We can use the formula P=IV to calculate the current, where “P” is power (measured in watts), “I” is current (measured in Amps), and “V” is voltage. Simply plug and solve:
P = IV
(3.5 Watts) = I(120 volts)
I = 0.0292 Amps
The current flowing through the bulb is approximately 0.0292 Amps.
Hope this helps!
Answer:
Explanation:
Combination of oxidation and reduction reactions.
Where there is oxidation, there is reduction too.
Explanation:
TO calculate emperical formula , we need percentage composition of the elements and molecular mass of a specific compound which is already given in the question
then create a table with 1.name of element, 2.percentage given and its atomic mass , 3.no. of moles
( %given/at.mass of element) ... then take the least value in the no. of moles you have found now and divide with each no. of moles value .. to get a simple digit number.
You have got the empirical formula
1) It was Avogadro (option E).
The full name is Amadeo Avogadro. He was a famous Italian scientific. He formulated the Law that states that same volume of gases at same temperature and pressure corresponds same number of particles.
2) Cathode rays are electrons and have the largest charge mass / ratio of fundamental particles found in the atom (option E)
For example, electrons have the same charge magnitude than protons, but the mass of the electrons is a small fraction of the mass of the protons. (1/1840)
