If the ball weighs 5 newtons, then that's the force of gravity that
attracts it to the center of the Earth. The force only depends on
the mass of the ball and its distance from the center of the Earth.
The force of gravity doesn't care whether the ball is moving or at
rest. It doesn't change significantly until the ball moves to some
significant distance off the Earth's surface, which isn't happening
if it's tossed by a human being.
So we have a downward force of 5 newtons on the ball at all times.
In order to find the net force on it, we have to identify any other
forces besides gravity that are also acting on it.
If the ball were moving through the air, then there would be a force
of air resistance on it, acting opposite to its motion. But when it's
at its maximum height, in the process of turning around from rising
to falling, there's an instant when it's not moving through the air at all,
so gravity is the only force acting on it. At that moment, the net force
on the ball is 5.0 newtons downward.

Answers
It will definitely help you.
Answer:
c.exists as a crystalline solid
Explanation:
Amongst all the three phases, it is solid phase which is the most compact because the atoms within the solids are bound with a very strong force of attraction. But, solids can exist as either crystalline solid or amorphous solid. Between these two type of solids, it is crystalline solids which are very well packed and the inter atomic distance between their two atoms is the least. It is due to the reason that the atoms within a crystalline solid are arranged in proper order in the form of stacks. But, in amorphous solids the atoms are not arranged properly i.e. their arrangement is random which leads to the increased inter atomic distance. Second comes liquid phase, in liquids the inter atomic forces are intermediate between solids and gases. Atoms in a gas are bound with the weakest force of attraction known as van der Waals that is why the distance between the atoms of a gas is the highest.

b. If the cd rotates 4 times per second, what is the linear speed of a point on the outer edge of the cd? Give
your answer in meters per second.
c. What is the linear speed of a point 3 centimeters from the center of the cd? (Assume the angular speed
has not changed).
Answers
Speed is 4 times that. That is, 150.8 cm/s or 1.508 m/s.
If we get a point at distance 3 cm, we take the radius half of that. The circumference also gets half, so does the linear speed. We get 0.754 m/s or 75.398 cm/s.
