Answer:

The distance is 88 units

speed = 11 units per minute

Step-by-step explanation:

To find the distance, take the second point and subtract the first point

-100 - (-12)

-100+12 = -88

Distance is the number (direction is positive or negative)

The distance is 88 units

To find the speed, take the distance and divide by the time

speed = 88 units / 8 minutes

speed = 11 units per minute

Answer:

Step-by-step explanation:

Difference between 12 and 100 is 88.

Too, 8 minutes to travel 88 units

88/8 = 11, so the bugs average speed was 11

Alenkasestr [34]

Answer: 693 years

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

$A(t) =A_0e^{kt}$

k = rate constant

t = time taken for decomposition = 1

$A_0$ = Initial amount of the reactant

$A_t$ = amount of the reactant left = $A_0-\frac{0.1}{100}\times A_0=0.999A_0$

$0.999A_0=A_0e^{k\times 1}$

$0.999=e^k$

$k=-0.001year^{-1}$

for half life : $t=t_\frac{1}{2}$

$A_t=\frac{1}{2}A_o$

Putting in the values , we get

$\frac{1}{2}A_0=A_0e^{-0.001\times t_\frac{1}{2}$

$t_\frac{1}{2}=693 years$

Thus half life of this isotope, to the nearest year is 693.
