The coefficient of friction in the hall is 0.038

Explanation:

Given;

mass of the Parker, m = 73.2 kg

applied force on the parker, F = 123 N

frictional force, Fs = 27.4 N

the coefficient of friction in the hall = ?

frictional force is given by;

Fs = μN

Where;

μ is the coefficient of friction

N is normal reaction = mg

Fs = μmg

μ = Fs / mg

μ = (27.4) / (73.2 x 9.8)

μ = 0.038

Therefore, the coefficient of friction in the hall is 0.038

Sure! Here are the steps for calculating the velocity and distance traveled by the car after 50 seconds :

Step 1: Calculate the velocity using the equation:

\(v = u + at\)

where:

- \(v\) is the final velocity

- \(u\) is the initial velocity (0 m/s, as the car starts from rest)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(v = 0 + (3 \, \text{m/s²}) \times (50 \, \text{s})\)

Step 2: Calculate the distance traveled using the equation:

\(s = ut + \frac{1}{2}at^2\)

where:

- \(s\) is the distance traveled

- \(u\) is the initial velocity (0 m/s)

- \(a\) is the acceleration (3 m/s²)

- \(t\) is the time (50 seconds)

Substituting the values into the equation:

\(s = 0 \times (50 \, \text{s}) + \frac{1}{2} \times (3 \, \text{m/s²}) \times (50 \, \text{s})^2\)

Now, let's simplify these equations:

\(v = 3 \times 50\)

\(s = \frac{1}{2} \times 3 \times 50^2\)

Calculating the results:

\(v = 150\) m/s

\(s = 3750\) meters

Therefore, after 50 seconds, the car will have a velocity of 150 m/s and would have traveled a distance of 3750 meters.

Electromagnetic radiation is a type of energy that travels through space in the form of waves. The different types of electromagnetic radiation are classified based on their frequency and wavelength. The frequency of electromagnetic radiation refers to the number of waves that pass a given point in a second, and it is measured in Hertz (Hz).

The types of electromagnetic radiation with the shortest frequency are gamma rays. Gamma rays have the highest frequency, ranging from 10^19 Hz to more than 10^24 Hz. They have the shortest wavelength and the highest energy among all electromagnetic radiation. Gamma rays are produced by the decay of atomic nuclei and in nuclear reactions. They are also produced by astronomical objects such as pulsars, supernovas, and black holes.

Gamma rays are extremely dangerous and can be harmful to living organisms. They can ionize atoms and molecules, which can damage DNA and cause mutations, cancer, and other health problems. Therefore, it is important to shield ourselves from gamma rays by using protective equipment and following safety protocols when working with sources of ionizing radiation.

Given function is \(\(\ f(x)=\frac{x-1}{x-3}\)\)  Let's find inverse of function first. 

\(\(y=\frac{x-1}{x-3}\)\)  Switch y with \(\(x=\frac{y-1}{y-3}\)\)  Solve for y.

Multiply both sides by (y-3) on both sides of the equation  \(\(x(y-3)=y-1\)\)  Distribute \(x\(xy-3x=y-1\)\)

Add 3x to both sides of the equation \(\(xy=y+3x-1\)\)

Factor out y on the right side of the equation  \(\(y(x-1)=3x-1\)\)

Divide both sides of the equation by   \((x-1)\(\frac{y(x-1)}{(x-1)}=\frac{3x-1}{x-1}\)\(y=\frac{3x-1}{x-1}\)\)

Thus, \(\(\ f^{-1}(x)=\frac{3x-1}{x-1}\)\)

Find the value of   \(\(\ f^{-1}(8)\). \( f^{-1}(x)=\frac{3x-1}{x-1}\)\( f^{-1}(8)=\frac{3(8)-1}{8-1}=\frac{23}{7}\)\)

Answer:

Difference = 1.83 hours

Explanation:

Let the two trips be A and B respectively.

