If the grade of the ore is 37.3% nickel, then the unknown quantity to get 10 grams of nickel is 0.373 x = 10 grams or x = 10/0.373=26.8 grams or 0.0268 kg needed to dig up to recover the 10 grams of nickel. At this grade of ore, 1 kilogram would yield 373 grams of nickel.

1. Which of the following statements is a consequence of the equation E=MC2
finlep [7]

Answer:

D. All of the above​

Explanation:

E = MC² is a common equation in physics.

E is energy

M is mass

C is the speed of light

The law was stated by Albert Einstein.

  • From this law, it was shown that energy is released when matter is destroyed.
  • Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
  • Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
  • Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.

The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of 8.1% per day. f
Elanso [62]
The general equation for radioactive decay is;
N = N₀e^(-λt)
x - decay constant (λ) - rate of decay 
t-  time 
N - amount remaining after t days , since we are calculating the half life, amount of time it takes for the substance to to be half its original value, its N₀/2
N₀ - amount initially present 
substituting the values 
N₀/2 = N₀e^(-0.081t)
0.5 = e^(-0.081t)
ln (0.5) = -0.081t
-0.693 = -0.081t
t = 0.693 / 0.081 
  = 8.55
half life of substance is 8.55 days
