The answer is disorder. It would be really hard to explain without being too complicated, but the entropy is the number of possible states that a system can realize under given conditions.
Answer:
286.7 m
Explanation:
So we are assuming the PE of the falcon is converted to KE
KE = PE
1/2 (.480)(75)^2 = .480 (9.81)(h ) solve for h = 286.7 m
Answer:
The electron tends to go to the region of 4. higher electric potential.
Explanation:
When a charged particle is immersed in an electric field, it experiences a force given by
where
q is the charge of the particle
E is the electric field
The direction of the force depends on the sign of the charge. In particular:
- The force and the electric field have the same direction if the charge is positive
- The force and the electric field have opposite directions if the charge is negative
Therefore, an electron (negative charge) moves in the direction opposite to the electric field lines.
However, electric field lines go from points at higher potential to points at lower potential: so, electrons move from regions at lower potential to regions of higher potential.
Therefore, the correct answer is
The electron tends to go to the region of 4. higher electric potential.
Answer:
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
Explanation:
Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.
Because the machine does not increase the work done, if the output force is greater, the output distance must be less.
The applicable observations are ...
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
