Explanation:

Given parameters:

Mass of rock  = 0.22kg

Initial velocity  = 20m/s

Distance moved  = 10m

Unknown:

Initial kinetic energy of the rock  = ?

Solution:

To solve this problem, we need to understand that kinetic energy is the energy due to the motion of a body.

It is mathematically expressed as;

     Kinetic energy  = \(\frac{1}{2}\) m v²

m is the mass

v is the velocity

   Kinetic energy  =  \(\frac{1}{2}\) x 0.22 x 20²   = 44J

The minimum temperature is found to be approximately 72.4 °C obtained using the Carnot efficiency equation.

The efficiency of an ideal heat engine operating between two reservoirs can be determined using the Carnot efficiency formula:

Efficiency = 1 - (T_cold / T_hot)

Where T_cold is the temperature of the cold reservoir (ambient temperature) and T_hot is the temperature of the hot reservoir.

To find the minimum temperature of the hot heat reservoir, we need to solve for T_hot. Rearranging the Carnot efficiency equation, we have:

T_hot = T_cold / (1 - Efficiency)

Substituting the given values, T_cold = 35.0 °C and Efficiency = 0.462, we get:T_hot = 35.0 / (1 - 0.462)

Calculating this expression, we find that the minimum temperature of the hot heat reservoir should be approximately 72.4 °C.

Therefore, in order to achieve at least 46.2 percent efficiency with the heat engine in an environment where the ambient temperature is 35.0 °C, the minimum temperature of the hot heat reservoir should be around 72.4 °C.

The outside pressure has increased the same amount as the inside pressure.

When the internal pressure of a balloon increases but the balloon does not change in size, it implies that the external pressure acting on the balloon must have increased by the same amount as the internal pressure. This balance of pressures prevents the balloon from expanding or contracting.

By Newton's third law of motion, for every action, there is an equal and opposite reaction. In the case of the balloon, the increase in internal pressure exerts a force on the walls of the balloon. The external pressure must match this force to maintain equilibrium and prevent any change in the size of the balloon.

Answer: Different types of fuels have varying compositions and release different amounts of pollutants when burned. Here are some common types of fuels and the pollutants associated with them:

Fossil Fuels:

a. Coal: When burned, coal releases pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

b. Petroleum (Oil): Burning petroleum-based fuels like gasoline and diesel produces CO2, SO2, NOx, volatile organic compounds (VOCs), and PM.

Natural Gas:

Natural gas, which primarily consists of methane (CH4), is considered a cleaner-burning fuel compared to coal and oil. It releases lower amounts of CO2, SO2, NOx, VOCs, and PM.

Biofuels:

Biofuels are derived from renewable sources such as plants and agricultural waste. Their environmental impact depends on the specific type of biofuel. For example:

a. Ethanol: Produced from crops like corn or sugarcane, burning ethanol emits CO2 but generally releases fewer pollutants than fossil fuels.

b. Biodiesel: Made from vegetable oils or animal fats, biodiesel produces lower levels of CO2, SO2, and PM compared to petroleum-based diesel.

Renewable Energy Sources:

Renewable energy sources like solar, wind, and hydropower do not produce pollutants during electricity generation. However, the manufacturing, installation, and maintenance of renewable energy infrastructure can have environmental impacts.

It's important to note that the environmental impact of a fuel also depends on factors such as combustion technology, fuel efficiency, and emission control measures. Additionally, advancements in clean technologies and the use of emission controls can help mitigate the environmental impact of burning fuels.

Work = Force X Distance

A swimmer cannot go forward while wearing a drag suit because it creates more pressure and friction with the water than a racing suit does, and the swimmer must use more power to get past it.

As a swimmer becomes accustomed to exerting more force, his or her muscles work out and help build strength.

Drag, lift, gravity, and buoyancy are the forces at play. The primary propelling forces that swimmers employ are lift and drag. Drag, often known as resistance, can be divided into three primary groups: eddy resistance, skin friction, and frontal resistance.

