Answer:
Velocity = v = 35 m/s
Explanation:
Kinetic energy of an object is defined as the energy possess by an object due to its motion. Kinetic energy K.E of an object is equal to the half of the mass of that object multiplied by square of the object's velocity.
Mathematically,
v = 35 m/s
Answer:
F = 5
Explanation:
F = m x v^2/r = 2 x 10^2/5 =200/5 = 40 (N)
Answer:
y = 0.010 cos ( 1539.4 t + 0.645)
Explanation:
The general equation for a wave on a string is
y = A sin (kx - wt)
Where k is the wave number
k = 2π /λ
k = 2π / 3 10⁻²
k = 209.4 m⁻¹
The angular velocity is related to the frequency
w = 2π f
w = 2π 245
w = 1539.4 rad / s
The maximum amplitude is
.A = 0.0100 m
The wave equation is
y = 0.01 sin (-209.4 x - 1539.4 t)
The particle that is at each point of this wave performs an oscillatory movement perpendicular to the wave discarded by
y = yo cos (wt + fi)
The angular velocity of the particle is equal to the velocity of the wave
w = 1539.4 rad / s
The breadth of displacement is
y₀ = 0.01 m
With the initial data let's look for the phase
0.008 = 0.01 cos (0+ Ф)
Ф = cos⁻¹ (0.008 / 0.01)
Ф = 0.645 rad
Therefore the equation is
y = 0.010 cos ( 1539.4 t + 0.645)
Answer:
Frequency of incident light = 995×10 12
Explanation:
hope this helped you :)
In longitudinal waves, the motion of the particles in a medium is across the direction of the wave.
