Answer:
The family would not have hot water unless they were to heat the the water. They would have to depend on the stove in order to survive by heating the house to say alive and not freeze. They would also have to depend on the stove to get hot water to do any, but if the sun goes away for too long and everything starts to die then they will have to use what food and wood that they have in order to survive.
Explanation:
Frequency is defined as the number of repetitions of waves occurring in 1 second. The frequency heard by the man as the ambulance move toward him will be greater than 450 Hz.
<h3>
What is the frequency ?</h3>
Frequency is defined as the number of cycles completed in 1 second. Frequency is given by the formula as,

As the formula shows frequency is inversely proportional to the time that shows if the time is decreasing frequency will increase and vice versa.
In the above case, the ambulance is moving toward the men. So that the time to meet up is decreased that's why the frequency will be greater than the initial frequency from the siren.
Hence the frequency heard by the man as the ambulance move toward him will be greater than 450 Hz.

Answer: The domain that is aligned with the applied field will grow, while the domain that is oppositely aligned to the magnetic field will shrink, this is because permanent magnets produces their own magnetic field.
Answer:

Explanation:
If we express all of the cordinates in their rectangular form we get:
A = (1404.77 , 655.06) m


Since we need C to be (0,0) we stablish that:

That way we make an equation system from both X and Y coordinates:


Replacing values:
With this system we can solve for both Db and Dc and get the answers to the question:


Terminal velocity is caused by friction between an object and the atmosphere, causing it to only go so fast. If there is no atmosphere, there is no friction between the object, so it will accelerate forever.
