A 0.40 kg mass attached to an ideal spring oscillates horizontally with a period of 0.50 s and amplitude of 0.20 m.
What is the spring constant of the spring?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

The energy produced as a result of this flow of electrons from atom to atom is called
