If a radioactive isotope that was injected into your bloodstream has a half-life of 5 hours, how many hours do you have to wait
deff fn [24]

Answer:

Total time = 20 hours

Explanation:

Half life is the amount of time it takes for a substance to decay tohalf of it's original amount.

Half life = 5 hours.

We have to obtain the number of half lives to get the time required.

1st half life = 1/2

2nd half life = 1/4

3rd half life = 1/8

4th half life = 1/16

So ffour half lives.

Total time = number of half lives * Time of half life

Total time = 4 * 5

Total time = 20 hours

The current in a hair dryer measures 11 amps. The resistance of the hair dryer is 12 ohms. What is the voltage?
Valentin [98]

Voltage is given by the formula

V = IR (Ohms law)

where V is the Voltage

I is the current

and R is the Resistance

Here it is given that the current is I=11

Resistance is R =12

so plugging this in the formula

V = IR

V= 11 * 12

V= 132 Volts

So the Voltage for the given dryer is 132 Volts
