The formula for solving the inertia (I) is I=mr² where "m" represents the mass of an object and "r" represents the perpendicular distance to the rotation axis.
item 1= 100 kg rock
Item 2= 5kg book
item 3= 60kg person
item 4=2000kg car.
The answer is the last item which is a 2000kg car.
Answer:
If you hold the temperature of an ideal gas constant, what happens to its volume when you triple the pressure? For T fixed, P is proportional to 1/V or V is proportional to 1/P. Tripling P reduces V to 1/3. ... If T is constant, the speeds of the average speeds and kinetic energy of the atomic particles remain constant.
I hope this helps!
Answer;
= 2.34 x 10^-4 g pcbs
Explanation;
-A typical smelt has 1.04 ppm of PCB is great lakes.
Therefore;
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
The Answer that makes the most sense is C.
