2. Determine the units of the quantity described by each of the following
combinations of units:
a. kg (m/s) (1/s) b. (kg/s) (m/s)
c. (kg/s) (m/s) d. (kg/s) (m/s)

Sagot :

Explanation:

a.) kg(m/s)(1/s) = force (N)

b.) (kg/s)(m/s) = force (N)

c.) (kg/s)(m/s) = force (N)

d.) (kg/s)(m/s) = force (N)

The units of the quantity described by each of the following

combinations of units are the Newton

Force is defined as the product of mass and acceleration of the body. The unit of force is Newton or kgm/s². Mathematically,

Force = mass* acceleration

Unit of mass = kg

Unit of acceleration = m/s²

Unit of Force = kg * m/s²

Unit of force is therefore also expressed as kgm/s²

According to the option given:

kg (m/s) (1/s) = kgm/s² (Thisis also equivalent to Newton)

We can also see that the other option when multiplied together will give kgm/s² which is also expressed in Newton (N)
