you can got help with school .com they have alot of answer
Explanation:
Answer: PE = 800j, KE = 800J
Explanation:
To calculate the potential energy, we use the formula
Potential Energy = Mgh
M = 20kg, g = 10m/sˆ2 , h = 4m
=20 × 10 × 4
=800J
At the maximum height S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2
Using the third equation of motion
vˆ2 = uˆ2 + 2as
= 0ˆ2 + 2 × 10 × 4
vˆ2 = 80
Kinetic Energy (KE) is given by
KE = ½ mvˆ2
= ½ × 20 × 80
=800J
Answer:
The growth of cities has affected the production of food because as more people move into cities, there are more places that are having to be transformed into crops to feed us. We no longer have to grow the food in a nearby area, so this makes it to where cities don’t have to have produce so close to them.
Explanation:
the town takes up space so can't grow as much.
A monopoly occurs when one company has sole control over a product and its production (vertical and horizontal integration are also different factors of monopolies, so you could look those definitions up as well if you would like
