Answer:
As you learned in Wave Motion, all waves have amplitude, wavelength, velocity and frequency.hope that helps
Answer:
E = (0, 0.299) N
Explanation:
Given,
- Charge

- Charge

- Distance of the first charge from the origin = (16m, 0)
- Distance of the second charge from the origin = (-9, 0)
- Point where the electric field required = (0, 12m)
Let
be the angle of the electric fields by first and second charge at the point A.

Electric field by charge
at point A,

Electric field by the charge
at point A,

Now,
Net electric field in horizontal direction at point A
Net electric field in vertical direction at point A.

Hence, the net electric field at point A,

Answer:
549.9 ohms, 65.65 watts, the power went up
Explanation: power P = V²/R
v= 190volts , P =62watts
from P =V²/R
62=190²/R
making R the subject
R×62= 190²
62R =36100
R=36100/62
R=586.25 ohms
Resistance of each lamp = 586.26/18 =32.3ohms
a) resistance of the light string now = 17×32.3 = 549.9 ohms
b) P=V²/R
where R=549.9ohms , P=?
P=190²/549.9
P=36100/549.9
P=65.65watts
Power dissipated has increased( went up )
