<span>If it stopped spinning completely, you would get 1/2 year daylight and 1/2 year nightime!! During daytime for 6 months, the surface temperature would depend on your latitude, being far hotter that it is now at the equator than at the poles where the light rays are more slanted and heating efficiency is lower. This long-term temperature gradient would alter the atmospheric wind circulation pattern so that the air would move from the equator to the poles rather than in wind systems parallel to the equator like they are now!</span>
Answer:
a) 
b)
Explanation:
First we convert our minutes to hours so we work always in the same units.
Where we used the fact that 1 hour are 60 min, thus the multiplying factor is equal to 1 (not altering the time, just changing the units).
a) On the first part the motorist travels a distance 
, and on the second part he travels 
.
The total displacement is 
b) The average velocity is the relation between the total displacement and the time taken to cover it. Our total time is t=0.6h+0.25h+2.2h=3.05h, thus we have:
Well, first of all, let's not make something complicated ... for which we're missing an important component anyway ... out of something simple. There's more to "velocity" than 'meters per second'. So let's just call that what it is: " Speed ".
Here's what you've told us:
-- Something is moving along a ruler or meter stick.
-- At every instant from time=0 to time=5, its speed was constant at 4 m/s.
-- At time=0, it was located at 6m .
We can calculate:
-- Moving steadily at 4 m/s for 5 seconds, it moved (4 x 5) = 20 meters.
-- If it was located at 6m when time=0, then at time=6, it had advanced
to (6 + 20) = 26 meters.
Increasing the mass of an object increases its momentum.
Explanation:
- Momentum of an object is measured as the quantity of motion done by the object.
- It is calculated using the formula, p = m × v where m is mass of the object and v is the velocity of the object.
- As momentum and mass vary proportionally, as seen in the formula, increasing the mass of an object will also increase its momentum.
Answer:
Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.
