d. sudden fall in air pressure affects weather...common man
Answer:
Duhhh... It's d.
Explanation:
B- the sun
C- stars
D- meteoroids
A gem is a stones that is used to make jewelry. A crystal is apure substance that has molecules arranged in "a regular geometric pattern". A gem can also be a crystal, whereas a crystal can not be a gem.
Hope this helps. <3
A hammer and a feather will fall with the same constant acceleration if air resistance is considered negligible. This is a general characteristic of gravity not unique to Earth, as astronaut David R. Scott demonstrated on the Moon in 1971, where the acceleration due to gravity is only 1.67 m/s2.
The acceleration due to gravity is the same for all objects near the surface of the Earth, regardless of their mass. The effect of air resistance may make it appear that the acceleration of a feather is smaller than that of an iron ball.
Acceleration due to gravity refers to the rate at which an object falls toward the Earth under the influence of gravity. The value of acceleration due to gravity varies depending on the location and mass of the object.
In general, the acceleration due to gravity is the same for all objects near the surface of the Earth, regardless of their mass. This means that the acceleration due to gravity of a feather is the same as that of an iron ball. However, due to the difference in air resistance, a feather will experience a much smaller net force compared to an iron ball, which may give the illusion of a slower acceleration.
Therefore, the acceleration due to gravity of a feather is not smaller than that of an iron ball, but the effect of air resistance makes it appear so.

A wave with a large amplitude has a lot of a.vibration b.speed c.energy
Answer:
A high amplitude wave carries a large amount of energy; a low amplitude wave carries a small amount of energy. The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave.
Enjoy.
