In some lakes, the fish are contaminated with methylmercury. As a member of the Department of Environmental Quality, you have been assigned the job of developing an "advisory" for adult males to limit consumption of fish from these lakes. The advisory will be in terms of a recommended limit on the number of fish meals per unit of time. You must determine the unit of time, which is one per day, or one per week, or one per month. In addition to the EPA recommended values for estimating intake, use 1 x 10-6 for the fraction ingested, a 30-year exposure duration, and a 30-year averaging time to estimate the chronic daily intake. Your superiors have set a hazard index of 0.10 as a matter of policy. The RfD for methylmercury is 1 x 10-4 mg/kg-day.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

joke:

h o h o hope you have a merry christmas!

i think its c if i'm wrong
