Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
Answer:
20 electrons
Explanation:
The atomic number equals the amount of protons in an atom's nucleus, but this number is also equal to the amount of electrons. So if the atomic number is 20, that means there are 20 protons and 20 electrons. ( they need to balance out since they have opposite charges)
I hope that helps :)
Answer: b
Explanation: t affects weather patterns, it affects ocean currents, and it even affects air travel. As important as the Coriolis Effect is, many have not heard about it, and even fewer understand it. In simple terms, the Coriolis Effect makes things (like planes or currents of air) traveling long distances around the Earth appear to move at a curve as opposed to a straight line.
It’s a pretty weird phenomenon, but the cause is simple: Different parts of the Earth move at different speeds.
Answer:
2193.8 PSI is the pressure in the tank
Explanation:
We apply the Ideal Gases Law to solve this:
P . V = n . R . T
T° is the temperature in K, so we must do the conversion:
35°C + 273 = 308K
P . 1650L = 9750 mol . 0.082 L.atm/mol.K . 308K
P = (9750 mol . 0.082 L.atm/mol.K . 308K) / 1650L → 149.24 atm
Let's make the conversion:
1 atm = 14.7 PSI → 149.24 atm . 14.7 PSI / 1 atm = 2193.8 PSI
The shortest distance taken by the object to reach the destination at a minimum time is called acceleration. Thus value acceleration depends upon the displacement and time.
