The term that best describes how many waves that pass? It's frequency because how many waves are passed by a given point or time is called the waves frequency. I hope this helped you out on your assignment.

The term frequency (D) best describes the number of waves that pass a point in one second and is measured in hertz (Hz). It is calculated by dividing wave speed by wavelength or by counting the waves that pass a point within a set timeframe.

The term that is best described as the number of waves that pass a point in one second is frequency (D). Frequency is measured in hertz (Hz), which are equivalent to cycles per second. To determine the frequency, one must count how many waves pass a marker within a certain timeframe. For example, if three waves pass a point in three seconds, the frequency would be 1 Hz since one wave is passing per second.

The relationship between wave speed, frequency, and wavelength is frequency (f) = wave speed (v) / wavelength (λ). This equation shows that if you know the wave speed and its wavelength, you can calculate the frequency. Conversely, knowing the frequency and wavelength, you can determine the wave speed.

In this question, a position time graph is shown. We need to find the corresponding velocity time graph.

In position time graph, till 1 second the object is in uniform motion and reaches a distance of 30 meters. Then the object is at till 3 seconds. After 3 seconds, the object again reaches a distance of 40 meters uniformly.

Corresponding velocity-time graph is shown in figure (3). The object is moving initially with a speed of 30 m/s. After 1 second, it comes to rest till 3 seconds then it again moves. So, the correct option is (c). Hence, this is the required solution.

Option C is the velocity-time graph matches the position-time graph

A velocity-time graph, also known as a v-t graph, is a graphical representation that shows how an object's velocity changes over time. It uses the vertical axis to represent velocity (with direction indicated by sign) and the horizontal axis for time.

The graph's slope indicates acceleration or deceleration, flat segments represent constant velocity, and zero velocity points indicate moments of rest.

Velocity-time graphs are essential tools for analyzing an object's motion, including its acceleration, deceleration, periods of rest, and changes in direction.

Answer:

Total time taken to travel 100 m = 23.82 seconds

In first case the velocity is constant and in the second case velocity is reducing by 0.2 m/s each second, so time taken will be different.

Explanation:

 A go-cart travels the first half of a 100m track with a constant speed of 5.00m/s

Time taken for first half of 100m = Distance velocity = 50/5 = 10 seconds

We have equation of motion [tex]s=ut+\frac{1}{2} at^2[/tex], where s is the displacement, u is the initial velocity, t is the time taken and a is the acceleration.

 For the second half of 100m we have

   s = 50 m, u = 5 m/s, a = [tex]-0.200m/s^2[/tex]

Substituting

  [tex]50=5t-\frac{1}{2} *0.2*t^2\\ \\ 0.1t^2-5t+50=0\\ \\ t^2-50t+500=0[/tex]

 t = 13.82 seconds or t = 36.18 seconds

 So it will take 13.82 seconds to travel second 50m

Total time taken = 10 + 13.82 = 23.82 seconds

In first case the velocity is constant and in the second case velocity is reducing by 0.2 m/s each second, so time taken will be different.

Final answer:

To determine the time it takes for a go-cart to travel a 100m track, we calculate the time for the first 50m traveled at a constant speed of 5.00m/s, which is 10 seconds. Then, for the second 50m, we factor in the deceleration of 0.200m/s^2, realizing the go-cart will not complete the second half of the track.

Explanation:

The question involves calculating the total time taken for a go-cart to complete a 100m track, which is split into two segments. The go-cart travels the first half with a constant speed, and in the second half, it experiences a deceleration due to a mechanical problem.

Step 1: Time for the first half

The go-cart travels the first 50m at a constant speed of 5.00m/s. The time (t) taken to travel this distance can be found using the formula: t = distance/speed. So, for the first 50m, t = 50m / 5.00m/s = 10 seconds.

Step 2: Time for the second half

In the second half, the go-cart slows down at a rate of 0.200m/s2, starting from the initial speed of 5.00m/s. To find the time taken to come to a stop, we use the kinematic equation v2 = u2 + 2as, where v is the final velocity (0 m/s), u is the initial velocity (5.00 m/s), a is the acceleration (-0.200m/s2), and s is the distance (50m). Solving for time, we get the second time period needed to travel the remaining distance.

Due to the deceleration, the final velocity of the go-cart will eventually reach 0 m/s before the end of the 50m stretch, which means we must first solve for the time to stop, and then add the remaining time to travel the leftover distance at 0 m/s, which is not possible, indicating the go-cart won't reach the end of the track due to the deceleration.

now in order to convert it into Ly we can say

[tex]d = 141 * 1.5 * 10^{11} = 2.115 * 10^{13} m[/tex]

now we have

[tex]d = \frac{2.115 * 10^{13}}{9.46 * 10^{15}}[/tex]

Given that force applied due to tree on car is 6000 N

and during the stop the acceleration is given as 2 m/s^2.

So here we can say that As per Newton's II law

[tex]F = m*a[/tex]

here F = force on car = 6000 N

a = acceleration of car = 2 m/s^2

now we can plug in all values above in the given equation

[tex]6000 = 2*m[/tex]

[tex]m = 3000 kg[/tex]

So here the mass of the car will be 3000 kg

The mass of the car is 3000 kg.

To calculate the mass of the car, we can use Newton's second law of motion: F = ma.

In this case, the force exerted on the car is 6000 N and the acceleration is 2 m/s².

So, using the formula F = ma, we can rearrange it to solve for mass (m). Therefore, m = F/a = 6000 N / 2 m/s² = 3000 kg.

