Abaseball is hit at an initial speed of 40 m/s at an angle of 60° above the horizontal. the ball flies for 10 s. find the distance, in meters, that the ball travels. use g = 9.81 m/s2. a) 100 m b) 146 m c) 200 m d) 346 m

The mini-refrigerator fire was most likely caused by what type of wiring?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

What are similarities and differences between refraction, reflection, diffraction and absorption?
