Step-by-step explanation:
Equation for circle centered at origin:
x² + y² = r².
Therefore r² = (-4)² + (-2)² = 20, r = √20.
Hence d = 2r = 2√20 = 8.94 (2d.p.)
Answer:
It a simultaneous equation so the solution is 2
Step-by-step explanation:
The answer is 16 because 16•5=80 and then 80-9=71 yk?
Answer:
The value of currents are
,
and
.
Step-by-step explanation:
The Ohm's law states that

it is given that the V₁=3V and V₂=4V.
In a parallel circuit:
- Voltage is same in each component
- Sum of the currents equals to the total current that flows.
.... (1)
Equation for first loop is,

..... (2)
Equation for second loop is,

..... (3)
On solving (1), (2) and (3) we get



Therefore the value of currents are
,
and
.
