Answer: the first is gravity
the second is Newton’s 3rd Law of Motion
Hope this helped :)
Explanation:
the new momentum would be 40000 units as momentum = mass × velocity
Answer:
force on larger piston = <em> </em>
Explanation:
we label the pistons as piston A and piston B
small piston A:
area = a
force = f
large piston B:
area = A
force = ?
<em>Pascal's law of pressure state that the pressure delivered to a liquid is transmitted undiminished to every portion of the fluid.</em>
we know that pressure = force ÷ area
pressure of piston A = 
pressure of piston B = 
obeying Pascal's law, the system pressures must be equal. Therefore

force on large piston (B) = F =<em> </em>
Answer:
false
Explanation:
I'm pretty sure that's false.
The speed of a beam of light will appear the same to all observers.
<h3>Speed of light:</h3>
The exact distance that light travels in a vacuum in a second is 299,792,458 meters (983,571,056 feet). This is roughly 186,282 miles per second, or "c," the symbol for light speed in mathematics.
According to Einstein's theory of special relativity, an object (such as a single photon of light) cannot appear to move faster than the speed of light. This physical rule is not broken by Nemiroff's experiment since the laser pointer emits a stream of photons rather than a single photon.
Nothing can move faster than light in a vacuum, according to one of physics' most revered rules. However, in a recent experiment, this speed restriction was broken when a laser pulse traveled at more than 300 times the speed of light.
