9.81 meters per second squared
Answer: 0.5 mm
Explanation: The smallest division that a common ruler has is 1 mm so any measurement taken is approximately accurate to a mm.
Uncertainty of any measuring instrument is the inaccuracy or lost of precision that occur due to its less divisions in an instrument
Uncertainty= Least Count /2
Uncertainty= 1 mm /2
Uncertainty= 0.5 mm
it means that measurement can be 2.3cm ± 0.5mm
Answer:
This is true. objects that have a greater mass has greater interia. which also means objects that have a less mass has also less interia.

i hope this helps!!!
All of the four have rings, but if i'm not mistaken Saturn is the only visible ring.
Hope I helped, a brainleist answer would be highly appreciated!
Answer:
C) 20 m/s
Explanation:
Wave: A wave is a disturbance that travels through a medium and transfers energy from one point to another, without causing any permanent displacement of the medium itself. Examples of wave are, water wave, sound wave, light rays, radio waves. etc.
The velocity of a moving wave is
v = λf ............................ Equation 1
Where v = speed of the wave, λ = wave length, f = frequency of the wave.
Given: f = 2 Hz (two complete cycles in one seconds), λ = 10 meters
Substituting these values into equation 1
v = 2×10
v = 20 m/s.
Thus the speed of the wave = 20 m/s
The right option is C) 20 m/s
