Explain why the

ball looks red

under normal

light.

Which condition must exist in order for conduction to occur between two substances

Ikg. Refer to your lab guide and review the data in Table F to complete each statement. The mass of G1 at all times during this trial was The velocity of G1 + G2 after the collision was m/s. The momentum of G1 after the collision was kg. m/s.

a 1500.0 kg car is at rest on a level track. The driver gives the engine gas and the car begins to accelerate forward. The car moves from 0 m/s to 27 m/s in 8 s. What is the acceleration of the car. What is the force of the car moving forward?

Which of the following would have the most potential energy? A. a car moving along a flat road at 60 mph В. a rollercoaster that is at the bottom of a hill C. a ball rolling on a flat surface D. a rock sitting on the edge of a cliff

An inclined plane of angle θ has a spring of force constant k fastened securely at the bottom so that the spring is parallel to the surface. A block of mass m is placed on the plane at a distance d from the spring.

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.

A set of data is collected from a simple circuit with a 20 resistor and is represented in the table

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. a.

8. What happens to force when mass is increased?

Give an example of ionic and covalent bond, and explain and make an example for each.
