Answer:
we assume that it starts with a velocity of 10m/s. At 2m height above ground level, its velocity decreases at 3m above ground level
for its way down the velocity at 3m on its way down is more than its velocity at 2m on its way down.
Explanation:
A student throws a small rock straight upwards. The rock rises to its highest point and then falls back down. How does the speed of the rock at 2m on the way down compare with its speed at 2m on the way up?
It decreases in speed on its way down and increases in speed on its way down.
it decreases in speed on its way up because the the vertical motion is against the earths gravitational pull on an object to the earth's center
.It increases in speed on his way down because its under the influence of gravity
from newton's equation of motion we can check by
using V^2=u^2+2as
we assume that it starts with a velocity of 10m/s. At 2m height above ground level, its velocity decreases at 3m above ground level
for its way down the velocity at 3m on its way down is more than its velocity at 2m on its way down.
I think that would be c) mirror because mirrors reflects light and can't create it.
Answer:
which language is these
Explanation:
we only use english , Hindi ,tamil , bengali and Malayalam
please tell us that it is which language. From that we will slove this
Answer:
A. It will increase
Explanation:
Area of a wire is:
R = ρL/A
where ρ is the resistivity of the wire,
L is the length of the wire,
and A is the cross-sectional area.
If A decreases, while ρ and L stay the same, then R will increase.
