Divide 2500 g by 500 cc. The quotient is 5 g/cc ... the density.
Answer: Its The Force Of Gravity
I hope this helps :)
Answer
Given,
time = 8 s
θ = 17.5 rad
initial angular velocity = 0 rad/s
Using rotational motion equation
a. angular acceleration 
b. Average angular velocity = total angle/total time taken
=
= 2.187 rad/s
c. we have,
Angular velocity at end of 8 seconds 
rad/s
d. we have, additional angle in next 8 seconds:
rads
<span>If only one force is acting an object it can have zero acceleration but it cannot have zero velocity. This occurs because acceleration is a change in speed, therefore when one force is acting upon the object the speed will remain constant. It can't have zero velocity because if one force is acting upon it then it is moving and no matter what that means it will have a velocity that isn't zero.</span>
Answer:
They come in different kinds, called elements, but each atom shares certain characteristics in common. All atoms have a dense central core called the atomic nucleus. ... All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is.
