Answer:
6.03 m
Explanation:
First of all, let's convert the angular velocity from revolutions per minute to radians per second:
The frictional force on the block ranges from zero to a maximum value of
In order for the block to remain stuck on the turntable, the frictional force must be equal to the centripetal force, so we can write:
where
m is the mass of the block
is the angular velocity
r is the distance of the block from the centre
is the coefficient of static friction
g = 9.8 m/s^2
Solving for r, we find:
Answer:
because the gas within the black box will absorb more heat than that in the surrounding
Explanation:
this is because the black color has a tendency of absorbing heat
The average speed of the car would be 50 mph
a) the distance an object moves to the amount of time needed to travel the distance.
