True Car Accidents are the #1 Death of Teenagers. True Seat belts can save lives. This relates to the Third Law of Motion because For every Reaction there is always an equal and opposite reaction. For example if a car hits you with a force of P, then you will move in the opposite direction at the force of P. This also relates to Newton's first Law of motion, Inertia.

Hope this helped! Please Mark as Brainliest! Thanks! :)

The Newton's third law of motion describes that every force has a opposite and equal force. When a car hits a obstacle, passenger's body moves forward due to momentum or inertia. When the passenger moves forward, there would be an equal force from the seat belt that is pushing the passenger back, protecting the passenger.

Energy of fossil fuels is also derieved from solar energy​
Marat540 [252]

Answer:

Explanation:

All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis.for example when  we burn wood to release energy that trees capture from the sun, we burn fossil fuels to release the energy that ancient plants captured from the sun. We can think of this energy as having been deposited in a natural solar power bank over millions of years.

So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!

At which temperature does the motion of atoms and molecules stop?
Scorpion4ik [409]

Answer:

0 Kelvin

Explanation:

Atoms in absolute temperature get approximatelly motionless since 0 Kelvin is -273 degrees Celcius. The kinetic energy of atoms/particles in matter has the possible lowest value ( almost zero), so that there is nothing colder than 0 Kelvin.

A ray is incident on a film of thickness t and the index of refraction n=1.6 at an angle θ = 35 degrees. Find the angle of refra
lidiya [134]

Answer

Given,

refractive index of film, n = 1.6

refractive index of air, n' = 1

angle of incidence, i = 35°

angle of refraction, r = ?

Using Snell's law

n' sin i = n sin r

1 x sin 35° = 1.6 x sin  r

 r = 21°

Angle of refraction is equal to 21°.

Now,

distance at which refractive angle comes out

d = 2.5 mm

α be the angle with horizontal surface and incident ray.

α = 90°-21° = 69°

t be the thickness of the film.

So,

tan \alpha = \dfrac{t}{d/2}

tan 61^0 = \dfrac{t}{2.5/2}

t = 2.26 mm

Hence, the thickness of the film is equal to 2.26 mm.
