Answer 1
Answer:

All of the following are long-term risks associated with exposure to secondhand smoke EXCEPT:

A. increased risk of respiratory illness

B. increased risk of lung cancer

C. change in senses

D. increased risk of cardiovascular disease

This is the Correct Answer.
Answer 2
Answer: The answer is D.
Cardiovascular diseases are a result of a sedentary lifestyle and a poor diet. Secondhand smoke is not a risk factor for CV diseases. The other choice except letter D are long term risks associated with exposure to secondhand smoke. A person should stay away from people who are smokers so as not to obtain these possible complications within the body. Air filters in cigarettes are not present in the air which make chemical exposures at a higher level for people who are secondhand smokers compared to smokers themselves.

Answers

Use conservation of momentum.  Check to see if your answer makes sense.  A heavy ball moving right hits a stationary ball.  Afterwards they should both be moving right and the lighter ball should be moving faster.

How much energy is contained in matter with mass of 1 gram (0.001 kilogram)

Answers

The mechanical energy consisting of potential and kinetic energy is:

           0.001 x [ (acceleration of gravity x height) +  (1/2) (speed)² ] .


You want to know how much [ mc² ] there is in 1 gram of mass.

           E = m c² = (0.001) x (3 x 10⁸)² = 9 x 10¹³ joules

That's the energy that a 1,000-watt toaster uses 
in  2,852 years  of continuous toasting.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Hope that helped!

Which explanation of the solar system best fits the observations of the planets and how they orbit the sun?A. The gravity of a large, massive star passing the sun ripped off blobs of material from it that formed the planets

B. The planets formed at the center of a collapsing spinning cloud of gas and dust

C. The sun and planets formed from a collapsing spinning cloud of gas and dust.

D. A comet hit the sun and sent off fragments the became the planets.

I'm pretty sure it's C?

Answers

Answer: C. The sun and planets formed from a collapsing spinning cloud of gas and dust.

Explanation:

The entire solar system was formed from solar nebula. A nebula is a cloud of dust and gases. When this cloud spins and contracts, a protostar is formed. The temperature rises and nuclear fusion kicks in forming a star. The rest of the matter forms planets and other celestial bodies of the star system. Similarly, the Sun was formed in solar nebula from collapsing of spinning cloud of dust and gas.

You're right, Answer C

The dust and gas accumulate to form a solar nebula, which later on creates the star and the planets.
