Answer:
option a is correct answer i.e. d = 1.6 mm
Explanation:
From conservation principle
force by jet = force required to hold the jet
force by the jet is written as
force required to hold the jet = 8N
we know that mass flow rate is given as
substituting value to get required diameter of the nozzle
d = 1.6 mm
The statement about (12+x) that is true is that A.The expression (12+x) is a factor that represents the total number of pillows the artisan makes on Monday and Tuesday.
<h3>What is an expression?</h3>
An expression is simply used to show the relationship between the numbers or variables illustrated.

Answer:
a) The difference in mercury levels in the manometer is 2 centimeters.
b) The gage of the gas is 2.670 kilopascals.
Explanation:
a) Pressure in gases is absolute. A manometer helps to determine the hydrostatic difference between pressure of the gas () and atmospheric pressure (), both measured in pascals. A kilopascal equals 1000 pascals and 1 meter equals 100 centimeters. That is:
(1)
Where:
- Density of mercury, measured in kilograms per cubic meter.
- Gravitational acceleration, measured in meters per square second.
- Difference in mercury levels, measured in meters.
If we know that , , and , the difference in mercury levels in the manometer is:
The difference in mercury levels in the manometer is 2 centimeters.
b) The gage pressure is the difference between gas pressure and atmospheric pressure: (, )
(2)
The gage of the gas is 2.670 kilopascals.
Answer:
20 years
Explanation:
You do 2,000,000 ÷ 100,000 but you can simplify that to 20 ÷ 1 = 20
During those 20 years, the profits you earn will be 80,000 since when you do 2,000,000 x 0.04 but you can simplify that to 20,000 x 4 getting 80,000 and that quite doesn't reach 100,000 dollars
Can u be more clear with the question plsss?
