Answer:
energy per unit charge
Explanation:
EMF is energy per unit charge and has unit joule/ coulomb, where joule is unit of energy and coulomb is the unit of charge.
Answer:
its b option balance hi your last question
Answer:
One object has a large mass, and the objects are close together.
Answer: the momentum is increased
Energy and momentum are conserved, this was proved by he American physicist Arthur H. Compton after his experiments related to the scattering of photons from electrons (Compton Effect), in which he also proved that photons do have momentum.
So, this momentum is given by the following expression:
Where is the Planck constant and is the wavelength of the photon.
As we can see, the momentum is inversely proportional to to the wavelength. This means, if <u>decreases</u>, <u>increases</u>.
Answer:
it means the velocity is changing.
the rate of change of velocity is acceleration
so it means the body is accelerated at 2m/s^2
