perpendicular to the wave motion.
Heat can be transferred from one place to another by three methods:
conduction in solids,
convection of fluids (liquids or gases),
radiation through anything that will allow radiation to pass.
Explanation:
The angle of the handle relative to the horizontal is 35°. The angle of the ramp to the horizontal is 7°. So the angle of the handle relative to the ramp is 28°.
cos 28° = 50 / F
F = 50 / cos 28°
F = 56.6 lbs
the object distance of both lenses are positive.
