Answer:

Assuming they're unit vectors (length of 1)

You simply add them together.

The vector pointing right can be described with X and Y

(1, 0).

The vector pointing down

(0, -1).

The numbers are taken from the axis in X and Y directions.

If you add them together you get a final vector.

(1, - 1)

This gives you -45° pointing South East.

Or 360°-45°=315°

According to the rules of continuity, if you are following a subject moving through space and the subject exits screen right (the right of the screen), they should enter the next shot from the left side of the screen. This is known as the 180-degree rule and is used to create a sense of spatial coherence between shots.

The 180-degree rule states that the camera should stay on one side of the action, meaning that a character's movement should remain consistent. To explain further, if a character is moving right, they should keep moving right as they move through the various shots. The same applies for movement left, up, and down. If a character moves off screen right, they should enter the next shot from the left. This creates a smooth and logical transition from shot to shot, which helps the audience understand the spatial relationship between characters.

In addition to the 180-degree rule, other aspects of continuity editing are used to create a cohesive narrative. Continuity editing includes matching eyelines (the direction a character is looking in a shot), matching facial expressions, and matching camera angles. All these elements, along with the 180-degree rule, help create a sense of continuity and flow between shots.

Explanation:

The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

To find the induced emf in the coil, we can use Faraday's law of electromagnetic induction, which states that the emf induced in a coil is equal to the rate of change of magnetic flux through the coil.

The magnetic flux through the coil can be calculated using the formula:

Φ = B * A * cosθ,

where B is the magnetic field, A is the area of the coil, and θ is the angle between the magnetic field and the normal to the coil.

Given:

B_initial = 0.50 T (initial magnetic field)

B_final = 2.5 T (final magnetic field)

θ = 60° (angle between the magnetic field and vertical)

r = 2.0 cm = 0.02 m (radius of the coil)

N = 100 (number of turns)

Δt = 0.40 s (change in time)

First, let's calculate the change in magnetic flux (ΔΦ):

ΔΦ = B_final * A * cosθ - B_initial * A * cosθ,

The area of the coil (A) can be calculated as the area of a circle:

A = π * r^2,

Now, substitute the values and calculate ΔΦ:

ΔΦ = (2.5 T) * (π * (0.02 m)^2) * cos(60°) - (0.50 T) * (π * (0.02 m)^2) * cos(60°).

Next, we can calculate the average rate of change of magnetic flux (ΔΦ/Δt):

average rate = ΔΦ / Δt.

Finally, we can find the induced emf (ε) by multiplying the average rate of change of magnetic flux by the number of turns in the coil:

ε = N * (ΔΦ/Δt).

Now, substitute the values and calculate the induced emf:

ε = 100 * ((2.5 T) * (π * (0.02 m)^2) * cos(60°) - (0.50 T) * (π * (0.02 m)^2) * cos(60°)) / (0.40 s).

Simplifying the expression will give us the final numerical value of the induced emf in the coil.

A disk, with radius 0.25 m and mass 4 kg, lies flat on a smooth horizontal tabletop. A string wound about the disk is pulled with a force of 8n. The angular acceleration of the disk is 4 rad/s².

The angular acceleration of a disk can be determined using Newton's second law for rotational motion, which states that the torque acting on an object is equal to its moment of inertia multiplied by its angular acceleration.

In this case, the torque (τ) is caused by the force (F) acting on the string, and the moment of inertia (I) of the disk is given by the formula I = (1/2)MR², where M is the mass and R is the radius of the disk.

Given the values:
- Radius (R) = 0.25 m
- Mass (M) = 4 kg
- Force (F) = 8 N

First, calculate the moment of inertia (I):
I = (1/2) * 4 kg * (0.25 m)² = 0.5 kg m²

Next, determine the torque (τ) caused by the force (F):
τ = F * R = 8 N * 0.25 m = 2 N m

Now, use Newton's second law for rotational motion to find the angular acceleration (α):
τ = I * α => α = τ / I = 2 N m / 0.5 kg m² = 4 rad/s²

So, the angular acceleration of the disk is 4 rad/s².

Answer:

The radius is  \(r = 3.21*10^{4} \ m\)

Explanation:

From the question we are told that  

   The density is  \(\rho = 2000 \ kg/m^3\)

    The speed is  \(v = 24 \ m/s\)

Generally the largest radius of the asteroid is mathematically represented as

      \(r = \frac{v^2}{ \sqrt{G * \rho * [\frac{4}{3} ] * \pi} }\)

=>   \(r = \frac{24^2}{ \sqrt{ 6.67*10^{-11} * 2000 * [\frac{4}{3} ] *3.142 } }\)

=>   \(r = 3.21*10^{4} \ m\)

The current required to produce the magnetic field of 1.00 × 10^-4 Tesla in the solenoid is 0.0263 A.

The formula for the magnetic field produced by a long solenoid is given by,

B = μ0ni

where B is the magnetic field, μ0 is the magnetic constant (4π×10−7 T m A−1), n is the number of turns per unit length, and i is the current in the solenoid.

The number of turns (N) in the solenoid is 1170, the length (L) of the solenoid is 0.395 m, and the magnetic field (B) produced by the solenoid is 1.00 × 10−4 T at its center.

Number of turns per unit length (n) is given by,

n=N/L
n=1170/0.395
n=2962.03 turns/m

B = μ0ni
i = B/(μ0n)

i = (1.00 × 10−4)/(4π×10−7×2962.03)
i = 0.0263 A

Therefore, the current required in the windings of the long solenoid to produce a magnetic field of magnitude 1.00 × 10−4 T at its center is 0.0263 A.

A long solenoid has a uniform distribution of 1,170 turns over a distance of 0.395 meters, and produces a magnetic field of 1.00 × 10^-4 Tesla at its center.

B = μ0ni,

where B is the magnetic field, μ0 is the magnetic constant, n is the number of turns per unit length, and i is the current in the solenoid.

The number of turns per unit length of the solenoid. Number of turns per unit length (n) is given by: n = N/L

n = 1170/0.395 = 2962.03 turns/meter. Now that we know the number of turns per unit length, we can use the same formula to calculate the current required to produce the magnetic field of 1.00 × 10^-4 Tesla in the solenoid.

i = B/(μ0n) = (1.00 × 10^-4)/(4π × 10^-7 × 2962.03) = 0.0263 A. Therefore, the current required to produce the magnetic field of 1.00 × 10^-4 Tesla in the solenoid is 0.0263 A.

We can solve this problem using the conservation of energy principle, which states that the total mechanical energy (potential energy + kinetic energy) of a system remains constant if no external work is done on the system.

At the top of the hill, the car has only potential energy, given by:

PE = mgh

where m is the mass of the car, g is the acceleration due to gravity, and h is the height of the hill.

PE = (1000 kg) x (9.81 m/s^2) x (200 m) = 1,962,000 J

At the base of the hill, the car has only kinetic energy, given by:

KE = (1/2)mv^2

where v is the velocity of the car.

Using the conservation of energy principle, we can equate the potential energy at the top of the hill to the kinetic energy at the base of the hill:

PE = KE

mgh = (1/2)mv^2

Canceling the mass on both sides, we get:

gh = (1/2)v^2

Solving for v, we get:

v = sqrt(2gh)

Substituting the given values, we get:

v = sqrt(2 x 9.81 m/s^2 x 200 m) = 44.3 m/s

Therefore, the velocity of the car at the base of the hill is approximately 44.3 m/s.

Destructive and constructive interference, resonant frequency, Doppler shift, resonance, and standing waves are all phenomena related to wave behavior.

Destructive interference occurs when two waves meet and their amplitudes cancel each other out, resulting in a reduced or zero amplitude. This can occur when two waves are out of phase, causing their crests to align with the troughs of the other wave.

Resonant frequency refers to the natural frequency at which an object or system vibrates with maximum amplitude. When an external force is applied at the resonant frequency, the object or system exhibits resonance, leading to increased amplitudes.

Constructive interference happens when two waves meet and their amplitudes add up, resulting in an increased amplitude. This occurs when the crests of both waves align with each other, creating a larger combined amplitude.

Doppler shift is the change in frequency or wavelength of a wave observed by an observer moving relative to the source of the wave. It is commonly experienced as the change in pitch of a sound as a moving vehicle approaches or recedes.

Resonance occurs when an object is forced to vibrate at its natural frequency, resulting in large amplitude oscillations. This phenomenon can be observed in musical instruments or structures.

Standing waves are formed when two waves of the same frequency and amplitude traveling in opposite directions interfere with each other, resulting in nodes (points of no displacement) and antinodes (points of maximum displacement) along the wave.

To calculate the total mass, you must use the formula: Force / acceleration.

To calculate the acceleration you must use the formula: Force / mass.

a)Therefore, the work required to assemble this charge distribution is approximately 0 J. b)Therefore, the magnitude of the electric field at a point (0, +3 m) on the y-axis is 90 kN/C. c)Therefore, the magnitude of the force on the 1 μC charge is 0.03 N (approximately) are the answers.

Given information: A point charge of +10 μC is at (+3 m, 0 m) on the x-axis and a point charge of +10 μC is at (-3 m,0 m).

a. Determine the work required to assemble this charge distribution. The work done to assemble this charge distribution is the sum of the work done to bring each charge to its respective position.

It can be calculated using the formula as follows;

W = (1/4πε0)(q1q2/r1 + q1q2/r2)

where

ε0 = permittivity of free space = 8.85 × 10−12 C2/Nm2q1

= +10 μC, q2 = +10 μCr1 = +3m,

r2 = +3m

W = (1/4πε0)(q1q2/r1 + q1q2/r2)

= (1/4π × 8.85 × 10−12 × 10 × 10 × 106 )/(3 + 3) J= 4.44 × 10−7 J ≈ 0 J (approximately).

Therefore, the work required to assemble this charge distribution is approximately 0 J.

b. Find the magnitude of the electric field at a point (0,+3 m) on the y-axis. The electric field at a point on the y-axis due to the charges can be calculated by using the formula as follows;

E = (1/4πε0)(q/r1^2 − q/r2^2),

where q = +10 μCr1 = +3m,

r2 = +3mE = (1/4πε0)(q/r1^2 − q/r2^2)

r2= (1/4π × 8.85 × 10−12 × 10 × 106 )/(32 − 32) N/C

r2= (1/4πε0)(q/r1^2)= (1/4π × 8.85 × 10−12 × 10 × 106 )/(3^2) N/C

r2= 9 × 10^4 N/C. To get the answer in kN/C,

the answer can be divided by 1000.

E = 9 × 10^4 x 10^-3 = 9 × 10^1 kN/C C = 90 kN/C.

Therefore, the magnitude of the electric field at a point (0, +3 m) on the y-axis is 90 kN/C.

c. A charge q= +1 μC is placed at a point (0,+3 m) on the y-axis. Find the magnitude of the force on the 1 μC charge.

The force on the 1 μC charge due to the charges can be calculated using Coulomb's law.

Coulomb's law is given by;

F = (1/4πε0)(q1q2/r^2)

where

ε0 = permittivity of free space = 8.85 × 10−12 C2/Nm2q1

= +10 μC, q2 = +1 μCr = +3mF

= (1/4πε0)(q1q2/r^2)

=(1/4π × 8.85 × 10−12 × 10 × 1 × 106 )/(3^2) N
