What is medium definition in physics

Which of the following statements is true? 1) On a level surface, normal force equals weight. 2) The more inertia an object has, the more easily it will change its motion. 3) The more massive an object, the more quickly it will accelerate.

To enter the main pool at an amusement part, a swimmer uses a water slide which has a vertical height of 2.89 m. find her speed at the bottom of the slide if she starts with an initial speed of 0.810 m/s.

150kg object takes 1.5minutes to travel 2,500 meter straight path it begins the trip traveling 120m/s and decelerates to a velocity of 20m/s whats its acceleration

Which statement is true about the solar system

In a lab environment, you are investigating the impulse of a force exerted on a brick when the brick's speed is reduced from 2.5 m/s to a complete stop.

3. What are the challenges of looking for Dyson spheres?

Imagine you came to the lab and found a resistor with color code Blue, Red, Brown, Gold. What is the resistance of this resistor (with uncertainty). (HINT: Uncertainties should have only one significant digit and should always be rounded up)
