Answer:
45 W
Explanation:
First of all, we need to find the work done by the person to lift the bag. The work done is given by
where
F = 75.0 N is the force applied
d = 1.50 m is the displacement of the bag
Substituting numbers into the formula,
Now we can find the power used, which is given by
where
t = 2.50 s is the time taken
Again, using W=112.5 J, we find
Answer:
vaporization ,( Evaporation)
Answer:
the book is exerting a force of 15N on the table as we know that every action has an equal but opposite reaction so there must be a force acting on it in the opposite direction the other force normal force or we can say it perpendicular force that is defined as a contact force perpendicular to the contact surface that prevent two objects from passing over one another

Answer:
No.
Explanation:
The force that two particle experience is inversely proportional to the sqare of the distance, this is:
for a distance D
If we move them so that D is doubled:
= 
Then the force they experience is one fourth of the original.
