Answer:
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
Explanation:
The system formed by the masses is isolated so its angular momentum is conserved
initial instant, which throws the mass with angular velocity o and radius ro
L₀ = I w₀
final instant. When the mass has a radius r and an angular velocity w
L_f = I_f w
Lo = l_f
I₀ w₀ = I_f w_f
let's analyze this result
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
Answer:
When light gets in contact with water, it emerges into the air, and then it speeds up, which makes it look shallower than it actually is.
Explanation:
Given that,
Angle = 30°
Initial velocity = 15 m/s
We need to calculate the time of flight
Using formula of time of flight
Where, u = initial velocity
g = acceleration due to gravity
Put the value into the formula
We need to calculate the final velocity of the ball
Using equation of motion
Hence, The final velocity of the ball is 29.7 m/s.
The statement that describes an atomic nucleus best is that an atomic nucleus contains most of the atom's mass.
