A dog has a mass of 12 kg. What is its weight? Round your answer to the nearest whole number.

The dog weighs_ N.

The weight of a dog is 120N.

Explanation:

Converting kg to N, you have to multiply it by 10:

1 kg = 10 N

12 kg = 12 * 10 N

= 120N

Or you could use the formula of force, F = m*g where g is the gravity of Earth. You can use this formula because both Weight and Force have the same symbol, Newton:

m = 12 kg

g = 10 m/s²

F = 12 * 10

= 120 N

w = mg

m = 12kg, g = 9.8m/s2

w = 12kg*9.8m/s2

w = 117.6N ~ = 118N
