Compared with an Earth year, a galactic year represents time on a grand scale but its not a consistent measurement across the galaxy
I'm pretty sure it's the neutron star.
Answer:
Meteoroids
Explanation:
Meteoroids are small masses of rocks or metallic bodies that often found to orbit around the Sun. The size of a meteoroid is smaller in comparison to the asteroids. The elements that are found in the meteoroids are extraterrestrial nickel and iron. Meteoroids are often formed by the fragments from bodies present in universe such as Mars or Moon and thrown into space by an impact. After formation they often come in the range of attraction of Sun and start orbiting around it.
The answer is silver. Silver is the most dense, it's a solid so it is more compact and is obviously the most likely to have more mass to it.
Answer:
Correct answer: Third statement P = 4900 W
Explanation:
Given:
m = 500 kg the mass of the elevator
h = 10 m reached height after t = 10 seconds
P = ? power of the motor
The formula for the calculating power of the motor is:
P = W / t
since work is a measure of change in this case of potential energy then it is:
W = ΔEp = Ep - 0 = Ep
In this case we must take g = 9.81 m/s²
Ep = m g h = 500 · 9.81 · 10 = 49,050 W ≈ 49,000 W
Ep ≈ 49,000 W
P = Ep / t = 49,000 / 10 = 4,900 W
P =4,900 W
God is with you!!!