Given the following data;

Distance A = 2000 miles

Speed A = 400 miles

Distance B = 2000 miles

Speed B = 480 miles per hour

To find the time spent;

a. For trip A.

Time A = distance A/speed A

Time A = 2000/400

Time A = 5 hours

b. For trip B.

Time B = distance B/speed B

Time B = 2000/480

Time B = 4.17 hours

Next, we would find the difference between the two trips.

Difference = Time A - Time B

Difference = 5 - 4.17

Difference = 1.83 hours

Therefore, the return trip was much quicker by 1.83 hours.

The return trip of the airplane will be quicker by 1.84 hours

It is given that

Distance covered by the plane D= 2000 miles

The average speed of the plane

 \(V_1=400\ \frac{Miles }{hour }\)

The Return Average speed of the plane

\(V_2= 480\ \frac{Miles}{hour}\)

Now we will first find the time taken by the airplane during the first visit.

\(V_1=\dfrac{Distance }{Time }\)

\(Time = \dfrac{Distance }{V_1}\)

Now by putting the values in the formula

\(T_1=\dfrac{2000}{400} =5\ hours\)

Now for the return trip time taken by the plane

\(T_2=\dfrac{Distance }{V_2}\)

\(T_2= \dfrac{2000}{480}\)

\(T_2= 4.16\ hours\)

Now the difference between the time will be

\(=T_1-T_2=5-4.16=0.86=1.84 \ Hours\)

Thus the return trip of the airplane will be quicker by 1.84 hours

Considering air resistance, the object to hit the ground first will be the iron ball.

This is because the iron ball has a greater mass and density compared to the wooden ball, allowing it to overcome air resistance more effectively and fall at a faster rate.The iron ball and the wooden ball will experience air resistance as they fall from the tower. The iron ball, being denser than the wooden ball, will experience less air resistance and therefore accelerate faster towards the ground. Therefore, the iron ball will hit the ground first.

The speed of the platform so that the person detects a beat frequency of 1.00 Hz is 5.286m/s.

The speaker moving towards the wall is emitting the sound of frequency of 115Hz and the platform right next to the speaker is detecting the sound reflected by the wall and emitted by the speaker.

Now, to find the speed of the platform so that the person here the beta frequency pf 1.00Hz, we will use the relation,

F = (c+v/c-v)f

c = Speed of waves in the medium

u = Speed of the receiver relative to the medium

v = Speed of the source relative to the medium

f = emitted frequency

Our values are given,

Beat frequency = 7Hz

Reflective Doppler frequency = 225+7=232Hz

Putting values,

232 =  (c+v/c-v)225

Answer:

The answer is D. moving at a constant rate.
Explanation:
I've had this question before.

In the position-time graph, the horizontal line segment indicates that the object is not moving and is at rest. Therefore, option (B) is correct.

The position vs time graph on which the instantaneous position of a particle is plotted on the y-axis and the time is plotted on the x-axis is called the Position-Time graph.

In the position vs time graph always take an independent variable on the x-axis and dependent variables must be plotted on the y-axis. Through mathematical function, the dependent variable will be dependent on the independent variable.

In the case of the Kinematic equation of uniform acceleration, the position can be defined as a dependent variable and time will be the fundamental independent variable.

The case of the horizontal line in the position vs. time graph indicates that the position of the object is not changing with time so it is at rest.

The spacecraft must travel at a constant velocity that allows it to cover the distance to the star in 3.5 years, as measured by travelers on the spacecraft.

To calculate this velocity, we need to know the distance to the star and the time it takes to reach it as measured by an observer on Earth. Then, we can use the time dilation formula from special relativity to calculate the velocity needed for the spacecraft to travel the same distance in 3.5 years, as measured by the travelers on board.

Without knowing the specific star, distance, and observer on Earth, we cannot provide an exact answer. However, we can say that the velocity required would likely be a significant fraction of the speed of light, given the relatively short travel time of 3.5 years.
