A 4 kg rock is rolling 10 m/s find its kinetic energy
larisa [96]
The answer is 200 J

The kinetic energy (KE) is:
KE = 1/2 m * v²
m - mass of the object
v - velocity of the object

We have:
m = 4 kg
v = 10 m/s

KE = 1/2 * 4 kg * 10² m/s
KE = 200 J

What happens to valence electrons when a covalent bond forms?
abruzzese [7]

Explanation:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability
