Answer:

Hello There!!

Explanation:

You use the formula:K.E. = 1/2 m v2.

kinetic energy=1 / 2 × 10 × 5 ²(the power of 2 means you multiply the number by itself)

half of 10 is 5 so you do 5×5².

kinetic energy=5×5²=(5×5=25) so 25×5=125 Joules.

hope this helps,have a great day!!

Answer:

kinetic energy = 1 / 2 mv²

kinetic energy = 1 / 2 × 10 × 5 ²

kinetic energy = 5 × 25

kinetic energy = 125 joules

Answer:

25.13 cm

Explanation:

Mrs. Lynn's art class is making pencil holders out of soup cans

These soup cans are definitely in cylindrical forms.

Each student is first covering a can with felt.

A felt is a type of material that is used for covering other objects. Here a felt is used to cover soup cans.

So if the diameter of the bottom of the can is 8 cm (i.e d = 8cm)

What will the circumference of the piece of felt need to be in order to cover the bottom of the can?

The felt will also take the circumference of a cylinder; and which is given by the expression

C = 2 πr

since diameter (d) = 8 cm

radius (r) = \frac{d}{2}

r = \frac{8}{2}

r = 4 cm

C = 2 × π × 4 cm

C = 2 × 3.142 × 4 cm

C = 25.13 cm

∴ the circumference of the piece of felt need to be 25.13 cm in order to cover the bottom of the can.

Which phrases describe all the outer planets’ motion? Check all that apply.
uranmaximum [27]

Answer: slow revolution and fast rotation

Solar system has 8 planets. 4 inner rocky planets - Mercury, Venus, Earth and Mars and 4 outer gaseous planets - <u>Jupiter, Saturn, Uranus and Neptune.</u>  The outer planets have few common features.

They are gaseous. There  period of revolution is larger than the inner planets which means that they have slow revolution about the Sun. One day on the outer planets is smaller than the inner planets which means they have fast rotation.

<u>For example,</u> Jupiter has revolves around sun in 11.86 Earth years and rotates about axis in 9.8 Earth hours. Uranus revolves around sun in 84 Earth years and rotates on its axis 17.9 Earth hours.
