Question
I hope you help me with all these question.
I don't need explanation,
just give me true or false answer!!Thankyou!
Street City state Code For each of the following statements, circle T if the statement is true and circle F if the statement is false TF Simple harmonic motion can be represented by a sine curve. 2 TF A violin string that vibrates with a frequency of 196 Hz produces a sound wave 3. T F A pendulum with a mass of 10 g and a length of 20 cm swings back and forth with a frequency of 1/196 Hz. more frequently than a pendulum with a mass of 20 g and a length of 10 cm. than the wavelength produced by a piano string with a frequency of 262 Hz. 4 TFThe wavelength produced by a violin string with a frequency of 196 Hz is greater . TF When a transverse wave moves in a medium, the motion of the medium is in the same direction as the motion of the wave. 6.TFWhen the crests of two waves overlap. the result is destructive interference 7. TF All elastic materials have a natural frequency 8. TFAccelerating clectric charges produce longitudinal waves. 9. TFIn a vacuum, blue light moves at a faster speed than red light 10. TFBlue light has a higher frequency than red light. Answer the following questions by writing on the blank lines the letterts) of the word or phrase that best complete(s) the statement or answers the question. Choose only one answer unless a ve, but
Explanation / Answer
1) True, x= A sin wt
2)False, it will be 196 Hz
3)False, frequency decreases with increase in length
4)True, wavelength decreases if Frequency increases
5)False, it's perpendicular
6)False, its constructive.
7)True, all have a natural Frequency
8)True, it produces electromagnetic wave which is longitudinal
9)False, all have same speed in vacuum
10)False, all have same frequency.
