Multiply 2 cm by 100 to convert to meters

1m= 100cm

?= 2cm let ? be (n)

cross multiply

100n = 2

n= 2÷100

n= 0.02m

therefore 2cm is equal to 0.02 m

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
