Answer:
I'm not sure but I think it's 4.5 v
Answer:
Power = 377.35 W or Power = 0.5065 hp
Explanation:
Given:
Number of steps, n = 1576
height of each step, h = 0.20 m
Total height achieved, H = nh = 1576 × 0.20 = 315.2 m
Mass of the runner, M = 70.0 kg
Total time taken, t = 9 minutes 33 seconds = (9 × 60) + 33 = 573 seconds
Now, the potential energy gained by the runner,
E = MgH
where, g is the acceleration due to the gravity
on substituting the values in the above formula, we get
E = 70 × 9.8 × 315.2
or
E = 216227.2 J
also,
Energy = Power × time
therefore,
Power = Energy/time
or
Power = 216227.2 J / 573
or
Power = 377.35 W
Now,
745 watt = 1 hp
or
1 watt = 1/745 hp
thus,
Power = 377.35 W = 337.35 × (1/745) hp
or
Power = 0.5065 hp
Answer:
Two mass nuclei are joined to form one nucleus
Explanation:
As the name implies "fusion", it is the joining of lighter nucleus to form a heavier nucleus to produce energy
Explanation:
<u>Using Equations of Motion</u> :
(1) v = u + at
24 = 6.5 + a * 210
<u>a (Acceleration) = 0.083 m/s^2 </u>
<u>(</u><u>2</u><u>)</u><u> </u> v^2 = u^2 + 2aS
S = 576 - 42.25 / 0.166
<u>S (Distance travelled) = 3215.3 m </u>
(Option A seems a typo since the answer is 3215.3 m)
Answer:
If the force exerted by the intern is doubled and the distance is halved, the work done by the intern remains the same. Work done is the force applied to move a body through a distance.
