Can anyone me with these questions ? ?

1.u are given your formula as P=j over s

so ;1.2000 j over I = 2000w

      2.5000j over 5s = 1000w

      3.1,300j over 13s =100w

I aint so sure but u can take a shot..and please inbox me for futher details

dude, this is hard lol : ))

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
