The velocity of the wave on the string is given by

Solving the above equation,

The frequency of the wave
and wave length is 
The velocity is 
Substituting numerical values,

The length of the string is 
The correct answer for the question that is being presented above is this one: "B. color." The spectrum produced by a prism or a raindrop is evidence that the average speed of light in the material depends on the light's color. White light is being refracted into different colors.
Ride in a car down the street: constant velocity,
come to a red light: negative acceleration,
wait for the green light: zero velocity,
<span>start off again: </span>positive acceleration
<h3><u>Answer</u>;</h3>
D: 350 N forward
<h3><u>Explanation</u>;</h3>
The Resultant force is defined as the total force acting on a body along with their directions. When the object is at rest or travelling with the same velocity, the resultant force has to be zero.
Force is a vector quantity with both magnitude and direction.
Therefore, the resultant force will be the sum of the forces acting on the table;
Net Force = 200 N + 150 N (since they are acting in the same direction, forward)
<u>= 350 Newtons forward</u>
