On each given day and location, tides rise and fall at

behind at satellite speed

To drop a package to Earth from a satellite, project it

Moon

Which is most responsible for Earth's ocean tides?

less than 50 m/s.

A projectile is launched vertically upward at 50 m/s. If air resistance does affect motion, then its speed upon returning to its starting point is

greater the gravitational force between them.

According to Newton, the greater the masses of interacting objects, the

none of the above

All places on Earth would have high tides at the same instant if the

extra high

During an eclipse of the Sun the high ocean tides on Earth are

one-half

Half-way to the center of a planet of uniform density, your weight compared to that at the surface would be

decrease to half

If Earth's mass decreased to one-half its original mass with no change in radius, then your weight would

decrease

If Earth's radius somehow increased with no change in mass, your weight would

larger

If the Moon had twice as much mass and still orbits Earth at the same distance, ocean bulges on Earth would be

lower

If the Moon were four times as massive but twice as far from Earth, high tides on Earth would be

both of these

If the Sun were twice as massive

practically the same

Suppose the Moon had twice the diameter but the same mass and same orbital distance from Earth. In that case, the high tides on Earth would be

radial distance from Earth

The period of an Earth satellite depends on the satellite's

perpendicular to the surface of Earth

The radial velocity of an Earth satellite is its velocity
