Revolt · Accepted Answer

increases

Question 3

A group of scientists is trying to launch an object into orbit, and the object is traveling at 6500 m/s. Which best explains why the object will not successfully orbit Earth?

Revolt · Accepted Answer

The object is not traveling fast enough to match Earth’s curvature.

Question 4

Which would cause the greatest increase in the acceleration of a satellite?

Revolt · Accepted Answer

a decrease in the radius and an increase in the tangential speed

Question 5

What causes a satellite to move tangentially to a circular path?

Revolt · Accepted Answer

inertia

Question 6

Hannah has information about an object in circular orbit around Earth. mEarth = 6.0 × 1024 kgG = 6.67 × 10–11 rearth=6.0 x 106 m

Revolt · Accepted Answer

the distance of the orbiting object to Earth

Question 7

How high above Earth is a satellite orbiting if its tangential velocity is 5000 m/s? Earth’s mass is kg and its radius is m.

Revolt · Accepted Answer

9,608,000 m

Question 8

Sid created a chart to summarize characteristics of satellite motion. Which best describes Sid’s error?

Revolt · Accepted Answer

Centripetal force is perpendicular to the velocity of the satellite.

Question 9

Revolt · Accepted Answer

Y and Z

Question 10
