Question

According to this equation, F=ma, how much force is needed to accelerate a 65-kg runner at 8m/s2?

A.
8 m/s

B.
520 N

C.
520 m/s

D.
8 N

Answer 1

F = ma
F = 65 kg x 8 m/s^2
F = 520 N
The correct option is (c).

Answer 2

m represents mass whereas "a" represents acceleration...simply multiply both the values
i:e 65 * 8
520N

Answer 3

correct option is not c ..lol ....look at the units it's "b"

Answer 4

Which best explains why elements with a completely full outer shell of electrons do not usually bond with other elements to form compounds?

A.
These elements have obtained electrons from other elements without bonding to create a full outer shell of electrons, and a stable state.

B.
Because electrons orbit some atoms in three dimensional space, they move to different orbitals to stabilize the atom, making the formation of compounds unnecessary.

C.
A full outer shell of electrons indicates a stable state, making the formation of compounds unnecessary. The full outer shell was obtained by releasing electrons instead of forming a compound.

D.
Elements with a completely full outer shell of electrons are in their most stable state. Therefore, achieving stability through the formation of compounds is not necessary.
