A police car waits in hiding slightly off the highway. A speeding car is spotted by the police car traveling at speed s = 27.6 m
andriy [413]

Answer:

t=\frac{2s}{a}=25.56s

Explanation:

The distance traveled by the speeding car will be d_s=st, where s=27.6m/s.

The distance traveled by the police car will be given by the formula:

d=v_{0}t+\frac{at^2}{2}, where a=2.16m/s^2 and v_0=0m/s since it departs from rest, thus having d=\frac{at^2}{2}.

The police car will reach the speeding car when those distances are the same, or s=d, so we will have:

st=\frac{at^2}{2}

Which means:

t=\frac{2s}{a}

This is the expression asked, but we can use our values:

t=\frac{2s}{a}=\frac{2(27.6m/s)}{(2.16m/s^2)}=25.56s

What is the correct equation for calculating the average atomic mass for 3 isotopes? (pls be 100%of your answer pls no guessing)
mariarad [96]

<u>Answer:</u>

<em>The correct equation for measuring the average microscopic weight  for 3 isotopes is multiply the rate of abundance by each weight and add them.</em>

<u>Explanation:</u>

To calculate the average microscopic mass of element using weights and relative abundance we have to follow the following steps.

  • Take the correct weight of each isotope (that will be in decimal form)
  • Multiply the weight of each isotope by its abundance
  • Add each of the results together.

<em>This gives the required  average microscopic weight of the three isotopes.</em>
