What is the tension on a string with a mass of 1.6 kg, with a length of
0.8 m, if the speed of the wave on the string is 2.5 m/s?

The tension in the rope is thus 8 N.

Explanation:

Given data:

mass = M = 1.6 kg

length = L = 0.8 m

speed of the wave = v = 2.5 m/s

To find:

Tension on a string =F = ?

Formula:

The speed of a wave on a string is determined by the tension through the formula

v =

Solving for the tension F, we find

F = v^2 M / L

F = (2.5 m/s)^2 x 1.6 kg x 0.8 m

F = 6.25 x 1.6 x 0.8

F =  8 N

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
