An object with a mass of 5.0 kg accelarates 8.0 m/s^2 when an unknown force is applied to it. what is the amount of force?

Force =  mass * acceleration

        = 5 * 8

Force = 40 N

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
