What is Dimensional Formula of Centripetal acceleration ?

Centripetal acceleration is the acceleration directed towards the centre of curvature of the path of a body which is moving along that path with a constant speed.

Mathematically,
Centripetal acceleration = (Velocity)2 / radius.

Dimensional Formula of Velocity = M0L1T-1
Dimensional Formula of Radius = M0L1T0

Putting these values in above equation we get,
Dimensional Formula of Centripetal acceleration = M0L1T-2
SI unit of Centripetal acceleration is ms-2

What is Dimensional Formula of Angular impulse ?

Angular impulse is defined as the product of  torque and time for which it acts.

Mathematically,
Angular impulse = Torque X Time.

Dimensional Formula of Torque = M1L2T-2
Dimensional Formula of Time = M0L0T1

Putting these values in the given equation we get,

Dimensional Formula of Angular impulse = M1L2T-1
SI Unit of Angular impulse is Kg m2s-1

What is Dimensional Formula of Efficiency ?

Efficiency can be  defined as the  ratio of useful output energy to the amount of input energy.

Mathematically,

Efficiency = Useful output energy / Input energy.

Dimensional formula of output energy = M1L2T-2
Dimensional formula of input energy = M1L2T-2

Putting these values in above equation we get,

Dimensional formula of Efficiency = M0L0T0.
Efficiency has no SI Unit. (As both values are of energy).

What is Dimensional Formula of Hubble constant ?

Hubble constant can be defined as the ratio of receding velocity of  an extra galactic object to the distance of that object.

Mathematically,

Hubble constant(Ho) = Receding velocity(v)/distance(d) .

Dimensional Formula of Receding velocity = M0L1T-1
Dimensional Formula of Distance = M0L1T0

Putting these values in the given equation we get,

Dimensional Formula of Hubble constant = M0L0T-1
SI Unit of Hubble Constant is sec-1.

What is Dimensional Formula of Radiation pressure ?

Radiation pressure is the pressure associated  with the interaction of electromagnetic radiation on any given surface. In other words Radiation pressure is defined as force per unit area exerted by electromagnetic waves.

Mathematically,

Radiation Pressure = Force / Area =  Intensity of wave (I) / Speed of light(c) .

Dimensional Formula of Intensity of wave = M1L0T-3
Dimensional Formula of Speed of light = M0L1T-1

Putting these values in the given equation we get,

Dimensional Formula of Radiation pressure = M1L-1T-2
SI Unit of Radiation pressure is N/m2 (newton per square meter)
