The power produced is 712.5 W

Explanation:

First of all, we start by finding the work done by the forklift.

The work done on an object pushed in the same direction as the force is given by:

W=Fd

where

F is the magnitude of the force

d is the displacement of the object

In this problem,

F = 475 N is the force applied to raise the box

d = 18 m is the displacement

Substituting,

W=(475)(18)=8550 J

Now we can calculate the power, which is the ratio between the work done and the time taken:

P=\frac{W}{t}

Here we have,

W = 8550 J

t = 12 s

Substituting,

P=\frac{8550}{12}=712.5 W

Recall that impulse = momentum (FAt = Ap and that Ap is just mx v). How long (time) must a group of people pull with a force of
elixir [45]

The time taken for the group of people to pull the car, giving it a velocity of 1.5 m/s is 3.75 s

Momentum is simply defined as the product of mass and velocity i.e

Momentum = mass × velocity

To answer the question given, we'll begin by calculating the change in momentum. This can be obtained as follow:

Mass = 1500 Kg

Initial velocity (u) = 0 m/s

Final velocity (v) = 1.5 m/s

<h3>Change in momentum =? </h3>

Change in momentum = m(v – u)

Change in momentum = 1500 (1.5 – 0)

Change in momentum = 1500 × 1.5

<h3>Change in momentum = 2250 Kg•m/s</h3>

Finally, we shall determine the time

Change in momentum = 2250 Kg•m/s

Force (F) = 600 N

<h3>Time (t) =? </h3>

Impulse = Ft = change in momentum

FT = change in momentum

600 × t = 2250

Divide both side by 600

t = 2250 / 600

<h3>t = 3.75 s</h3>

Thus, the time required is 3.75 s

Which sequence shows electromagnetic waves arranged from shorter to longer wavelengths?. A. visible light, infrared radiation, m
joja [24]

Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.

Explanation:

Shorter wavelength means higher frequency and higher energy.

Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:

D.ultraviolet rays, visible light, infrared radiation, microwaves.

<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>

<u>Visible light has wavelength: 380 nm to 700 nm</u>

<u>Infrared wavelength: 700 nm to 1 mm</u>

<u>Microwave wavelength: 1 mm to 1 m</u>

Why am i getting so many spam calls on my cell phone.
OleMash [197]

Answer:

Why do I keep getting spam calls? Experts credit the ascendance of spam phone calls to fundamental problems with caller ID, a phone system where anyone can operate as a carrier, the inability to detect bad callers, and a number of bad actors exploiting those flaws to drive billions of calls to American phones.
