Answer 1

Answer:

Hope it is useful for you mate!!!

Answer 2

The correct answer is option (C) kg /$m^{2}$

Explanation:

• The proper combination of force will be kg /$m^{2}$ sec (option C)
• From Newton's second law of motion, we know that force the rate of change of momentum of a body is equal to the force applied.
• When we write Newton's second law in a formula we have:
• Force = Mass x acceleration
• So, from this, we can find the proper combination of force.
• The unit of mass will be kg.
• While the unit of acceleration will be $m^{2}$/ sec
• When we will find the production of these we get the unit of force as:
• Force =  kg /$m^{2}$x  / sec
• Force =  kg /$m^{2}$/ sec
• Hence, the proper combination of force will be kg / sec.
