Answer:
the attraction between N and S poles
Renewable energy or a energy that can be used again
Explanation:
First find the displacement in the x direction:
dₓ = 449 cos 66° + 1112 cos 169° + 1571 cos 26°
dₓ = 182.6 − 1091.6 + 1412
dₓ = 503 km
Next, find the displacement in the y direction:
dᵧ = 449 sin 66° + 1112 sin 169° + 1571 sin 26°
dᵧ = 410.2 + 212.2 + 688.7
dᵧ = 1311 km
The magnitude is:
d² = dₓ² + dᵧ²
d² = (503)² + (1311)²
d = 1404 km
The angle is:
tan θ = dᵧ / dₓ
tan θ = 1311 / 503
tan θ = 2.61
θ = 69°
1404 km and 69° north of east from New Orleans is approximately Toledo.
Answer:
Given parameters
Potential difference (V) = 220 V
Power of lamp 1 (P1) = 100 W
Power of lamp 2 (P2) = 60 W
Both the bulbs are connected in parallel. Therefore, the potential difference across each of them will be 220 V, because no division of voltage occurs in a parallel circuit.
We know that
Power = Voltage x Current
P = V x I
I = P/V
Lamp 1:
I1 = P1/V
I1 = 100/220
I1 = 5/11 A
Lamp 2:
I2 = P2/V
I2 = 60/220
I2 = 3/11 A
Net current (I) = I1 + I2
I = 5/11 + 3/11
I = 8/11
I = 0.7273 A
Hence, current drawn from the line is 0.727 A
