A fan has 2000 J of kinetic energy. If the angular velocity of the fan is doubled,
DanielleElmas [232]

The new Kinetic energy is 8000 J

Step-by-step explanation:

Step 1 :

Given,

The Kinetic energy of the fan = 2000J

We need to find  new kinetic energy when the angular velocity is doubled.

Step 2 :

We have

KE = \frac{1}{2 } × m × v² = 2000

where m represents the mass and  v represents the singular velocity

v = r ω where

r is radius of  fan and ω is the angular velocity.

Given that the angular velocity is doubled  singular velocity is also doubled. since the radius of the fan is the same in both cases we have

the new velocity = 2rω = 2v

So the KE = \frac{1}{2} m(new velocity)² = \frac{1}{2} m(2v)² = 4 (\frac{1}{2} mv²) = 4 (2000) = 8000 J

Step 3 :

Answer :

The new Kinetic energy is 8000 J

100 points t who answers first and if answered right u will get brainiest ok
Grace [21]

Answer:

side c = 150 feet of flowers

Area = 5400 feet squared

concert question:

The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle

Concession stand question:

The school banner can fit across the length of the concession stand

the following information is missing

The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.

The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:

diagonal² = 30² + 30²

diagonal = √1800  = 42.43 ft

which is longer than the banner.

Blueprint question:

No, diagonal of square C is 70.71ft

2nd blueprint question:

50 square root 2

Gardening group:

50.24 yards

Which of the following equations represents the area of a sector?
Rina8888 [55]

From the given options we can say that the only one that represents the area of the sector is; A = n/360 * πr²

<h3>What is the Area of the Sector?</h3>

In circles, a sector is said to be a part of a circle made of the arc of the circle together with its two radii. This means that it is a portion of the circle formed by a portion of the circumference (arc) and radii of the circle at both endpoints of the arc.

The formula for Area of a sector is given as;

θ/360 * πr²

where;

θ is the central angle of the sector

r is radius

Now, looking at the given options we can say that the only one that represents the area of the sector is;

A = n/360 * πr²

where n is the central angle of the sector
