In music, the note G above middle C has a frequency of about 392 hertz. If the speed of sound in the air is 340 m/s, what is the approximate wavelength of this note?(1 point) 0.87 meters

0.0026 meters

1.2 meters

8.7 meters

(cmmt if you wanna be added to a physics B ig gc)

1.2 meter because the equa

1.) 2 seconds

2.) 4.5 hertz

3.) it will become one third its original value

4.) 5.9 seconds

5.) 0.87 meters

Explanation:

just took the connexus quick check

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
