A horizontal floor is the resting place for a 50 kg crate. The static friction coefficient between the floor and the crate is 0.75. Kinetic friction has a coefficient of 0.60. The minimum horizontal force required to start the crate moving is 367.5 N

To find the minimum horizontal force required to start the crate moving across the floor, we need to consider the static friction between the crate and the floor. The formula to calculate the maximum static friction is  Fs = μs × N

where Fs is the maximum static friction, μs is the coefficient of static friction, and N is the normal force.

The normal force N is equal to the weight of the crate, which is given by:

N = m × g

where m is the mass of the crate and g is the acceleration due to gravity.

Substituting the values, we have:

N = 50 kg × 9.8 m/s² = 490 N

Now we can calculate the maximum static friction:

Fs = 0.75 × 490 N = 367.5 N

Therefore, the minimum horizontal force required to start the crate moving is 367.5 N (magnitude only).

Among the given statements about friction: 1 - For a stationary 10 kg box on a horizontal floor with a coefficient of static friction μs=0.5, the force of static friction is 49 N. This statement is not necessarily true.

This statement is not necessarily true. The force of static friction can vary depending on the applied force and the maximum force of static friction can be calculated using the equation F_static = μ_s * N, where μ_s is the coefficient of static friction and N is the normal force. In this case, the force of static friction would be

F_static = 0.5 * 10 kg * 9.8 m/s^2

= 49 N.

For an object sliding on a surface, the coefficient of friction only depends upon the object and surface materials.

This statement is generally true. The coefficient of friction is a property that depends on the nature of the two surfaces in contact and the materials involved.

The unit of the coefficient of static friction is Newtons.

This statement is not true. The coefficient of static friction is a dimensionless quantity and does not have units. It represents the ratio of the force of static friction to the normal force.

The answer to the question is:

77.0 dB

When the distance from a point source of sound is doubled, the intensity level decreases by 6 dB. This decrease in intensity level with increasing distance is due to the spreading of sound waves over a larger area. According to the inverse square law, the intensity of sound is inversely proportional to the square of the distance from the source.

In this case, the distance is doubled from 2.00 m to 4.00 m. Since the distance is doubled, the intensity level will decrease by 6 dB. Therefore, we subtract 6 dB from the initial intensity level of 80.0 dB.

80.0 dB - 6 dB = 74.0 dB

So, the intensity level at a distance of 4.00 m from the source will be 74.0 dB.

Explanation:

correct edge 2023

Answer:

The value is \(T = 122036.2 \ N\)

Explanation:

From the question we are told that

     The mass of the car is  \(m = 6526 \ kg\)

      The acceleration  is  \(a= 8.9 \ m/s^2\)

Generally the net force applied on the rope is mathematically represented as

          \(F_{net} = T - W\)

Here W is the weight of the car which is evaluated as

         \(W = m * g\)

=>      \(W = 6526 * 9.8\)

=>       \(W = 63954.8 \ N\)

Generally the net force can also be mathematically represented as

       \(F = m * a\)

So

        \(m * a = T - 63954.8\)

=>     \(6526 * 8.9 = T - 63954.8\)

=>      \(T = 122036.2 \ N\)

Based on the assumptions, the total energy stored in the capacitors can be calculated using the formula E=1/2CV^2, where C is the capacitance and V is the voltage across each capacitor.

To relate the total energy stored in the capacitors for each configuration to the time the light bulb remains lit after each circuit is closed, the following assumptions must be made:

The capacitors are assumed to be ideal, meaning they have no internal resistance, leakage, or other losses.

The resistors and light bulb are also assumed to be ideal, meaning they have no inductance, capacitance, or other parasitic effects.

The circuits are assumed to be in steady-state before the switch is closed, meaning the voltages and currents have settled to their final values.

The switch is assumed to be ideal, meaning it has no resistance or other losses when closed.

The wiring between the components is assumed to have negligible resistance and capacitance, so that it does not significantly affect the circuit behavior.

The human vocal apparatus is an incredibly complex and efficient machine. The production of speech sounds begins with the diaphragm, a large, flat muscle located at the bottom of the lungs. When the diaphragm contracts, it increases the volume of the thoracic cavity and forces air into the lungs. The air then passes through the larynx, or voice box, which contains the vocal cords. The vocal cords are two thin bands of tissue that vibrate when air passes through them. The pitch of the resulting sound is determined by the tension of the vocal cords.

