Explanation:
To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light
Uranium-238 undergoes alpha decay. Therefore, uranium-238 will
A. Remain stable
B. Stay the same element
C. Release charged particles and no energy
<u>D. None of the above</u>
The actual answer is that it will change into a different element altogether.
Answer:
(c) 2
Explanation:
Heat transfer across the walls due to conduction is given by:
where,
q = heat transfer rate
K = thermal conductivity
A = Area
ΔT = change in temperature
L = thickness
For wall A:
For wall B:
Because the change of temperature and area of walls are the same. Dividing both terms:
using values given in the question:
Therefore, the correct answer is:
<u>(c) 2</u>
Rain is considered a precipitate. Along with: drizzle, sleet, snow and hail.
