15 points! Middle School Physical Science.

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.

This question is about magnets and net force (I think.) Please no absurd answers!

Please check my answers.

A student made the table shown to list some contact and non-contact forces.


Examples of Forces
Contact Forces Non-Contact Forces
The force exerted by a stretched spring The force applied by Earth and sun on each other
The electrical force exerted by a positive charge on a negative charge Magnetic attraction between two magnets


Which statement best explains why the table is incorrect?
Spring force is a force acting at a distance.
Electrical force is not a contact force.
Gravitational force can act between planets and sun only when they are in contact.
Magnetic attraction is a contact force

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.
