Question

The rate of disintegration of a radio active element at any time t is proportional to its mass at that time. Find the time during which the original mass of 1.5 gm. will disintegrate into its mass of 0.5 gm.

Answer 1

ooooooooooooooooooooooooooooooooooof

Answer 2

Answer:

Δt = 1/k(1.5)

Step-by-step explanation:

Given in the question,

The rate of disintegration of a radio active element is proportional to its mass

so,

Δm / Δt $\alpha$ mass

Δm / Δt = (k)mass

(1.5-0.5) / Δt = k(1.5)

(1) / Δt = k(1.5)

Δt = 1/k(1.5)
