Answer:
The decay process started with 100 radioactive atoms.Eventually all 100 atoms will decay to a stable form. The graph approaches 100 because that is the maximum number of stable atoms that can form

Answer:
a. 2.5 X 10^-1
Explanation:
First of all we shall calculate the resistance of the bulb of 75W , 240 V .
power = V² /R , V is potential and R is resistance
75 = 240²/ R
R = 240²/ 75
= 768 ohm .
Now this bulb is used with 120 V
current = 120 / 768
= .15625 A
power = V X I
potential x current
= 120 x .15625
= 18.75 W.
comparing it with 75 W
the ratio
18.75 / 75
= 2.5 x 10⁻¹.
Answer:
it gives off a range of electromagnetic radiation of shorter wavelengths.
