Question

If there is 360 grams of radioactive material with a half-life of 8 hours, how much of the radioactive material will be left after 32 hours and is the radioactive decay modeled by a linear function or an exponential function? A) 22.5 grams; linear B) 22.5 grams; exponential C) 45 grams; linear D) 45 grams; exponential

Answer 1

Answer 2

Required formula is
N=N0*e^(-lamda*t)

Answer 3

?

Answer 4

360/4 = 90 considering it is half life then it would be 45

Answer 5

Here
N0=360gram=initial amount of radioactive materials

Answer 6

ok

Answer 7

N=remaining amount of radioactive matetials after 32 hrs

Answer 8

U hv to find out N=?

Answer 9

e means exponential

Answer 10

im lost

Answer 11

Ok

Answer 12

U know an equation
Lamda=0.693/half life

Answer 13

yea

Answer 14

Lamda=?

Answer 15

Half life is given

Answer 16

Half life=8 hrs

Answer 17

360/2=180/2=90/2=45/2=22.5

Answer 18

Just divide by 2 every 8 hours
