A light bulb is supplied with 100 J of energy each
second.
a How many joules of energy leave the bulb
each second in the form of heat and light?
b If 10 J of energy leave the lamp each second
in the form of light, how many joules leave
each second in the form of heat?

The amount of property that is needed by a body or an object to work is called energy. It is conserved and can only be transferred from one object to another. It is estimated in Joules, calories or kW -h.

The energy that leaves the lamp is a. 95 J and b. 90J.

This can be estimated as:

a. According to the conservational law of energy:

Given,

Substituting values in the equation:

b. Applying the same law:

Given,

Substituting values:

Therefore, energies released are a. 95 J and b. 90J.

a.95J

b.90J

Explanation:

a.Applying energy conservation laws:-

Energy  Into Bulb=

Given  that light energy=5J,and Total Energy=100J

b. Applying the laws in a above.

Total Energy=100J

Light Energy=10J

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
