A 1 kg puck sliding on a horizontal shuffleboard court is slowed to rest by 1 point
a frictional force of 3 N. What is the coefficient of kinetic friction between
the puck and the surface of the shuffleboard court? *
O A. 0.25
O B.0.5
O c.0.15
D. .31

Answers

Answer 1

Answer:

miu = 0.31

Explanation:

The friction force is defined as the product of the normal force by the coefficient of friction.

[tex]f=miu*N[/tex]

where:

f = friction force = 3 [N]

miu = friction coefficient

N = normal force [N]

The normal force on a horizontal surface can be calculated by means of the product of mass by gravity.

where:

m = mass = 1 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N=m*g\\N=1*9.81[/tex]

[tex]N= 9,81 [N][/tex]

Now replacing in the equation above, we can find the friction coefficient.

[tex]miu=3/9.81\\miu = 0.31[/tex]

30 POINTS!!!! If you increase the frequency, what happens to the velocity of the wave?

In answering this question, describe how you determined the velocity as well as the result you arrived at. Then, provide a scientific explanation for this result, based on your knowledge of waves.

Answers

Answer:

As frequency increases, wavelength decreases. Frequency and wavelength are inversely proportional. This basically means that when the wavelength is increased, the frequency decreases and vice versa.

Explanation:

A wave's velocity is independent of its intensity and equal to the product of its wavelength and frequency (number of vibrations per second) so, velocity remains constant if you increase the frequency.

What is Frequency?

Frequency is defined as the no of waves that are passing from the point in respect to a given time. Frequency can be measured in Hertz. Humans, whose capacity to hear is normal, can hear between the frequency of 20 Hertz to 20000 Hertz.

In mathematical form, the frequency is the factor of one divided by the time period. The number of cycles or vibrations a body in periodic motion makes in one unit of time.

Wavelength reduces as frequency rises. The relationship between frequency and wavelength is inverse. In essence, this means that the frequency reduces as the wavelength increases and vice versa.

Frequency ∝ 1 / Wavelength

Velocity = Frequency  ×  Wavelength

Thus, it remains constant.

A mover uses a pulley to lift a 2500N piano up to a second story balcony. The mover pauses to wipe sweat from his forehead while holding the rope tight in one hand. Since the piano is not moving at this time, what is the tension force in the rope while the piano is dangling still in the air?

Answers

Answer:

2500 N

Explanation:

Tension force may be defined as the force which is transmitted along a cable, rope, or through a string which is stretchable and is puled tight by the forces acting from the opposite sides. It is directed along the length of the string or the rope.

In the context, a pulley string holds a 2500 N piano that is used to lift it to second story balcony. When the piano is held stationary by the mover, the tension force acting on the rope is the weight force or the gravitational force that acts on the piano which is 2500 N. The tension force balances the the weight force of the piano when it is not moving.

it takes 5100 N of force to accelerate a ford mustang 3 m/s2 what is the mass of the car

Answers

Answer:

1700 kg

Explanation:

The mass of the ford mustang car be 1700 kg.

What is mass?

In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force.

The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).

Given parameters:

Force applied on the ford mustang car: F = 5100 N.

Acceleration of the ford mustang car: a = 3 m/s^2.

So, The mass of the ford mustang car be = force/acceleration

= 5100/3 kg.

= 1700 kg.

Hence, the mass of the ford mustang car be  1700 kg.

Answers

Answer:

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

Explanation:

According to Ohm's law, V = IR

V is the potential difference = 220volts

I is the current = 60 A

R is the resistance (Load)

Calculating the load R

R = V/I

R = 220/60

R = 3.67 ohms

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

A 50 Kg football player is standing still when he experiences an inelastic collision with a 150 Kg football player who is traveling at 10 m/s. What is the velocity of the player immediately after the collision?

Answers

Answer:

V = 7.5 m/s

Explanation:

Given that,

Mass of player 1, m₁ = 50 kg

Mass of player 2, m₂ = 150 kg

50 kg player stands still and 150 kg player is traveling at 10 m/s

We need to find the velocity of the player immediately after the collision. As the inelastic collision occurs. The linear momentum will remain conserved. After the collision, let they move with a constant velocity say V.So,

[tex]m_1u_1+m_2u_2=(m_1+m_2)V\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\=\dfrac{150\times 10}{(50+150)}\\\\=7.5\ m/s[/tex]

So, the velocity of the player immediately after the collision is 7.5 m/s.

A box at rest is in a state of equilibrium half way up on a ramp. The ramp has an incline of 42° . What is the force of static friction acting on the box if box has a gravitational force of 112.1 N ?

Answers

Answer:

Explanation:

The force of static friction acting on the box is the frictional force;

Frictional force Ff = Wsin theta (force acting along the ramp)

W is the gravitational force known as the weight

Ff = 112.1sin42°

Ff = 112.1(0.6691)

Ff = 75.00N

Hence he force of static friction acting on the box  if box has a gravitational force of 112.1 N id 75.00N

You want to push a 71-kg box up a 16° ramp. The coefficient of kinetic friction between the ramp and the box is 0.23. With what magnitude force parallel to the ramp should you push on the box so that it moves up the ramp at a constant speed?

Answers

Answer:

345.60N

Explanation:

The magnitude of the force parallel to the ramp that will push the box up the ramp are the frictional force(Ff) and the moving force Fm

Total force = Ff + Fm

Ff = ηR

Ff = ηmgcosθ

Fm = Wsinθ

Fm = mgsinθ

Total force = ηmgcosθ + mgsinθ

Total force = mg(ηcosθ + sinθ)

Given

mass m = 71kg

acceleration due to gravity g = 9.8m/s²

angle of inclination θ = 16°

coefficient of friction η = 0.23

Substitute into the formula;

Total force = 71(9.8)(0.23cos16 + sin16)

Total force = 695.8(0.2211+0.2756)

Total force = 695.8(0.4967)

Total force = 345.60N

Hence the magnitude force parallel to the ramp that you should push on the box so that it moves up the ramp at a constant speed is 345.60N
