5) 10
6) is correct-9
Your other answers are correct as well just when answering the second to last problem you look just the atomic number which is how many protons there is in that element. It has nothing to do with its atomic mass which is what you wrote down

Which of the following statements is/are true?Check all that apply.a. A dissipative interaction permits a two-way conversion bet

oee [108]

Answer:

a. A dissipative interaction permits a two-way conversion between kinetic and potential energies.

FALSE

in dissipative type of forces energy is not conserved so it is not possible

b. A nondissipative interaction permits a two-way conversion between kinetic and potential energies.

TRUE

in non dissipative type of force there is no energy loss so we can use energy conservation

c. A potential energy function can be specified for a dissipative interaction.

FALSE

Here potential energy is not defined for dissipative type of forces

d. A potential energy function can be specified for a nondissipative interaction.

TRUE

negative gradient of potential energy is equal to non dissipative type of forces

$F = -\frac{dU}{dr}$
