Answer:
<em>The voltage at the middle source is</em>
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:
The sum of these voltages is:
Operating:
We know the total voltage is , thus:
Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is
Answer:
14 apples, 10 bananas
Step-by-step explanation:
.07 * 12 = .84 (12 apples at 7 pence/per = 84 pence)
5 - .84 = 4.16 (4.16 pound remaining)
4.16/.4 = 10.4 (you can buy 10 bananas with 4.16 pounds, with .16 pence remaining)
.16 / .7 = 2.3 (you can buy two more apples with 16 pence)
Hope this helps.

Answer:
Compressions
Step-by-step explanation:
The third type is compressions
X is 50 degrees as its a right angle (90 degrees) so its 90-40=50
