Answers

Answer 1

Answer:

1. The elastic potential energy is 0.0176 Joules

2. The kinetic energy of the pinball the instant it leaves the spring is 0.0176 Joules

3. The speed of the pinball the instant it leaves the spring is approximately 2.42212 m/s

4. The height of the part where the pinball is located on the machine above the ground is approximately 0.213 meters

Explanation:

The spring constant of the pinball machine's plunger, k = 22 N/m

The amount by which the pinball machine's plunger is compressed, x = 0.04 m

The mass of the pinball ball, m = 0.006 kg

1. The elastic potential energy, P.E. = 1/2·k·x²

By substitution, we get;

P.E. = 1/2 × 22 N/m × (0.04 m)² = 0.0176 J

The elastic potential energy, P.E. = 0.0176 J

2. At the instant the pinball leaves the spring, the plunger and therefore the force of the plunger no longer acts on the pinball

Since there are no external forces acting on the pinball to increase the speed of the pinball after it leaves the spring, the velocity reached is its maximum velocity, and therefore, the kinetic energy, K.E. is the maximum kinetic energy which by the conservation of energy, is equal to the initial potential energy

Therefore;

K.E. = P.E. = 0.0176 J

The kinetic energy of the pinball the instant it leaves the spring, K.E.= 0.0176 J

3. The kinetic energy, K.E., is given by the following formula;

K.E. = 1/2·m·v²

Where;

v = The speed or velocity of the object having kinetic energy K.E.

Therefore, from K.E. = 0.0176 J, and by plugging in the values of the variables, we have;

K.E. = 0.0176 J = 1/2 × 0.006 kg × v²

v² = 0.0176 J/(1/2 × 0.006 kg) = 88/15 m²/s²

v = √(88/15 m²/s²) ≈ (2·√330)/15 m/s ≈ 2.42212 m/s

The speed of the pinball the instant it leaves the spring, v ≈ 2.42212 m/s

4. The height of the pinball is given by the following kinematic equation of motion;

[tex]v_h[/tex]² = u² - 2·g·h

Where;

[tex]v_h[/tex] = The velocity of the pinball at the given height = 1.3 m/s

u = v ≈ 2.42212 m/s (The initial velocity of the pinball as it the spring)

g = The acceleration due to gravity ≈ 9.8 m/s²

h = The height of the pinball above the ground

We get;

[tex]v_h[/tex]² = 1.3² = 2.42212² - 2 × 9.8 × h

∴  h = (2.42212² - 1.3²)/(2 × 9.8) ≈ 0.213

The height of the part where the pinball is located on the machine above the ground, h ≈ 0.213 m

!THANK YOU!

Answers

Answer:

No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.

what is acceleration​

Answers

Answer: acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Explanation:

Are acceleration and force proportional or inversely proportional values?

Answers

Answer:

Yes, acceleration and force are directly proportional to each other.

Explanation:

The force acting on an object is given by :

F = ma

Where

m is mass

a is acceleration

It can be clear from the above formula that the acceleration and the force are directly proportional to each other.

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass. How fast are they traveling? How would you find your answer?

Answers

Answer:

They traveling at  along the direction of 55 kg kid.

Step-by-step explanation:

Conservation of momentum-

Momentum of a system is constant if there are no external forces acting on the system.

As they crash into each other and hold onto each other so that they move as one mass and no other force is acting on them, so conservation of momentum can be applied here.

The final direction of velocity will be opposite to the assumed direction of the mass of 40 kg.

This is a conservation of momentum problem. The equation relevant here is

[tex]\[m_1v_1+m_2v_2=\left ( m_1+m_2 \right )v_f\][/tex]

where m is the mass and v is the velocity. Because Amy and Jenny move as one mass after crashing (or colliding) with each other, this is an inelastic collision. What we to find is the final velocity, [tex]v_f[/tex], of both Amy and Jenny as a single body.

[tex]v_f=\frac{m_1v_1+m_2v_2}{\left ( m_1+m_2 \right )} = \frac{(55)(3)+(40)(5)}{(55+40)} = \text{3.84 m/s}.[/tex]

A sharpening wheel is traveling at 5 rad/s, it slows down to rest in 30 seconds while sharpening an axe. What is its angular acceleration?

A proton moves perpendicularly to a magnetic field that has a magnitude of 4.20 x 10-2 T. What is the speed of the particle if the magnitude of the magnetic force on it is 2.40 x 10-14 N?​

Answers

Answer:

V=3.57 × 10^6 m/s

hope it is helpful..

The speed of the proton in the magnetic field is 3.57×10⁶ m/s.

To determine the speed of the proton, we need to know about the magnetic force experienced by a charged particle in a magnetic field.

What is the magnetic force on a charge particle in a magnetic field?From lorentz law, the magnetic force on a charge particle is given as

               F=q×v×B

  where, q= charge of the particle

              v= speed of the particle

              B= magnetic field

What will be the speed of the charge particle, proton, if the magnetic field and force are given?Magnetic force(F)= q×v×B

       v=F/(q×B)

Here, B= 4.20×10⁻²T

                  F=2.40×10⁻¹⁴N

                  q= 1.6×10⁻¹⁹C

       Then, v= 2.40×10⁻¹⁴/ ( 4.20×10⁻²× 1.6×10⁻¹⁹)

                   = 3.57×10⁶ m/s.

Thus, we can conclude that the speed of the proton in the magnetic field is 3.57×10⁶ m/s.

A car weighs 11000 N on Earth. What is its mass?

A) 300 kg
B) 1122 kg
C) 0 kg
D) 107,800 kg

Answers

Weight is the measurement of the force of gravity, and it is mathematically defined as the mass of an object multiplied by gravitational acceleration: W = mg. On Earth, g is about 9.8 m/s². Rearranging the equation to find mass, m = W/g. Given our weight of 11000 N, the mass of the car would thus be m = 11000 N/9.8 m/s² = 1122 kg. So, the correct answer choice here would be B.

How far does a sound wave travel in 3 seconds if the air temperature is 30 degrees
Celsius?

a) 114.33 m
b) 1047 m
c) 1029 m
d) 116.33 m

Answers

Answer:

B

Explanation:

v=349m/s

d=vt

d=349*3

d=1047m

WHY 349??

Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.

Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

As a cold air mass advances on a warm air mass, what usually comes before it?​

Answers

Answer: A cold front occurs when a cold air mass advances into a region occupied by a warm air mass. If the boundary between the cold and warm air masses doesn't move, it is called a stationary front.

Explanation: Two types of occluded front exist: the warm-type and the cold-type. They’re distinguished by the relative temperatures of the air mass ahead of the occlusion – in other words, the air mass ahead of the original warm front – and the air mass behind the cold front. If the air behind the cold front is colder than the air ahead of the occlusion, it shoves beneath that air (because it’s denser) to form a cold-type occluded front. If the air behind the cold front is warmer than the air ahead, it rides over it to form a warm-type occluded front – which appears to be the more common case. In either situation, the lighter warm air representing the air mass originally between the warm and cold fronts sits above the boundary between the two cooler air masses.

What is nuclear reaction?

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.
