How long is a string under 240 N of tension whose mass is 0.086 kg if a wave travels through it at a speed of 12 m/s?

Darina [25.2K]

Answer:

The length of the string is 0.051 meters

Explanation:

It is given that,

Tension in the string, T = 240 N

Mass of the string, m = 0.086 kg

Speed of the wave, v = 12 m/s

The speed of the wave on the string is given by :

$v=\sqrt{\dfrac{T}{M}}$

M is the mass per unit length of the string i.e. M = m/l.......(1)

So, $M=\dfrac{T}{v^2}$

$M=\dfrac{240\ N}{(12\ m/s)^2}$

M = 1.67 kg/m

The length of the string can be calculated using equation (1) :

$l=\dfrac{m}{M}$

$l=\dfrac{0.086\ kg}{1.67\ kg/m}$

l = 0.051 m

So, the length of the string is 0.051 meters. Hence, this is the required solution.

Technician A says that the HVAC doors in an automatic system are vacuum-operated. Technician B says that the HVAC doors in an au

Gala2k [10]

Option C

Both technicians are correct

<h3><u>Explanation:</u></h3>

HVAC persists for Heating Ventilation and Air Conditioning. Its design in a vehicle is to cleanse, cool, flame, control, and dehumidify the air accessing the cabin, depending on the inputs of the operator as thoroughly as electronic sensors. Various systems will practice diverse ways of regulating airflow into the cabin but all act on identical basic principles.

The automatic systems are electric systems that want different inputs from sensors that intimate climate circumstances to obtain the aspired temperature. Vacuum actuators and/or electric motors control the air doors/valves in these systems.
