Answer:
Pushing a box with 100 newtons of force for 15 meters does more work.
Explanation:
Given,
The force for pushing a box for 5 meters, f = 200 N
The force for pushing a box for 15 meters, f = 100 N
The work done on a box is equal to the product of the magnitude of the force 'F' applied and the magnitude of displacement 'S' caused on the box.
The formula for work is
W = F · S joules
Substituting the above equation for f
W = 200 N x 5 m
= 1000 J
Substituting the for F
W = 100 N x 15 m
= 1500 J
Hence, from the above results pushing a box with 100 newtons of force for 15 meters does more work.
Answer:
The atoms start vibrating really fast, making the space between them larger. It's an increase in Kinetic Energy.
Answer:
electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged.
Scalar Quantity :-
→ These are the quantities with magnitude only . These quantities doesn't have to be mentioned with direction
eg.)=> Mass , Temprature .
Vector Quantity :-
→ These quantities are described with both Magnitude and Direction . These quantities follow special type of algebra called Vector algebra .
eg.)=> Force , Displacement

ANSWER:
Energy loss
EXPLANATION:
When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is some energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat.Sep 18, 2015
