How can human health be affected by changes in air quality?

Physics
1 answer:
Anna11 [10]3 years ago
3 0
Answer: Air quality changes like pollution and can cause problems in humans like heart disease, lung cancer, and other diseases. Air is formed by a certain ratio of Oxygen, Carbon Dioxide, Argon, and others. When this proportion is disturbed, it can also cause humans health problems. EX: The ash clouds of volcanos can cause silicosis (lung impairment).

According to Newton’s first law of motion, what will an object in motion do when no external force acts on it?
KonstantinChe [14]

By definition, we have to:

Newton's first law states that any object will remain in a state of rest or with a uniform rectilinear motion unless an external force acts on it.

Therefore, according to the first law of Newton, if the object is already in motion and has no force acting on it then, it will remain with a uniform rectilinear motion.

Answer:

The object will remain with a uniform rectilinear movement when the external force does not act on it.

Ezekiel pushes a 34 kg sled with 101 N for 8.0 m. How much work did he do on the sled?
Simora [160]

Answer: 810 J

Explanation: work W = F·s = 101 N · 8.0 m = 808 J

Force F = u mg = 101 N in which u is friction constant. Also mass is included in force.

What is the passenger's apparent weight at t=1.0s?
Fittoniya [83]

Answer:

For the complete question provided in explanation, if the elevator moves upward, then the apparent weight will be 1035 N. While for downward motion the apparent weight will be 435 N.

Explanation:

The question is incomplete. The complete question contains a velocity graph provided in the attachment. This is the velocity graph for an elevator having a passenger of 75 kg.

From the slope of graph it is clear that acceleration at t = 1 sec is given as:

Acceleration = a = (4-0)m/s / (1-0)s = 4 m/s^2

Now, there are two cases:

1- Elevator moving up

2- Elevator moving down

For upward motion:

Apparent Weight =  m(g + a)

Apparent Weight = (75 kg)(9.8 + 4)m/s^2

<u>Apparent Weight = 1035 N</u>

For downward motion:

Apparent Weight =  m(g - a)

Apparent Weight = (75 kg)(9.8 - 4)m/s^2

<u>Apparent Weight = 435 N</u>

1. A densidade do nitrogênio nas condições normais de temperatura e pressão é igual a 1,24507 kg/m³. Qual a massa de 200 cm³ de
Levart [38]

Answer:

5.49×10⁻⁴ lbm

Explanation:

Convert volume to m³.

V = (200 cm³) (1 m / 100 cm)³ = 0.0002 m³

Find mass in kg.

m = ρV

m = (1.24507 kg/m³) (0.0002 m³)

m = 0.000249 kg

Convert mass to lbm.

m = (0.000249 kg) (2.205 lbm/kg)

m = 0.000549 lbm

m = 5.49×10⁻⁴ lbm
