The coefficient of expansion is 13 * 10^-6 m per meter length.per oK
The temperature difference = 42 - - 8 = 50 oC
delta T = (42 + 273) - (-8 + 273) = 50 oK
delta L = L * 13* 10^6 m/oK
oK = 50 oK delta L = 19.5 cm = 19.5 cm [1m / 100 cm] = 0.195m
So we need to find the length and it is computed by:
0.195= L * 13 * 10^-6 * 50 L = 0.195 / (13*10^-6*50) L = 300 m
The new pressure of the air in the syringe is 1.5 atm.
<h3>What is the new pressure of the syringe?</h3>
The new pressure of the air in the syringe is calculated as follows assuming the temperature remains constant;
P2 = P1V1/V2
P2 = 1 * 60/40
P2 = 1.5 atmospheres
In conclusion, pressure varies inversely as volume.

Answer:
the current of 12 ohm is 2A
I think that is clearly in the name. It will use 850W at 100% load if the cos¿ = 1
Explanation:
Because the simple cell is not used to produce current for a long time because of the defects like polarization and local action.
