A 100 kg box sits on an incline held at rest by a very thin rope attached to another mass hanging as shown. The force of frictio
MAVERICK [17]

If friction is acting along the plane upwards

then in this case we will have

For equilibrium of 100 kg box on inclined plane we have

mgsin\theta = F_f + T

also for other side of hanging mass we have

T = Mg = 50(9.8) = 490 N

now we have

100(9.8)sin\theta = 100 + 490

980sin\theta = 590

sin\theta = 0.602

\theta = 37 degree

In other case we can assume that friction will act along the plane downwards

so now in that case we will have

mgsin\theta + F_f = T

also we have

T = Mg = 50(9.8) N

now we have

100(9.8)sin\theta + 100 = 50(9.8)

980sin\theta + 100 = 490

980 sin\theta = 490 - 100

sin\theta = 0.397

\theta = 23.45 degree

<em>So the range of angle will be 23.45 degree to 37 degree</em>

3. Will the weight of a kg of iron in air and the weight of a kg of cotton in air
larisa [96]

Answer:

A kg of cotton is heavier.

Explanation:

Because in air, cotton gets upthrust that's why weighing machine gives less weight than its actually have.

for eg: If cotton has 800g weight, the machine shows a kg(1kg) when measure in air due to upthrust.

I hope this will be helpful for you.

In physics, when a baseball player catches a ball, which one of newtons laws is it an example of?
OLEGan [10]
Its C newtons 3rd law, because both the ball and the player are exerting a force. The ball is exerting a force on the player and the player is exerting a force to bring the ball to a rest or a state where it isn’t moving.
