According to Newton's second law equation, what is the relationship between net force applied and the acceleration of the object

Acceleration is inversely proportional to the net force

if acceleration goes up forces goes down

if acceleration goes down mass goes down

Acceleration is directly proportional to the net force

Answers

Answer:

Acceleration is directly proportional to the net force

Explanation:

The net force acting on an object is given by :

F = ma

Where

m is mass

and

a is acceleration

It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).

An experiment is designed to test what color of light will activate a photoelectric cell the best. The photocell is set in a circuit that "clicks" in response to current. The faster the current, the more clicks per minute. In this experiment, the number of clicks in one minute is recorded for each color of light shining on the photocell. To change the color of light, a different color of cellophane is placed over the same flashlight and the flashlight is then located a specific distance from the photocell.

Which of the following was not kept constant?


the color of the light after it has passed through the cellophane
the source of the original light
the distance of the light from the photocell

If you climb to the top of Mt. Everest, you will be 8850 m (about 5.50 mi) above sea level.
What is the acceleration due to gravity at this altitude?

Answers

Answer:

9.773m/s2

Explanation:

Given,

h=8848m

The value of sea level is 9.08m/s2

So,

Let g′ be the acceleration due to the gravity on the Mount Everest.

g′=g(1−h2h)

=9.8(1−640000017696)

=9.8(1−0.00276)

9.8×0.99724

=9.773m/s2

Thus, the acceleration due to gravity on the top of Mount Everest is =9.773m/s2

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N What is the acceleration of his fall?

Answers

H E R E I S T H E A N S W E R

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall  7.5 m/sec².

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To find the acceleration,

   F = mg

   F = 80.(10)

   F = 800 N

   air resistance = 200 N

   Net force = F - air resistance

                = 800 - 200

                =  600 N

   600 = mass . acceleration

   600 = 80 . acceleration

   acceleration = 7.5 m/sec²

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall  7.5 m/sec².

DEFINE KINETIC ENERGY AND PATAINTIA ENERGY please​

Answers

Answer:

1. Kinetic energy is the energy possessed by a body due to its motion. Potential energy is the energy possessed by a body due to its position or state. Kinetic energy can be transferred from one object to another, in case of collisions. Potential energy cannot be transferred. Thus, the potential energy is stored in the object due to its position, whereas the kinetic energy is possessed by an object due to motion.

Eg: A ball kept on the edge of the table possesses potential energy due to its height, whereas a ball falling down from the table will possess kinetic energy due to its motion.

2. The formula for Kinetic energy is as below: This means that kinetic energy is directly proportional to mass as well as velocity. But it is proportional to 1 unit of mass and a square of velocity. Hence, velocity has a greater effect on kinetic energy.…show more content…

3. The equation for kinetic energy is: .

Let’s calculate the kinetic energy of a 40 kg object traveling 15 m/s.

Solution: mass= 40kg, velocity= 15 m/s, so putting these numbers into the kinetic energy equation,

Now, let’s calculate the kinetic energy of a 40 kg object traveling 30 m/s.

Solution: mass= 40kg, velocity= 30 m/s, so putting these numbers into the kinetic energy equation, Thus, when we double the velocity of an object, its kinetic energy increases by four times. Hence the velocity of an object has more impact on kinetic energy than the mass of an object.

12) Two-point charges each have a value of 3.0 C and 5.0 C and are separated by a distance of 6.0 m. What is the electric field at a point midway between the two charges?

Answers

Answer:

The electric field at a point midway between the two charges is 2 x 10⁹ N/C.

Explanation:

Given;

first point charge, Q₁ = 3.0 C

second point charge, Q₂ = 5.0 C

distance between the two point charges, R = 6.0 m

The mid-point between the two charges, r = R/2 = 3.0 m

3.0 C <-------------------->3.0m<----------------------->5.0 C

The forces are acting in opposite direction, the electric field strength of each charge is calculated as;

[tex]E_1 = \frac{kQ_1}{r^2} (-\bar x)\\\\E_1 = \frac{9\times 10^9 \times 3}{3^2}(-\bar x)[/tex]

[tex]E_2 = \frac{kQ_1}{r^2} (+\bar x)\\\\E_2 = \frac{9\times 10^9 \times 5}{3^2} (+\bar x)\\\\[/tex]

The net electric field is calculated as;

[tex]E_{net} = \frac{9\times 10^9 \times 5}{3^2} \ - \ \frac{9\times 10^9 \times 3}{3^2}\\\\E_{net} = \frac{9\times 10^9 }{3^2} (5-3)\\\\E_{net} = 2 \times 10^9 \ N/C[/tex]

Therefore, the electric field at a point midway between the two charges is 2 x 10⁹ N/C.

Consider two equally charged objects separated by a short distance.  According to Coulomb’s Law, how does doubling the charge on one object affect the electric force present between two charged objects

Question 4 options:
A. results in one-half of the original electric force
B. results in one-fourth of the original electric force
C. increases the electric force by a factor of four
D. double force by a factor of four

Answers

Answer:

Coulomb's Law states

F = K Q1 * Q2 / R^2      where K is the force constant

F2 / F1 = 2 Q1 * Q2 / (Q1 * Q2) = 2   where one of the charges is doubled

So the force will be doubled  (D looks rather vague but it cannot be the other three)

How do you know that Earth is affected by the gravitational pull of the sun ? Explain how you would be affected if you were able to safely move farther and farther away from Earth . Support your ideas

Answers

Answer:

The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Explanation: Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. I am so sorry if I get this wrong, I'm in 5th grade! ♥

The Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

The Earth is continuously orbiting around the Sun, that is why we are experiencing the day and night everyday. And this orbiting is caused by the gravitational full by Sun on Earth, which is given as,

[tex]F = \dfrac{G \times M \times M'}{R^{2}}[/tex]

Here, G is the universal gravitational constant, M is the mass of Earth and M' is the mass of Sun. And R is the distance between the Earth and Sun.

If we suppose to move farther and farther away from the Earth then the strength of gravitational pull by Earth will decrease with the increasing distance. Because the gravitational pull is inversely proportional to square of distance.

Thus, we can conclude that the Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.
