The highly energetic gamma particles can penetrate most compounds that stop by other types of radiation. However, lead, steel, or concrete can reduce the high energy of these particles, making them less penetrating.

Hence, Gamma radiation can be stopped by a several inches of lead or steel, or several meters of concrete.

Principle amount = Rs. 29000

Interest = Rs. 10440

Let rate of interest = r%

=> So, time = r years

According to the question,

10440 = 29000 x r x r/100

290 x r x r = 10440

r x r = 1044/29 = 36

r = 6

Hence, the rate of interest = 6% and time = 6 yrs.

We know M1×D1×H1W1 = M2×D2×H2W2 

=> 15×4×1435 = M×8×1050

=> M = 15
