Answer:
Methane
Explanation:
Because carbon dioxide is wrong and i just got a 70 percent cause someone thought it was carbon dioxide but it's definitely not
Answer:
IMA = 2
Explanation:
Given the following data;
Resistance gear = 54 teeth
Effort gear = 23 teeth
To find the ideal mechanical advantage (IMA);
IMA = number of teeth on the resistance gear/number of teeth on the effort gear
Substituting into the equation, we have;
IMA = 54/23
IMA = 2.35 ≈ 2
Therefore, the ideal mechanical advantage (IMA) of this two-gear system is 2.
Becuase for sound to happen you need air, And there is no oxygen is space.
Answer:
This question is an example of Boyle's gas law which states that the pressure of a given mass of a gas is inversely proportional to its volume at a constant temperature. The formula for this gas law is:
P1·V1 = P2·V2
P1 = initial pressure = 1.7 atm
V1 = initial volume = 4.25 L
P2 = final pressure = 2.4 atm
V2 = final volume = ?
Rearrange the formula to isolate V2. Substitute the known data and solve.
V2 = P1·V1/P2
V2 = 1.7 atm·4.25 L/2.4 atm = 3.0 L to two significant figures
The new volume will be ~3.0 L.
