a) 32.3 N
The force of gravity (also called weight) on an object is given by
W = mg
where
m is the mass of the object
g is the acceleration of gravity
For the ball in the problem,
m = 3.3 kg
g = 9.8 m/s^2
Substituting, we find the force of gravity on the ball:

b) 48.3 N
The force applied

The ball is kicked with this force, so we can assume that the kick is horizontal.
This means that the applied force and the weight are perpendicular to each other. Therefore, we can find the net force by using Pythagorean's theorem:

And substituting
W = 32.3 N
Fapp = 36 N
We find

c) 
The ball's acceleration can be found by using Newton's second law, which states that
F = ma
where
F is the net force on an object
m is its mass
a is its acceleration
For the ball in this problem,
m = 3.3 kg
F = 48.3 N
Solving the equation for a, we find

Both objects have the same electrical charge. Opposite charges attract. And if they were neutral they would not do anything.
Answer:

Explanation:
Which sentence from the passage shows that the function of the river depicted here has carried through to modern times?
Explanation:
1.
the rate at which something occurs over a particular period of time or in a given sample.
"an increase in the frequency of accidents due to increased overtime"
2.
the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light).
"different thicknesses of glass will absorb different frequencies of sound"
