Answer:
The answer is "Option a".
Explanation:
The concave lenses are there for narrow-sighted people, convex for the far people. In eyewear, curved lenses are used to rectify visibility. Since in nearsighted individuals the width between the eye lens as well as the retina is larger than should be, these readers can't clearly distinguish distant things.
The correct answer is A. Electromagnetic waves can transfer energy without a medium. Heat can be transferred through a vacuum only via radiation. Infrared waves are electromagnetic waves that does not require a medium to travel. Heat is transferred in a vacuum in the form of infrared waves.
Answer:
Sorry to tell you this but there’s no answer for that
Explanation:
Answer:
Explanation:
There are a couple of ways you could do this.
The easiest is to use E*R1/(R1 + R2)
- E = 10 volts
- R1 = 590 ohms
- R2 = 840 ohms
So the result would be
E_590 = 10 * 590/(590 + 840)
E_590 = 10 * 590/ (1430)
E_590 = 4.13 volts rounded.
You could do this a slightly longer way.
R = 1430 (total ohms in series.
E = 10 volts
I = ???
I = E/R
I = 10 / 1430
I = 0.00699
Now use this current to figure out the voltage drop.
E = I * R
I = 0.00699 amps
R = 590 ohms
E = 0.00699 * 590
E = 4.13 volts
Pick the way of doing it you like best.