The sound of the vibrating vocal cords is then amplified by the resonating cavities of the head and mouth. The shape of the mouth cavity plays a significant role in the production of speech sounds. For example, the placement of the tongue, teeth, and lips all contribute to the creation of different vowel sounds. The hard and soft palate, along with the tongue, also help to create different consonant sounds.

Answer:

Explanation:

Using the conservation of law of momentum which states that the sum of momentum of bodies before collision is equal to the sum of the bodies after collision.

Momentum = Mass (M) * Velocity(V)

BEFORE COLLISION

Momentum of 0.25kg body moving at 1.0m/s = 0.25*1 = 0.25kgm/s

Momentum of 0.15kg body moving at 0.0m/s(body at rest) = 0kgm/s

AFTER COLLISION

Momentum of 0.25kg body moving at x m/s = 0.25* x= 0.25x kgm/s

x is the final velocity of the 0.25kg ball

Momentum of 0.15kg body moving at 0.75m/s(body at rest) =

0.15 * 0.75kgm/s = 0.1125 kgm/s

Using the law of conservation of momentum;

0.25+0 = 0.25x + 0.1125

0.25x = 0.25-0.1125

0.25x = 0.1375

x = 0.1375/0.25

x = 0.55m/s

Since the 0.15 kg ball moves off to the right after collision, the 0.25 kg ball will move at 0.55 m/s towards the right

Therbligs are basic physical elements of motion used in methods time measurement exercises to analyze and measure work processes. They represent the smallest unit of time and the full range of motions required to complete a job.

Therbligs were introduced by Frank B. Gilbreth, an industrial engineer, as a means to analyze and improve work processes. They are used in methods time measurement exercises to break down a task or job into its fundamental motions. Each therblig represents a specific basic physical element of motion, such as grasp, position, release, search, transport, and so on. These elements can be combined in different sequences to represent the full range of motions required to complete a job. Therbligs are used to measure the time required to perform each individual motion, and by summing up the times for all therbligs involved, the total time to complete a job can be determined. By analyzing the therbligs involved in a task, engineers can identify inefficiencies, eliminate unnecessary motions, and streamline work processes to increase productivity and reduce fatigue or strain on workers.

Therefore, therbligs serve as a standardized method for measuring and evaluating work processes, allowing for improvements in efficiency and productivity. They represent both the smallest unit of time used in methods time measurement exercises (individual motions) and the largest unit of time (the full range of motions required to complete a job).

Approximately 33.1 degrees is the maximum angle of displacement of the swinging pendulum.

The maximum angle of displacement of the swinging pendulum can be determined using the principle of conservation of energy. When the student kicks the bob, the pendulum gains kinetic energy, which is then converted into potential energy as it swings upwards. At the highest point of its swing, all of the kinetic energy is converted into potential energy, and the pendulum comes to a momentary stop before swinging back down.

The potential energy of the pendulum at its highest point can be calculated as the product of its mass, acceleration due to gravity (9.81 m/s²), and the height it rises to. The height can be determined using the initial horizontal velocity imparted by the kick, which can be calculated using the force applied and the distance over which it acts. Assuming the pendulum swings upwards in a straight line, the height can be calculated using basic trigonometry.

The maximum angle of displacement can then be determined using the equation for the potential energy of a pendulum, which is proportional to the square of the sine of the angle of displacement from the equilibrium position. Solving for the angle, we get:

θ = arcsin(√(2gh)/l)

where h is the height the pendulum rises to, l is the length of the pendulum, and g is the acceleration due to gravity.

Substituting in the values given, we get:

h = (30 N)(sin(θ))(1 m)/(5.0 kg)(9.81 m/s²)
h ≈ 0.613 m

θ = arcsin(√(2(9.81 m/s²)(0.613 m))/l)

Assuming a standard length of 1.0 m for the pendulum, we get:

θ ≈ 0.577 radians or 33.1 degrees

Therefore, the maximum angle of displacement of the swinging pendulum is approximately 33.1 degrees.
