To be honest, there's no sure way to answer that, because you haven't defined your terms and we can't be sure of what j or s might be.
Tell you what I'll do:. I'll assume definitions for j and s, and then I'll answer the question that I invented.
Assume that j stands for Joule, the unit of energy. And assume that s stands for 'second', the unit of time.
Then j/s is the rate of transferring energy or doing work.
Its unit is the Watt, equivalent to 1 Joule per second.
In your system of notation, it would be 'w' .
Please lord thank you please thank you
So we know coefficient of f times normal force is friction. So do 100= .25 times x. Now solve for x. You get 400. So 400 is the normal force. And we know normal force equals weight in these types of problems so the answer is 400
Directly proportional to volume, according to charles’s law
<span>The water is clearer, has higher oxygen levels, and freshwater fish such as trout and heterotrophs can be found. In the middle of the river, the width increases, so do the species of aquatic green plants and algae. Toward the mouth of the river, the water becomes murky from all the sediments that it has picked up upstream.<span>
