Answer:
option C
Explanation:
given,
Range is doubled
for range to be doubled height should become 4 times.
formula to calculate the horizontal range
R = v T_{flight}
using equation of motion


now,

where, h is the height of the
Assuming the height be equal to 0.6 m
to calculate the new height



hence, the correct answer is option C
The correct answer is option D

Answer: 5,640 s (94 minutes)
Explanation:
the tangential speed of the HST is given by
(1)
where
is the length of the orbit
r is the radius of the orbit
T is the orbital period
In our problem, we know the tangential speed:
. The radius of the orbit is the sum of the Earth's radius and the distance of the HST above Earth's surface:

So, we can re-arrange equation (1) to find the orbital period:

Dividing by 60, we get that this time corresponds to 94 minutes.
I think you mean the Cryosphere?
But the answer is D- Earths Ice
This word Cryosphere comes from the greek word "kryos" which means cold
Many people think of the cryosphere as being the north and south poles but snow and ice can be found in a lot of places on the Earth
