Answer: student b ran up the stairs faster
Explanation:if they were going up the same stair case and student b got up there faster that means he was running therefore student b was using more power
Answer:
B) Angular velocity
Explanation:
The equivalent of Newton's second law for the rotational motions can be written as:

where
is the net torque applied to the object
I is the moment of inertia
is the angular acceleration
From the formula we see that when a constant net torque
is applied, then the object also has a constant angular acceleration,
.
But we also know that

where
is the angular velocity: so, a constant angular acceleration means that the angular velocity of the object is changing, so the correct answer is
B) Angular velocity
(moment of inertia and center of gravity do not change since they only depend on the mass and the geometry/shape of the object, which do not change)
Answer:
909.1 m
Explanation:
Rate of temperature increase with 100 m elevation = 1°C
h = Maximum Height
Adiabatic lapse rate = -0.65°C/100 m
We have the relation

The maximum height is 909.1 m
