Forces between objects will decrease as the objects are moved farther away from each other.
In this case the force is decreased by 4 times because the objects are moved 4 times away from each other.
hope this helps :)
The answer is A. Increase
The formula is <span>Voltage = Resistance X Current
Lets say the voltage is 10 and the resistence is 5
10 = 5 x current
Current = 2
Now, lets decrease the resistence from 5 to 2
10 = 2 x Current
Current = 5
The current increases

Should the question say “what is the weight of the truck”? :)
I can then answer it. There is no information to find the weight of the boat ;)
Answer:
1)
from the positive x-axis.
2) 
Explanation:
Given:
speed of rowing in still water, 
1)
speed of water stream, 
we know that the direction of resultant of the two vectors is given by:

where:
the angle of resultant vector from the positive x-axis.
angle between the given vectors
When the rower wants to reach at the opposite end then:

so,




from the positive x-axis.
2)
Now the resultant velocity of rowing in the stream:



Therefore time taken to cross a 4 miles wide river:
