Answer:
(a) 12210 Ω
(b) 9.92 Ω
Explanation:
From Electricity,
(a)
When resistors are connected in series, the total resistance is the sum of the individual resistance.
From the question,
Rt = R1 + R2 + R3................................. R37 ....................... Equation 1
Where Rt = Total resistance of combined resistance, R1 = resistance of the first resistor, R2 = Resistance of the second resistor .......... and so on up to the 37th resistor.
Note: Since The resistor are identical.
Rt = n(R) ..................... Equation 2
Where n = number of resistor, R = resistance of each resistor.
Given: n = 37, R = 330 Ω
Substitute into equation 2
Rt = 37(330)
Rt = 12210 Ω
(b)
For parallel connection,
Rt = R/n...................... Equation 2
Given: R = 330 Ω, n = 37
Substitute into equation 2
Rt = 330/37
Rt = 8.92 Ω
Hence the resistance when connected in parallel = 9.92 Ω
It's not non testable facts..I just took the test and got it wrong.
V=vnaut+at 0(want it to stop)=25+-8t(negative accel cuz its deceling)
-25/-8=t t=3.125 seconds or with sig figs 3.1 seconds
x=xnaut+vnaut*time+1/2*a*time^2
x(where it ends up)=0(we start distance from when it started to brake)+25*3.1+1/2*-8*3.1^2=39.06 meters or 39.1 meters
x=0+25*3.1-.5*8*3.1^2 is the same equation as above with nothing written in. Are you in physics ap or reg? either way friend me lol(just joined website tonight)
Answer is key whole saw.
Key whole saw is more often used to cut holes to install outlet boxes into a old installations.
Hope it helped you.

Answer:
b) the potential difference across each is the same.
Explanation:
When resistors are connected in parallel with each other
then the terminals of all the resistors will connected across the terminals of the battery
So we know the potential difference of the battery is same across all the resistors
So we can say that the equivalent resistance of all the resistance is
so its not the mean of all resistors
also we know that the resistance are all different so power across each resistance is different given as
also current in each resistance is also different and given by
so correct answer will be
b) the potential difference across each is the same.
