Answer:
<u><em>375 J</em></u>
Explanation:
<u><em>Total energy</em></u> = 750 J
<u><em>Efficiency</em></u> = 50%
<u><em>Wasted energy</em></u> = 50% [100% - 50%]
<u><em>Amount of wasted energy</em></u>
= 750 x 50%
= 750 x 0.5
= 375 J
Answer:
Explanation:
Given
Weight of helicopter 
inclination of blades with vertical 
Suppose 
is the lifting Force
Now using F-B-D
as helicopter is moving with constant velocity
balancing forces in Vertical Force
Now sin component of lift is air resistance
where R=air resistance
I'm not too sure about this one, I've been having second guesses on it myself. But, what I put is A. Velocity. That could be wrong though, so don't take my word for it! ;)
A low-luminosity star has a small and narrow <u>habitable zone</u>, whereas a high-luminosity star has a large and wide one.
<h3>What is luminosity of a star?</h3>
The radiant power emitted by a light-emitting item over time is measured as luminosity, which is an absolute measure of radiated electromagnetic power (light).
The total quantity of electromagnetic energy released per unit of time by a star, galaxy, or other celestial object is referred to as luminosity in astronomy.
