Answer: The angle of resolution =47.05°
Explanation:
The angle of resolution represents the resolve power and precision of optical instruments such as the eye, camera and e en a microscope. It is given by the equation:
Sin A = 1.220(W÷D)
Sin A= 1.220(300÷500)
Sin A = 1.220(0.6)
Sin A = 0.732
A= Sin^-1 0.732
A= 47.05°
Answer:
The correct answer is spin faster.
Explanation:
The angular momentum or kinetic moment is a physical magnitude, rotational equivalent of the linear momentum and represents the amount of rotational movement of an object. It is a vector quantity that characterizes the inertia properties of a body, which rotates in relation to a certain point. It is found in the three mechanics (classical, quantum and relativistic mechanics). In the International System of Units the angular momentum is measured in kg · m² / s. This magnitude plays a role similar to the linear moment in the translations with respect to the rotations.
Answer:
433.15K
Explanation:
(320°F − 32) × 5/9 + 273.15 = 433.15K
Answer:
by finding melting and boiling points
Explanation:
Answer:
4.7m
Explanation:
Given parameters:
Mass of the book = 1kg
Gravitational potential energy = 46J
Unknown:
Height of the shelf = ?
Solution:
The potential energy is due to the position of a body above the ground.
Gravitational potential energy = mgh
m is the mass,
g is the acceleration due gravity = 9.8m/s²
h is the height which is unknown
46 = 1 x 9.8 x h
h = 4.7m
