Answer:
time is 5.973826 sec
Explanation:
Given data
diameter D = 6.0 mm 6× m
separated d = 0.010 m
distance (dis) 185 m
speed s = 16 m/s
wavelength = 550 nm = 550 m
to find out
How much time passes
solution
we know that for resolution we use Rayleigh's Criterion i.e
θ = 1.22 wavelength / diameter = separated / distance 1
we calculate distance 1 by put value wavelength, diameter and separated
distance 1 = diameter × separated / 1.22 wavelength
distance 1 = 6× × 0.010 / 1.22 × 550 ×
distance 1 = 89.418778
so time will be i.e = distance (dis) - distance 1 / speed
time = ( 185 - 89.418778) / 16
time = 5.973826 sec
time is 5.973826 sec
Answer:
The car's initial velocity is 195.96 m/s
Explanation:
Given;
the length of the mark, x = 9.6 km = 9600 m
acceleration of the car, a = -2 m/s²
Apply the kinematic equation below
v² = u² + 2ax
where;
v is the final velocity = 0
u is the initial velocity
simplify the equation and you will obtain;
0 = u² + 2ax
0 = u² + 2(-2)(9600)
0 = u² - 38400
u² = 38400
u = √38400
u = 195.96 m/s
Therefore, the car's initial velocity is 195.96 m/s
Answer:
2. the force of the stone's gravity polling up on the Earth
Explanation:
As we apply the force on the stone, the acting gravity on the stone resists as a reaction force. But that also depends upon the angle of force applied. There will be less force required on the horizontal component than vertical relative to gravity. But the force of friction aided by gravity always resists as a reaction force.
