D)both A and B

Explanation:

Since the mast is a conductor and connected to the plastic so charge transfer takes place between the mast and the tube because the mast is connected to the ground with wire which is called grounded which means its potential is 0 equal to the ground so that charge can transfer from plastic tube to the ground. This is why the wire is used to connect the metal mast to the Earth.

(A) The angle of this in polar coordinates is 30⁰.

(B) The North/South and East/West components of its displacement is 250 m and 433 m respectively.

60° N of W lies in the fourth quadrant;

θ = 90 - 60 = 30⁰

in polar coordinate = (r,θ) = (500 m, 30⁰)

Dy = D sinθ

Dy = 500 m x sin(30) = 250 m

Dx = D cosθ

Dx = 500 m x cos(30) = 433 m

Thus, the angle of this in polar coordinates is 30⁰.

The North/South and East/West components of its displacement is 250 m and 433 m respectively.

Answer:

The magnitude and direction of the centripetal acceleration will be:

\(a_c=5\) m/s²   (towards the center of the circle).

Explanation:

Given

Using the formula to determine the centripetal acceleration

\(a_c=\frac{v^2}{r}\)

\(a_c=\frac{\left(10\right)^2}{20}\)

\(\:a_c=\frac{100}{20}\)

\(a_c=5\) m/s²

As the truck is moving in a circle, therefore the direction is towards the center of the circle.

Hence, the magnitude and direction of the centripetal acceleration will be:

\(a_c=5\) m/s²   (towards the center of the circle).

In F test statistics, the larger sample variance is placed in the numerator. Hence, the tabled F ratio is always greater than 1.00 (option b).

The F test is used to compare the variances of two samples and determine if they are significantly different from each other. The F ratio is calculated by dividing the larger sample variance by the smaller sample variance. If the larger sample variance is in the numerator, the F ratio will always be greater than 1.00. If the F ratio is less than 1.00, it means that the smaller sample variance is in the numerator and the larger sample variance is in the denominator.

Explanation:

ANSWER

False

EXPLANATION

Magnification is a measure of an image's size compared to the size of the object that formed the image.

Since magnification is a ratio that is proportional to the sizes of the image and object, it follows that if magnification is less than 1, the image is smaller than the object, if magnification is equal to 1, the image and object are the same size and if magnification is greater than 1, the image is larger than the object.

Therefore, it is False.

To further stretch the spring from l m to L m, the work done is given by W = 0.5k (L² - l²), where k is the spring constant and l and L are the initial and final lengths respectively.

Given, it requires a force of 18 N to hold a spring stretched l m beyond its natural length.Since the work done is equal to the change in potential energy, therefore, the work required to further stretch the spring from l m to L m is given by:

W = Uf - Ui

= 0.5 k L² - 0.5 k l²

Now, we have k = F / x where F is the force required to stretch the spring by a distance x.So,

k = 18 / l

Also, the force required to stretch the spring to length L is given by:

F' = k (L - l) = 18 (L - l) / l

Therefore, the work done is given by:

W = 0.5 k (L² - l²) = 0.5 x 18 / l x (L² - l²) = 9 (L² - l²) / l

Hence, the work done to further stretch the spring from l m to L m is 9 (L² - l²) / l J.

Therefore, the work required to stretch the spring from l m to L m is given by the equation: W = 9 (L² - l²) / l.

Answer:

Earth’s gravitational force is stronger

Explanation:

Earth’s gravitational force is stronger than the moon because of the presence of more massive objects in earth; on the flip side, the moon’s gravity is weaker than the earth due to smaller in size as compared to the earth. Earth gravity is denoted by g; conversely, moon gravity is denoted by gm

Answer: The greater an object's mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That's why the moon isn't pulled out of Earth's orbit by the gravity of larger planets or by the sun.

Answer:

Explanation:

average speed = 90 km / hr

Let the total distance be 2 d .

time required to cover the time = 2 d / 90

time taken   to cover distance d at 50 km /h = d / 50

time required to cover the  nd half = 2 d / 90 -  d / 50

.02222 d  - .02 d = .002222 d

speed required = d/2 / .002222d

The time required to cover the Moon to a depth of 1.20 meters with micrometeorites.

To find out how long it would take to cover the Moon to a depth of 1.20 meters with micrometeorites, we can calculate the volume of the Moon and then divide it by the volume of one micrometeorite. Let's break down the calculation step by step:

Calculate the volume of the Moon:

The average radius of the Moon is approximately 1.737 ×10⁶ meters. Using the formula for the volume of a sphere, V = (4÷3)πr³, we can calculate the volume of the Moon.

\(V_{moon}\) = (4÷3)π(1.737 × 10⁶)³

Calculate the volume of one micrometeorite:

The diameter of the micrometeorite is given as 1.30 ×10⁽⁻⁶⁾ meters, which means the radius is half of that.

\(r_{meteorite}\) = (1.30 × 10⁽⁻⁶⁾)÷2

Using the formula for the volume of a sphere, V = (4÷3)πr₃, we can calculate the volume of one micrometeorite.

\(V_{meteorite}\) = (4÷3)π((1.30 × 10⁽⁻⁶⁾)÷2)³

Calculate the number of micrometeorites needed to fill the Moon:

To find the number of micrometeorites required to fill the Moon, we divide the volume of the Moon by the volume of one micrometeorite.

\(N_{meteorites}\) = \(V_{moon}\) ÷ \(V_{meteorite}\)

Calculate the time to fill the Moon:

Since one micrometeorite strikes each square meter of the Moon each second, we can equate the number of micrometeorites needed to fill the Moon to the number of seconds it would take.

Time = \(N_{meteorites}\) ÷ (1 m²/s)

Convert seconds to years:

Finally, we convert the time in seconds to years by dividing by the number of seconds in a year (assuming 365.25 days in a year and 24 hours in a day).

\(Time_{years}\) = Time ÷ (365.25 days/year × 24 hours/day × 3600 seconds/hour)

Performing these calculations will give us the time required to cover the Moon to a depth of 1.20 meters with micrometeorites.

Answer:

The pressure of the box on the floor is 200 Pa

Explanation:

Given,

Length of the box=0.5m

Width of the box= 0.1m

∴Area of the box, A= (0.5 X 0.1) sq.m

                                = 0.05 sq.m

We know,

Pressure, P= F/A

                  = 10/0.05 Pa

                  = 200 Pa

∴The pressure of the box on the floor is 200 Pa

The equation n · (r - r₀) = 0 represents the vector equation of a plane, where n is the normal vector and (r - r₀) is any vector on the plane, with the dot product ensuring perpendicularity.

The equation you provided, n · (r - r₀) = 0, does indeed represent the vector equation of a plane. Let's break it down to understand its components:

n represents the normal vector to the plane. It is a vector that is perpendicular to the plane and defines its orientation.

r represents a position vector that describes any point in space, and r₀ represents a specific position vector corresponding to a point on the plane.

The expression (r - r₀) represents a vector that originates from the point r₀ and points to any other point on the plane.

The dot product (·) of two vectors measures the degree of alignment between them. In this case, the dot product of the normal vector n and the vector (r - r₀) is taken.

When two vectors are orthogonal (perpendicular) to each other, their dot product is zero.

Therefore, the equation n · (r - r₀) = 0 implies that the normal vector n is perpendicular to the vector (r - r₀), indicating that the plane is perpendicular to the direction given by (r - r₀).

In summary, the equation n · (r - r₀) = 0 represents the vector equation of a plane, where n is the normal vector and (r - r₀) is any vector on the plane.
