Answer:
Carnot heat pump
Explanation:
Carnot heat pump is an ideal heat pump in which all processes are reversible and that consume minimum amount of work to and produces maximum amount of heating effect compare to all real engine.And that is why COP of Carnot heat pump is more as compare to real heat pump.
All real heat pump are not perfectly reversible heat pump So this is also called irreversible heat pump .Due to irreversibility the COP of irreversible heat pump is always less than the COP of Carnot heat pump.
Answer:
Yes
Explanation:
The core of an electromagnet serves to stabilize the magnetic field created by the wire. The thicker the core, the more metal there is to amplify the current. Therefore, a thicker core does make an electromagnet stronger. Hope this helps!
Answer:
$7,778.35
Explanation:
At year 3, the final payment of the remaining balance is equal to the present worth P of the last three payments.
First, calculate the uniform payments A:
A = 12000(A/P, 4%, 5)
= 12000(0.2246) = 2695.2 (from the calculator)
Then take the last three payments as its own cash flow.
To calculate the new P:
P = 2695.2 + 2695.2(P/A, 4%, 2) = 2695.2 + 2695.2(1.886) = 7778.35
Therefore, the final payment is $7,778.35
Answer:
Prevent electrical shock
Grounding is a non current carrying conductor mainly used to guard against hazards due to leakage in electric circuits
Explanation:
The grounding refers to the connection of an electrical equipment exposed metallic parts to the ground to serve as a source of current flow in the event of an insulation failure will cause the fuses to trip thereby isolating or removing electric power from the device
Grounding also prevents the accumulation of static electricity which can be a source of fire in inflammable areas.
Answer:
The correct answer is;
In the reverse order you connected them
Explanation:
The process of jump starting a car is as follows;
1) Connect the positive or red clip to the dead battery
2) Connect the other end of the positive or red clip to the other end of the live battery in the donor car
3) Connect the negative or black clip to the negative terminal on the live battery
4) Connect the other end of the negative or black clip to the bare metal (without paint coating) on the donor car
5) Start and idle the donor car
6) Test to see if there is electric power in the dead car. If yes, then start the dead car
By disconnecting in the reverse other, that is by first removing the black or negative terminal from the dead vehicle chassis, prevents short circuiting the system with the rest of the metals parts in vehicle body when a metal makes contact while the positive terminal is removed and the negative terminal is still on the chassis.
