You have a 35X objective lens in place, and the numerical aperture of the objective lens is 0.75. The numerical aperture of the
1 answer:
Answer:
350x
Explanation:
In a microscope the objective has higher magnification than the eyepiece so, this is a microscope
The magnification of a microscope is given by the product of the magnifications of the eyepiece and and the objective.
Objective lens magnification = 35x =
Eyepiece magnification = 10x =
Total magnification
Total magnification is 350x

Answer:
a. The free body diagram for this object has been attached. It shows all the forces acting on the body at rest, including the friction force in the opposite direction to sliding of the object (assume it's left to right).
b. Since the object is in contact with the surface, there is a normal force acting on both of them and is equal to the weight exerted by each. This perpendicular force is defined by Newton's second law of motion.
c. The force of friction always acts in a direction opposite to the direction of motion of the body. F = mg ('a' for acceleration is replaced by 'g' gravity because acceleration in this case is just gravity).
Hope that answers the question, have a great day!
