Answer:
B.the same as Lily's.
Explanation:
When a disc is rotating on its axis uniformly with some angular velocity , every particle on it rotates with the same angular velocity , because every particle on it completes a rotation simultaneously . So in one rotation they take same time . Hence particles whether on the outer edge or near the axis , all have same angular velocity .
They but differ due to their different linear velocity . Linear velocity of particle near outer edge have greater magnitude. .
Answer: False, not all matter we encounter in everyday life exists in one of the three physical forms.
When air is blown across the top of an open <span>water bottle, air molecules in the bottle vibrate at a particular frequency and sound is produced in a process called "refraction".

Answer: set up a reminder so you won't forget also try clearing your schedule so you can have more time
<span>We can use the equation for the force of gravity to solve this question.
F = G M1 M2 / R^2
Let R be the radius of the planet.
f0 = G M1 M2 / (2R)^2
f0 = (1/4) x (G M1 M2 / R^2)
We can find an expression for f2.
f2 = G M1 M2 / (4R)^2
f2 = (1/16) x (G M1 M2 / R^2)
We can express f2 in terms of f0:
f2 = (4/16) x f0
f2 = 0.25 f0</span>
