Answer: 6s

Explanation:

Vs=32m/s  speed at beginning of slowing down

Vf=0m/s     stop speed

a= -6 m/s²  acceleration

----------------

Use equation for acceleration :

a=(Vf-Vs)/t

a*t=Vf-Vs

t=(Vf-Vs)/a

t=(0-36)/-6

t=-36/-6

t=6 s

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Below is the solution:

Output work = 108 J. 
<span>Input work = 120 J </span>

<span>Efficiency = 108/120 = 9/10 = 90% </span>

<span>(Energy can be converted to heat in friction at the fulcrum, or useless potential energy distorting the crowbar)</span>

Under ordinary conditions of temperature and pressure, the particles in a gas are Select one: a. closely packed. b. very far fro
klemol [59]

Answer:

The particle of a gas are very far apart from each other.

Explanation:

The states of matter comprises of solid, liquid and gas. The molecules of gas are free because they are not tightly held together by molecular force. The force between the molecules has been broken, hence the particles possesses the freedom to move about thereby possessing high kinetic energy (energy possessed by a body due to its motion). Since this molecules can easily move freely, they are always far apart from each other under ordinary temperature and pressure.

When u step on the brakes what energy transformation takes place describe the transformation
larisa [96]
Before you step on the brakes, the car has kinetic energy, when you step on the brakes, it turns the kinetic energy into heat (thermal energy). When it stops completely, it has potential energy. Hope this helped :)

A grating has 470 lines/mm. how many orders of the visible wavelength 538 nm can it produce in addition to the m = 0 order?
Natali [406]

Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.

The ruling separation is d=1/(470mm-1)

= 2.1 \times 10 {}^{ - 3}mm

Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.

Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.

we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.

That is,find the greater integer value of m for which mλ<d.

since,d/λ

= 538 \times 10 {}^{ - 9} m/2.1 \times 10 {}^{ - 6}

There are three complete orders on each side of the m=0 order.

The second and third orders overlap.
