Answer:
85.62 m
168.75 years
101.04 years
Explanation:
= Length of ship = 143 m
v = Velocity of ship = 0.8c
c = Speed of light
s = Distance to Boralis orbit = 135 ly
Gamma value
Length contraction is given by
The length is 85.62 m
Time taken
Time taken from the perspective one Earth is 168.75 years
Time dilation is given by
The time taken from the perspective of the ship is 101.04 years
Electrons in an iron atom (or in any atom) cannot settle all together into the lowest energy state because of Pauli exclusion principle: this principle states that two or more identical fermions (and so, electrons included) cannot occupy the same quantum state of a system at the same time.
The current in the motor is 17.27 A
<h3>What is power?</h3>
power refers to the ability to do work. however as considered in physics is the product if current and voltage. The unit of power is Watts while the unit of current is in Ampere
<h3>What is efficiency?</h3>
efficiency is the ratio of work output to work input expressed in percentage
<h3>how to calculate for current in the motor</h3>
<u>Given data</u>
power output of 2.50hp
efficiency = 90..0%
current = power input / voltage
power input = output power / efficiency
= 2.5 / 90
= 2.778 hp
converting hp to watt gives
2.778 * 746
2072.388 W
current = 2072.388 / 120
current = 17.27 A
