Answer:
A
Explanation:
Well, the electricity starts it's move from the positive terminal to the negative terminal, So it's clockwise.
and the resistances ain't parallel, so the gon be in series.
your answer gon be choice A
Answer:
E = 12262 V/m
Explanation:
given,
Charge of the particle, q = +4.0 μC
mass of the ball, m = 5 g
Electric field, E = ?
Force due to weight
F = m g
Force due to electric field
F =q E
To balance the weight of particle both the forces must be equal
Electric field exerted on the ball will be equal to
m g = q E


E = 12262 V/m
Hence, the electric field acting in the particle is equal to E = 12262 V/m
Answer:

Explanation:
By using relation,
Speed of light = frequency × wavelength (in m)

An electron is emitted from a nucleus- State the effect this has on the charge of the nucleus
Answer:
an electron orbiting around the nucleus combines with a nuclear proton to produce a neutron, which remains in the nucleus, and a neutrino, which is emitted. As in positron emission, the nuclear positive charge and hence the atomic number decreases by one unit, and the mass number remains the same.
hope this helps!!!
