Answer:
The work done depends upon the <u> Force</u> applied and <u>Displacement</u> produced.
Explanation:
Definition: Work is said to be on a body only if a force acting on it causes a displacement in its direction
.
In other words we can say it is the product of force and displacement
Formula:
Unit:
The unit of work is Joule.
So, work depends on the force applied and the displacement caused by the applied force.
If force is applied and there is no displacement, then work is 0
.
Example: Pushing a wall does no work.
Work is positive if force applied and displacement is in same direction.
Work is negative if force applied and displacement is in opposite direction.
Fe is an element
Aluminum is an element
HCl is a compound
Hydrogen Peroxide is a compound
I think H2 is an element
NaOH is a compound
Answer:
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
Explanation:
Answer:
C
Explanation:
As long as those numbers are subscripts then that's right
Answer:
c
Explanation:
we have only distance vs time graph so c is the right answer that cart is moving with constant speed of 0.5m/s
confirmed
first calculate distance which is from 2 to 5.5
5.5-2=3.5
apply the formula of velocity
v=s/t
v=3.5/7=0.5
