Explanation:
the answer is y=strong winds move sand dunes in the desert
No work is being performed on the object unless the object is moving, as work done = force x distance
Answer:
density = 0.0933 kg/m
speed = 27.581 m/s
Explanation:
given data
length L = 4.5 m
mass m = 0.42 kg
force F = 71 N
to find out
mass density and speed
solution
we find linear mass density
linear mass density = mass / length
put here all value
density = 0.42 / 4.5
density = 0.0933 kg/m
and
speed of wave
speed = √(F/density)
speed = √(0.42/0.933)
speed = 27.581 m/s
Answer:
physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time
