Answer:
They all hit at the same time
Explanation:
Let the time of flight is T.
The maximum height is H and the horizontal range is R.
The formula for the time of flight is
..... (1)
Te formula for the maximum height is
.... (2)
From equation (1) and (2), we get
here, we observe that the time of flight depends on the maximum height and according to the question, the maximum height for all the three balls is same so the time of flight of all the three balls is also same.

Answer:
stress
Explanation:
Common causes of chronic insomnia include: Stress. Concerns about work, school, health, finances or family can keep your mind active at night, making it difficult to sleep.

Answer:
Explanation:
Solar energy production encompasses several power sources, both passive and active. It’s important to differentiate among the different types of solar energy production systems since it’s not uncommon for the average homeowner to confuse them. We’ll start with a diagram of solar energy hitting the earth surface.
Then we’ll present diagrams and discuss photovoltaic solar, solar hot water, and concentrated solar power. The easiest way to think about these is: am I using solar energy to heat water (solar hot water and CSP) or am I converting sunlight directly into electricity (photovoltaic cells)?
Answer:
As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.
