Answer:
14.57 ohms
Explanation:
Here in the figure ,Rb & R₄are in series & also Rc & R₅ are in series. As they are in series , ( Rb + R₄ ) & (Rc & R₅) are in parallel . So the equivalent resistance in that branch = ( 2 + 18 ) ║ ( 3 + 12 )
= 20 ║ 15
= (20×15) / (20 + 15)
= 8.57 ohms
Also Ra ( 6 ohm ) is in series with that branch ,. So the equivalent resistance of the whole circuit = 8.57 + 6 = 14.57 ohms.
The solar system :)))))))))
It can impact the waters by polluting it and impact fish life's and if we have a drought we can't use this power source
Answer:
1.2kV
Explanation:
We are given that
Linear charge density,
We have to find the potential difference between poinst 5.0 m and 6.0 m from the wire.
We know that potential difference of wire
Where
Substitute the values
1kV=1000 V
Your approach is correct, but as you thought, the unit of measurement of mass is not in accordance with the unit of measurement of gravity: one is kg, the other one in N/g.
If you bring everything to kg, mass is correct and gravity will be g = 9.8 N/kg.
Therefore:
E = (m·g)/q = (8.2E-3×9.8)/(-3.3E-9) = -2.435E7
You get the same result if you use grams: m = 8.2g and g = 9.8E-3 N/g:
E = (m·g)/q = (8.2×9.8<span>E-3</span>)/(-3.3E-9) = -2.435E7
