Answer:
Explanation:
velocity of ship with respect to water = 6.5 m/s due north 

velocity of water with respect to earth = 1.5 m/s at 40° north of east 

velocity of ship with respect to water = velocity of ship with respect to earth - velocity of water with respect to earth 



The magnitude of the velocity of ship relative to earth is  = 5.66 m/s
 = 5.66 m/s 
 
        
             
        
        
        
Gravitational force depends on inverse square law. That is, gravitational force is inversely proportional to square of distance between asteroids.
As distance between them decreases, gravitational force increases. Hence A is correct.
        
                    
             
        
        
        
The third law of thermodynamics,the principle of temperature.
This law states that the entropy at 0 is always equel to 0.
This means that it is impossible to cool down a perfect 0 or absolute 0(-273.15 C)
        
                    
             
        
        
        
In order to find the force (F), you would have to use the formula for it:
F=ma
where m is mass and a is acceleration.
In the problem, the mass is 2.85kg and the acceleration is 4.9m/s^2.
Therefore,
F=2.85kg(4.9m/s^2)
F=13.965kg(m/s^2)
Since N=kg(m/s^2) 
F=13.965N
And because the problem requires that we use only 2 significant figures,
F=13N
Therefore, the student must exert 13N of force.
