Mass is density times volume
0.760 x 531 = 403.56g
404g if 3 sig figs
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
Force causes all motion, and the larger the mass of an object the stronger the force needs to be to accelerate the object.
Answer:
Choice B
They are polar climates because they are dry
and cold