Part a)

acceleration is defined as rate of change in velocity

so we can write

[tex]a = \frac{v_f - v_i}{t}[/tex]

here we know that

finally it will stop so vf = 0

initial speed is given as 9m/s

and the time to stop is 0.2 s

[tex]a = \frac{0 - 9}{0.2}[/tex]

[tex]a = -45 m/s^2[/tex]

Part b)

Now by 2nd law of Newton

[tex]F = ma[/tex]

given that

m = 100 kg

a = 45 m/s^2

so now using above equation

[tex]F = 100 * 45[/tex]

[tex]F = 4500 N[/tex]

so it will exert 4500 N force to stop

A. The deceleration of Alex is 45 m/s²

B. The force of impact is 4500 N

From the question given above, the following data were obtained:

a = (v – u) / t

a = (0 – 9) / 0.2

a = –9 / 0.2

a = –45 m/s²

The, negative sign indicate that the Alex is coming to rest.

F = ma

F = 100 × 45

F = 4500 N

The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops.

In a series circuit, the same amount of current flows through each component or circuit element. The voltage drop across each component in a series circuit could vary. The equivalent resistance of a series circuit is the sum of the resistances of each component.

In a series circuit, the current running through each circuit element or component, whether it's a resistor, capacitor, or inductor, remains the same. This is a fundamental concept in electricity and contrary to a parallel circuit where the voltage across each component is constant.

Let's take an example of resistors in a series circuit. The voltage drop or power dissipation across each resistor could be different. However, if you sum the voltage drops across each resistor, it adds up to the total power source input. This phenomenon can be explained using Ohm's law and the concept of equivalent resistance.

The equivalent resistance in a series circuit is the algebraic sum of individual resistances. Therefore, a key characteristic of a series circuit is that if one component fails, for instance, a bulb burns out, it affects all other components as the current flow is disturbed.

speed of first one is given as

[tex]v_1 = 1 mile \: in \: 1 min[/tex]

we also know that

1 mile = 1609 meter

also for time of motion

t = 1 min = 60 s

so in SI units the speed is given as

[tex]v = \frac{1609}{60}[/tex]

[tex]v = 26.82 m/s[/tex]

so 1 mile/min = 26.82 m/s

So here we will say that 1 mile per min is more speed than 20 m/s as we can see that 1 mile / min is 26.82 m/s in SI units after its conversion

Final answer:

Someone traveling at a mile a minute (26.67 m/s) is faster than someone traveling at 20 meters per second.

Explanation:

To determine who is faster between someone traveling a mile a minute and someone traveling at 20 meters per second, we need to convert one of the rates so that both are in the same units. First, let's convert a mile a minute to meters per second. Since one mile is equivalent to 1600 meters, and one minute is equivalent to 60 seconds, if you travel a mile in a minute, you're traveling 1600 meters in 60 seconds. Thus, the conversion is 1600 meters / 60 seconds = 26.67 meters per second.

Now, we compare:

A mile a minute = 26.67 m/s

Someone traveling at 20 m/s

It's clear that 26.67 m/s is faster than 20 m/s. Therefore, someone traveling a mile a minute is faster than someone traveling at 20 m/s.

Final answer:

Time is plotted on the x-axis of a distance versus time graph because it is the independent variable, while distance is dependent and is plotted on the y-axis.

Explanation:

On a distance versus time graph, time is typically plotted on the x-axis. This is because time is considered an independent variable. When analyzing motion, an object's distance or displacement depends on the elapsed time; hence, distance is plotted on the y-axis. The question mentions other variables like speed and velocity, which are related but represented differently in graphical form. For instance, a velocity vs. time graph has velocity on the y-axis and time on the x-axis, where the slope represents acceleration, and the area under the curve represents displacement. A graph of displacement vs. time would display a straight line if the velocity (v) is constant and time (t) is the independent variable on the x-axis.

Wave is a disturbance or energy that propagate through medium from one point to other point

So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.

This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion

This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order

For an example

[tex]y = A sin(\omega t + kx + \phi)[/tex]

so here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"

Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value

Due to this phenomenon of repeatation of its same position we can say that it is disturbance of wave is cyclic.

A cyclic or periodic wave is a repeating disturbance characterized by crests and troughs, with a wavelength defining the distance between successive crests. The wave's period is the time for a complete oscillation, and its frequency is the number of cycles per unit time.

When we say that a wave is a cyclic, or periodic, disturbance, we mean it exhibits a specific pattern that repeats itself over time. A wave motion has a series of crests and troughs; moving from one crest through a trough to the next crest constitutes one complete cycle. The wavelength is the horizontal distance between successive wave crests. Waves like those on the water surface can cause objects to experience simple harmonic motion, moving up and down as the wave passes through. The period T of the wave is the time it takes for one complete oscillation, while the frequency f is the number of cycles per unit time, given by the equation f = 1/T. Understanding these properties helps describe a wave's amplitude, frequency, wavelength, speed, and energy—all essential to characterize periodic waves and their effects on the surrounding environment.

A stone is thrown straight up. when it reaches it’s highest point, its velocity is zero and acceleration is not zero. Option b

When a stone is thrown straight up, it reaches a point where its velocity is zero because it stops momentarily before starting to fall back down. However, even at this highest point, the acceleration of the stone is not zero.

The stone is still under the influence of gravity, which provides a constant acceleration directed downwards towards the Earth's center. Therefore, the acceleration due to gravity, g, continues to act on the stone even when its velocity is zero.

The correct answer to the question is therefore (b) its velocity is zero and acceleration is not zero. The acceleration of the stone at its highest point is equal to the acceleration due to gravity, which is approximately 9.8 m/s2 directed downwards. Option  b

Δd = total displacement = d₂ - d₁ = 300 - 0 = 300 km

Δt = time interval = t₂ - t₁ = 4 - 0 = 4 h
