Answer:
#See solution for details.
Explanation:
#The commutative property of multiplication tells us that it doesn't matter in what order you multiply numbers. The formula for this property is a * b = b * a:
![40\times32\times10\times 25=320,000\\\\25\times10\times32\times 40=320,000\\\\10\times32\times25\times 40=320,000\\\\32\times25\times40\times 10=320,000](https://tex.z-dn.net/?f=40%5Ctimes32%5Ctimes10%5Ctimes%2025%3D320%2C000%5C%5C%5C%5C25%5Ctimes10%5Ctimes32%5Ctimes%2040%3D320%2C000%5C%5C%5C%5C10%5Ctimes32%5Ctimes25%5Ctimes%2040%3D320%2C000%5C%5C%5C%5C32%5Ctimes25%5Ctimes40%5Ctimes%2010%3D320%2C000)
Hence, the product of the four numbers remains 320,000 irrespective of their order.
Answer:
a) 24 kg
b) 32 kg
Explanation:
The gauge pressure is of the gas is equal to the weight of the piston divided by its area:
p = P / A
p = m * g / (π/4 * d^2)
Rearranging
p * (π/4 * d^2) = m * g
m = p * (π/4 * d^2) / g
m = 1200 * (π/4 * 0.5^2) / 9.81 = 24 kg
After the weight is added the gauge pressure is 2.8kPa
The mass of piston plus addded weight is
m2 = 2800 * (π/4 * 0.5^2) / 9.81 = 56 kg
56 - 24 = 32 kg
The mass of the added weight is 32 kg.
