The velocity of the duck must be 15 m/s towards the east which is explained below.

The force on a moving charge with some velocity under a magnetic field is given by:

F = qv×B

here q is the charge on the object

v is the velocity of the object

B is the magnetic field

v×B gives the direction of the force

B is towards the north, and Force is directed upwards, then velocity v should be towards the east.

Answer:

Explanation:

Just use the acceleration equation here:

\(a=-\frac{v}{t}\) where a = -9.8; velocity is also negative because it's falling down and down is negative. Filling in:

\(-9.8=-\frac{v}{8}\) so

-9.8(8) = -v and

v = 78.4 m/s downward (the word "downward" takes place of the negative sign)

The distance travelled by the car when the brakes were applied is 12.11 m

The following data were obtained from the question:

The distance travelled can be obtained as follow:

s = ut + ½at²

s = (25 × 0.45) + (½ × 8.5 × 0.45²)

s = 11.25 + (4.25 × 0.2025)

s = 11.25 + 0.860625

s = 12.11 m

Thus, the distance travelled in 0.45 s by the car is 12.11 m

To determine the amplitude of oscillation, measure the maximum displacement of the mass from its equilibrium position. This value represents the distance between the maximum and minimum positions of the mass during one complete cycle of oscillation, and it is expressed in centimeters (cm).

To calculate the frequency of oscillation, measure the time it takes for the mass to complete one cycle of oscillation (also known as the period), and then use the following formula: frequency (Hz) = 1 / period (s). The period can be calculated by measuring the time it takes for the mass to complete a certain number of oscillations and dividing that time by the number of oscillations.

To determine the spring constant of the spring, use the formula: spring constant (N/m) = mass (kg) x (2π x frequency)^2 x amplitude (m) / 4π^2. The mass of the object in this case is 0.293 kg.

Measurements of one Paramecium cell performing the barium dance show that it is moving to the left at 100 μm/s before adding barium, the average acceleration of the cell is 20 μm/s².

The formula for average acceleration can be used to get the cell's average acceleration:

\(\[ \text{Average Acceleration} = \dfrac{\text{Change in Velocity}}{\text{Time Interval}} \]\)

Given values:

Initial velocity (\(\(v_i\)\)) = 100 μm/s (to the left)

Final velocity (\(\(v_f\)\)) = 200 μm/s (to the right)

Time interval (t) = 5 seconds

The change in velocity is the difference between the final velocity and the initial velocity:

\(\[ \text{Change in Velocity} = v_f - v_i \]\)

Substitute the values:

\(\[ \text{Change in Velocity} = 200 - 100 \\\\= 100\)

Now, plug this into the formula for average acceleration:

\(\[ \text{Average Acceleration} = \dfrac{\text{Change in Velocity}}{\text{Time Interval}}\\\\ = \dfrac{100 }{5 }\)

= 20 μm/s².

Therefore, the average acceleration of the cell is 20 μm/s².

Newton's second law allows us to find the effect of the height of the ramp on the movement of the block.

Newton's second law says that force is proportional to the product of mass and the acceleration of bodies

                F = m a

Where F is the net force, m and a are the mass and acceleration of the body, the bold letters indicate vectors.

To use this expression we must set a reference frame and apply Newton's second law to each axis.

The free body diagram is a method to visualize the forces in a problem without the details of the shape of the objects, in the attached we can see a free body diagram, the x axis is placed parallel to the ramp with the positive direction in the direction of motion and the y-axis in the vertical direction

Let's write Newton's second law for each axis

y-axis

            \(N - W_y\) = 0

            N = mg cos tea

Let's write the expression for the force

x-axis

                 \(W_x - fr = ma\)

                 mg sin θ - fr = m a

The friction force is the macroscopic sum of all the microscopic forces between the two surfaces and can be written

                 fr = μ N

                 fr = μ mg cos θ

We substitute

              a = g (sin θ - μ cos θ

This expression gives the form of the block's acceleration as it descends the ramp

The height of the ramp can be found with trigonometry

            sin θ = h / L

            h = L sin θ

Let's write our equations

            a = g ( sin θ - μ cos θ)

            h = L sin θ

We substitute

            a = g (h / L - μ cos θ )

Let's analyze this expression;

It is observed that the acceleration increases with the height of the ramp

When the height increases, the angle of the ramp must increase, therefore the second term, which is a cosine function, decreases, so the acceleration also increases.

The angle decreases so much the height of the ramp decreases with the second term it increases to the point where the acceleration becomes zero

Consequently, using Newton's second law we can find the effect of the height of the ramp.

The two options that help explain why the rotation of a conducting loop between the poles of a magnet generates a potential difference are:

(A) The magnetic field changes its direction relative to the loop.

(D) The angle between the loop and the magnetic field changes.

In a simple generator, a conducting loop rotates between the poles of a magnet, resulting in the generation of a potential difference. Two factors contribute to this phenomenon.

Firstly, as the loop rotates, the magnetic field lines passing through it change their direction relative to the loop (option A). This change in the magnetic field induces a changing magnetic flux through the loop.

According to Faraday's law, this changing magnetic flux induces an electromotive force (EMF) or a potential difference across the loop. Secondly, as the loop rotates, the angle between the loop and the magnetic field changes (option D).

This change in angle alters the component of the magnetic field perpendicular to the loop, further contributing to the generation of a potential difference.

Together, these changes in the magnetic field and the angle between the loop and the magnetic field lead to the generation of a potential difference, enabling the functioning of the generator.

Therefore the correct options are (A) The magnetic field changes its direction relative to the loop and (D) The angle between the loop and the magnetic field changes.

The two ways that inertia affect the motions of the planets are:

B. It keeps the planets from flying off into space, out of the solar system.

C. It causes the planets to keep moving in the same direction as they did when they formed.

Inertia helps to keep planets in their orbits around the Sun, preventing them from flying off into space. As the planets move around the Sun, they are constantly pulled by the Sun's gravity towards the center of their orbit. However, due to their inertia, they continue to move forward, and the resulting combination of the inward pull of gravity and the outward motion due to inertia causes the planets to move in stable, elliptical orbits.

The planets formed from a cloud of gas and dust that was rotating in a particular direction. Due to the conservation of angular momentum, this rotation was transferred to the planets as they formed, causing them to continue to rotate in the same direction as they did when they formed. This is an example of how inertia affects the motion of the planets.
