Volume is amount of space a 3-dimensional takes up or can contain. If the box was full of water, find the volume of the box using
Volume = Length x Width x Height
if the measurements are in inches your answer should be in inches cubed (in^3)
it is desirable for the microscope to be parfocal because then you do not have to refocus the microscope everytime you change objective lenses.
The return flow goes to the right and instead of sea breeze, there's land breeze.
I attached the missing picture.
The force of seat acting on the child is a reaction the force of child pressing down on the seat. This is the third Newton's law. The force of a child pressing down the seat and the force of the seat pushing up on the child are the same.
There two forces acting on the child. The first one is the gravitational force and the second one is centrifugal force. In this example, the force of gravity is always pulling down, but centrifugal force always acts away from the center of circular motion.
Part AFor point A we have:
In this case, the forces are aligned, centrifugal is pointing up and gravitational is pulling down.
Part BAt the point, B situation is a bit more complicated. In this case force of gravity and centrifugal force are not aligned. We have to look at y components of this forces, y-axis, in this case, is just pointing upward.
Part CThe child will stay in place at point A when centrifugal force and force of gravity are in balance:
