Answer:
5
Explanation:
Let there are three capacitances, C1, C2, and C3.
Combination I:
All the three are connected in series combination.
Combination II:
All the three are connected in parallel combination.
Combination III:
C1, C2 are in parallel and then C3 in series.
Combination IV:
C1, C3 are in parallel and then C2 in series.
Combination V:
C3, C2 are in parallel and then C1 in series.
Answer:
Lower energy shell which will be nearer to the nucleus.
Explanation:
When electron move from one energy level to another, an electron must gain or lose just the right amount of energy.
When atoms releases energy, electrons move into lower energy levels. The electrons in the shells aways from the nucleus have more energy as compared to the electrons in the nearer shells.
Electrons with the lowest energy are found closest to the nucleus, where the attractive force of the positively charged nucleus is the greatest. Electrons that have higher energy are found further away
Answer:
B
Explanation:
in a liquid the particles are widespread and move around each other but in a solid they move in place and are tightly packed
The density of sample is 5 g/cm3
Given:
volume of sample = 20 cm3
mass of sample = 100 grams
To Find:
density of sample
Solution: Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume
density = mass/volume
d = 100/20
d = 5 g/cm3
So, density of sample is 5 g/cm3

Hola!
Percentage Error is a measurement of the discrepancy between an observed and a true, or accepted value.
[ refer the attachment. ]
According to Question,
% error =
× 100
= 2.631 % = 2.7 % (approximately.)
hope it helps!
