Answer:
continually change by the same amount each second
Explanation:
We all are aware with the fact that a car speeds is increased when we put our feet on the accelerator. The rate at which the particle's velocity change with time is called its acceleration. If the particle's velocity changes with constant rate, then its rate is called the constant acceleration.
Since the basic units are meter and seconds. And the SI unit of velocity is and acceleration's SI unit is
For example if the velocity is change from 2 to 4 m/s in 1 sec its acceleration is and again its velocity is change with 4 m/s to 6 m/s will again give constant acceleration in 1 s is

Answer:
A) 1.122 m
B) 5.4 hertz
C) 6.06 m/s ( towards negative x axis )
D) 0.22
E) max speed = amplitude * 34
= 0.22 * 34 = 7.48
minimum speed ( speed at rest ) = 0
Explanation:
The travelling wave = D = 0.22sin ( 5.6x + 34t)
this wave is represented in the form : D = Asin ( kx + wt)
A) wavelength
k = 2 / v
v = wavelength
k = 5.6
therefore wavelength ( v ) from the equation = 2 / 5.6 = 1.122 m
B ) frequency
w = 2f
w = 34
f = frequency
therefore f = w / 2 = 34 / 2
= 5.4 hertz
C ) velocity
speed = f v
v = 5.4 * 1.122 = 6.06 m/s ( towards negative x axis )
D) amplitude
A = 0.22
E ) maximum and minimum speeds of particles on the chord
max speed = amplitude * 34
= 0.22 * 34 = 7.48
minimum speed ( speed at rest ) = 0
