Answer:
Explanation:
Given:
- mass of the honey drop 1,
- velocity of the honey drop 1,
- mass of the honey drop 2,
- velocity of the honey drop 2,
- mass of the honey drop 3,
- velocity of the honey drop 3,
<em>In ISS there is zero gravity an the collision is completely inelastic.</em>
<u>So, applying the law of conservation of momentum:</u>
Answer:
Focal length, f = 0.43 meters
Explanation:
It is given that,
Power of the reading glasses, P = 2.3 D
We need to calculate the focal length of the reading glasses. The relationship between the power and the focal length inverse i.e.
f = 0.43 m
So, the focal length of the reading glasses found on the rack in a drugstore is 0.43 meters.
Answer:
D. The direction of the force will change and it will point to regions of lower potential energy.
Explanation:
Direction will change because now you will have the opposite charge. It will still move to the lower potential because of the law of conservation of energy.
Answer:
This is a category of physics dealing with the observable phenomena, and experimental aspects by investigation, and scientific testing to measure the properties of matter, and energy.
