Answer:
The work done on the system can be accounted for by;
Both and
Explanation:
The speed of the crate = Constant
Therefore, the acceleration of the crate = 0 m/s²
The net force applied to the crate, = 0
Therefore, the force of with which the crate is pulled = The force resisting the upward motion of the crate
However, we have;
The force resisting the upward motion of the crate = The weight of the crate + The frictional resistance of the ramp due to the surface contact between the ramp and the crate
The work done on the system = The energy to balance the resisting force = The weight of the crate × The height the crate is raised + The heat generated as internal energy to the system
The weight of the crate × The height the crate is raised = Gravitational Potential Energy =
The heat generated as internal energy to the system =
Therefore;
The work done on the system = + .
Answer:
C. valence electrons
Explanation:
Each dot is a valence electron.
Also, in my school, we called them Lewis Dot Structures.
Answer:
gravity
Explanation:
it pulls everything down and the futher it goes the faster it accelerates gaining lots of speed and gravity is the only force that pulls thangs down
A substance that can conduct a current in solution is salt.
