A particle of mass 0.2kg is attached to one end of a string of length 80cm. The particle moves in a horizontal circle with angular velocity of 1.5rev/s with the string inclined at an angle. Find the angle.(g=10m/s²)​

see earlier

  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

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

the right answer is 0.3 meters per second
