Answer:
Explanation:
Let's do it in Python, we can start by prompting user for the inputs
month = int(input("Enter a month (in numeric): "))
day = int(input("Enter a day (in numeric): "))
year = int(input("Enter a 2-digit year: "))
# now check if the month times day equals the year:
if month * day == year:
print("The date is magic")
else:
print("The date is not magic")
Numa máquina térmica uma parte da energia térmica fornecida ao sistema(Q1) é transformada em trabalho mecânico (τ) e o restante (Q2) é dissipado, perdido para o ambiente.
sendo:
τ: trabalho realizado (J) [Joule]
Q1: energia fornecida (J)
Q2: energia dissipada (J)
temos: τ = Q1 - Q2
O rendimento (η) é a razão do trabalho realizado pela energia fornecida:
η= τ/Q1
Exercícior resolvido:
Uma máquina térmica cíclica recebe 5000 J de calor de uma fonte quente e realiza trabalho de 3500 J. Calcule o rendimento dessa máquina térmica.
solução:
τ=3500 J
Q1=5000J
η= τ/Q1
η= 3500/5000
η= 0,7 ou seja 70%
Energia dissipada será:
τ = Q1 - Q2
Q2 = Q1- τ
Q2=5000-3500
Q2= 1500 J
Exercicio: Qual seria o rendimento se a máquina do exercicio anterior realizasse 4000J de trabalho com a mesma quantidade de calor fornecida ? Quanta energia seria dissipada agora?

Answer:
It depends, though I think it is NOT THAT EASY. If you are logged into your school account on your personal device and also logged into the browser with your school account, they will be able to track your activity. That being said, your school will not have access to your personal account search history.
Answer: they always will have a different thinkage from others
Explanation:Some people need actual in person learning for better grades it also keeps them from getting distracted easily, they have different brains in everyone in the world everyone thinks, acts and talks in different ways some people dont need in person school because they would rather be online wich are both ok so yes they do bond together online but better in person.
The answer to this question is true
