Answer:
The dependant variable is obvrioulsy going to be the temperature of the watch, and the independan variable is going to be the amount of water ebing poured into the cups.
Explanation:
The temperature is the dependant variable by how it is the thing being observed, or recorded. Your independant variables could be a few things from wha information I have but it could be either, the amount of water being poured into the cups, the temperature of the water being poured, or the amount of time between each new temperature of wather bing poured into the cups.
yes but all of these are correct answers
Answer:
44 ohm, 145 ohm
Explanation:
R = 44 ohm, L = 2.2 mH = 2.2 x 10^-3 H
At f = 60 Hz
XL = 2 π f L = 2 x 3.14 x 60 x 2.2 x 10^-3 = 0.82896 ohm
Impedance,
Z = 44 ohm
At f = 10 kHz = 10000 Hz
XL = 2 π f L = 2 x 3.14 x 10000 x 2.2 x 10^-3 = 138.16 ohm
Impedance,
Z =1 45 ohm
Explanation:
Given that, two successive resonant frequencies for an open ended organ pipe (open at both ends) are 801 Hz and 890 Hz.
(a) The frequency in case of organ pipe open at both ends is given by :
L is the length of the pipe
if f = 801 Hz
.........(2)
If f = 890 Hz for (n+1)
So, .........(2)
Dividing equation (1) and (2) we get:
On solving,
n = 9
(b) The speed of sound in air, v = 343 m/s
L = 1.92 meters
Hence, this is the required solution.
