Answer:
velocity
acceleration
time taken
air pressure
size of the ball
gravity(gravitational acceleration )
Answer:
Acid is any substance from 0-6
(stomach acid, lemon juice, vinegar, milk, soda, rainwater)
Bases are any substance from 8-14
(egg whites, baking soda, ammonia)
Neutral are 7
(pure water)
Explanation:
* Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.
* Bases feel slippery, change litmus blue, and become less basic when mixed with acids.
Explanation:
Entrepreneurs are not wild risk takers but are instead calculating risk takers. They appear to be risk takers because they see the market differently than the rest of us do. 3. ... Entrepreneurs tend to be optimistic about their chances for success, and usually their optimism is based in reality.
Answer:
24.5 N
Explanation:
The falling object experiences its weight acting downwards and the air resistance in the opposite direction.
The air resistance increases with velocity so there may come a point, depending on the shape of the object and if there is sufficient height, where these 2 forces are equal.
Since the object has no net forces acting on it it will, according to Newton, no longer accelerate but continue with a constant velocity.
This is called Terminal Velocity.
So:
Air resistance = weight

You use the equation wavelength= 4 x length of pipe/ number of the harmonic so your wavelength is 1.45.
