<h3><u>Answer;</u></h3>

<em>People with asthma </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Air pollution is a type of pollution that occurs when harmful materials or substances are released to the atmosphere.</u></em> This includes excessive gases, biological molecules and other harmful materials.= such as smoke and dust particles.
  • <u><em>Air pollution has a number of negative effects on human health which includes, respiratory diseases, the cancer of the lungs and heart diseases among others.</em></u>
  • <em><u>Air pollution affects those individuals with asthma the most </u></em>as they already have breathing problems when exposed to various allergens. These <em><u>individuals are at higher risk from breathing the small particles in the air which may make their case worse</u></em>.

Answer:

The correct answer is option D, people with asthma

Explanation:

Small air particles in the atmosphere enhances the problem of asthama. These minute particle enter into the lungs through nose or mouth thereby reducing lung function and causing more frequent asthma attacks. Ozone in the air also triggers asthama as it causes irritation in the lungs and airways. Ozone also reduces lung function and causes difficulty in breathing

Answer:

Conduction, convection, and radiation

Explanation:

Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.

Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.

A 0.12 g honeybee acquires a charge of +24pC while flying. The earth's electric field near the surface is typically 100 N/C, dow
shusha [124]

Answer:

150000000

\dfrac{F_e}{F_g}=0.00000203873598369

49050000 N/C

Explanation:

q = Charge = 24 pC

m = Mass of honeybee = 0.12 g

E = Electric field = 100 N/C

g = Acceleration due to gravity = 9.81 m/s²

1\ C=6.25\times 10^{18}\ electrons

Number electrons is

n=24\times 10^{-12}\times 6.25\times 10^{18}\\\Rightarrow n=150000000

The number of electrons added or removed was 150000000

Force is given by

F_e=Eq\\\Rightarrow F_e=100\times 24\times 10^{-12}\\\Rightarrow F_e=2.4\times 10^{-9}\ N

The ratio is

\dfrac{F_e}{F_g}=\dfrac{2.4\times 10^{-9}}{0.12\times 10^{-3}\times 9.81}\\\Rightarrow \dfrac{F_e}{F_g}=0.00000203873598369

The ratio is \dfrac{F_e}{F_g}=0.00000203873598369

Balancing the forces we get

Eq=mg\\\Rightarrow E=\dfrac{mg}{q}\\\Rightarrow E=\dfrac{0.12\times 10^{-3}\times 9.81}{24\times 10^{-12}}\\\Rightarrow E=49050000\ N/C

The electric field required is 49050000 N/C
