In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

Answer 2

Step-by-step explanation:

Let the 2-digit number be 10x+y

Therefore according to first condition

x+y = 5 --------(1)

According to second condition

10x+y - (10y+x) = 9

10x+y - 10y-x = 9

9x+ - 9y = 9

Therefore x-y = 1 ---------(2)

Add (1) and (2)

x + y = 5

x - y = 1

--------------

2x = 6

Therefore x = 6/2

= 3 ------------(3)

3+y=5 -----------( From 1 and 3 )

y = 5-3

= 2

Therefore Original number = 10x + y

= 10(3) + 2

= 30+2

= 32
