A student is carrying out an investigation in which a string of known length is plucked and then the student measures the resulting frequency of vibration in the string to determine the speed of the waves. If the student increases the tension in the string, how will it affect the frequency and speed of the waves in the string? (DOK 3)
Question 15 options:
A. The speed will increase and the frequency will remain the same because the properties of the medium has changed but the wavelength will be the same.
B. Both the frequency and speed will increase because the properties of the medium have changed and the wavelength stays the same.
C. The frequency will increase but the speed will remain the same because the medium is the same but the wavelength is smaller.
D. Neither the frequency nor the speed will change because the medium is the same.

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
