German physicist werner heisenberg related the uncertainty of an object's position (δ to the uncertainty in its velocity (δ δ≥ℎδ where ℎ is planck's constant and is the mass of the object. the mass of an electron is 9.11×x10−31 kg. what is the uncertainty in the position of an electron moving at 8.00×106 m/s with an uncertainty of δ=0.01×106 m/s?

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,
