Hi Maria.
The formula for finding the mass of the object is M = F/A, or the force divided by the acceleration. Since we have our force and acceleration, we are ready to solve!
M = 350 / 10.
M = 35.
The unit of measurement for mass is kg, so your answer is going to be
35 kg.
I hope this helps!
Answer:
2412 psi is the pressure of the gas mixture in the tank.
Explanation:
Pressure of the helium gas = 1,906 psi
Volume of the helium gas = 7.25 L
Pressure of the oxygen gas = 506 psi
Volume of the oxygen gas = 7.25 L
After mixing both gases in a container with volume 7.25 L at with constant temperature.
Since, the temperature and volume remained constant, pressure becomes directly dependent on moles of gases.So, when we mix gases together the moles of gases will also add and along with that pressure of individual gas will also get added to give total pressure of the mixture in a tank.
Total pressure = pressure(Heluim)+pressure(oxygen)
![P_{total}=1,906 psi+506 psi=2,412 psi](https://tex.z-dn.net/?f=P_%7Btotal%7D%3D1%2C906%20psi%2B506%20psi%3D2%2C412%20psi)
2412 psi is the pressure of the gas mixture in the tank.
let the length of the beam be "L"
from the diagram
AD = length of beam = L
AC = CD = AD/2 = L/2
BC = AC - AB = (L/2) - 1.10
BD = AD - AB = L - 1.10
m = mass of beam = 20 kg
m₁ = mass of child on left end = 30 kg
m₂ = mass of child on right end = 40 kg
using equilibrium of torque about B
(m₁ g) (AB) = (mg) (BC) + (m₂ g) (BD)
30 (1.10) = (20) ((L/2) - 1.10) + (40) (L - 1.10)
L = 1.98 m
If one bulb goes out then all the others won't light up because electricity will be cut off. It's a disadvantage because in a parallel circuit if one bulb burns out all the others will still be on because they won't be affected. I hope I've helped you ☺
In PBL teaching, an individual student will teach a particular topic to the group meaning the content of information taught will be dependent on the motivation of the individual students. Traditional courses tend to emphasise the foundations in biomedical knowledge required in medicine earlier on.
