Answer:
potential energy = (mass × height × acceleration due to gravity.)
750 = mass × 3 × 10
hence, mass = 750/30 = 25 kg.
Answer:
A
Explanation:
Kinetic energy is the energy of an object that is moving, so D is immediately out as it is potential energy. A baseball flying at 90 mph has the greatest amount of kinetic energy because it has a higher speed.
At the time of quark confinement, when the universe was 10-6 seconds old, there is found to be one additional proton for every billion antiprotons.
<h3>What is quark confinement?</h3>
Note that one quark is never found on its own but if particles are said to be smashed together and quarks are found, they are said to be like ends of rubber bands that expands.
Hence, At the time of quark confinement, when the universe was 10-6 seconds old, there is found to be one additional proton for every billion antiprotons.

Answer:
Explanation:
Given data:
if two charge are opposite in charge then force will be attractive between then or vice versa
if one charge is positive then other charge will be negative
