I'm having trouble figuring out how to study for my science test, it's based off of everything we've learned but I'm afraid there's some things I misunderstood during the year that will effect me on the test, and suggestions?!!

A drag car takes off at the green light in a straight line. The car from 45 m/s to a complete stop in 9 seconds. What is its acceleration? Was it positive or negative?

They are adding steel components to the roof supports of the structure. We know that steel elongates when heated. At what temperature will steel elongate nine inches per 100 feet of length? a) 500 degrees. b) 1000 degrees. c) 1500 degrees.

3 example of conductors

Work out the kinetic energy of a 2.5 kg remote-controlled car that is moving at 2 m/s.

Two motorcycles are traveling due east with different velocities. However, four seconds later, they have the same velocity. During this four-second interval, cycle A has an average acceleration of 1.

Will make Brainlest! <3 Metals are considered to be good conductors of heat. How do the specific heat values indicate this?

Which example identifies a change in motion that produces acceleration? choices are: 1. a speed skater moving at a constant speed on a straight track 2. a ball moving at a constant speed around a circular track 3.

Which of the following diagnostic procedures uses ultrasound?

Why is it easier to read black text on a white background than to read green text of any light color?

If object A has more mass than object B, does object A contain more matter? Explain.
