If a radioactive decay produced 2. 05 × 1011 j of energy, how much mass was lost in the reaction?
1 answer:
The mass lost in the reaction is 0.227 × Kg
The energy that is released during a nuclear reaction can be related to the mass lost using the Einstein equation.
E = m by Einstein demonstrates that matter and energy are only two different manifestations of the same thing. It also demonstrates how much energy (E) can fit into a relatively small mass (m) of matter. Nuclear processes convert matter into energy, yet the combined amount of mass and energy remains constant.
Given that;
E = Δ
Δm =
Δm = 2. 05 × 10^11 J/( 3 × 10^8)^2
Δm = 0.227 × Kg

Answer:
Distance of the object from eye is approx 4.52 m
Explanation:
As we know that the object subtend a small angle on both the eyes which is given as
now we know that the distance between two eyes is given as
d = 7.50 cm
so we have
so here the radius is same as the distance from eye while arc is the distance between two eyes
so we have
