If a 96 n force of gravity is happening to a falling basketball what is the ball mass? The accelydue to gravity is 9.8m/s^2
Answer:
9.80 kg
Explanation:
F = ma
96 N = m(9.8 m/s^2)
m = 9.80 kg
The mass of the ball will be m= 9.8 kg
What is Newton's second law of motion?
It states that the force is equal to the rate of change of momentum . For a constant mass , force is equal to mass times acceleration
given :
Force due to gravity = 96 N
g = acceleration due to gravity = 9.8 m /s^2
using Newton's second law of motion
Since , F = ma
96 = m g
m = 96/9.8
m= 9.8 kg
The mass of the ball will be m= 9.8 kg

1.A motorcycle’s velocity at the top of the hill is 11.0 m/s. 4.0 seconds later it reaches the bottom of the hill with a velocity of 20.0 m/s. What is the acceleration of the motorcycle?
2.A motorcycle’s velocity at the top of the hill is 11.0 m/s. 4.0 seconds later it reaches the bottom of the hill with a velocity of 20.0 m/s. What is the acceleration of the motorcycle?
Answer:
1) as far as I remember
Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time
So we would use this formula a=vf-vi/t
So 20-11/4

What's Inertia ????☁️☁️
Explanation:
the inability to change the position from rest to motion or motion to rest by themselves is inertia.
Answer:
Inertia is the property of a body in rest to resist motion or a body in motion to continue to its state of motion unless acted by external forces.
What is the relationship between potential and kinetic energy and electricity
Answer:
The primary relationship between the two is their ability to transform into each other. In other words, potential energytransforms into kinetic energy, andkinetic energy converts into potential energy, and then back again.

When we touch a Van de Graaff generator, our hair may stand up if it is dry. This happens only if the strands of our hair do what?
Answer:
Repel each other.
Explanation:
Van de Graaff generator is a device that was invented in 1929, by an American physicist called Robert J. Van de Graaff.
A Van de Graaff generator refers to an electrostatic generator that typically involves the use of a moving belt to accumulate electric charge on a hollow globe that is made from metal placed on top of an insulated column and thereby, creating very high electric potentials i.e very high voltage-direct current (DC) electricity at low current levels.
Generally, when we touch a Van de Graaff generator, our hair may stand up if it is dry. This happens only if the strands of our hair repel each other because they are like charges i.e having the same potentials.

A student has two identical sheets of paper. He crumples one up into a small ball. If he drops the sheet of paper and the ball of paper off a building at the same time, which of the following statements describes the result?
A. The sheet of paper because it is more affected by gravity.
B. The ball of paper hits the ground first because it is more affected by gravity
C. The sheet of paper and the ball of paper hit the ground at the same time.
D. The ball of paper hits the ground first because it has less surface area.
Answer:
B
Explanation:
basically, because the ball "weighs" more now, it will hit the ground quicker. so technically gravity is more affective towards it. the piece of paper kind of floats it's way down. gravity isn't pushing on one force more, but because because the ball weighs more, it technically would be said so. hope this helps!
Answer:
the ball of paper, because it has less surface area.

What is the law of inertia? Give an example of inertia in action.
Answer:
The law of inertia is another name for Newton's first law. Newton's first law states that an object will not change its motion or direction unless a force acts on it. An object at rest will stay at rest and an object in motion will stay in motion if there isn't any force acting on them.
Example: When a car uses its brakes to stop, you sometimes feel like you are sliding forward. That is because the inertia keeps you moving forward, even though the car stopped.
Explanation:
Answer:
Law of inertia is sometimes called Newtons First law of motion.
Newtons first law of motion states that"A body will continue to its state of rest or motion unless external force acted upon it.
When an object is moving to the left and slowing down, what direction is the acceleration?
Answer:
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In Example D, the object is moving in the negative direction (i.e., has a negative velocity) and is speeding up.

The range of human hearing is 20 Hz – 20 000 Hz.
Calculate the longest and shortest wavelengths we can hear.
Explanation:
the velocity of sound in air is 330m/s
and v=fh, where h is wavelength f is frequency,
h=v/f.......(1)
longer wavelength
h=330/20,h=16.5m
shorter wavelength
h=330/20000,h=1.65x10-²m
The lesser frequency was used for finding the longer wavelength since wavelength is inversely proportional to frequency,
thus an increase in frequency brings a decrease in wavelength.
and shorter wavelengths are more high and intense
