una cuerda de 200 cm de longitud tiene una masa de 500g cual es la tensión de la cuerda que se requiere para producir una velocidad de onda de 120 cm/s

T = 0.36 N

Explanation:

Given that,

Length of a rope, l = 200 cm = 2 m

Mass, m = 500 g = 0.5 kg

It would produce a wave speed of 120 cm/s or 1.2 m/s

We need to find the tension of the rope. The speed of a wave in the stretched string is given by :

Where T is tension of the rope and is the mass per unit length

So, the tension of the rope is 0.36 N.

an obstruction

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
