height over the surface of the earth and it is calculated from the equation
<em>where:</em>
- PE: the potential energy in Joules.
- m: the mass of the body in kg.
- g: the acceleration due to the gravity in m/
- h: the height of the body over the earth in meters.
<em>in our problem:</em>
Answer:
A frame of reference is the location from which motion is perceived and measured. For all observers, the speed of light remains constant.
Explanation:
Condensation<span> is the change of </span>water<span> from its gaseous form (</span>water vapor) into liquid water<span>. </span>Condensation<span> occurs in the atmosphere when warm air rises, cools and looses its capacity to hold </span>water vapor<span>. As a result, excess </span>water vapor <span>condenses to form cloud droplets.</span>
The force on the box is:
F = mgsin∅
If we multiply by this with the distance it traveled, we will know the work done by the box.
W = dmgsin∅
This work will be converted to elastic potential energy in the spring which is:
1/2 kx². Equating these and substituting values:
1/2 * 170 * x² = 4 * 13 * 9.81 * sin(30)
x = 1.73 m
The box's maximum speed will at the point right before contact with the spring, when the compression is 0.
