Answer: Dust released in the air could be radioactive.
Explanation:
Uranium is a radioactive element. It decays naturally to attain stability. While mining, the dust displaces into the air causing not only harm to environment but for the workers as well. The released in the air could be radioactive which would be inhaled posing threat for lung cancer.
Thus, the correct answer is dust released in the air could be radioactive is a concern about mining Uranium.
Answer:
> The amount of heat required to melt ice and raise the temperature of water T o C T^oC ToC is Q = m L f + m c Δ T Q=mL_f+mc\Delta T Q=mLf+mcΔT Here m = 1.5 k g m=1.5 kg m=1.5kg L f = 3.33 ∗ 1 0 5 J
Answer:
the sum of potential and kinetic energy
Explanation:
Mechanical energy is found in machines and humans.It is a sum of kinetic energy and potential energy.Mechanical energy is constant
