Answer:
The voltage of the generator is 7.27 kV.
Explanation:
Given that,
Output of generator = 440 V
Current = 20 A
Resistance = 0.60 Ω
Power loss =0.010%
We need to calculate the total power of the generator
Using formula of power
Where, V = voltage
I = current
Put the value into the formula
Th power lost on the transmission lines
The current passing through the transmission line
We need to calculate the voltage of the generator
Using formula of voltage
Put the value into the formula
Hence, The voltage of the generator is 7.27 kV.
<u>Answer:</u>
The modern atomic theory has given by "John Dalton and framed postulates".
<u>Explanation:</u>
The fundamental role of atoms in chemistry is established by the modern theory of atoms mentioned in 1808 for the first time by an English scientist named John Dalton. This consists of three sections such as all matter is composed of atoms, atoms of the same element are the same while atoms of different elements are different, atoms combine to form compounds in full-number ratios.
The unique characteristic of the "number of protons" is that all atoms of the same compound share. While the atoms of the same element i.e having a similar number of protons can have different numbers of neutrons and such elements are called isotopes.
Answer:
Electron groups could be considered as Lone pair electrons and bonded pairs of electrons.
Answer: Option D & B
Explanation:
The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.
I got this from another brainly user
Depends on the weight of the bird.
1) Half a mile is about 800m.
2) 14000 lbs = about 6 tones, same like couple 4WD
3) Fuel consumption is about 20L per 100km or 0.2l each 1km or 0.16L within 800m
4) density of fuel is about 70% of density of water so .... weight of 1.6L of fuel burned would be about 1.6*0.7=1.1 kg
So if birds mass would be below 1 kg - the bridge will not collapse. But if it would be a pelican with the mass of 9kg - it would be a drama :)

Explanation:
The cowbird is a natural enemy to the sparrow. It is sort of a disease to the a disease to the sparrow. That being so, when the disease goes away, the sparrow bird population should go up. Fewer deaths due to the cowbird, means more sparrows around.
