What is nuclear energy

Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atom's dense nucleus. Nuclear energy is seen when nuclear fusions or fissions happen.

How much work will it take to lift a 4-kg baby 1 meter into her crib

39.2j

Is it bad if you have a heavy period on one month and a light one the next month

No it is not bad, as some ladies have a heavy period for one month and then a light one or they may have two heavy periods and then one light one also.

In an isolated system, two cars, each with a mass of 1,000 kg, collide Car 1 is initially at rest, while Car 2 was moving at 10 m/s What is the magnitude of their combined momentum after the collisi

10,000 kg-m/s

What is an example of conditions not producing work

the momentum must be greater than the force . the force may be very large

How much work must be done on a 5 kg snowboard to increase its speed from 2 ms to 4 ms

work=mass*speed,5*2=10

Which can be described as in an isolated system momentum is always conserved

Law of conservation of momentum.

How does the density of a liquid compare with the density of a solid

That depends on the liquid and the solid. Liquid mercury has a very high density. Liquid gasoline has a very low density. At the melting point the density of a liquid and a solid are almost the same.

Is it true that energy is the force that causes an objects displacement

false
