Answer:
Consult not your fears but your hopes and your dreams. Think not about your frustrations, but about your unfulfilled potential. Concern yourself not with what you tried and failed in, but with what it is still possible for you to do.
There are problems with the first sentence, and it's not really needed when
working with this question. So let's just take the 20 (Hz ?) frequency from
the first sentence, and ignore the rest of it for right now.
Wavelength = (speed) / (frequency) =
(331 m/s) / (20 Hz) = <em>16.55 meters</em>.
Answer:
About 7.5 years
Explanation:
The orbital period is proportional to the semimajor axis raised to the power of 3/2.
The orbital period is <em>also</em> inversely proportional to the square root of the sum of the masses of the sun and the asteroid; however, the sun's mass is a constant and the asteroid's mass is negligible in comparison with the sun's mass.
2.4 ounces is the average weight of a hot wheels car.
Answer:
Explanation:
Mass of gold deposited = 0.5 g
Molar mass of gold = 197 g/mol
Time, t = 6 hours
= 6 × 3600
= 12600 s
Number of moles = mass/molar mass
= 0.5/197
= 0.00254 mole
Assuming
Au --> Au+ + e-
Faraday constant = 9.65 x 104 C mol-1
Q = 96500 × 0.00254
= 244.924 C
Q = I × t
I = 244.924/12600
= 0.011 A
= 11.34 mA.
