The new eyepiece you should choose is 10 mm.

The magnification of a telescope is determined by the ratio of the focal length of the objective lens (or mirror) to the focal length of the eyepiece. In this case, you want Saturn's image to appear twice as large, which means you need to double the magnification. Since the objective lens remains the same, the change in magnification can only be achieved by changing the focal length of the eyepiece.

Using the formula for magnification:

Magnification = (Focal length of objective) / (Focal length of eyepiece)

To double the magnification, the new focal length of the eyepiece should be half of the original focal length, which is 10 mm.

Therefore, by choosing the 10 mm eyepiece, you will achieve the desired magnification to make Saturn's image appear twice as large while keeping the objective unchanged.

Answer:

The answer is d =10^6.43 Mpc

Explanation:

Solution

To calculate the absolute magnitude of the star, we apply or use the relation with the period

Mv = - [ 2.76 (log₁₀ (P) - 1.0)] -4.16

Here P =+ 0.5 days

Mv = - 0.569

To calculate m, we have the following relation given below:

Mₓ = - 2.5 Log₁₀ (Fₓ/Fₓ,0)

Fₓ,0 = 1 w/m² (This is assumed)

Fₓ = 2.3 * 10^-11 W/m^2 (Given)

Thus

Mₓ = - 2.5 Log₁₀ (2.3 * 10^ ⁻11

Mₓ = 26.595

Now, applying the formula we have the following given below:

d = ₁₀ ( Mₓ -Mv + 5)/5

d =₁₀ (26.595 - 0.569 +5)/5

d =10^6.43 Mpc

Answer:

Explanation:

It will be B.

The correct answer is the same mass and less weight.

The weight decreases. Your weight will be 1/6 of the weight on the moon that you had on Earth. This is because the mass of the moon is less hence the gravitational pull is very low compared to Earth.

Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.

To calculate the speed of a ball when it leaves the projectile launcher after the spring is compressed by 3.75 cm, we need to know the value of the spring constant (k).

The speed of the ball can be determined using the principle of conservation of mechanical energy. When the spring is compressed, it stores potential energy, which is converted into kinetic energy when the ball is launched.

The potential energy stored in the spring can be calculated using the equation:

Potential Energy = (1/2) * k * x²,

where k is the spring constant and x is the compression distance (3.75 cm = 0.0375 m).

To determine the speed, we equate the potential energy to the kinetic energy: (1/2) * k * x² = (1/2) * m * v²,

where m is the mass of the ball and v is the speed we want to find.

By rearranging the equation and solving for v, we get:

v = sqrt((k * x²) / m).

However, to calculate the speed, we need the value of the spring constant (k) and the mass of the ball (m). Without these values, we cannot provide a specific numerical answer.

The situation that is understood using Newton's first law of motion, and not Newton's second law of motion are "A parked car" and "A car traveling in a straight line on cruise control"

Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force. This law is best suited for situations where there is no net force acting on an object, such as a parked car or a car traveling in a straight line on cruise control.

On the other hand, Newton's second law of motion relates the acceleration of an object to the net force acting on it and its mass. This law is better suited for situations where there is a net force acting on an object, such as a free falling rock or a car on cruise control turning in a circle.

Therefore, the situations best understood using Newton's first law of motion are the parked car and the car traveling in a straight line on cruise control, and the situations best understood using Newton's second law of motion are the free falling rock and the car on cruise control turning in a circle.

The frequency of the light with the given wavelength in water is 3.75 × 10¹⁴ Hz.

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

Both frequency and wavelength are inversely proportional to each other.

Using the wavelength, frequecy and speed relation;

λ = v / f

Where λ is wavelength, v is speed and f is frequency.

Given the data in the question;

We know that frquency in water is the same as frequecy in air, it doesnt change due to medium.

From the expression above, the frequency of the light will be;

λ = v / f

f = Vw / λw

But,

Refractive index u = velocity of light in air / velocity of light in medium ( water )

So,

Vw = ( 3×10⁸m/s × 1 ) / 1.33

Vw = 2.25 × 10⁸m/s

Hence,

f = Vw / λw

f = ( 2.25 × 10⁸m/s ) / ( 6.0 × 10⁻⁷m )

f = 3.75 × 10¹⁴ s⁻¹

To determine the work done in compressing the spring 7 inches, we can use Hooke's law to calculate the variable force exerted on the spring. By applying Hooke's law, we find that the work done is 19.6 Joules.

