Two students make a model of a tree house they want to build. The sale is 1:44. In the scale model, the tree house has 2 windows. How many windows should be the real tree house have?
A. 22
B. 88
C. 4
D. 2

Answers

Answer 1
D. 2

The scale is talking about how if on the model it states the wall is 1 foot you would make it 44 feet The windows and doors are just there to make sure you don’t forget them. Hope this helped! :D

List three examples of where potential energy is transformed to kinetic energy in the Rube Goldberg Machine simulation. Fully explain the energy transformations using complete sentences. (Example: The ball has potential energy when it sits on the shelf that transforms to kinetic energy when it falls to the ground.)

DO NOT COPY AND PAST THE ANSWER FROM 2018 AND IF YOU HAVE A QUSTOIN ABOUT IT ASK UNDER THE QUSTION DO NOT ANSWER IT TO ASK A QUSTION

Answers

Answer:

1. The ball will have potential energy at the top of the mountain, when the ball falls the ball will have kinetic energy .

2. The roller coaster has potential energy when stopped on the very top, therefore it releases kinetic energy when it falls down the rollercoaster.

3. The car on the hill had potential energy weather when it went down it had kinetic energy.

Where does the force come from when a bumper car changes speed?

Answers

Answer:

Newton's second law

Explanation:

The rate of change of momentum of an object is equal to the net force acting on it. When bumper cars collide they push on each other. These pushes cause the momentum of each car to change.