Answer:

the final velocity of the car is 59.33 m/s [N]

Explanation:

Given;

acceleration of the car, a = 13 m/s²

initial velocity of the car, u = 120 km/h = 33.33 m/s

duration of the car motion, t = 2 s

The final velocity of the car in the same direction is calculated as follows;

v = u + at

where;

v is the final velocity of the car

v = 33.33 + (13 x 2)

v = 59.33 m/s [N]

Therefore, the final velocity of the car is 59.33 m/s [N]

Answer:

B. A large current forms, drops to zero, then a smaller current forms in the opposite direction

Explanation:

The results of Lionel observation about electromagnetic induction is as follows:

In the first step, a large current will form because of the fast or quick movement of the magnet into the right end of a solenoid that generates a  induces emf.

In the second step, the magnet was in rest position for 3 s so the current drops to zero because according to Faraday's law, no voltage will be generated if the magnet held stationary and no voltage means no current.

In the third step, smaller current forms in the opposite direction as the magnet is slowly moving away from the solenoid generating a smaller voltage.

Hence, the correct answer is "B."

A. Rock cycle

Explanation:

Because it really is the change of a rock from another, like ingenuous, sedimentary rock..

Answer:

1/2 m v^2 = G M m / R         speed of object at surface of earth

v^2 = 2 G M / R        escape speed needed

V = 3 v     if original speed = 3 * escape speed

v^2 / 9 = 2 G M / R

v^2 = 18 G M / R    where v is initial speed

v^2 = G M / R  * (18 - 2) = 16 G M / R     very far from earth

v = (16 G M / R)^1/2

v = (16 * 6.67E-11 * 5.98E24 / 6.37E6)^1/2

v = 31650 m/s = 19.7 mi/sec

When a particle is projected from the surface of Earth with a speed equal to 3 times the escape speed, its final speed when very far from Earth will be 2 times the escape speed.

The escape speed is the minimum speed required for an object to overcome Earth's gravitational pull and move indefinitely away from it.

When a particle is projected with a speed 3 times the escape speed, it has more than enough energy to escape Earth's gravity.

As the particle moves away from Earth, it loses some of its kinetic energy due to Earth's gravitational force. Eventually, when the particle is very far from Earth, it will have lost an amount of kinetic energy equal to the escape speed.

Summary: When a particle is projected with a speed 3 times the escape speed and reaches a point very far from Earth, its speed will be 2 times the escape speed.

The average emf induced in the coil is 0. 533 V. The average emf induced in the coil can be calculated using Faraday's law of electromagnetic induction. The formula for the average emf induced in a coil is given by:

E = N * (ΔΦ / Δt)

where E is the average emf, N is the number of turns in the coil, ΔΦ is the change in magnetic flux, and Δt is the time interval.

In this case, the number of turns is 80, and the time interval is 0.0600 s. The change in magnetic flux can be calculated by finding the initial and final flux values.

The initial flux is given by Φ1 = B * A * cos(θ1), where B is the magnetic field, A is the area of the coil, and θ1 is the angle between the coil and the magnetic field.

The final flux is given by Φ2 = B * A * cos(θ2), where θ2 is 90 degrees since the coil is perpendicular to the field.

Substituting the values into the formula, we have:

\(E = 80 * (Φ2 - Φ1) / Δt\)

Calculating the values, we find:

\(Φ1 = (1.10 T) * (0.25 m) * (0.40 m) * cos(37.0°) = 0.536 WbΦ2 = (1.10 T) * (0.25 m) * (0.40 m) * cos(90°) = 0.110 WbΔΦ = Φ2 - Φ1 = 0.110 Wb - 0.536 Wb = -0.426 Wb\)

Substituting the values into the formula, we get:

E = 80 * (-0.426 Wb) / 0.0600 s = -0.568 V

Taking the absolute value, the average emf induced in the coil is 0.568 V or approximately 0.533 V.
