Two identical drops with radius 2mm join to form a bigger drop. evaluate the lost or gained surface energy given that the surface tension of water is 0.72N/m² e1=4.5×10^-6 joules
e2=9.0510×10^-6 joules

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
