A periodic wave (i. e., a wave pattern that repeats itself) is produced in a stretched string by a mechanical oscillator operating at a frequency of 465 Hz. This means that one point on the stretched string is pushed up and down at a regular frequency. The so-called "oscillator" is the source of the repeating waves. The linear density of the string is 0.00140 kg/m and the wavelength of the periodic wave is 0.0700 m.

For me a person with a phd and who knows what there talking about.i know the chances of a radiation leak is low but if it does the area within a 96.3 mile radius would be unusable because of contamination

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
