Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Part 5)
Explanation:
Part a)
Initial angular momentum of the merry go round is given as
here we know that
now we have
Part b)
Angular momentum of the person is given as
so we have
R = 1.99 m
so we have
Part 3)
Angular momentum of the person is always constant with respect to the axis of disc
so it is given as
Part 4)
By angular momentum conservation of the system we will have
Part 5)
Force required to hold the person is centripetal force which act towards the center
so we will have
<span>It all starts from a radio with a loudspeaker . It produces and converts electrical energy and make this a formed of kinetic energy coming out of the speaker. Then, when this kinetic energy is moving and transferred to surroundings or air, it will let people feel the motion being created by the air. Finally, it reaches the people and hears this as sound.
This is an example on how we trace the transformation of on signal from radio and how it reaches to people as sound or as a music.</span>
Nitrogen has 7 protons and neutrons
Answer:
a = 40 m / s²
Explanation:
This is a kinematics problem, where we must use both linear and angular and the relationship between them
we'll eat by reducing the angular velocity to units if
w = 1.0 rev / s (2pi rad / 1 rev) = 2pi rad / s
they ask us for linear acceleration, we use the relationships between linear or angular variables
a = α R
a = 20 2
a = 40 m / s²
