Answer:
0.18 MN
Explanation:
m = Mass
t = Time taken
u = Initial velocity = 0
v = Final velocity = 1 km/s
= Mass flow rate = 180 kg/s
Force is given by
The thrust on the rocket is 0.18 MN
D) earthquakes are caused by movement of the crust along plate boundaries
Answer:
93312000 Joules
Explanation:
Energy can be explained as the capacity for doing work. And can be expressed as
E= pt....................eqn(1)
Where
E= Energy in Joules
P= power in Watt= 2.00W
t= time in seconds
Time= 18 months, which can be converted to "seconds" as;
18 months = [ 18 monthsx 30 days x 24 hours x 60 min x 60 sec] = 46656000
Then
time= 46656000 seconds
Power=2 watt
If we substitute into equation (1) we have
Energy = 2 watt × 46656000 seconds
Energy= 93312000 Joules
From solid to liquid. also known as melting
from solid to gas known as sublimation
They would be walking 60 Meters a minute.
Hope it helps!
