a. 290o (assuming rom = 145 o) – 0 o
b. 0 o - 290 o (assuming rom = 145 o)
c. 145 o – 0 o
d. 0 o – 145 o
e. the same

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

The least penetrating form of radiation is

Avector of magnitude 2 cannot be added to a vector of magnitude 3 so that the magnitude of the resultant is a. zero b. 1 c. 3 d. 5 e. 7
