For a standing wave if both ends are fixed, the wavelength must be such that the length of the string be an exact multiple of a half wavelength.
The longest wavelength must be such that the length of the string must be equal to half a wavelength, and therefore the wavelength must be double the length of the string; That is 240× 2 = 480 cm
The second longest wavelength must be such that the length of the string must be equal to a whole wavelength, so the second longest wavelength must be 240 cm.
The third longest wavelength must be such that the length of the string must be equal to 1.5 times the wavelength, so the wavelength must be 240/1.5 = 160 cm.

Explanation:
From the FBD in the attachment we can write that
N+ 80 sin37°= mg
N= 46×g-80×sin37=498.94 N
also, ma= 80×cos37°
a= 80×cos37°/46= 1.3889 m/s^2
also, 10m = 0.5at^2
put a= 1.3889 m/s^2
t= 2.095 secs
d) the speed v =at
v= 1.3889*2.095= 2.91 m/s^2
Answer:
If your mass on Earth is 71 Kg, what is your weight on Earth to two decimal places?
your mother you uncultured swain how dumb can you be go jump off a bridge ETAY who even names there child ETAY more like EBAY
Um, since I'm unsure what your question is, I think you're referring to the Periodic Table, which in that case, it's #6. ;-)
Answer: D
Explanation: The kinetic energy would become Zero.
According to conservative of energy, the total energy is equal to maximum K.E plus maximum P.E.
As the object comes to rest the potential energy will be maximum, and Kinetic energy becomes zero.
