Answer:
a) Acceleration = 7.41 m/s^2
b) Distance ran = 6.75 m
Explanation:
For Acceleration use the formula...
a = (v - u) ÷ t....where v=10 and u=0....and t=1.35
a = (10 - 0)÷ 1.35
;acceleration = 7.41m/s^2
For the distance moved in 1.35s
;use the...s = ut + 1/2at^2....where s is the distance moved
;s = (0)(1.35) + 0.5(7.41 × 1.35^2)
Distance moved = 6.75m
Answer:
Explanation:
500 MW = 500 X 10⁶ J / s
If R be the rate of heat supplied and 35 % is the efficiency of conversion
R x .35 = 500 X 10⁶
R = 500 X 10⁶ / .35
= 1428.57 x 10⁶ J / s
b )
Rate of heat going waste
= .65 x 1428.57 x 10⁶
= 928 .57 x 10⁶ J / s
c )
Heat content of coal = 30 x 10⁶ J /kg
1428.57 x 10⁶ J of heat will come from
= 1428.57 x 10⁶ J / 30 x 10⁶ J /kg
= 47.62 kg per second
= 47.62 x 24 x 60 x 60 = 4114368 kg in one day
= 4114368 / 907.185 ton per day
= 4535.31 ton per day
d ) Fuel consumption rate will decrease by 12.5 % if thermal efficiency is increased to 40 % .

Answer :B,kgm²/s³
Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
Simple theory.
