In kynematics you describe the motion of particles using vectors and their change in time. You define a position vector r for a particle, and then define velocity v and acceleration a as
In dynamics Newton's laws predict the acceleration for a given force. Knowing the acceleration, and the kynematical relations defines above, you can solve for the position as a function of time: r(t)
Answer:
t = 2.13 s
Explanation:
given,
height of the building = 22.3 m
horizontal distance = 127 m
acceleration due to gravity = 9.8 m/s²
time for which ball is in motion = ?
using equation of motion
initial velocity is zero
t = √4.551
t = 2.13 s
Answer:
diameter = 9.951 × m
Explanation:
given data
NA = 0.1
refractive index = 1.465
wavelength = 1.3 μm
to find out
What is the largest core diameter for which the fiber remains single-mode
solution
we know that for single mode v number is
V ≤ 2.405
and v =
here r is radius
so we can say
= 2.405
put here value
= 2.405
solve it we get r
r = 4.975979 × m
so diameter is = 2 × 4.975979 × m
diameter = 9.951 × m
