Explanation:

Energy from food can be used to make a flashlight shine by converting it into electrical energy.

When we eat food, our bodies break down the food into glucose. Glucose is a type of sugar that our bodies can use for energy. When glucose is broken down, it releases energy. This energy is used to power our cells and to do work.

One of the things that our bodies can do with energy is to convert it into electrical energy. This electrical energy can be used to power devices, such as flashlights. In a flashlight, the electrical energy from food is converted into light by a process called incandescent lighting. Incandescent lighting works by heating a filament until it glows. The filament is made of a material that gives off light when it is heated.

The electrical energy that powers the filament comes from a battery. The battery is charged by the energy from food. When we turn on the flashlight, the battery sends electrical energy to the filament. The filament heats up and glows, creating light.

Answer:

In machines that transmit only mechanical energy, the ratio of the force exerted by the machine to the force applied to the machine is known as mechanical advantage. Under mechanical advantage the distance the load will be moved will be only be a fraction of the distance through which the effort is applied.

Let Mass be m

If its doubled then

Hence force also needs to be doubled.

Answer:

I guess rinse it out and wipe it up. It's not a hazardous substance so there's nothing to worry about.

These substances should be cleaned up rinsing the area or removing the compounds with a cloth and dispose of it in the trash.

Sugar is a chemical compound also called sucrose. Its chemical formula is C12H22O11. This compound is normally used to sweeten foods.

On the other hand, common salt is a chemical compound. Its chemical formula is NaCl. This compound is normally used to give food a salty taste.

According to the above, in which a student spilled some salt and sugar in the sink and does not know how to clean it, it can be concluded that the proper way to clean these chemical compounds is by rinsing the area or removing the compounds with a cloth and dispose of it in the trash because neither of them represents biological, chemical or physical risks and a specialized treatment is not required for them.

Explanation:

the vehicles displacement, since displacement deals with position

To know the location of a vehicle that ran out of gas after taking a zigzag route through the city, the quantity that would be  most useful is the vehicle's displacement.

In physics, the term quantity refers to something that can be measured.

Displacement is a vector quantity. Displacement simply means distance covered in a specified direction.

Notice that we want to find out the location of the vehicle after it ran out of gas. In this case, we don't only need to know the distance covered by the vehicle but also the direction in which the distance was covered in order to enable us to track the vehicle.

Hence, we need to find out the vehicle's displacement.

Answer:

The correct answer is "The distance between your house and your school, and how long it took you to get there." This is the proper answer choice because mph is miles per hour. Meaning you can travel 25 miles in just one hour. Speed in such form is used for measuring distance, or time. Hope it helped.

Hi there!

Acceleration:

a = Δv / Δt, so:

a = 20/9 ≈ 2.22 m/s²

Displacement:

We can use the equation Δd = v₀t + 1/2at² to solve. (Initial velocity is 0).

Δd = 1/2at²

Plug in the acceleration and time:

Δd = 1/2(2.22)(9)² ≈ 89.91 m

Answer:

As we know 1 hc = 10000cg

now,

Her distances and displacement are;

[tex]\begin{array}{|l|c|c|}\mathbf{Location}&\mathbf{Displacement}&\mathbf{Distance}\\&&\\a. \ Quarter \ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m &375 \ m\\&&\\b. \ Half \ way \ around&\dfrac{1500}{\pi} m&750 \ m\\&& \\C. \ Three \ quarter\ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m&1,125 \ m\\&&\\d. \ Entire \ lap&0&1,500 \ m\\\end{array}\right][/tex]

The reason the above values are correct are as follows:

The known details are:

The length of the circular track, C = 1,500 m

The required details;

Her distance and displacement at four locations starting at the top of the circle, as follows;

At the top, the starting point, the displacement = The distance = 0

a. A quarter way round the track;

The radius of the circular track, r = C/(2·π)

∴ r₁ = 1,500 m/(2·π) = (750 m)/π

The displacement a quarter way round the track, s₁² = r² + r²

∴ s₁² = ((750 m)/π)² + ((750 m)/π)²

s₁ = ((750 m)/π)·√2

The displacement a quarter way round the track, s₁ = ((750·√2)/π) m

The distance a quarter way round the track, d₁ = C/4

∴ d₁ = 1,500 m/4 = 375 m

The distance a quarter way round the track, d₁ = 375 m

b. The displacement half way around the track, s₂ = r + r

∴ s₂ = r + r = (750 m)/π + (750 m)/π = (1,500 m)/π

The distance moved half way round the circular track, d₂ = C/2

∴ d₂ = 1,500 m/2 = 750 m

The distance moved half way round the circular track, d₂ = 750 m

C. The displacement 3/4 way round the track, s₃ = s₁ = (750 m)/π)·√2

The distance moved 3/4 way round the circular track, d₃ = (3/4) × 1,500 m = 1,125 m

D. The displacement for an entire lap, which is back to starting point at the TOP, s₄ = 0

The distance traveled in one lap = The circumference of the track, C = 1,500 m

Therefore, we have the following displacement and distances at the four different locations;

[tex]\begin{array}{|l|c|c|}\mathbf{Location}&\mathbf{Displacement}&\mathbf{Distance}\\&&\\a. \ Quarter \ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m &375 \ m\\&&\\b. \ Half \ way \ around&\dfrac{1500}{\pi} m&750 \ m\\&& \\C. \ Three \ quarter\ way \ around&\dfrac{750 \cdot \sqrt{2} }{\pi} m&1,125 \ m\\&&\\d. \ Entire \ lap&0&1,500 \ m\\\end{array}\right][/tex]
