For two objects in space with very different masses, the gravitational force causes:
A. no net force since the equal but opposite forces cancel each other
out.
B. a force in a constant direction that acts only on the larger of the
two masses.
C. a force that makes the more-massive object orbit the less-
massive one.
D. a force that makes the less-massive object orbit the more-massive
one.

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles
