Answer:

Sample Response: The first part of the graph is a straight diagonal line and the second part of the graph is a straight horizontal line. The slope of the first part of the graph is positive, indicating that the cart increased in speed, and was therefore accelerating for the first four seconds. After the fourth second, the slope of the line is zero, indicating that the cart moved at a constant speed and did not accelerate any more because the fan was turned off.

Explanation:

1. speed = distance/time taken

= 1200/5×60

= 4 m/sec.

then Siham run 4 meters each ine second.

2. if speed = distance/time taken

then time taken= distance/ speed

Va and Vb are on opposite sides of the 6.24Ω resistor, so the potential difference across the resistor is negative. The circuit given in the figure below is a combination of parallel and series combinations of resistors and sources, which can be easily solved with the help of Kirchhoff's law and Ohm's law.

Solution:

First, let us label the points that are not known. Let Va be the voltage potential at point a, and Vb be the voltage potential at point b.

Voltage potential of point b:

Vb = ε2

Since the voltage source ε2 is directly connected to point b, the voltage potential of point b will be equal to the voltage provided by the source ε2 which is 9.27V.

Voltage potential of point a:

To find the voltage potential at point a, we first need to find the current through the 6.24Ω resistor (R2) since this resistor is connected between points a and b. To find the current flowing through the resistor R2 we need to use Ohm's law:

V = IR

IR = V/R2

Since the two branches are in parallel, the voltage across them will be the same as shown below:

Va - Vb = V1

V1 = i2R2

i2R2 = (ε2 - Va)R2/R1

i1 = (ε1 - Va)/[R1 + (R2R3/R1)]

Therefore, the potential difference between point a and point b is:

Va - Vb = 4.8218V - 9.27V

= -4.4482V

Va and Vb are on opposite sides of the 6.24Ω resistor, so the potential difference across the resistor is negative.

Therefore, the potential at point b is higher than the potential at point a.

Magnitude: The magnitude of the vector is approximately 47.4 units. Direction: The direction of the vector is approximately 123.7 degrees counterclockwise from the positive x-axis.

To find the magnitude of the vector, we use the Pythagorean theorem:

Magnitude = sqrt((-25)^2 + 40^2) ≈ 47.4 units.

To find the direction of the vector, we use the inverse tangent function:

Direction = atan(40 / -25) ≈ 123.7 degrees counterclockwise from the positive x-axis.

The magnitude represents the length or size of the vector, which is found using the Pythagorean theorem. The x and y components of the vector form a right triangle, where the magnitude is the hypotenuse.

The direction represents the angle that the vector makes with the positive x-axis. We use the inverse tangent function to calculate this angle by taking the ratio of the y-component to the x-component. The result is the angle in radians, which can be converted to degrees. In this case, the direction is approximately 123.7 degrees counterclockwise from the positive x-axis.

Answer:

c = 0.4356 J/gK

Explanation:

Given the following data;

Mass = 450 grams

Initial temperature, T1 = 150°C

Final temperature, T2 = 53°C

Quantity of heat = 34500 Joules

To find the specific heat capacity of the metal;

Heat capacity is given by the formula;

\( Q = mcdt\)

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 53 - 150

dt = -97°C

Converting the temperature in Celsius to Kelvin, we have;

dt = 273 + (-97) = 176 Kelvin

Making c the subject of formula, we have;

\( c = \frac {Q}{mdt} \)

Substituting into the equation, we have;

\( c = \frac {34500}{450*176} \)

\( c = \frac {34500}{79200} \)

c = 0.4356 J/gK

The field’s direction changes with the current’s direction this conclusion is best supported by the image. Hence option A is correct.

Current is a flow of charges. it is denoted by i and expressed in ampere A. Mathematically it is expressed as i = q/t, where q is the amount of charge and t is time. Current is nothing but amount of charges flown in the unit time in the electric wire. Charge is expressed in coulomb C and time in second s. hence coulomb per second (C/s) is ampere A. Charge on electron is 1.60217663 × 10⁻¹⁹ which is called as elementary charge.

There are two types of the current, Convectional current and non-conventional current. Convectional current is the current flows from positive to negative. Non convectional current flows direction from negative to positive. Note that flow of electrons is from negative to positive. Hence direction of flow of conventional current is from positive to negative.

Explanation:

An inductor always resists any change in the current through it. The correct statement about inductors is D.


This is due to the property of inductance, which is the ability of an inductor to generate a voltage that opposes any change in the current through it. This is described by Faraday's law of electromagnetic induction. As a result, inductors are commonly used in circuits to smooth out changes in current, and also to filter out high-frequency signals.

Option A is incorrect because inductors store energy in a magnetic field, not by building up charge. Option B is incorrect because an inductor allows current to flow through it, but opposes changes in the current. Option C is incorrect because the current in the circuit will eventually become steady, but not zero. Hence option D is correct.

The free-body diagram of the cannonball is found in the attachment below

Note The question is incomplete. The complete question is as follows:

A cannonball has just been shot out of a cannon aimed 45∘ above the horizontal rightward direction. Drag forces cannot be neglected.

Draw the free-body diagram of the cannonball.

Explanation:

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.

In order to construct free-body diagrams, it is important to know the various types of forces acting on the object in that situation. Then, the direction in which each of the forces is acting is determined. Finally the given object is drawn using any given representation, usually a box, and the direction of action of the forces are represented using arrows.

In the given situation of a cannonball which has just been shot out of a cannon aimed 45∘ above the horizontal rightward direction., the forces acting on it are:

F = force exerted by the cannon acting in the direction of angle of projection

Fdrag = drag force. The drag force acts in a direction opposite to the force exerted by the cannon

Fw = weight of the cannonball acting in a downward direction

The free body diagram is as shown in the attachment below.

The magnitude of the charge on each sphere can be calculated using Coulomb's Law, which states that the force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

In this case, we can rearrange the equation to solve for the charge, Q:

Q = √(Fd2/k),

where F is the force (22 mN), d is the distance (16 mm), and k is Coulomb's constant (8.99 x 109 Nm2/C2). Plugging in the values, we get:

Q = √(22 x 10-3 N x 16 x 10-3 m2/8.99 x 109 Nm2/C2)

Q = 0.087 C.

Therefore, the magnitude of the charge on each sphere is 0.087 C.

Answer:

Momentum of ball = mass of ball x velocity of ball

P(ball) = 2 kg x 20 m/s = 40 kg*m/s

Explanation:

According to the law of conservation of momentum, the total momentum of the system (skater and ball) must remain constant before and after the throw.

Let's first calculate the momentum of the ball:

Momentum of ball = mass of ball x velocity of ball

P(ball) = 2 kg x 20 m/s = 40 kg*m/s

Since the skater was at rest before throwing the ball, the initial momentum of the system was 0. Therefore, the final momentum of the system after the throw must also be 40 kg*m/s to conserve momentum.

The momentum of the skater after the throw can be calculated as follows:

P(skater) = P(system) - P(ball)

P(skater) = 40 kgm/s - (2 kg x 20 m/s)

P(skater) = 0 kgm/s

This means that the skater has no momentum after throwing the ball. Since momentum is equal to mass times velocity, the skater's velocity must also be 0. Therefore, the skater remains at rest on the frictionless rink after throwing the ball.

According to conservation of energy, the energy of interacting bodies in a closed system remains constant. The total energy of an isolated system remains constant; it is said to be conserved over a period of time.

Elastic energy is the mechanical implicit energy stored in the configuration of a material or physical system as it's subjected to elastic distortion by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally misshaped in any manner.
