Calculate the range of wavelengths that are received by the radio in a car. Suppose that the range of frequencies of FM radio is 88.0 MHz to 108 MHz.

Answers

The range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.

To find the range of wavelengths, we use the equation for the speed of a wave

Speed of a wave

The speed of a wave v = fλ where

f = frequency and λ = wavelengthWhat is Wavelength?

This is the distance a wave travels in one cycle of the wave.

Making λ subject of the formula, we have

λ = v/f

Given that the range of frequencies of FM radio is 88.0 MHz to 108 MHz and

v = speed of electromagnetic wave = 3 × 10⁸ m/s, f' = lowest frequency = 88.0 MHz = 88.0 × 10⁶ Hz and f" = highest frequency = 108 MHz = 108 × 10⁶ HzThe longest wavelength, λ'

λ' = v/f'

= 3 × 10⁸ m/s ÷ 88.0 × 10⁶ Hz

= 0.0341 × 10² m

= 3.41 m

The shortest wavelength, λ"

λ" = v/f"

= 3 × 10⁸ m/s ÷ 108 × 10⁶ Hz

= 0.0278 × 10² m

= 2.78 m

So, the range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.

Answer: A

Explanation:

Work is defined as the inner product between the force vector and the distance traveled. Due to the energy-work theorem, the total work done is equal to the change in kinetic energy. But since there is friction, we must also take into account that frictional force. The frictional force opposes the motion of the object, and will take away energy from the object in the form of heat. Therefore, we must subtract the amount of energy done by friction from the total kinetic energy.

For your case, the answer would be A. Although, that is technically incorrect. The car does not gain energy due to friction.

An empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin. What is the speed of the coal car afterward?

Answers

Answer:

Explanation:

Mass * Velocity = Mass *Velocity

8000kg * 12m/s = (8000kg+ 24000kg) * (Final Velocity)

(96000 kgm/s) / (32000kg) = (Final Velocity)

Final Velocity = 3 m/s

The speed of the coal car afterward is 3 m/s if an empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin.

What is the law of conservation of momentum?

The momentum of the body before the contact is always equal to the momentum of the body after the collision, according to the law of conservation of momentum.

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

We have:

Mass of the empty coal car of train M(e) = 8000 kg

Speed V(e) = 12 m/s

Mass of the coal M(c)  = 24000 kg

Let's suppose the speed of the coal car afterward V(c)

M(e) ×V(e) = (M(c)+M(e))× V(c)

8000×12 = (24000+8000)×V(c)

V(c) = 3 m/s

Thus, the speed of the coal car afterward is 3 m/s if an empty coal car of a train of mass 8000 kg is moving at 12 m/s along rails. 24000 kg of coal is dumped into the car from a motionless bin.

There is no value of c such that the infinite series converges.

How to analyze the converge of an infinite series

Convergence is a characteristic of infinite series, in which a sum tends to be a given number when n tends to +∞.

In this question we must prove for which values of c the infinite series may converge.

There are different criteria to prove whether a given series converges or not, one of the most used criteria is the ratio criterion, which states that:

[tex]r = \frac{a_{k+1}}{a_{k}}[/tex], where the series converges if and only if r > 1. (1)

If we know that [tex]a_{k} = k\cdot \ln c[/tex], then the rational formula is:

[tex]r = \frac{(k+1)\cdot \ln c}{k\cdot \ln c}[/tex]

[tex]r = 1 + \frac{1}{k}[/tex]

We notice that resulting expression does not depend on c and is greater than 1. Therefore, there is no value of c such that the infinite series converges. [tex]\blacksquare[/tex]

Remark

If [tex]c[/tex] is a positive real number and [tex]a_{k} = k\cdot \ln c[/tex], for what values of [tex]c[/tex], if any, does the infinite series [tex]\sum_{k=1}^{\infty} a_{k}[/tex] converge?

[tex]a_1+a_2+a_3....+a_n[/tex]

Here, ([tex]a_n[/tex]) is the nth term of the sequence. For infinite series, the ratio criterion can be given as,

[tex]r=\dfrac{a_{k+1}}{a_k}[/tex]

If c is a positive real number and

[tex]a_k=k\ln c[/tex]

Put the value in above shown ratio,

[tex]r=\dfrac{(k+1)\ln c}{k\ln c}\\r=\dfrac{k\ln c}{k\ln c}+\dfrac{\ln c}{k\ln c}\\r=1+\dfrac{1}{k}[/tex]

With the value of r, we can say whether the series is converge or not. This value of r does not depends on c.

The acceleration of the garbage can is 2.55 m/s².

What is acceleration?

Acceleration is the rate of change of velocity with respect to time.

To calculate the acceleration of the can, we use the formula below

Formula:

ma = F-mg(η-μ)............ Equation 1

Where:

F = Horizontal forcem = mass of the cang = acceleration due to gravitya = acceleration of the canμ = Coefficient of static frictionη = Coefficient of kinetic friction

Make a the subject of the equation

a = [F-mg(η-μ)]/m.................. Equation 2

From the question,

Given:

F = 40 Nm = 12 kgg = 9.8 m/s²μ = 0.32η = 0.24

Substitute these values into equation 2

a = [40-12×9.8(0.32-0.24)]/12a = (40-9.408)/12a = 30.592/12a = 2.55 m/s²

Hence, the acceleration of the garbage can is 2.55 m/s².

Use the electron arrangement interactive to complete the table

Answers

The number of electrons that is needed to fill the following sublevels are:

1s = 2 electrons. 2s = 2 electrons. 2p = 6 electrons. 3s = 2 electrons.

What is the number of electrons needed to complete the table?

The formula to find this out is:

= 2 x (2 x Level +1)

1s = 0 levels

Number of electrons:

= 2 x (2 x 0 + 1)

= 2 electrons

2s = 0 levels

= 2 x (2 x 0 + 1)

= 2 electrons

2p = 1 level

= 2 x (2 x 1 + 1)

= 6 electrons

3s = 0 levels

= 2 x (2 x 0 + 1)

= 2 electrons
