Answer:
An example of kinetic energy due to gravity can be a ball held in the air (Kinetic energy is energy an object has because of it's motion.).
Explanation:
With 30degree because incident angle = reflected angle
Answer:
8.87 m/s^2
Explanation:
Acceleration is change in velocity over a change in time
27 to 53 = 26 m/s change in velocity
26 m/s / 3 s = 8.87 m /s^2
Answer:
Uncertainty ΔV = 22.601 x 10^-10
ΔV = 2.2601nv or 2.2601 x 10^9V
Explanation:
from V = kQ/r
Uncertainty in V is given by δV = V square root [ (δQ/Q)^2 + (δr/r)^2]
ΔV = V square root [ (ΔQ/Q)^2 + (Δr/r)^2] .....................(2)
Given that ; Q = 3.2042e−19 C, r = 0.08 m, ΔQ = 1.6021e−21 C, Δr = 0.005 m
Plugging the values given into equation (2)
from ΔV =(kQ/r) square root [ (ΔQ/Q)^2 + (Δr/r)^2]
ΔV = 9 x 10^9 x 3.2042e−19 / 0.08 square root [ (1.6021e−21/ 3.2042e−19)^2 + ( 0.005/0.08)^2]
ΔV = 360.47 x 0.06269 x 10^-10
Uncertainty ΔV = 22.601 x 10^-10
ΔV = 2.2601nv or 2.2601 x 10^-9V
