If Mrs. Ransoms calculated average speed at the 5 m marker is a m/s and 6 m/s at the 10 m marker, and it took 13 s to cover the distance, what is Mrs. Ransoms average acceleration?​

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.

i think the answer is a, hope this is right, that would be my best guess.

so easy. just google the electromagnetic waves and it’ll pop up.
