Answer:

False because each force might have a different about and a different direction.

What is force?

A force in physics is an effect that has the power to alter an object's motion. 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.

The vector sum of all the forces equals the net force. In other words, the net force is the sum of all forces, it is obtained by combining all forces as vectors. The net force is the sum of the force vectors A + B + C for the situation of the three forces on the force board.

Work done due to force is given as,

Work done, W = F.S cosФ

Where F is force a vector quantity, S is displacement and Ф is angle between them.

When forces are exerted in different direction than net force is calculated using vector sum.

A girl is bouncing on a trampoline where is her gravitational potential energy a maximum and where is her kinetic energy maximum

Answers

Answer:

When you jump down, your kinetic is converted to potential energy of the stretched trampoline. The trampoline's potential energy is converted into kinetic energy, which is transferred to you, making you bounce up. At the top of your jump, all your kinetic energy has been converted into potential energy. Right before you hit the trampoline, all of your potential energy has  been converted back into kinetic energy. As you jump up and down your kinetic energy increases and decrease.

A flowerpot that has a mass of 1.5 kg is sitting on a windowsill 30 meters from the ground. Is the energy of the flowerpot potential of kinetic?

How much energy does the flowerpot have?

Answers

Answer:

Potential energy

441 joules

Explanation:

The flower pot is not moving so it does not have kinetic energy. Anything that is still and a distance from the ground does have potential energy.

Amount of energy: p=mggh

p=1.5(9.8)(30)=441 joules

The flower pot's energy is measured in potential energy since it is remaining stationary and the energy is stored,  the flowerpot is not moving about so it is not kinetic energy.

The formula for potential energy is:

GPE = mgh

The m stands more mass, the g stands for gravitational energy (9.8m/s^2) and the h stands for height.

Our values for the following terms are:

M = 1.5kg

G = 9.8m/s^2

H = 30 meters

Now, we can plug it into our formula to solve for the amount of potential energy.

GPE = 1.5(9.8)(30)

First, let's multiply the gravitational energy and the height.

30 x 9.8 = 294

Then, multiply the mass by the result.

1.5 x 294 = 441

Therefore, the potential energy of the flowerpot is 441J.

The structure of a main sequence star like our sun can hold for a long time because

A. Gravitation fore is counterbalanced by thermal expansion forces

B. The immense volume of matter

C. The rotational force

Answers

Answer: B

The immense volume of matter 

Explanation:

Stars are formed by cloud and dust, draw together by gravity.

But the longevity of a main sequence star lives depends on how massive it is. An enormous massive star burns faster due to its enormous material it contains and higher core temperatures caused by greater gravitational forces. While a less massive star will burn slowly and stick around the sun for a very long period. The structure of a main sequence star like our sun can therefore hold for a long time because of the immense volume of matter of star.

A 100 kg bag of sand has a weight on 100 N. When dropped its acceleration is what?

Answers

Answer:

The acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

Explanation:

We have,

Mass of a bag of sand is 100 kg

Weight of the bag of sand is 100 N

It is required to find the acceleration of the bag when it is dropped. The weight of an object is given by :

[tex]F =ma[/tex]

When it is dropped, a = g

[tex]g=\dfrac{F}{m}\\\\g=\dfrac{100}{100}\\\\g=1\ m/s^2[/tex]

So, the acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

A TV draws 0.867 A of current when connected to a 122 V outlet. It’s resistance is 140.71.
A.)How many electrons pass through the TV per minute?
B.)How much electrical energy does the TV convert to other forms of energy
per minute?

Answers

Answer:

Explanation:

current measures charge flowing per second .

A current of .867 A means charge of .867 coulomb is flowing per second

charge flowing per minute = .867 x 60

= 52.02 coulomb

one electrons carries a charge of 1.6 x 10⁻¹⁹ Coulomb

So no of charge flowing per minute

= 52.02 / 1.6 x 10⁻¹⁹

= 32.5 x 10¹⁹ .

B )

electrical energy consumed per minute

= V X I X t , V is volt , I is current and t is time .

= 122 x .867 x 60

= 6346.44 J .

Dinesh wants to launch a package over the garden wall to his friend on the other side. His plan is to set up a see-saw, put the package on one end and jump on the other end. Dinesh determines that he will land on the board with a force of 1,127 newtons, and the package weighs 322 newtons. The board he is going to use for the see-saw is 9 meters long. How close to the end of the board should Dinesh put the fulcrum?

Answers

Answer:

Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

Explanation:

Let the fulcrum be x meters from Dinesh's end.

The sum of clockwise moment must balance the sum of anti-clockwise moment.

Taking a moment about the fulcrum

(Force exerted by Dinesh) × (Distance of Dinesh from the fulcrum) = (Weight of the package) × (Distance of the package from the fulcrum)

Force exerted by Dinesh = 1127 N

Distance of Dinesh from the fulcrum = x m

Weight of the package = 322 N

Distance of the package from the fulcrum = (9 - x) m

1127 × x = 322 (9 - x)

1127x = 2,898 - 322x

1127x + 322x = 2,898

1449x = 2898

x = (2898/1449) = 2 m

Hence, Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

Hope this Helps!!!

is friction and pushing similar ????

Answers

Answer:

Yes, they are.

Explanation:

Answer:

No.

Explanation:

Pushing is the act of moving an object "forward" or towards the desired location.

Friction generally occurs when two surfaces (in this case, the ground and the object you are pushing) rub against each other. Gravity & the heaviness of the object will act as the counter to the force applied to push the object. Friction is the object trying to stay still, while pushing is trying to move the object.
