Answer:
He requires 1 gram of mass.
Explanation:
The density is defined as:
(1)
Where m is the mass and V is the volume.
Then, m can be isolated from equation 1 in order to determine the mass.
(2)
Hence, he requires 1 gram of mass.
Answer:
The force of gravity on a 700 kg satellite if its 10 km above Earth's surface is given by
=
= 3984378 m / 
Explanation:
The force of gravity on a 700 kg satellite if its 10 km above Earth's surface is given by
=
= 3984378 m / 
The equivalent of the Newton's second law for rotational motions is:

where

is the net torque acting on the object

is its moment of inertia

is the angular acceleration of the object.
Re-arranging the formula, we get

and since we know the net torque acting on the (vase+potter's wheel) system,

, and its angular acceleration,

, we can calculate the moment of inertia of the system:
Yes they can.
Don't really know any examples
