A 15.0 kg box is being pulled along level ground by a 75.0 N force that is directed at an angle of 200 above the horizontal. The coefficient of kinetic friction is 0.330. What is the acceleration of the box?

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

Which features on mars point to the possibility of liquid water on the planet? impact craters with sharp rims volcanic cones with craters gullies and stream-like channels mountain ranges with faults

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
