<u>Solution and Explanation:</u>
The following calculation is made in order to find out the area and the final velocity vector.
Using the given information and the data in the question,  
m1u1 + m2u2 = (m1 + m2)  multiply with v
40000 multiply with ( -20i ) + 60000 multiply with ( 10j ) = 100000 multiply with v
    Therefore, v = -8i + 6j
That is  |v| = 10 knots towards the 36.86 degree north of the west
 
        
             
        
        
        
I'd say that because of gravity and the material made the red giant it's holding all the material together to be in one piece years and years to come.
Hope that helped! <3 ^-^
        
             
        
        
        
Answer :  <em>Her weight is lower on Venus because the acceleration due to gravity is lower.</em>
Explanation :
Venus is also called as Earth's twin. This is because both the mass and the size of Earth and Venus are almost same. The acceleration due to gravity on earth is  while on Venus is
 while on Venus is  .
.
So, when Shari measure her weight on Venus she found her weight is lower on Venus. This is because the acceleration due to gravity is lower on the surface of Venus as compared to the Earth. 
Since,    
i.e. weight depends on g.
<em>So, correct prediction is (b)</em>
 
        
                    
             
        
        
        
Answer:
<h2>4.1 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 0.205 × 20
We have the final answer as
<h3>4.1 N</h3>
