Answer: True.
Explanation:
The US constitution has involved details related to the Supreme Court; in fact, the US constitution created this institution. However, the structure does not specify how many judges will sit in the supreme court. Those details were left to the US Congress. In 1807, Congress increased the number of judges to seven; In 1837 the number increased to nine, and in 1863 it rose to 10.
 
        
             
        
        
        
Newton's first law of motion is an object in motion stays in motion until acted upon by another force. Driving at 30 mph in a car is going to stay constant until you crash the car into a wall, stopping the car.

I can't guess what -9.8 m/s means until you tell me where it came from, 
or what 'm/s' means.
If perhaps it has something to do with the acceleration of gravity on Earth, 
then the correct figure is ' -9.8 m/s² '.  That means that any object that 
has no other force acting on it except gravity has its speed changing by 
9.8 meters per second every second.  Since it's gravity doing the job, 
then the object's speed is either increasing down, or decreasing up.  
If an object has negative velocity, then it's moving in the direction opposite 
to the direction that you decided to call positive when you started doing the 
problem.
For example, if you decide that up is positive and down is negative, and 
then somebody drops a stone from the top of a tall building, then the 
gravitational force on the stone is negative (pointing down), its velocity 
is negative (it's falling towards down), and its acceleration is negative (its 
speed towards down is getting faster and faster).  Everything is negative,
only because you decided that up is positive and down is negative.  It's
nothing to be worried about.
