One end of a rope is tied to a block of mass 3.4 kg and you pull straight up on the other end of the rope to lift the block up off of the ground with an acceleration of 3.6 m/s2. What force (in N) does the rope exert on the block

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
