where represents an amount of charge that passes a point in the wire over some amount of time, .

Electric current is the movement of an electric charge. Amperes are the units used to measure electric current. The ampere has the unit sign A.

When studying electricity, both coulombs and amperes are frequently utilised, but it's vital to keep in mind that they measure distinct things. Charge is measured by the coulomb, while the flow of charge is measured by the ampere.

One coulomb of charge passes a spot in a wire in one ampere of current in one second.

Any amount of time can be used to gauge how much charge is transferred; just that it cannot exceed one second.

Simply dividing a charge's amount by the length of time it was measured yields current.

Consumers will likely pay more for these items at the grocery store as a result of the mentioned shortage. The growers will be able to charge more for each piece of fruit if there is a shortage of fruits, which is the reason for this.

The juice companies will be forced to pay extra for the fruits they need to make the juices as a result of this increase in manufacturing expenses. In order to offset their increased expenses, the juice factories will most certainly raise their pricing. Therefore, the most likely consequence of the shortfall is that consumers would have to spend extra at the grocery store for fruit juices.

0.033 kg m/s (rounded to the closest tenth of a kg m/s) is the change in momentum of the apple between 0 and 20 milliseconds.

P equals F net t. F net t F net The impulse-momentum theorem is an equation that relates the quantities t and. The impulse is defined as the average net external force multiplied by the time it takes for that force to act. It is equivalent to the momentum change.

By integrating the net force across the time range of 0 ms to 20 ms, the impulse can be calculated:

Impulse = ∫F_net dt (from t=0 ms to t=20 ms)

When the net force is constant, we can divide the time period into three segments as follows:

from 0 ms to 5 ms: F_net = 0 N

from 5 ms to 15 ms: F_net = 4 N

from 15 ms to 20 ms: F_net = -2 N

When we add the results of the impulse formula for each interval, we get:

Impulse = (0 N) × (5 × 10^-3 s) + (4 N) × (10 × 10^-3 s) + (-2 N) × (5 × 10^-3 s)

= 0 N.s + 0.04 N.s - 0.01 N.s

= 0.03 N.s

Δp = Impulse = 0.03 N.s

The apple weighs 1.1 kg, hence its change in momentum is as follows:

Δp = 1.1 kg × 0.03 N.s = 0.033 kg m/s.

The machine's efficiency is 81.61%, indicating that it converts 81.61% of the input energy into useful output energy, while the remaining percentage is lost as waste or dissipated in the process.

To calculate the efficiency, we can use the formula:

Efficiency = (Actual Output / Design Capacity) × 100

Given:

Actual Output = 7,407

Design Capacity = 9,050

Substituting the values into the formula:

Efficiency = (7,407 / 9,050) × 100

          = 0.817 × 100

          = 81.61%

Therefore, the efficiency of the machine is 81.61%.

Efficiency is a measure of how effectively a machine or system is utilizing its available capacity. In this case, the machine has a design capacity of 9,050 units, but it only produced an actual output of 7,407 units.

By dividing the actual output by the design capacity and multiplying by 100, we find that the machine's efficiency is 81.61%. This indicates that the machine is operating at approximately 81.61% of its full capacity.

A higher efficiency percentage would indicate a more optimal utilization of the machine's capacity, while a lower percentage suggests room for improvement in maximizing output.

Answer:

In a coiled spring, the particles of the medium vibrate to and fro about their mean positions at an angle of

A. 0° to the direction of propagation of wave

Explanation:

The waveform of a coiled spring is a longitudinal wave, which is made up of vibrations of the spring which are in the same direction as the direction of the wave's advancement

As the coiled spring experiences a compression force and is then released, it experiences a sequential movement of the wave of the compression that extends the length of the coiled spring which is then followed by a stretched section of the coiled spring in a repeatedly such that the direction of vibration of particles of the coiled is parallel to direction of motion of the wave

From which we have that the angle between the direction of vibration of the particles of the coiled spring and the direction of propagation of the wave is 0°.

A ball sitting still on the pitch obeys Newton's first law.

According to the first law of the Newton, a body would continue to be at rest or in state of uniform motion unless it is acted upon by an external force.

In this case, we have a football that is sitting still on a pitch. This ball is held by the force of inertia and the forces that act on it are balanced. If on the other hand this ball is not kicked (action of eternal force), it would continue to sit still on the pitch.

Answer:

6,653.34 J

Explanation:

Kinetic energy can be found using the following formula.

\(KE=\frac{1}{2} mv^2\)

where m is the mass in kilograms and v is the velocity in m/s.

The object is 108 kilograms and is moving at a speed of 11.1 m/s. Therefore, the mass is 108 kg and the velocity is 11.1 m/s.

m=108 kg

v=11.1 m/s

Substitute these values into the formula.

\(KE=\frac{1}{2}*108*11.1^2\)

Evaluate the exponent first. 11.1^2 is the same as 11.1*1.11, which is equal to 123.21

\(KE=\frac{1}{2} *108*123.21\)

Multiply 108 and 123.21

\(KE=\frac{1}{2}*13306.68\)

Multiply 1/2 and 13306.68

\(KE=6653.34\)

The kinetic energy of the object is 6,653.34 Joules (kg m2/s^2)

The weight of a \(45 kg\) box is \(441.45 N\).

Weight refers to the measure of the force exerted on an object due to the gravitational pull of the Earth.

Given the mass of the box is \(m=45 kg\).

The weight of an object (\(W\)) can be found by multiplying the mass of the object (\(m\)) by the acceleration due to gravity (\(g\)).

So, \(W=mg\).

It is known that acceleration due to gravity, \(g=9.81 m/s^2\).

Hence, the weight of the box, \(W=(45kg)\times (9.81 m/s^2)\).

\(\Rightarrow W=441.45 (kg\cdot m/s^2)\\\Rightarrow W=441.45 N\)

Therefore, the weight of the box is \(441.45 N\).

The electric force easily overcomes gravity and lifts the paper without touching it because electric forces act on charged particles within the paper, creating repulsion or attraction that can counteract or exceed gravity.

The electric force arises from the interaction between charged particles. When an object, such as a piece of paper, acquires a net charge, it creates an electric field around it. If another charged object, such as an electrically charged balloon or an electroscope, is brought near the paper, the charges within the paper experience an electric force.

If the charged object and the charged particles within the paper have like charges (both positive or both negative), the electric force between them is repulsive. This repulsive force can be strong enough to overcome the force of gravity acting on the paper, causing it to lift off the surface.

Alternatively, if the charged object and the charged particles within the paper have opposite charges, the electric force between them is attractive. In this case, the attractive electric force can also exceed the force of gravity and lift the paper.

If the charged object is sufficiently close to the paper and has a significant charge, the electric force can easily overcome the relatively weak force of gravity.

The electric force easily overcomes gravity and lifts the paper without touching it because electric forces act on charged particles within the paper, creating repulsion or attraction that can counteract or exceed gravity, causing repulsion or attraction between the charges.

Explanation:

This problem can be solved using the principle of conservation of momentum and quantity of movement. This problem can be solved using the principle of conservation of momentum and quantity of movement. Where the amount of movement of anybody is equal to the sum of the original moment plus the applied momentum.

\((m_{1}*v_{1})+Imp_{1-2}=(m_{1}*v_{2})\)

where:

m₁ = mass of the trolley = 1 [kg]
