This is a good question. The short (but less satisfying) answer is: "because the hydrostatic pressure of oil at a certain depth depends on the height of the oil level, measured from that point." So, you can have a tiny amount of oil but arranged in a column that makes it very tall/high and get high pressure, and have same amount of oil spread so that the height is negligible to produce a negligible amount of pressure. The exact formula for pressure is P=r*h*g (r stands for the liquid density, h for height, and g for gravitational acceleration).
The long answer, but much more satisfying, goes through the derivation of this formula. I recommend searching for a good video explaining hydrostatic pressure. (I can't post links).
Deceleration isn't a term in physics; you can have positive acceleration which is speeding up and negative acceleration which is slowing down
Use newton's law F = ma
a = F/m
<span>Alcohol begins to affect your brain when it crosses the blood-brain barrier. After this, it acts on the nerve cells and disrupts their communication with each other as well as other body parts. It inhibits the activity of some neural pathways due to which a person starts feeling lethargic, sluggish, and slow-moving.</span>
The easiest way it to stick it to a metallic surface and then apply an increasing force to pull it with a device that measures the force applied, until the magnet disconnects from the surface.
Answer:
We need to perform a condition of balance along a rod in which we can measure distances. Finally, find the weight ratio and measure the weight of one of the masses in order to find the weight of the second.
Explanation:
We need to see this problem using a sketch with a class 1 lever. And some numerical values to understand and how to make the proper calculations.
Let's say that we have a body in the form of a beam 1 meter long, then we put the two masses in each of the ends of the beam under the beam, we place the fulcrum and move up to the beam to obtain a horizontal position when horizontal position is reached the beam will be in balance.
Then we perform a sum of moments around the pivot point or fulcrum since we know the distances, we can find the mass relation in the condition of balance. For this example the ratio corresponds to M1 is 2.33 times heavier than M2.
