Answer:

1st t=d/s

2nd s=d/t

5th d=st

are all of the variations I came up with

Explanation:

the original formula for speed is s=d/t

then, I created a ratio of s/1=d/t and cross multiplied to find d=st

then, I isolated the t in one side by dividing by s on both sides.

Answer:

S = d/t

Explanation:

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time.

A student is modeling electric forces and potential energy in a system with two opposite charges. For his model, he uses a rubber band with a marble attached to either end. When the rubber band is stretched, does the model predict what will happen to the force and potential energy in the system? Explain.

If a machine decreases the distance an object moves, it must also _____.
increase the object's acceleration
decrease the force used to move the object
decrease the object's mass
increase the force used to move the object

Drag each label to the correct location on the image.

Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above the ground and lets it go. The image shows Jessica at three positions on the swing. Jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. What’s the energy she has at each position shown? Ignore friction and air resistance.

This chart lists four examples of two objects that are in contact.

A 3-column table with 4 rows. The first column has entries Example 1, Example 2, Example 3, Example 4. The second column labeled Object 1 has entries fire, a metal at 80 degrees Celsius, the cool ocean, a tool with a lot of thermal energy. The third column labeled Object 2 has entries air, a metal at 12 degrees Celsius, the warm air, a material with little thermal energy.

Which statement accurately describes the flow of heat in each example?

Heat will flow from Object 1 to Object 2 in examples 2 and 4, and heat will flow from Object 2 to Object 1 in examples 1 and 3.
Heat will flow from Object 1 to Object 2 in examples 1 and 3, and heat will flow from Object 2 to Object 1 in examples 2 and 4.
Heat will flow from Object 1 to Object 2 in Example 3, and heat will flow from Object 2 to Object 1 in examples 1, 2, and 4.
Heat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3.

Mintu wants to increase the heat transfer between a metal iron and another piece of metal he wants to shape. He decides to increase the time the two metals are in contact, use a larger metal iron, and use a new metal material with a higher specific heat.

Where is Mintu's error?

Mintu should have decreased the size of the metal iron.
Mintu should have decreased the time he touches the two metals.
Mintu should have chosen a material with a lower specific heat.
Mintu should have chosen a material the same temperature as the iron.
