Answer:
So if we need to cover 1000 meters. And we go at a speed of 4.3 m/s. That means that every 4.3 meters we cover is 1 second. So we divide both amd get 
1000/4.3 = 232.56 is approx the answer. Also the meters cancel out because
m/(m/s) = m*s/m, cancels out giving s as a unit.
<h2><u>
Therefore the answer is 232.56 seconds</u></h2>
 
        
             
        
        
        
Answer:
It's called an ampere!
Explanation:
The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.

I think you mean the Cryosphere? 
But the answer is D- Earths Ice 
This word Cryosphere comes from the greek word "kryos" which means cold 
Many people think of the cryosphere as being the north and south poles  but snow and ice can be found in a lot of places on the Earth
 
        
             
        
        
        
The absence of external forces will make the pucks move in the form of a uniform circular motion.
<h3>What is a circular motion?</h3>
It should be noted that a circular motion simply means the movement of an object along the circumference of the circle. 
In this case, the absence of external forces will make the pucks move in the form of a uniform circular motion. 
If the friction is absent, the pucks will continue to move on the same path due to the first law of Newton and the law of conversation of energy. In this case,the results will match the predictions until there's loss in energy.
