Calculate the change in impulse of a .7-kg soccreball at rest that gets kicked and is going 27m/s What is the force acting on the ball if the change in speed took.25?

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.

c)as speed changes, wavelength and frequency change.

everything changes!

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

i think the answer is a and b

i wish you luck
