<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

Which sentence describes Newton's first law?
Marrrta [24]

\Large{\red{\bf{\blue{\dag} Answer:-}}}

Newton's First Law of Motion :

An object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

Here this statement is best represented by the statement : <em>Unbalanced forces cause an object to move.</em><em> </em>[ option c ]

Newton's 3 laws of motion :-

Newton's First Law of Motion :-

It states that an object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

Ex - (i) We tend to fall backwards while standing in the bus , when it starts suddenly.

(ii) We tend to fall forward while standing in the bus , when it stops suddenly.

Newton's Second Law of Motion :-

It states that the rate of change of momentum is directly proportional to the applied force in the direction of the force . That is ∆p \propto Force .

Ex - (i) When we push car & a truck with same force the car will have Greater acceleration due to less mass . (Imaginary case ).

(ii) We feel easy to push a empty cart than a full cart .

Newton's Third Law of Motion :-

It states that every action has equal and opposite reaction .

Ex - (i) We are able to walk on ground due to Newton's third law of motion .

(ii) When we push wall it also applies equal and opposite force .

what are 3 CHEMICAL REACTIONS that you personally observed over the last 2 weeks. You should only include chemical reactions tha
Allisa [31]

1).  I started up my car.  Gasoline was spritzed into the cylinders, mixed with air, and then exploded with an electrical spark.  As the gasoline vapor instantly burned in the air, several new things were formed that weren't there before, like carbon dioxide, carbon monoxide, water, and oxides of nitrogen.

2).  I left my dinner on the stove a little too long, and it got a layer of crunchy crackly sooty carbon on the bottom. That part of it didn't taste too good.  This isn't exactly something that happens every day, but more often than I'd like it too.

3).  All day, every day, and all night, every night, about 10 or 20 times every minute, I pull air into my lungs.  I keep it there for a while, then I blow it out and pull in some fresh stuff.  The air I blow out has less oxygen and more carbon dioxide in it than it had when I pulled it in.  That's because of the hundreds of chemical reactions going on inside my body, to keep me alive and functioning.  I hope these keep going on for many many more days in the future.

Determine the apple's kinetic energy, KE, the gravitational potential energy of the system, gravity, and the total mechanical en
guajiro [1.7K]

Answer:

7.45

Explanation:

At 3.0 m PE = m*g*3.0, KE = m*g*(4.0 - 3.0)

At 2.0 m PE = m*g*2.0, KE = m*g*(4.0 - 2.0)

At 3.0 m PE = m*g*1.0, KE = m*g*(4.0 - 1.0)

At 0 m PE = 0, KE = m*g*h = total energy = 7.45 J
