Answer:
The magnitude of the lift generated by the wings of the airplane is 130,340 N.
Explanation:
Given;
mass of the airplane, m = 13,300 kg
speed of the airplane, v = 560 km/h = 155.56 m/s
The magnitude of the lift generated by the wings of the airplane is calculated as;
Therefore, the magnitude of the lift generated by the wings of the airplane is 130,340 N.
Answer:
Desiree should collect data, which may support or refute her hypothesis.
Explanation:
The next step Desiree must take is to collect data which might likely support or refute her hypothesis.
This is usually done by carrying out experiments or field studies.
- The scientific method provides the steps through which knowledge of science is investigated.
- It usually starts with observation.
- After an observation is made, a scientific question is asked.
- This leads to the development of hypothesis.
- Then, experiments are carried out and data collect to either bolster the claim or refute it.
- Interpretation follows and conclusion is draw.
Answer:
the mass of the air in the classroom = 2322 kg
Explanation:
given:
A classroom is about 3 meters high, 20 meters wide and 30 meters long.
If the density of air is 1.29 kg/m3
find:
what is the mass of the air in the classroom?
density = mass / volume
where mass (m) = 1.29 kg/m³
volume = 3m x 20m x 30m = 1800 m³
plugin values into the formula
1.29 kg/m³ = <u> mass </u>
1800 m³
mass = 1.29 kg/m³ ( 1800 m³ )
mass = 2322 kg
therefore,
the mass of the air in the classroom = 2322 kg
