Answer:
When a baseball is pitched, hit and flies in the air, one or more of the physical principles formulated over 300 years ago by Sir Isaac Newton act on it. Folklore tells how the mathematician and physicist first realized the law of gravity while observing a falling apple. Had Newton watched a baseball game instead, he might have formulated all three laws of motion by the seventh-inning stretch.

Answer:
Explanation:
The corona is in the outer layer of the Sun's atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun's surface. ... In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated.
The chromosphere ("sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. Its rosy red color is only apparent during eclipses. The chromosphere sits just above the photosphere and below the solar transition region.
The photosphere is the visible "surface" of the Sun. The Sun is a giant ball of plasma (electrified gas), so it doesn't have a distinct, solid surface like Earth. ... The photosphere is much cooler than the Sun's core, which has a temperature well above 10 million degree
And thats all i know
Net force = Pull force - Friction (Opposing force) = 700 - 215 = 485 N
The proton would be 2 and d a part of 1 then calculate that hope this helped
Explanation:
It is given that,
The total mass of the wagon, rider and the rock is 99 kg
The mass of the rock is 0.261 kg.
The initial speed of the wagon, u = 0.519 m/s
Speed of the rock, u' = 15.9 m/s
(a) Let v is the speed of the wagon after the rock is thrown directly in forward direction.
The momentum will remain constant. Using the conservation of momentum as :
v = 0.22 m/s
(b) Let v' is the speed of the wagon after the rock is thrown directly in opposite direction, u' = -15.9 m/s
v' = 0.304 m/s
Hence, this is the required solution.
