Answer:
Rotational inertia of the object is given as
Explanation:
As we know that the acceleration of the object on inclined plane is given as
now we know that velocity at any instant of time is given as
now we know that if the graph between velocity and time is given then the slope of the graph will be same as acceleration
so here we have
now from the graph slope of the graph is given as
now rotational inertia is given as
An electrical <span>current is </span>caused<span> by </span>flow<span> of free electrons from one atom to another. </span>
Here when car in front of us applied brakes then it is slowing down due to frictional force on it
So here we can say that friction force on the car front of our car is given as
So the acceleration of car due to friction is given as
now it is given that
so here we have
so the car will accelerate due to brakes by a = - 8.52 m/s^2
Answer:
and
Explanation:
The wavelength of a visible light is 727.3 nm.
The formula is as follows :
f is the frequency of the visible light
Energy of a photon is given by :
E = hf, h is Planck's constant
Red color has a frequency of and energy per photon is .
