It’s distance for my answer but tell me if anyone tells u this answer thanks
Answer:
Explanation:
Given:
- power of battery,
- voltage across the load resistor,
- emf of the battery,
<u>Now as we know that the electric power is given as:</u>
here: resistance of the load
a)
Now the load resistance:
b)
Using Ohm's law, current in the load:
Now,
where: internal resistance
Answer:
The effect of lowering the condenser pressure on different parameters is explained below.
Explanation:
The simple ideal Rankine cycle is shown in figure.
Effect of lowering the condenser pressure on
(a). Pump work input :- By lowering the condenser pressure the pump work increased.
(b) Turbine work output :- By lowering the condenser pressure the turbine work increased.
(c). Heat supplied :- Heat supplied increases.
(d). Heat rejected :- The heat rejected may increased or decreased.
(e). Efficiency :- Cycle efficiency is increased.
(f). Moisture content at turbine exit :- Moisture content increases.
Answer:
210 m
Explanation:
The speed of train 2 relative to train 1 is 15 m/s + 20 m/s = 35 m/s.
It takes 6 seconds for the train to pass, so the length of the train is:
(35 m/s) (6 s) = 210 m
Answer:
3100
Explanation:
Because no extra force is implied for it to exalarate
