Answer:4800 kWh
Explanation:
Given
Power output of station =2,00,000 W or 200 kW
because 1 kW=1000 W
For 24 hours, it will generate 
Speed = 11000 m/s = 11km/s
D = 380000 km,
t = D/s = 380000 km/ 11km/s
t = 34 545.45 seconds.
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that the target is at distance 75 m from the hunter position
so here we will have

here we know that

so we have


now in the same time bullet will go vertically downwards by distance



Part b)
In order to hit the target at same level we need to shot at such angle that the range will be 75 m
so here we have



Answer:
is the drop in the water temperature.
Explanation:
Given:
- mass of ice,

- mass of water,

Assuming the initial temperature of the ice to be 0° C.
<u>Apply the conservation of energy:</u>
- Heat absorbed by the ice for melting is equal to the heat lost from water to melt ice.
<u>Now from the heat equation:</u>

......................(1)
where:
latent heat of fusion of ice 
specific heat of water 
change in temperature
Putting values in eq. (1):

is the drop in the water temperature.
