Answer:
Give up.
Explanation:
Physics is horrible.
And that's the cold hard truth. :(
Answer:
Explanation:
No external force is acting on uranium nucleus so we can apply law of conservation of momentum . If M and m be the mass of bigger and smaller fragments respectively and V and v be their velocity after fission , Total momentum after fission = total momentum before fission
MV - mv = 0 , since the nucleus was at rest , its momentum before fission is zero . negative sign of mv is taken because smaller fragment will move in opposite direction to that of bigger fragment .
MV = mv
M / m = v / V
M > m
Hence,
v > V
So velocity of smaller fragment will be higher .
Energy can be transferred mechanically through the movement of the parts in machines, and when the motion or position of an object changes. Sound waves and seismic waves (formed during earthquakes) are mechanical waves that transfer energy through materials and from place to place.
Hope This Helps :)
Answer:
The answer to your question is: F = 70 pounds
Explanation:
To calculate the net force, only substract the left value to the right value.
F = F right - F left
F = 100 p - 30 p
F = 70 pounds
