Answer: 4
Explanation: I watched them win their 3rd and 4th
Answer:
The angular displacement is not a length (not measured in meters or feet), so an angular displacement is different than a linear displacement. ... As the object rotates through the angular displacement phi, the point on the edge of the disk moves distance sa along a circular path.
Answer:
Here we need to make parallel connection of two 80 ohm resistors to achieve 40 ohm net resistance.
Explanation:
As we know that the resistances in series add up directly and here we are given with only the resistors of 80 Ω.
So when we connect two resistors of 80 ohm in parallel we get the resultant of 40 ohm.
Mathematically:
![\frac{1}{R_p} =\frac{1}{R} +\frac{1}{R}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_p%7D%20%3D%5Cfrac%7B1%7D%7BR%7D%20%2B%5Cfrac%7B1%7D%7BR%7D)
![\frac{1}{40} =\frac{1}{R} +\frac{1}{R}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B40%7D%20%3D%5Cfrac%7B1%7D%7BR%7D%20%2B%5Cfrac%7B1%7D%7BR%7D)
![\frac{1}{40} =\frac{2}{R}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B40%7D%20%3D%5Cfrac%7B2%7D%7BR%7D)
gives us the only combination of two resistors in parallel.
