Answer:
38503.5N
Explanation:
Data obtained from the question include:
P (pressure) = 5.00 atm
Now, we need to convert 5atm to a number in N/m2 in order to obtain the desired result of force in Newton (N). This is illustrated below:
1 atm = 101325N/m2
5 atm = 5 x 101325 = 506625N/m^2
A (area of piston) = 0.0760 m^2
Pressure is force per unit area. Mathematically it is written as
P = F/A
F = P x A
F = 506625 x 0.0760
F = 38503.5N
Therefore, the force exerted on the piston is 38503.5N
ancient Greece of 400 B.C.there was a brilliant philosopher named Democritus, and he proposed the Greek word atomos, which means uncuttable. And so as he explained, all matter was eventually reducible to discrete, small particles or atomos.
Answer: I think it’s A sorry if I’m wrong
Explanation:
Answer:
By using renewable energy sources.
Explanation:
You need to satisfy a quota of energy for (whatever country you live in). People do this by using the cheapest way of producing the most energy, the most efficient. Sounds great right? Wrong! It stuffs our atmosphere with harmful gasses like carbon dioxide. You can reduce the use of these fossil fuels by using renewable energy sources such as windmills, watermills, and most notable, solar panels!
Answer is 56 protons and 56 electrons.
<em>Explanation;</em>
Atomic number is equal to number of protons. Hence, when the atomic number is 56, it means that atom has 56 protons.
When the element is in neutral state, number of protons = number of electrons. Hence, we can say that barium atom has 56 electrons.
But same element can have different number of neutrons. Those are called isotopes. Hence, we cannot say that there are 56 neutrons in barium atom without having its mass number. (Mass number = number of protons + number of neutrons)
