The power is equal to energy transferred per unit time.
So, here power will be due to potential energy of the water kept at a certain height. And water is flowing down at the given flow rate.
The flow rate of water is 200kg/s
And the height given is : 15m
So, we calculate the potential energy as: mgh
Where m is the mass,
g is acc due to gravity = 9.8m/s
h is the height
So, potential energy = 200kg*9.8*15
= 29,400 J
Therefore, the maximum power generated is 29400 J/sec = 29400 Watts
I think the correct answer from the choices listed above is option C. The scatter plot above shows the relationship between the pressure and volume of a gas in which the <span>pressure of a gas increases as its volume decreases. However, they are not linearly related. Hope this answers the question.</span>
<span>Time needed for drive a distance 100 km at 100 km/h:
t1 =100/100
= 1 h
Time needed for drive a distance 40 km at 45 km/h:
t2 =40/45
=0.8 h
t3 =3h 15m - 1 h- 0.8 h
=1.45 h
Distance to town equals:
s3 =270-100-40
=130 km
Least speed needed to arrive in time for the interview:
v3 =130 km/1.45 h
=89.65 km/h
The answer is 89.65 km/h</span>
In this scenario, only conservative force is acting on the ice-cream hence energy is conserved.
Now, you know that ice-cream was held at a height of 1.75 m from ground. Taking ground( h= 0 meters) as reference,
Total energy of ice-cream before it fell = Total energy after it reached the ground.
Once ice-cream falls, all its GPE is converted into kinetic energy. Kinetic energy will be maximum just before it hits the ground. And since ice-cream is inelastic substance, it will come to at rest. That is, its GPE will be zero on the ground
<span>Well, light gathering capacity of a telescope is dependent upon the area of aperture</span>
