Answer:
735watts
Explanation:
Power = Force*distance/time
Given
Force = mg = 50 * 9.8'
Force = 490N
distance = 3m
time = 2s
Substitute
Power = 490*3/2
Power = 1470/2
Power = 735Watts
Hence the minimum power output is 735watts
Amplitude, is the answer to the question
Answer:
65 m/s
Explanation:
v=v0+at <=> v = 11 + 12 t ∧ t = 4.5 s <=> v = 11 + 12×4.5 <=> v = 65 m/s
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
