Since a typical smelt has 1.04 ppm of PCB is great lakes. So
the amount of PCB in a smelt in great leak can be calculated by multiplying the
mass of smelt by the pcbs present in a smelt
225 g * ( 1.04/100000) = 2.34 x10^-4 g pcbs
Answer:
answer is attached in the figure below hope it helps please mark it as brainlist
First we need to write down heat capacity for water which is constant.
cp=4186 J/(kg*K)
The equation for Energy that we will be calculating is:
E=cp*m*T
where m is mass and T is absolute temperature (273,15 + 60 in this case). Replacing all the values in equation we get:
E = 4186*100*333,15 = 139 456 590 J
Answer:
<h2>3 kg </h2>
Explanation:
The mass of the ball can be found by using the formula

f is the force
a is the acceleration
We have

We have the final answer as
<h3>3 kg</h3>
Hope this helps you
