Gravity method in geophysics

What happens to the velocity of a ball as it is dropped off a cliff? 

• It decreases at a uniform rate 
• It increases at a uniform rate 
• It is constant 
• It increases at a non-uniform rate

The data collected supports which of the following questions that Squidward could have tested?

• Which song does the audience prefer?
• Which instrument does the audience like best?
• Which reed length creates the best sound?
• How do applause affect performance?

Squidward found new reeds to tryout for his clarinet.  He used an APPLAUSOMETER to measure applause after playing  Under the Sea with each reed.  The results were put in the table.
What was the dependent variable?

• The Song
• The Reed
• The Applause

A ball is thrown upward with an initial speed of 30m/s. At what location will the ball be moving downward with a speed of 20m/s

• A

• B

• E

• F

A ball is thrown upward with an initial speed of 30m/s. At what location will the ball be moving upward with a speed of 20m/s

• A

• B

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

Squidward found new reeds to tryout for his clarinet.  He used an APPLAUSOMETER to measure applause after playing  Under the Sea with each reed.  The results were put in the table.
What was controlled?

• The Song

What is the velocity of an object that has been falling freely in a vacuum for 2 seconds?

• 10 m/s down

• 10 m/s up

• 20 m/s down

• 40 m/s down

The acceleration of objects falling on Earth due to gravity is

• 9.8 m/s

• 9.8 m/s²

• 9.8 g/mL

• 9.8 g/m/m
