6. A girl is riding her skateboard down a hill. She speeds up as she goes down the hill, and the wheels get a little warmer. Saved to this PC What energy transformations happen while she is going down the hill?
A. Motion energy (kinetic energy) is transformed into gravitational potential energy an thermal energy
B. Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy. C. Gravitational potential energy is transformed only into motion energy (klnetic energy).
D. No energy transformations are involved while she is going down the hi D​

Answers

Answer 1

Answer:

B

Explanation:

the wheels are getting warmer so it would have to be thermal energy, hope this helps :)

Answer 2

Gravitational potential energy is transformed into motion energy ,kinetic energy and thermal energy.

We know that Gravitational potential energy is the potential energy with respect to the gravitational force. To possess gravitational potential energy, the object to be placed in a position in the gravitational field.

What is potential energy?

Potential energy of body is the energy generated by virtue of the position of the body. Whereas kinetic energy is generated by virtue of its movement.

Potential energy and kinetic energy together called as mechanical energy. The potential energy is mathematically expressed as;

p = mgh.

Here, g s gravity, h is height and m is the mass.

The gravitational potential energy can be arised in an object due the position in gravitational field. That changes with the change in position and change in height from the ground.

Hence Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy.

Step-by-step explanation:

Answer:

90 PO ANG SAGOT!!!!!!!!!!!!!!!!!!!

(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.

Write and solve an equation to determine the measure of angle y.

Answers

☁️My Answer☁️:

y = 90°

✧My Step-by-step explanation✧:

The angle x forms a straight line with the both the 50° angle and the 40° angle:

x + 50° + 40° = 180°

x = 90°

Which means…

y = x = 90°

A chess piece is 15 centimeters tall, and its shadow is 13 centimeters long. How far away is the top of the chess piece from the end of its shadow? Round to the nearest tenth.

Answers

Answer:

19.8 cm

Step-by-step explanation:

Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

Which expression is equivalent to 12 x + 3 ( x − 2 )

Answers

Answer:

15x - 6

Step-by-step explanation:

To solve this, Given the expression 12 x + 3 ( x − 2 )

To simplify, expand

12 x + 3 * x −3 * 2

Knowing that

- * + = -

then the expression becomes

= 12 x + 3x - 6

= 15x - 6

The expression given is equivalent to 15x - 6

Answer: x = 1 and y = 2

Step-by-step explanation:

Solve for y in the first equation by adding 2x to both sides

[tex]y=2x[/tex]

Plug this answer into the y for the second equation

[tex]3x+4(2x)=11[/tex]

Combine like terms and simplify

[tex]3x+8x=11\\11x=11\\x=1[/tex]

Now solve for the y value by plugging in x to any equation

[tex]y=2x\\y=2(1)\\y=2[/tex]

Solve the equation:
8b = 5.6

Answers

Answer:

b = 0.7

Step-by-step explanation:

to solve the equation, you must isolate "b" so the variable is by itself,,

to do this, divide both sides of the equation by 8:

8b = 5.6

b = 5.6/8

now, simply divide 5.6 by 8 to get your answer,,

b = 5.6/8

b = 0.7

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.

Answers

Answer:

8 inches

Step-by-step explanation:

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf

Step 1

The amount of board he used to build the shelf is calculated as:

= 3/4 of 8 foot board

= 3/4 × 8 foot

= 6 foot board.

Step 2

The amount of board left after building the shelf = The rest =

8 foot - 6 foot

= 2 foot

Step 3

We are told that he gave 1/3 of the rest to his brother for an art project

The amount of board he give his brother for an art project =

1/3 × 2 foot

= 2/3 foot

Step 4

How many inches was the piece Anthony gave to his brother?

We convert 2/3 foot to inches

1 foot = 12 inches

2/3 foot = x inches

Cross Multiply

x inches = 2/3 foot × 12 inches

x inches = 8 inches

Therefore, Anthony gave his brother 8 inches of board.
