Answer: 6000N/m^2
Explanation:
Weight =1500N
Area =0.5m^2
Pressure =1500/(0.5^2)
=6000N/m^2
Note: Newton is denoted by 'N' (Capital) and use '^' for powers.
Answer:
It is a example of physical change
Answer:
F = 75.49 N
Explanation:
given,
atmospheric pressure Po = 1 atm
Po = 101325 Pa
diameter =3.08 cm,
radius = 1.54 cm
1 cm = 0.01 m
1.54 cm = 0.0154 m
Force = Pressure x area
area = π r²
Force = 101325 Pa x π x 0.0154 x 0.0154
F = 75.49 N
Weight of the heaviest brick that the cleaner can lift is F = 75.49 N
The amount of NOx emission produced by a household is required.
The total amount of NOx the household is responsible for is 91.06 kg.
1 car produces 11 kg of NOx per year.
Natural gas burning produces 4.3 g of NOx per therm.
Electric power plant produces 7.1 g of NOx per kwh.
2 cars will produce
of NOx.
1200 therms of natural gas will produce 
9000 kWh will produce 
Converting all to kg and finding the total amount

The total amount of NOx the household is responsible for is 91.06 kg.
