Answer:

kicking ball and throwing stone

Answer:

- Pushing a shopping cart

- Kicking a soccer ball

Explanation:

    The second law states "It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it."

    So two examples would be pushing / kicking anything (shopping cart or soccer ball for example) and riding a bicycle (bike = mass and you are the force)

Answer:

A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.

Explanation:

Generally, stream flows are measured in CFS   = Cubic Feet per Second

Newton's Second Law of Motion states "The rate of change of momentum of a body is directly proportional to the applied unbalanced force in the direction of force".

The hockey player is moving at a speed of 9. 5 m/s. if it takes him 2 seconds to come to a stop under constant acceleration, will be s = 9.5 m.

The branch of physics that defines motion with respect to space and time, ignoring the cause of that motion, is known as kinematics. Kinematics equations are a set of equations that can derive an unknown aspect of a body’s motion if the other aspects are provided.

These equations link five kinematic variables:

Displacement (denoted by Δx)

Initial Velocity v0

Final Velocity denoted by v

Time interval (denoted by t)

Constant acceleration (denoted by a)

These equations define motion at either constant velocity or at constant acceleration. Because kinematics equations are only applicable at a constant acceleration or a constant speed, we cannot use them if either of the two is changing.

v = u + at

0 = 9.5 + a (2)

a = - 9.5 /2  m/\(s^{2}\)

\(v^{2}\) = \(u^{2}\) + 2as

0 =  \((9.5)^{2}\) + 2* (- 9.5 /2) * s

-  \((9.5)^{2}\)  = - 9.5 s

s = 9.5 m

The longitude of the lost ship, assuming solar noon at the location and a time of 12:30 AM at the Prime Meridian, would be approximately 7.5 W.

To determine the longitude, we can use the concept of solar time and the time difference between the location of the lost ship and the Prime Meridian. Solar time is based on the position of the Sun in the sky, and it varies as we move across different longitudes.

Given that it is solar noon at the lost ship's location, it means the Sun is directly overhead at that moment. However, at the Prime Meridian (Greenwich, England), the time is 12:30 AM. The time difference between the two locations is 12 hours and 30 minutes.

Since each hour corresponds to 15 degrees of longitude (360 degrees divided by 24 hours), we can calculate the longitude by dividing the time difference by 1 hour per 15 degrees. In this case, the time difference of 12 hours and 30 minutes corresponds to 7.5 hours, which translates to 7.5 times 15 degrees, resulting in a longitude of 112.5 degrees west or 7.5 W.

As for the second part of the question, if Lake Tahoe is located at 120 degrees west longitude and it is currently solar noon, we can determine the solar time at 15 degrees west longitude. Each degree of longitude corresponds to 4 minutes of time (360 degrees divided by 24 hours), so the time difference between 120 degrees west and 15 degrees west is 105 degrees.

Multiplying 105 degrees by 4 minutes gives us a time difference of 420 minutes. Adding this to the solar noon time (12:00 PM), we get a solar time of 7:00 PM at 15 degrees west longitude. Therefore, the solar time at 15 degrees W would be 7:00 PM.

The density of the 100 kg mass after the volume is decreased by 2% due to compression is 2,040 kg/\(m^{3}\).

What is Mass?

Mass is a fundamental physical property of matter that measures the amount of matter in an object. It is a scalar quantity that does not depend on the object's position or orientation in space, unlike weight which is a force that depends on gravity.

The initial density of the 100 kg mass is 2,000 kg/\(m^{3}\). We can use the formula for density which is:

density = mass / volume

To calculate the initial volume, we rearrange the formula as:

volume = mass / density

volume = 100 kg / 2,000 kg/\(m^{3}\)

volume = 0.05 m3

When the volume is decreased by 2%, the new volume becomes:

new volume = initial volume - (2% of initial volume)

new volume = 0.05 \(m^{3}\) - (0.02 x 0.05 m3)

new volume = 0.049 \(m^{3}\)

Using the formula for density again, we can calculate the new density:

new density = mass / new volume

new density = 100 kg / 0.049 \(m^{3}\)

new density = 2,040 kg/\(m^{3}\)

Explanation:

m = 0.5kg

u ( initial velocity) = 0m/s

v ( final velocity) =?

a = 9.8m/s^2

d (displacement) = 30m

Since u don't have time, u only have the choice to use this formula

The time it takes for the capacitor to fully discharge is about 5 times the time constant (5RC), or 337.5 μs.

When the 0.50 μF capacitor is charged to 70 V, it stores electrical energy in its electric field. However, when it is connected in series with a 25 ω resistor and a 110 ω resistor, the capacitor starts to discharge through the resistors. The time constant of the circuit (RC) is given by the product of the resistance and capacitance, which is 0.5 μF x (25 + 110) ω = 67.5 μs.

As the capacitor discharges, the voltage across it decreases exponentially according to the formula V(t) = V0 * e^(-t/RC), where V(t) is the voltage across the capacitor at time t, V0 is the initial voltage (in this case 70 V), and e is the mathematical constant. When t = RC, the voltage across the capacitor has decreased to about 37% of its initial value, or 25.9 V.

