A wire with mass 40 g is stretched so that it’s ends are tied down at points 80cm apart. The wire vibrates in its fundamental mode with frequency 60Hz and amplitude of 0.3 cm at antibodies. What is the speed of propagation of transverse waves in the wire?

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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
