Bag of feathers because it weighs the least
Answer:
B. Along this path the gravitational potential energy of the system is never zero.
D. At every location along the comet's path the gravitational potential energy of the system is negative.
E. The sum of the kinetic energy of the system plus the gravitational potential energy of the system is the same at every location along this path.
Explanation:
Gravitational potential energy of the system is given as
now we know that
since the system is bounded to move together so the total mechanical energy must be negative
so sum of kinetic energy and potential energy must be negative at all locations.
Also we know that that potential energy is always non zero and a negative quantity here.
Answer:
491.919561014 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²
The distance at which the fuel runs out is 127.294405 m
The distance covered after the engine turns off is 364.625156014 m
Total distance above the ground is 364.625156014+127.294405 = 491.919561014 m
Answer:
because the presure it puts on your body same as if you go to deep in the water
