Answer:

(c) position

Explanation:

From the work-energy theorem, the workdone by a force on a body causes a change in kinetic energy of the body.

But, remember that the work done (W) by a force (F) on a body is the product of the force and the distance d, moved by the body caused by the force. i.e

W = F x d

This distance is a measure of the position of the body at a given instance.

Therefore, the work done is given by the force as a function of distance (or position).

Ultraviolet (UV) radiation can be subdivided into three regions: UVA, UVB, and UVC, based on their energy. What are the minimum
ruslelena [56]

Answer:

100nm-280nm

Explanation:

Ultraviolet rays (UV) are part of the electromagnetic spectrum. It goes from 10nm to 400nm wavelengths, they are shorter than visible light, thus it's impossible to see by a human eye, and larger than X-rays (used in many medical applications and harmful when long-exposed).

According to its wavelengths, UV can be divided in different types:

UVA: long wave UV (315nm-400nm)

UVB: medium-wave UV (280nm-315nm)

UVC: short wave UV (100nm-280nm)

Therefore, UVC comprises wavelengths between 10nm and 280nm.

A Ferris wheel at a carnival has a diameter of 58 feet. Suppose a passenger is traveling at 9 miles per hour. (A useful fact: .)
Anastasy [175]

Answer:

a) 27.2 rad/min

b) 260 rev/h

Explanation:

The passenger is traveling at 9 mph, this is the tangential speed.

The relation between tangential speed and angular speed is:

v = r * w

Where

v: tangential speed

r: radius

w: angular speed

Also, the radius is

r = d/2

d is the diameter

Therefore:

v = (d * w)/2

Rearranging:

w = 2*v/d

w = (2*9 mile/h)/(58 feet)

We need to convert the feet to miles

w = (2*9 mile/h)/(0.011 miles) = 1636 rad/h

We divide this by 60 to get it in radians per minute

w = 1636/60 = 27.2 rad/min

Now the angular speed is in radians, to get revolutions we have to divide by 2π

n = v/(π*d)

n = (9 mile/h)/(π*0.011 mile) = 260 rev/h
