My answer -
The scientist that performed the cathode ray experiment leading to the discovery of electrons is<span> the
scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized
after the discovery that electrons are present in the atom. In this
model, the atom is composed mainly of electrons. It was describe as plum
pudding because the electrons are dispersed within the atom.
P.S
Happy to help you have an AWESOME!!! day ^-^

Answer:
Explanation:
From the question we are told that:
1st Energy
2nd Energy
3rd Energy
Generally the equation for Energy E for electron in one dimensional box at ground state is mathematically given by
Therefore Length a is mathematically given as
City B is at a higher temperature because as you go higher in altitude the boiling point of water becomes lower.
Answer:
Aluminum is ideal for aircraft manufacture because it's lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum's high resistance to corrosion ensures the safety of the aircraft and its passengers.
Explanation:
This
can be solved using Dalton's Law of Partial pressures. This law states that the
total pressure exerted by a gas mixture is equal to the sum of the partial
pressure of each gas in the mixture as if it exist alone in a container. In
order to solve, we need the partial pressures of the gases given. Calculations
are as follows:<span>
<span>P = 3.00 atm + 1.80 atm + 0.29 atm + 0.18 atm + 0.10 atm</span></span>
<span><span>P = 5.37 atm</span></span>
