Answer:
159241.048 cm³/s
Explanation:
r = Radius = 3×height = 3h
h = height = 16 cm
Height of the pile increases at a rate =
Differentiating with respect to time
∴ Rate is the sand leaving the bin at that instant is 159241.048 cm³/s

Answer:
(d) 0.07 m/s
Explanation:
Given Data
Snowball mass m₁=0.15 kg
Ice skater mass m₂=65.0 kg
Snowball velocity v₁=32.0 m/s
To find
Velocity of Skater v₂=?
Solution
From law of conservation of momentum
So Option d is correct one
Complete Question
The complete question is shown on the first uploaded image
Answer:
Explanation:
From he question we are told that
The first mass is
The second mass is
From the question we can see that at equilibrium the moment about the point where the string holding the bar (where are hanged ) is attached is zero
Therefore we can say that
Making x the subject of the formula
Looking at the diagram we can see that the tension T on the string holding the bar where are hanged is as a result of the masses ()
Also at equilibrium the moment about the point where the string holding the bar (where () and are hanged ) is attached is zero
So basically
Making subject
