A child is on a pogo stick. At the top of her jump, kinetic energy (KE) = 0 J, gravitational potential energy (GPE) = 100 J, and

the potential energy in the spring (SPE) = 0 J. At which point in the jump is the kinetic energy the greatest?

Because just before the pogo stick contacts the ground the system has its greates velocity.  

2.) A  

Because they have the same mass and the same height.  

3.) D  

Because the velocity is 0 (KE is 0), The Height is 0 (GPE = 0) and the spring is compressed due to converting all the kinetic enrgy into SPE.

Which statements describe nuclear reactions? Check all that apply.
Alexandra [31]

Explanation:

Nuclear reactions are the reactions in which nucleus of an atom changes either by splitting or joining with the nucleus of another atom.

There are two types of nuclear reactions.

  • Nuclear fission - In this process, large atomic nuclei splits into smaller nuclei.  
  • Nuclear fusion - In this process, two small nuclei combine together to form a large nuclei.

Both nuclear fission and fusion processes involve nuclei of atoms.

For example, ^{0}n + ^{235}_{92}U \rightarrow ^{236}_{92}U \rightarrow ^{144}_{56}Ba + ^{89}_{36}Kr + 3n + 177 MeV

Thus, we can conclude that statements which are true are as follows.

  • Nuclear reactions involve the nuclei of atoms.  
  • The products of nuclear reactions are lighter than the reactants.
