This device is a transformer.
A transformer is made of two coils. An alternating current in the first coil produces a varying magnetic field and so a varying magnetic flux through the second coil. The varying magnetic flux creates an electromotive force in the second coil, for the Faraday's law of induction, that is proportional to the variation of the flux, and this electromotive force corresponds to the new voltage on the second coil.
The relationship between the voltage in the first coil (Vp) and the voltage in the second coil (Vs) is given by
where Np and Ns are the number of turns in the primary and secondary coil, respectively.
Answer:
35meV
Explanation:
To find the average translational kinetic energy you use the followinf formula:
K_B: Boltzman' constant = 1.38*10^-23 J/K
T: standard temperature = 273.15K
By replacing these values you obtain:
in eV you have:
5.65*10^-12(6.242*10^18eV)=0.035eV=35meV
Hence, the average translational energy is 35meV
Answer: 0.9264 kg
Explanation: [I'll use "cc" for cubic centimeter, instead of cm^3.
The volume is 6cm*4cm*2cm = 48 cm^3 (cc).
Density of Au is 19.3 g/cc
Mass of gold = (48 cc)*(9.3 g/cc) = 926.4 grams Au
1 kg = 1,000 g
(926.4 grams Au)*(1 kg/1,000 g) = 0.9264 kg, 0.93 kg to 2 sig figs
At gold's current price of $57,500/kg, this bar is worth $53,268. Keep it hidden from your lab partner (and instructor).
