Hi there!

We can begin by solving for the pendulum's velocity at the bottom of its trajectory using the work-energy theorem.

Recall:
\(E_i = E_f\)

Initially, we just have Potential Energy. At the bottom, there is just Kinetic Energy.

\(PE = KE\\\\\)

Working equation:
\(\large\boxed{mgh = \frac{1}{2}mv^2}\)

Rearrange to solve for velocity:
\(gh = \frac{1}{2}v^2\\\\v = \sqrt{2gh}\\\\v = \sqrt{2(9.8)(1.5)} = 5.42 \frac{m}{s}\)

Now, we can do a summation of forces:
\(\Sigma F = T - W\)

The net force is the centripetal force, so:
\(\frac{mv^2}{r} = T - W\)

Rearrange to solve for tension:
\(T = \frac{mv^2}{r} + W\\\\T = \frac{5(5.42^2)}{4} + 5(9.8) = \boxed{85.75 N}\)

Doppler's effect:

The Doppler effect states that the frequency of sound increases as it source approaches you and it decreases as the source turns away from you.

When the ambulance drives past you, the pitch of the siren is lower. This is due to the fact that the frequency of the wavelength decreases.

A higher pitch means frequency increases and a lower pitch means frequency decreases.

Therefore, the correct answer is option B. decreases

If we have a gamma random variable with parameters (n, 1), we can approximate its size by looking at the mean or expected value of the gamma distribution. The mean of a gamma distribution with parameters (n, 1) is given by n/1 = n. Therefore, the approximate size of the gamma random variable is n.

I apologize for the confusion. To clarify, the term "size" is not commonly used to describe a gamma random variable. The size of a random variable typically refers to its sample size or the number of observations. If you are referring to the magnitude or scale of the gamma random variable, it is typically measured using the parameter known as the scale parameter, which is denoted by β in the gamma distribution. However, in your question, the parameter provided is (n, 1), which suggests that the scale parameter is equal to 1.In the gamma distribution, the shape parameter (n) determines the shape of the distribution, while the scale parameter (β) determines the scale or magnitude. Since the scale parameter is fixed at 1 in your question, the scale or magnitude of the gamma random variable is solely determined by the shape parameter (n). In summary, the approximate magnitude or scale of the gamma random variable with parameters (n, 1) is primarily influenced by the shape parameter (n), while the scale parameter (β) is fixed at 1.

Explanation:

To find the horizontal (eastward) component of the plane's velocity, we need to determine the component of the velocity in the eastward direction.

Given:

Velocity magnitude: 185 km/hr

Angle north of east: 36 degrees

To calculate the eastward component, we can use trigonometric functions. The eastward component can be found by multiplying the velocity magnitude by the cosine of the angle.

Eastward component = Velocity magnitude * cos(angle)

Eastward component = 185 km/hr * cos(36 degrees)

Using a calculator or trigonometric table, we find that cos(36 degrees) is approximately 0.809.

Eastward component ≈ 185 km/hr * 0.809

Eastward component ≈ 149.965 km/hr

Therefore, the horizontal (eastward) component of the plane's velocity is approximately 149.965 km/hr.

Answer:

a. 12.57 m/s b. 39.5 m/s² c. Her centripetal force is four times her weight.

Explanation:

a. What is Missy's linear speed on the rotor?

Missy's linear speed v = 2πr/T where r = radius = 4.0 m and T = time it takes to complete one revolution = 2.0 s

So, v = 2πr/T

= 2π(4.0 m)/2.0 s

= 4π m/s

= 12.57 m/s

b. What is  Missy's centripetal acceleration on the rotor?

Missy's centripetal acceleration, a = v²/r where v = linear velocity = 12.57 m/s and r = radius = 4.0 m

a = v²/r

= (12.57 m/s)²/4.0 m

= 158.01 m²/s² ÷ 4.0 m

= 39.5 m/s²

c. If her mass is 50-Kg, how is the centripetal force  compare to her weight?

Her centripetal force F = ma where m = mass = 50 kg and a = centripetal acceleration = 39.5 m/s².

Her weight W = mg where m = mass = 50 kg and g = acceleration due to gravity = 9.8 m/s².

So, comparing her centripetal force to her weight, we have

F/W = ma/mg

= a/g

= 39.5 m/s² ÷ 9.8 m/s²

= 4.03

≅ 4

So her centripetal force is four times her weight.

