A: Measuring the distance between objects in the ocean

Explanation:

The sound waves produced by the engine have a frequency of 120 Hz.

To calculate the frequency of the sound waves produced by the engine, we can use the following formula:

f = 1/T

where f is the frequency and T is the period of the sound wave.

Sound waves have a period of 8.3 milliseconds, so we can plug this value into the equation to find the frequency.

f = 1 / (8.3 x 10^-3s)

f = 120 hertz

Therefore, the sound waves produced by the engine have a frequency of 120 Hz.

It is important to note that frequency is the number of wave oscillations or cycles that occur in a unit of time and is measured in hertz (Hz). The period is the time of one oscillation and is the reciprocal of the frequency. The lower the frequency, the longer the period and vice versa.

Pressure acts in all direction .

What is the fundamental meaning of pressure?

The amount of force applied to a unit area is referred to as pressure. The weight of the water column above contributes to the pressure in a liquid. This pressure works in all directions because a liquid's particles are closely packed. For instance, the pressure exerted on a dam at a reservoir's bottom is larger than the pressure exerted near the top.

There is a magnitude to pressure, but no accompanying direction. At one location inside a gas, pressure spreads out in all directions. The pressure force acts perpendicular to the surface at a gas's surface.

7.2 gallons of oil is needed to generate the electricity needed to keep 100-watt light bulb lit for one year if the overall efficiency of generating station is 30%.

Ratio of the work performed by machine or in process to the total energy expended / heat consumed is called as efficiency.

Energy consumed is 100 W * 8760 h = 876,000 Wh = 876 kWh.

Given, overall efficiency of the generating station is 30%, which means that only 30% of energy in the fuel is converted into usable electricity. So, for every 1 unit of energy in fuel, 0.3 units of energy are generated as electricity.

To find out how much oil is needed, we need to divide total energy consumed by the light bulb (876 kWh) by the overall efficiency of the generating station (0.3). So, 876 kWh / 0.3 = 2920 kWh

Now we need to convert the energy consumption in kWh to gallons of oil,

2920 kWh = 2920 * 3412 Btu/kWh = 1,000,944 Btu

1,000,944 Btu / 138,690 Btu/gal = 7.2 gallons

Therefore, 7.2 gallons of oil is needed to generate the electricity needed to keep 100-watt light bulb lit for one year.

The resistance of two resistors are R1 is and R2 is 1.4ohms and 6.2ohms respectively where R1 is smaller and R2 is larger resistance.

Given the voltage of battery (V) = 12V

Let the resistance of smaller resistor = R1

Let the resistance of larger resistor = R2

The current in circuit when connected in parallel (Is) = 1.57A

Ohms law states that V = IR where V is voltage R is resistance and I is current.

When resistors are connected in series Rs = R1 + R2

V =Is(R1 + R2)

R1 + R2 = 12/1.57 = 7.6

R1 = 7.6 - R2

When resistors are connected in parallel 1/Rp = 1/R1 + 1/R2

then Rp = R1R2/R1 + R2

The current in parallel circuit (Ip) = 10.5A

V = Ip(R1R2/R1+R2)

R1R2 = 12 x (7.6) / 10.5 = 8.68

(7.6 - R2)R2 = 8.68

R2^2-7.6R2+8.68 = 0

R2 = 6.2ohm

R1 = 7.6 - 6.2 = 1.4ohms

The two appropriate factors that can assist in determining air pressure are wind, speed and air temperature. The appropriate choices are A) and C).

Everything you touch is pressed upon by the weighty air that surrounds you. The term air pressure or atmospheric pressure is used to describe this pressure. When a surface is being pulled toward Earth by gravity, air above the surface exerts a force on it. It is common practise to measure atmospheric pressure using a barometer.

Because air pressure is determined by the quantity of molecules above a surface, this is the case. It's interesting to note that as the number of molecules grow, more pressure is applied to a surface, increasing the overall air pressure. In contrast, when the number of molecules falls, the air pressure rises.

The average kinetic energy of the gas's molecules directly relates to its temperature. Faster moving particles will more frequently and violently hit with the container walls.

To determine the speed at which the baseball player threw the ball and the height it reached, we can use the equations for motion with constant acceleration. So hence  t is the time it took for the ball to return to the player's hand.

Since the ball was thrown vertically upward and we know the time it took for it to return to the player's hand, we can use the following equation to determine the initial velocity (vₒ) of the ball: vₒ = gt . where g is the acceleration due to gravity (approximately 9.8 m/s²) and t is the time it took for the ball to return to the player's hand (3.0 s).

Plugging in the known values, we get:

vₒ = 9.8 m/s² x 3.0 s = 29.4 m/s

To determine the height the ball reached, we can use the following equation: h = vₒt + (1/2)gt²

Electrons from the charged object as conduction are the charging by contact

Conduction is indeed a method of charging by contact. In conduction, charges are transferred between two objects that are in contact with each other. When an uncharged object comes into contact with a charged object, electrons will flow from the charged object to the uncharged object, until both objects have the same charge.

In solids, conduction occurs when electrons flow through the material, moving from atom to atom. Metals, such as copper and aluminum, are good conductors of electricity because their electrons are not tightly bound to their atoms and can easily flow through the material. Insulators, such as rubber and plastic, are poor conductors of electricity because their electrons are tightly bound to their atoms and do not flow easily through the material.

The ball drops quicker as a result of the topspin, which might make it more challenging for the opponent to strike the ball at the appropriate moment. Topspin may be used to produce shots that are more difficult to return because of this.

Generally, The Magnus effect is caused by the difference in air pressure on the top and bottom of a spinning object.

On a ball with a topspin, the air pressure is greater on the top of the ball than on the bottom, which creates a lifting force that causes the ball to move upward.

This can cause the ball to have more height or to curve in a specific direction, making it more difficult for the opponent to return.

The topspin also causes the ball to drop faster than it would otherwise, which can make it more difficult for the opponent to hit the ball at the right time. This makes topspin a useful tool for making shots that are harder to return.

No. Perhaps the best remedy for a flooded engine is time. Simply open the hood of your car and let excessive fuel evaporate for as long as you can. After about 20 minutes try starting your car again without hitting the gas pedal. If this still does not work, you may have to check your spark plugs.

Why won’t your car start. It turns over, so there’s no problem with the battery, but it won’t fire. Chances are, if you've just started it, moved it a few metres and shut it off again, you've flooded the engine – this is really common as we sometimes want to move a car under the car port, into some shade or into a better parking spot, but without driving it any more than a few metres.

Flooding the engine has nothing to do with water, but the amount of fuel that’s been introduced into the engine. It rarely happens with modern, fuel-injected cars if the temperatures are normal. If it’s cold or very hot it can happen, too.

Don’t keep letting it turn over because you’ll wear out the battery and you’re making the flooding worse (so much so, that you might have so much petrol in the cylinders that it seeps into the oil). Also, don’t pump the accelerator as this can make the flooding worse.

Length is a measurement of distance or size. It is commonly used to describe the linear extent of an object, such as the size of a room, the length of a river, or the size of a person. It can also be used to describe the duration of an event, such as the length of a movie or the length of a football game. Length is typically measured in units such as meters, feet, or inches.

The power at the receiver can be calculated using the formula:

P_r = P_i * 10^(-α*L/10)

where P_r is the power at the receiver, P_i is the input power, α is the attenuation per unit length and L is the length of the fiber.

Rearranging the formula, we obtain:
