Answer:
Explanation:
Given
Mass of crate is m=574 kg
The crate is raised up to a height of 1.3 m
time taken t=2 s
Work done to raise the crate is equal to the change in its potential energy
The answer is obviously gonna be A. because it keeps the moon,sun,AND the earth in orbit otherwise we'd be thrown out into space!!!
Answer:
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
Explanation:
Given:
Let the primary voltage be,
Secondary Voltage,
Secondary Resistance,
To Find:
a)
b) I₂ = ?
c) Power = ?
d) R₁ = ?
Solution:
The ratio of primary to secondary turns of the transformer, is the ratio of primary to secondary Voltage and is given by,
Substituting the values we get
For, rms current for the secondary supply,
Substituting the values we get
Now for average power at load,
Substituting the values we get
Now for resistance connected directly across the source line Power will remain same,
Substituting the values we get
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
Answer:
energy left over from the big bang
Explanation:
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.
