Answer:
you add 67 to 1+1 is this clear also chicken nuggets
Transverse wave = at right angles to the direction of the motion of the wave
in transverse wave medium particles will move perpendicular to the direction of motion of medium particles
they all are perpendicular to wave always
Longitudinal wave = back and forth in the direction of the motion of the wave
in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type
electromagnetic wave = alternating waves moving at right angles to each other
electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other
The net force needed to lift a full grocery sack uniformly is 32.115 N.
<h3>What is Net force?</h3>
When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.
Given the weight of sack W = 210N and the acceleration a = 1.5m/s².
The mass of the sack will be
m = Weight / acceleration due to gravity
m = 210 N/9.81 m/s²
m = 21.41 kg
Using Newton's second law, the net force will be
F = mass x acceleration
F= 21.41 x 1.5
F = 32.115 N
Thus, the net force is 32.115 N.
