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
