Covalent bonding occurs when pairs of electrons are shared by atoms.
B. Barometer is used to measure atmospheric pressure.
Answer:
Z = 530.89 ohms
Explanation:
Given that,
Resistor, R = 40 ohms
Inductor, L = 3 mH
Capacitor, C = 5 μF
We need to find the impedance of the circuit at frequency of 60 Hz. For a series LCR circuit, its impedance is given by the formula as follows :
So, the impedance of the circuit is 530.89 ohms.
The identity of the element is determined by the number of protons
in the nucleus of each atom.
If two atoms have the same number of protons in their nucleii
(nucleuses) but different numbers of neutrons, then they're both
atoms of the same element, but their atomic masses are different,
and they're called isotopes of the element.
In the picture, atoms 'A' and 'B' each have 3 protons in the nucleus,
so they're both atoms of Lithium. But the number of neutrons is
different, so 'A' and 'B' are different isotopes of Lithium.
Also in the picture, atoms 'C' and 'D' each have 4 protons in the
nucleus, so they're both atoms of Beryllium. But the number of
neutrons is different, so 'C' and 'D' are different isotopes of Beryllium.
Plants are very sensitive creature therefore responds to any thing that comes its way ,therefore the way they respond to heat light and energy in the same proportion because they work together in helping plants manufacture their own food through the process of photosynthesis
