For efficiency the top one is 50% and the bottom one is 72%
The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. The object is said to have reached a terminal velocity.
The option that takes place as water cycles from the bottom of the pot toward the top is that A. thermal energy is transferred.
As the pot gets warmer and warmer, the heat flows everywhere inside the pot, ultimately reaching the top, and heating the water at the top as well. There is no chemical energy here, and molecules don't gain thermal energy, it is just transferred to the top of the pot.
The force exerted by a pressure of any gas over a surface its given by the formula P=F/S (where P is pressure, F force and S surface).
We can multiply both sides of the formula by S to obtain the force.
P*S=(F*S)/S
P*S=F
Solve for P=1.80*10^5 Pa and S=4.10*10^-4 m^2 ([Pa] =[N/m^s])
(1.80*10^5 N/m^s) * (4.10*10^-4 m^2) =F
73.8 N =F
Answer:
Hi,
The correct answer option is; D. Most of the current will flow through one part of the circuit.
Explanation:
A short circuit is a low resistance path in an electric connection between two conductors supplying current in a circuit.
It happens when excess amounts of current flow in the power source through a 'short path'.
Short circuits occur at very high temperatures which is of course caused by the heat produced during dissipation.
An example of application of short circuit is arc welding, where heating is achieved through short circuit.
