An object is oscillating as depicted in the expression below. What is the period T ? Assume that the units work out and the amplitude is in millimeters and the time t t is in units of seconds. x ( t ) = sin ( π 10 t )

A. 110s
B. π5s
C. π10s
D. 10s
E. 20s

The time period of the object is 0.2 seconds.

Explanation:

An object is oscillating as depicted in the expression below :

........(1)

The general equation is given by :

 .......(2)

Comparing equation (1) and (2) we get :

The relation between angular frequency and time period is given by :

T = 0.2 seconds

So, the time period of the object is 0.2 seconds.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
