A205 kg log is pulled up a ramp by means of a rope that
isparallel to the surface of the ramp. the ramp is inclined at30%
with respect to the horizontal. the coeffecient ofkinetic frictin
between the log and the ramp is 0.900 and the loghas an
acceleration of 0.800 m/s2. find the tension in therope.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
