Roberto was testing how light interacted with a material he had just developed. The initial speed of light was
3.0 x 108 m/s. The final speed of light after it changed direction was 1.7 x 108 m/s.
What type of interaction took place?

True or false a high force means an object is moving fast100 points!

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false
