RT = R1 R2/ R1 + R2
R1 = R2 = 2k ohm
RT = R/2 = 2k/2 = 1k ohm
Answer:
Take the numbers and fill them in graph.
Plot time as X and speed as Y and afterward join then like a line graph.
Total resistance = voltage / current = 220 / 5 = 44 ohms .
Even one 176-ohm resistor is too much. The current through it is 1.25 A,
and more than one of them in series reduces the current even further.
Connecting them in <em><u>parallel</u></em>, however . . .
Four resistors of 176-ohms each, in <u>parallel</u>, have a net effective resistance
of 176/4 = 44 ohms ... exactly what you need to do the job.
Answer:
in the direction of the first body
Explanation:
Given:
- mass of the first ball,
- velocity of the first ball,
- mass of the second ball,
- velocity of the second ball,
<u>Now for the head-on inelastic collision:</u>
(since the bodies combine after an inelastic collision.)
in the direction of the first body. (Since the net result is positive as assumed in the equation for the first body)
The answer is D. How do your environment and your genes interact to make you who you are
