This one is much more difficult but I'd gamble my answer on D. Sorry if this one is less helpful but I only know so much.
Answer:
In energy terms, electrical potential energy in the battery is converted into kinetic energy of moving electrons.
Explanation:
Answer:
Explanation:
We are given that
At distance 0.186 cm
The electric field,E=490 N/C
We have to find the electric filed at distance 1.35 cm from the sheet.
We know that
Electric field due to large sheet ,E=
Where =Surface charge density
Electric filed of sheet does not depend on distance.It is constant.
Electric filed at distance 0.186 cm=490 N/C
Therefore, the electric filed at distance 1.35 cm is also 490 N/C.
Hence, at distance 1.35 cm , the electric filed
Answer:
32.11 g/mol
Explanation:
Given;
32S => 91.65%, 31.97g/mol
33S => 2.4%, 32.97g/mol
34S => 5.95%, 33.97g/mol
The molar mass of sulfur in the sample is the weighted average of the molar masses of its isotopes based on the percentage abundances.
i.e
molar mass = ( x 31.97) + ( x 32.97) + ( x 33.97)
molar mass = (0.9165 x 31.97) + (0.024 x 32.97) + (0.0595 x 33.97)
molar mass = (29.30) + (0.79) + (2.02)
molar mass = 32.11g/mol
Therefore the molar mass of sulfur in the sample is 32.11 g/mol
