What's the formula to torque?

Answers

Answer 1

Answer: The formula of torque is T=FR (T is torque, F is force, R is radius)

Answer 2

Answer: so the formula would be F times R for torgue

What is the power of 10 when 0.000028 is written in scientific notation

Answers

For this case, the first thing we must do is define the scientific notation.

We have then:

Scientific notation is a way of writing numbers too big or small in a conventional way.

A number written in scientific notation has the following form:

Where,

m: it is called matinsa

e: it is the order of magnitude

Therefore, for the given number we have that the scientific notation is:

Answer:

the power of 10 when 0.000028 is written in scientific notation is:

-5

2.8x10 to the power of -5

A disk-shaped space station 175 m in diameter spins uniformly about an axis perpendicular to the plane of the disk through its center. How many rpm (rev/min) must this disk make so that the acceleration of all points on its rim is g/2?

Answers

The angular velocity of the disk must be 2.25 rpm

Explanation:

The centripetal acceleration of an object in circular motion is given by

$a=\omega^2 r$

where

$\omega$ is the angular velocity

r is the distance of the object from the axis of rotation

For the space station in this problem, we have

$a=(g)/(2)=(9.8)/(2)=4.9 m/s^2$ is the centripetal acceleration

The diameter of the disk is

d = 175 m

So the radius is

$r=(175)/(2)=87.5 m$

So, a point on the rim has a distance of 87.5 m from the axis of rotation. Therefore, we can re-arrange the previous equation to find the angular velocity:

$\omega = \sqrt{(a)/(r)}=\sqrt{(4.9)/(87.5)}=0.237 rad/s$

And this is the angular velocity of any point along the disk. Converting into rpm,

$\omega=0.236 (rad)/(s)\cdot (60 s/min)/(2\pi rad/rev)=2.25 rpm$

Lisa exposes an iron paper clip to a very strong magnet. She is now able to pick up other paper clips using her newly magnetized clip. What happens within the paper clip in order for it to become magnetized?A) The magnet randomizes the domains within the paper clip.

B) Part of the strong magnet "rubs" off and joins to the paper clip.

C) The strong magnet aligns the magnetic domains within the paper clip.

D) The strong magnet creates an electric force filed around the paper clip.

Answers

When Lisa exposes an iron paper clip to a very strong magnet, the strong magnet aligns the magnetic domains within the paper clip and so, she is now able to pick up other paper clips using her newly magnetized clip.

What is magnet?

The ends of the magnet, which are referred to as the poles, attract all of the iron filings when a small amount of it comes into contact with them. A magnet has two poles: an opposite pole and a similar pole. While unlike poles attract, like poles repel. When the distance between the two magnets is smaller, the magnetic force between them is larger.

Three different kinds of magnets exist:

Permanent magnet
Temporary magnet
Electromagnets

Magnets are created when ferromagnetic elements, such as iron and nickel, are subjected to a magnetic field. Metals become permanently magnetic when heated to specific temperatures.
