Hello, for this exercise, consider the formula:
Considering that the difference in the temperature is 0.284°C, and the given molality by:
Now, solving for 
, we get:
Best regards.
Answer:9.18 m/s
Explanation:
The average speed for the entire trip is found ......total distance/total time. Remember r*t=d, so divide both sides by t and get r = d/t.
So the cyclist went 800+500+1200 m = 2500 m for total distance.
10t =800 leads to t=80 sec
5t=500 leads to t=100 sec
13t = 1200 leads to t = 92.3 sec
total time is 272.3 sec
Average speed for the entire trip is 2500 / 272.3 = 9.18 m/s
Answer:
As estrelas produzem a sua energia por um mecanismo chamado fusão nuclear. Nesse processo dois elementos simples se fundem para produzir um elemento mais pesado, liberando muita energia. ... Neste caso ocorre exatamente o contrário da fusão: Átomos muito pesados (como o Urânio) são quebrados, liberando energia.
Answer:
Explanation:
Pascal(Pa) : It is the SI unit of pressure.It is equal to 1 Newton per meter square(Pa =
)
is the Unit of Force(Newton=N)
<u>Calculation,</u>
It is required to convert 
to 
only, Pa is same in both so no need to alter Pa.
1 m = 1000 mm (see the image)
And,
1 mm = 0.001 m
(Squaring both side)
So,
