Which Is The Correct Equation For The Force Applied By A Spring?

Answers

Answer 1
B, F= -kx.


The proportional constant k is called the spring constant. It is a measure of the spring's stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.

An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second

Answers

Answer:

The resultant momentum is 12.97 kg.m/s. Choice: c

Explanation:

Momentum

The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".

As a vector, it can be expressed by its rectangular components:

[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]

The magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]

The object described has an x-component of:

px=8.5 Kg.m/s

And a y-component of:

py=9.8 Kg.m/s

Thus, the magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]

[tex]\mid \mid \vec p \mid \mid =12.97[/tex]

The resultant momentum is 12.97 kg.m/s. Choice: c

the stolen valor act

Answers

Answer:

The Stolen Valor Act of 2005, signed into law by President George W. Bush on December 20, 2006, was a U.S. law that broadened the provisions of previous U.S. law addressing the unauthorized wear, manufacture, or sale of any military decorations and medals. The law made it a federal misdemeanor to falsely represent oneself as having received any U.S. military decoration or medal. If convicted, defendants might have been imprisoned for up to six months, unless the decoration lied about is the Medal of Honor, in which case imprisonment could have been up to one year. In United States v. Alvarez, the U.S. Supreme Court ruled that the Stolen Valor Act was an unconstitutional abridgment of the freedom of speech under the First Amendment, striking down the law in a 6 to 3 decision.

You are in a plane, and hit a bird as your flying, how can this impact produce a large impulse, despite the plane being much bigger

Answers

It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.

1. Spring force is proportional to stretch distance, F=kd. Do you expect doubling the stretch distance double the force?
Yes
No

Answers

Answer:

Yes

Explanation:

The spring force is given as:

          F  = kd

F is the spring force

K is the spring constant

d is the magnitude of the stretch

 Since k is a constant, therefore, doubling the stretch distance will double the force.

Both stretch distance and force applied can be said to be directly proportional to one another.

A.) A 5.0 kg mass moving at 2.0 m/s

B.) A 8.0 kg mass moving at 9.0 m/s

C.) A 6.0 kg mass moving at 10. m/s

D.) A 15 kg mass moving at 2.0 m/s

Answers

Answer:

D.) A 15 kg mass moving at 2.0 m/s

Explanation:

The inertia of an object is most directly related to its mass and not the magnitude of the velocity.

So, the higher the mass of an object, the more its inertia.

According to Newton's first law of motion "an object will remain in its state of rest or of constant motion unless it is acted upon by an external force".

Inertia is the tendency of a body to remain in a state of rest either by virtue of its static position of constant motion. The larger the mass, the more this tendency. An object with a large mass will take more force to bring it from rest or change its motion.

Using the picture above, which ball has the greatest potential energy?

Answers

Ball 4 because the higher the elevation is the greater the potential energy it has

Ball 1 has the greatest amount of potential energy inside it because it has the maximum height among all the balls shown in the graph.

What is Potential energy?

Potential energy is the stored energy which depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched due to external force.

Potential energy is not affected by the environment outside of the object or its system, such as the air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.

The potential energy of an object depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity and h is the height in meters.

The object 1 has maximum height hence, it has greatest potential energy.

David is running laps around his apartment complex. Each lap is 1000 m. Starting from his front door and ending at his front door, David completes 4 laps of his complex. What is David's displacement?

Answers

Answer:

Displacement = 4000 m

Explanation:

Given that,

Each lap is 1000 m.

David completes 4 laps of his complex

We need to find David's displacement. In n laps, the net displacement is n time of distance covered.

Displacement = 4 × 1000

= 4000 m

Hence, Davis's displacement is 4000 m.

where does reduction occur in an electrolytic cell

d. wire

Answers

Answer:

The answer is actually a. Cathode

Explanation:

Just took the quiz

In an electrolytic cell, the reduction occurs at the cathode. So, the correct option is a.

What is meant by reduction ?

Reduction is defined as the process through which a reactant gain electrons during a chemical reaction.

Here,

An electrolytic cell is an equipment that uses electric current to drive a redox reaction.

Redox reactions are the type of reaction that involves the transfer of electrons between the reactants. That means, in redox reactions, both oxidation and reduction occurs. The reactant that gains the electrons is said to be reduced and the one that losses the electrons is said to be oxidized.

In an electrolytic cell, cathode is the positively charged electrode. So, electrons are attracted towards it, and as a result, the cathode gets reduced.

Hence,

In an electrolytic cell, the reduction occurs at the cathode.
