Answer:
15
Explanation:
0.15 is a decimal place after a 0, whereas the 15 is a whole number
A circuit breaker may need to switch short circuit currents as high as <u>fifteen (15)</u> times its rated current.
<u>Rated current</u> is basically the<u> maximum limiting current</u>. If the current exceeds its maximum limit, there will be overheating and, in severe circumstances, a <u>short circuit</u> will result.
A<u> circuit breaker</u> is a type of <u>electrical safety</u> device used to guard against short circuit damage to an electrical circuit.
An example of circuit breakers that are most frequently used in low voltage circuits is <u>Miniature Circuit Breakers</u> (MCBs).
These are the switches that automatically turn off when the current in a circuit exceeds the<u> safe limit</u>.
So, to ensure complete protection against <u>short circuits</u> & <u>overloading</u>, a circuit breaker may need to switch short circuit current as high as fifteen times its rated current.

Answer:
W = 7591.56 J
Explanation:
given,
distance of the box, d = 37 m
Force for pulling the box, F = 217 N
angle of inclination with horizontal,θ = 19°
We know,
Work done is equal to product of force and the displacement.
W = F.d cos θ
W = 217 x 37 x cos 19°
W = 7591.56 J
Hence, the work done to pull the box is equal to W = 7591.56 J
Answer:
A
Explanation:
density is defined to be as the mass per unit volume therefore you divid the mass by the volume
Answer:
the energy emission process is due to nuclear fusion
Explanation:
In the planetary system the energy emitted by bodies is a part of the energy received by a hot body (star), this star is what creates the entire energy cycle of a given planet. This creates the entire tidal movement, continental drift
If the planets reach a certain size the gravitational force near their center is so great that the atoms are crushed and some beginnings of fusion processes are formed where some atoms are transformed from hydrogen to helium releasing a certain amount of energy and heat that believe that the planet emits more energy than it receives from its star.
In summary, the energy emission process is due to nuclear fusion
