Answer:
Explanation:
pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
Answer:
10.2 kg
Explanation:
Assuming the object is on Earth:
w = mg
m = w / g = 100 / 9.81 = 10.2kg
Answer:
because it decrsces the force of momentome by sliding on the ice.
Explanation:
Answer:
Explanation:
m = Mass of person = 65 kg
d = Diameter of round table = 6.5 m
r = Radius = 
v = Velocity of person running = 3.8 m/s
= Moment of inertia of turntable = 
Moment of inertia of the system is
As the angular momentum of the system is conserved we have
The angular velocity of the turntable is .
