Answer:
through layers of hot air just above a surface,causing it to follow a curved path.
the answer would be the last one because kinetic energy is something in motion.
hope it helps.
The answer you're looking for is True
Distance between successive compression is wavelength !
so answer is D !!
The equivalent resistance of the three resistors when connected in parallel is:
![\frac{1}{R_{eq}} = \frac{1}{R_1}+ \frac{1}{R_2}+ \frac{1}{R_3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7BR_%7Beq%7D%7D%20%3D%20%5Cfrac%7B1%7D%7BR_1%7D%2B%20%5Cfrac%7B1%7D%7BR_2%7D%2B%20%5Cfrac%7B1%7D%7BR_3%7D%20%20%20%20)
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
![\frac{1}{R_{eq}} = \frac{1}{R}+ \frac{1}{R}+ \frac{1}{R}= \frac{3}{R}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7BR_%7Beq%7D%7D%20%3D%20%5Cfrac%7B1%7D%7BR%7D%2B%20%5Cfrac%7B1%7D%7BR%7D%2B%20%5Cfrac%7B1%7D%7BR%7D%3D%20%5Cfrac%7B3%7D%7BR%7D%20%20%20%20%20)
And since we know the value of the equivalent resistance,
![R_{eq}=85 \Omega](https://tex.z-dn.net/?f=R_%7Beq%7D%3D85%20%5COmega)
, we can find the value of R:
![R=3 R_{eq} = 3 \cdot 85 \Omega=255 \Omega](https://tex.z-dn.net/?f=R%3D3%20R_%7Beq%7D%20%3D%203%20%5Ccdot%2085%20%5COmega%3D255%20%5COmega)
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
