Answer:
0.02
Explanation:
Force,
where N is normal reaction and coefficient of kinetic friction is
. Also, N is equivalent to mg ie N=mg where m is mass of an object and g is acceleration due to gravity. Making
the subject of the formula then

Substituting F with 2 N, m with 10 kg and g with 9.81 then

Answer:
Explanation:
Kinetic energy is one of the types of mechanical energy and it is the energy due to the object in motion.
Kinetic energy is given as 1/2mv^2
A body cannot have a K.E when it is not in motion because of the velocity
Velocity is the change is position of an object or particle with time taken, so if the object doesn't change it position then it won't have velocity.
kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
C. white light
Explanation:
All the visible color light waves are seen together and makes up a white light.
Visible light is made up of different colors and when they join together they are seen as the white light around us.
- During rainbow formation, we see the different colors of light that makes up a white light.
- when white light passes through a glass prism, the velocity and wavelength changes and we can see the different components of light.