Hooke's law states that the force exerted by a spring is directly proportional to the displacement or compression of the spring. Mathematically, it can be expressed as F = kx, where F is the force, k is the spring constant, and x is the displacement.

Given that a force of 4 pounds compresses a 15-inch spring by 5 inches, we can use this information to find the spring constant, k. Rearranging Hooke's law, we have k = F/x = 4/5 = 0.8 pounds per inch.

To determine the work done in compressing the spring 7 inches, we need to calculate the variable force exerted. Since the force varies with displacement, we can integrate the force function with respect to displacement. Integrating F = kx from x = 0 to x = 7, we find that the work done is equal to the area under the force-displacement curve.

\(W = \int\limits^7_0 {kx} \, dx\)

W = 0.8 * [(1/2) * \(x^2\)] (0 to 7) = 0.8 * (1/2) * (\(7^2\) - \(0^2\)) = 0.8 * (1/2) * 49 = 19.6 J.

Therefore, the work done in compressing the spring 7 inches is approximately 19.6 Joules.

The maximum possible efficiency of an engine operating between the given two temperatures is 10.38%.

Maximum efficiency that is obtained when the heat engine is operating between two temperatures is called Carnot Efficiency.

The efficiency of heat engines generally increases with the operating temperature. Advanced structural materials that helps engines to operate at higher temperatures is an active area of research.

The efficiency of Carnot engine = 1

No engine has 100 % efficiency as per the Kelvin Planck statement. Sink temperature is always  less than the source temperature, therefore  of Carnot cycle efficiency becomes less than 100 %.

Given T1 = 35°C , T2= 3°C

Efficiency =( (T1 - T2)/T1) × 100

T1= 35+273 = 308 K

T2 = 3 +273= 276 K

1. The electric field in the region between the plates is 4.00 MV/m.

2. The surface charge density on the positive plate is 100.0 uC/m².

3. If the plates of the capacitor are brought closer together while the charge remains constant, the electric field between the plates will increase.

4. If the plates of the capacitor are moved closer together while the charge remains constant, the surface charge density will increase.

5. If the plates of the capacitor are moved closer together while the charge remains constant, the potential difference will decrease.

1. To calculate the electric field, we use the formula E = V/d, where E is the electric field, V is the potential difference, and d is the distance or gap width between the plates. Plugging in the given values, E = 800 V / (0.200 mm * 10⁻³), we get E = 4.00 MV/m.

2. The surface charge density can be calculated using the formula σ = Q/A, where σ is the surface charge density, Q is the charge, and A is the area of the plate. Plugging in the given values, σ = 20.0 C / (0.200 mm * 10⁻³ * 1 m), we get σ = 100.0 uC/m².

3. The electric field between the plates is determined by the potential difference and the distance between the plates. If the distance is decreased while keeping the charge constant, the electric field will increase. This is because the electric field is inversely proportional to the distance between the plates according to the formula E = V/d.

4. The surface charge density is determined by the charge and the area of the plate. If the distance between the plates is decreased while keeping the charge constant, the area of the plate effectively decreases. As a result, the surface charge density will increase because the same amount of charge is distributed over a smaller area.

5. The potential difference across the capacitor is determined by the electric field and the distance between the plates. If the distance between the plates is decreased while keeping the charge constant, the electric field will increase (as explained in part 3). Since the potential difference is directly proportional to the electric field according to the formula V = Ed, decreasing the distance will lead to a decrease in the potential difference.

During phase shift, the substance's molecules' average kinetic energy remains constant.

Simply put, molecules move more quickly as kinetic energy rises. Nevertheless, molecules change phases when potential energy rises. The molecule changes phases as a result of an increase in potential energy.

In a phase change, matter moves from one state to another either by gaining energy through heat and entering a more energetic state, or by losing energy through heat and entering a state with lower energy.

The energy supplied during phase change is only used to separate the molecules; none of it is used to boost the kinetic energy of the molecules. Therefore, since the molecules' kinetic energy is constant, its temperature won't increase.