Eventually, the capacitor will fully discharge, meaning that the voltage across it will be 0 V. At this point, all of the energy that was stored in the capacitor has been dissipated through the resistors in the form of heat. The time it takes for the capacitor to fully discharge is about 5 times the time constant (5RC), or 337.5 μs in this case.

The charge on each capacitor is:
Q1 = 90μC
Q2,3 = 66.6μC
Q4 = 143.4μC

To find the equivalent capacitance between points a and b, we need to analyze the circuit and simplify it using equivalent capacitance formulas.
Starting with the capacitors in parallel, C2 and C3 are connected in parallel across the voltage source. Their equivalent capacitance can be calculated as:
C2C3 / (C2 + C3)= 8μF * 10μF / (8μF + 10μF)= 4.44μF (rounded to two decimal places)
Next, we can simplify the circuit by replacing C2 and C3 with their equivalent capacitance of 4.44μF. Now, we have two capacitors in series (C1 and the equivalent capacitance of C2 and C3). The equivalent capacitance of capacitors in series can be calculated as:
C1(C2C3 / (C2 + C3)) / (C1 + C2C3 / (C2 + C3))= 6μF(4.44μF) / (6μF + 4.44μF)= 2.56μF (rounded to two decimal places)
Therefore, the equivalent capacitance between points a and b is 2.56μF.
To calculate the charge on each capacitor, we can use the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage across the capacitor. Since we know the equivalent capacitance and voltage across the circuit (ΔV a​ b=15.0V), we can calculate the charge on each capacitor.
Starting with C1, its charge can be calculated as:
Q1 = C1ΔV a​ = 6μF * 15.0V= 90μC

Moving on to the capacitors in parallel (C2 and C3), they have the same voltage across them and can be treated as a single capacitor with the equivalent capacitance we calculated earlier. The charge on this equivalent capacitor can be calculated as:
Q2,3 = C2C3ΔV a​ b

= 4.44μF * 15.0V
= 66.6μC
Finally, we can use the fact that the charge is conserved in the circuit (i.e. the total charge on the circuit is the same as the sum of charges on each capacitor) to find the charge on C4. It can be calculated as:
Q4 = Qtotal - Q1 - Q2,3
= 300μC - 90μC - 66.6μC
= 143.4μC
Therefore, the charge on each capacitor is:
Q1 = 90μC
Q2,3 = 66.6μC
Q4 = 143.4μC

The pressure setting on a pressure-cycled ventilator will determine the pressure delivered to the patient during each breath. In pressure-cycled ventilation, the ventilator delivers a predetermined pressure to support the patient's breathing.

This pressure is maintained until a certain amount of time or a specific flow rate is reached. Once this criteria is met, the ventilator cycle ends, and the pressure drops to zero.

The pressure setting on the ventilator can be adjusted to meet the patient's specific needs. Increasing the pressure setting will deliver a higher pressure to the patient's airway, providing more support.

On the other hand, decreasing the pressure setting will deliver a lower pressure, providing less support.

It is important to note that the pressure setting should be carefully adjusted and monitored to ensure patient safety.

The appropriate pressure level should be determined by the healthcare provider based on the patient's condition, lung compliance, and other clinical factors.

Regular assessment and adjustment of the pressure setting may be necessary to optimize patient ventilation and prevent complications.

The Cold War was a rivalry between the United States and the Soviet Union, and it lasted for more than four decades. During this time, the two superpowers were engaged in a nuclear arms race.

This arms race increased tensions between the two countries and was one of the main causes of the Cold War. In this essay, we will examine how the arms race during the Cold War increased tensions.The arms race was a competition between the United States and the Soviet Union to develop more powerful nuclear weapons. Both countries wanted to have more weapons than the other, and this led to an escalation of tensions. As the United States developed more powerful weapons, the Soviet Union responded by developing its own. This led to a cycle of action and reaction that only increased tensions between the two countries.Both countries were afraid of a surprise attack from the other side. The United States was concerned that the Soviet Union would launch a first strike against them, while the Soviet Union feared the same from the United States. This fear led both countries to develop a policy of deterrence. Deterrence is the idea that a country can prevent an attack from another country by making it clear that it has the ability to retaliate with overwhelming force. The arms race made this policy of deterrence even more important because it increased the destructive power of each country's weapons.The arms race also had a psychological impact on the people of the United States and the Soviet Union. People on both sides began to fear the other country, and this fear only increased tensions. The arms race created a sense of paranoia that made it difficult for the two countries to trust each other. The fear of a surprise attack led to an arms race that only increased tensions between the United States and the Soviet Union.In conclusion, the arms race during the Cold War increased tensions between the United States and the Soviet Union. Both countries were engaged in a competition to develop more powerful nuclear weapons, and this led to a cycle of action and reaction that only increased tensions. The arms race made the policy of deterrence even more important, and it had a psychological impact on the people of both countries.
