Newton's second law says force (f) is equal to mass (m) times acceration (a). a scientist wants to calculate the force of an object where the acceleration of gravity (g) is 9.8 m/s2. use the function to calculate the force for an object with a mass (m) of 0.29 kilograms.
a) 9.51 newtons
b) 0.029 newtons
c) 34 newtons
d) 2.8 newtons

Which statement correctly describes a step-up transformer? a. it increases the amount of electric energy available. b. it increases the voltage of an electric current. c. it changes direct current into alternating current. d. it has more loops of wire in its primary coil.

What is a carrier wave and how does it affect what you hear on the radio

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
