The power of the engine is 320 W.
<u>Explanation:</u>
Power may be defined as the rate of doing work (or) work done per unit time. One unit of energy is used to do the one unit of work.
Power = Work done / Time taken
Given, Force = 80 N, height = 5 m , final velocity = 4 m/s
To calculate the power, we must know the time taken.
To find the time, use the distance and speed formula which is given by
Time = Distance / speed
Here distance = 5 m and speed = 4 m/s
Time = 5 / 4 = 1.25 s.
Now, Power = work done / time
= (F * d) / t = (80 * 5) / 1.25
Power = 320 W.
The standard unit of power is watt (W) which is joule per second.
Answer:
By holding another magnet close to it. If the object is attracted to the magnet, then it too is magnetic.
Use conservation of momentum ;
m1u1 + m2u2 = m1v1 + m2v2
1200×15.6 + 0 = 2700v
v = 18720/2700
v = 6.933 or ~ 7 m/s
Answer:
athe answer to this question is Synex BA-315
Answer:
Power, P = 162.53 Watts
Explanation:
Given that,
Mass, m = 200 g = 0.2 kg
Initial speed of the snake, u = 0
Final speed of the snake, v = 32 m/s
Time, t = 0.63 s
Power of an object is given by :
P = 162.53 Watts
So, the power of the rattlesnake is 162.53 Watts. Hence, this is the required solution.
