Answer:
C part of the wave was reflected back into the original medium
Explanation:
It is Jupiter.
Jupiter is the biggest planet in the solar system. No wonder ancient astronomers named it after Jupiter, King of the Roman gods. More than 1,000 planets the size of Earth could fit inside Jupiter. A tunnel through Jupiter would be eleven times longer than a tunnel through Earth. A trip around Jupiter's equator would take aix times longer than a trip around the Earth's equatior.
The great red spot is the most thrilling sight on the surface of Jupiter. The "spot" is twice as wide as the planrt Earth! Most astronomers think that the great red spot is as huge storm that has been raging for at least 300 years. (Thats as long as people have been obseving the planet.)
Answer:
R = 9.85 ohm , r = 0.85 ohm
Explanation:
Let the two resistances by r and R.
when they are connected in series:
V = 12 V
i = 1.12 A
The equivalent resistance when they are connected in series is
Rs = r + R
So, By using Ohm's law
V = i Rs
Rs = V / i = 12 / 1.12 = 10.7 ohm
R + r = 10.7 ohm .... (1)
When they are connected in parallel:
V = 12 V
i = 9.39 A
The equivalent resistance when they are connected in parallel
So, By using Ohm's law
V = i Rp
Rp = V / i = 12 / 9.39 = 1.28 ohm
.... (2)
by substituting the value of R + r from equation (1) in equation (2), we get
r R = 8.36 ..... (3)
..... (4)
By solvng equation (1) and (4), we get
R = 9.85 ohm , r = 0.85 ohm
