Answer:
The answer is option E
Explanation:
The particles vibrate in a perpendicular direction with respect to the wave motion
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:
7.89 7.91
Explanation:
The ranges of measurement lie between 7.92-0.05 and 7.92+0.05
7.87g and 7.97g
Answer:
2.52 m/s
Explanation:
When the man takes a step, his foot is stationary while his body revolves around it. At the point when his body is directly above his foot, there will be no normal force at his maximum speed.
Sum of the forces in the radial direction:
∑F = ma
mg = m v² / r
g = v² / r
v = √(gr)
Given that r = 0.650 m:
v = √(9.8 m/s² × 0.650 m)
v = 2.52 m/s
