For a given cylindrical motor , the acting force F = 50 N . The moment of inertia j = 1/8 rad/sec 2 .The angular acceleration will be :

Select one:
a. 100 rad / s2
b. 10 rad / s 2
c. 50 rad /s 2
d. 150 rad / s 2

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

3.2x10^7

  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