The drift velocity (v) of charge carriers in a conductor is given by the following equation: v = I / (n \(\times\) A \(\times\) q).

v = I / (n \(\times\) A \(\times\) q)

where:

v is the drift velocity, measured in meters per second (m/s)

I is the current flowing through the conductor, measured in amperes (A)

n is the number of charge carriers per unit volume of the conductor, measured in per cubic meter (\(m^(-3)\))

A is the cross-sectional area of the conductor, measured in square meters (m^2)

q is the charge of a single carrier, such as an electron, measured in coulombs (C)

This equation relates the drift velocity of the charge carriers to the current flowing through the conductor, the number of charge carriers per unit volume, the cross-sectional area of the conductor, and the charge of a single carrier. The drift velocity represents the average velocity of the charge carriers as they move through the conductor in response to an applied electric field.

The number of charge carriers per unit volume (n) depends on the material of the conductor and the temperature. In metals, the charge carriers are typically electrons, and the number density is on the order of 10^28 to 10^29 electrons per cubic meter.

The cross-sectional area (A) of the conductor is the area of the cross-section of the conductor perpendicular to the direction of the current flow, and is a measure of the amount of material available for the charge carriers to move through.

The charge of a single carrier (q) is typically the charge of an electron, which is approximately 1.6 x \(10^{-19\) coulombs.

The phase difference between the two waves detected by the receiver is 3.00 radians.

The phase difference between the two waves detected by the receiver can be calculated using the formula:

Phase difference = 2π * (distance difference / wavelength)

To find the wavelength, we can use the formula:

Wavelength = speed of sound / frequency

Given that the frequency is 260.0 Hz, we can substitute this value into the formula to find the wavelength.

Wavelength = 343 m/s / 260.0 Hz = 1.319 m

Now we can calculate the distance difference between the two speakers:

Distance difference = 2.90 m - 2.20 m = 0.70 m

Substituting the values into the formula for phase difference:

Phase difference = 2π * (0.70 m / 1.319 m) = 3.00 radians

So, the phase difference between the two waves detected by the receiver is 3.00 radians.

The magnitude of the force is -9.44 * 10^-13 * B where B is the magnetic field.

The force exerted on a charged particle in a magnetic field is given by the equation:

F = q * v * B

where q is the charge of the particle, v is its velocity, and B is the magnetic field.

Since an electron has a charge of -1.6 x 10^-19 C, the magnitude of the force exerted on it by the magnetic field is:

F = q * v * B = -1.6 x 10^-19 C * v * B

To find the velocity of the electron, we can use the equation for the work

done by an electric field on a charged particle:

W = q * V

where W is the work done, q is the charge of the particle, and V is the potential difference.

Since the work done is equal to the change in kinetic energy of the particle, we have:

W = (1/2) * m * v^2, where m is the mass of the electron

So,

q * V = (1/2) * m * v^2

Solving for v, we get:

v = sqrt(2 * q * V / m)

Plugging in the values, we get:

v = sqrt(2 * -1.6 x 10^-19 C * 100 V / 9.11 x 10^-31 kg) = 5.9 x 10^6 m/s

Finally, the magnitude of the force exerted on the electron by the magnetic field is:

F = q * v * B = -1.6 x 10^-19 C * 5.9 x 10^6 m/s * B = -9.44 * 10^-13 * B

Astronomers use rotation curves to measure the masses of individual spiral galaxies based on the speed at which stars orbit the galactic center.

The original assumption that all matter interacts with electromagnetic radiation was proven incorrect for the Milky Way galaxy. To further understand the behavior of matter in other galaxies, scientists are now focused on investigating whether this assumption still holds true in different galactic contexts. To accomplish this, they require a method to calculate the masses of individual galaxies and galaxy clusters, which can then be compared with the observed luminous matter.

Astronomers utilize rotation curves as a means to determine the masses of spiral galaxies. These curves provide insights into the speed at which stars orbit around the central region of a galaxy. The underlying principle is that the more mass there is between the stars and the galactic center, the faster the stars will orbit. By analyzing these rotation curves, scientists can estimate the amount of mass present within the galaxy, including both visible matter and potential invisible components such as dark matter.

This approach allows researchers to study the distribution of mass within galaxies and evaluate whether the observed luminous matter alone can account for the gravitational forces that govern the observed motions. By comparing the calculated masses derived from the rotation curves with the masses inferred from the observed luminosity, scientists can gain valuable insights into the existence and properties of dark matter in galaxies.
