Answer:
It is given that the image is formed at a distance of 50cm from the lens. And since the image is real, v = +50cm. This means that u = -50cm. Therefore, the needle must be placed at a distance of 50cm from the lens.
Explanation:
Pretty sure it's 10 feet of plant debris to form 1 foot of coal.

Answer:
L = 100.24 mH
Explanation:
Given that
V= 11.5 V
I= 0.62 A
V(rms) = 24 V
f= 60 Hz
I(rms) = 0.57 A
resistance R
V= I R
11.5 = 0.62 R
R= 18.54 ohm
impedance Z given
V(rms) = I(rms) Z
24 = 0.57 Z ,Z= 42.10 ohm
inductor impedance
L= 0.10024 H
L = 100.24 mH
This is the inductance .
The work done by the heat engine is 40 kCal.
The given parameters;
- input heat of the engine, Q₁ = 70 kCal
- output heat of the engine, Q₂ = 30 kCal
To find:
- the work done by the heat engine
The work done by the heat engine is the change in the heat energy of the engine;
W = Q₂ - Q₁
Substitute the given parameters and solve work done (W)
W = 70 kCal - 30 kal
W = 40 kCal
Thus, the work done by the heat engine is 40 kCal.
