avanturin [10]

Answer:

Explanation:

We know that , If the frictional force on a system is zero , then the total energy of a system will be conserved.

By using energy conservation

KE₁ + U₁ = KE₂ + U₂

KE₁=Kinetic energy at location 1

U₁ =Potential energy at location 1

KE₂=Kinetic energy at location 2

U₂=Potential energy at location 2

Therefore, Raymond is thinking in a right way.

The drawing shows three objects rotating about a vertical axis. The mass of each object is given in terms of m0, and its perpend

photoshop1234 [79]

Answer:

I₁ > I₃ > I₂

Explanation:

Taking the pic shown, we have

m₁ = 10m₀

m₂ = 2m₀

m₃ = m₀

r₁ = r₀

r₂ = 2r₀

r₃ = 3r₀

We apply the formula

I = mr²

then

I₁ = m₁r₁² = (10m₀)(r₀)² = 10m₀r₀²

I₂ = m₂r₂² = (2m₀)(2r₀)² = 8m₀r₀²

I₃ = m₃r₃² = (m₀)(3r₀)² = 9m₀r₀²

finally we have

I₁ > I₃ > I₂

What is the minimum tangential velocity a space station would need to simulate earth gravity if the radius is 50 meters ?

Aneli [31]

Explanation:

angular velocity is given by

$w = \sqrt{ \frac{g}{r} }$

$w = \sqrt{ \frac{9.8}{25} }$

w = 0.626

now tangential velocity is

V = rw

= 25 x 0.626

= 15.65 m/s
