They depend on it because this helps them maintain nutirance and survive and reproduce more.
        
             
        
        
        
Answer:
<h2>
38,769.23 miles</h2>
Explanation:
given:
A car is traveling at an average speed of 70 m/s.
find:
How many km would the car travel in 6.5 hrs. ?
solution:
distance = velocity over time
let velocity = 70 m/s
            time = 6.5 hrs.
convert velocity 70 m/s into m/h for consistency of units.
<u>70 mi. </u> x   <u>3600 sec.</u>  =  252,000 mi/hour
   sec.          1 hr.
now plugin values into the formula d = v/t
d = <u>252,000 miles/hour </u>
               6.5 hours
d = 38,769.23 miles
therefore, the distance travelled in 6.5 hours with a speed of 70 m/s is 38,769.23 miles
 
        
             
        
        
        
Answer: 1
an object positioned at some height in a gravitational field
Explanation:
Gravitational potential energy of an object is the energy stored due to position of the object or position at certain height relative to zero position.
Gravitational potential energy can also be expressed as object position at some height above or below zero position in a gravitational field
I think 1 and 2 make sense. But 1 make more sense than 2
 
        
             
        
        
        
It's true IF ' m ' stands for mass and ' v ' stands for acceleration. Otherwise it's false.
 
        
             
        
        
        
Answer:

Explanation:
Given data:
PERIOD OF MOTION IS T = 25.5 days
orbital speeds = 220 km/s
we know that 
acceleration due to centripetal force is
Gravitational force
we know that

solving for





we know that
f =ma

solving for m
