these four trucks are identical each box loaded on the truck has the same mass choose the truck that has the greatest force of g
ravity acting on it

Answer:
Green truck.
Explanation:
The gravitational force acting on any object is given as:
where, f = force due to gravity
m = mass of the object
g = acceleration due to gravity.
In the given option the mas of each box is same. Also all the trucks are identical. So the force will be more for the truck which has more no. of boxes loaded on it.
The green truck has 6 boxes and other trucks have less boxes. This is why the greatest force of gravity will be acting on Green truck.

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
