Q1. A steel wire with mass 25.43 g and length 1.33 m is strung on a bass so that the distance from the nut to the bridge is 1.13 m
(a) calculate the linear density of the string.
(b) What velocity wave on the string would produce the desired fundamental frequency of the E1 string, 35.65 Hz?
(c) Calculate the tension required to obtain the proper frequency.
(d) Calculate the wavelength of string's vibration.
(e) What is the wavelength of the sound produced in air? (Presume the speed of sound in air is 343 m/s.)
Q2. A ferrari race car on the straight road starts from rest, accelerating at 2.00 m/s^2 until it reaches a speed of 20.0m/s. Then the car travels for 20.0 s at the constant speed until the brakes are applied, stopping the truck in a uniform manner in an added 5.00 s. (a) how long is the truck in motion? (b)What is the average velocity of the truck for motion described?
Each is afraid that one vine will break; as a result they grab each other and hang on. They swing upward together, reaching a point where the vines make an angle of 22.1° with the vertical. Find the value of the ratio m/M.

Before starting this problem, review Conceptual. The force vector A has the magnitude of 75.0 newtons (N) and points due east. The force vector B has a magnitude of 101 N and points 72.9 ° north of east.
Find out the magnitude of the charge on the moving particle. The baby soon learns to bounce with utmost amplitude and minimum effort by bending her knees at what frequency.
What is the maximum displacement of the bridge deck?
The alpha line in the Balmer series of the hydrogen spectrum consists of light having a wavelength of 6.56 ×10-7 meter. Compute the frequency of this light.
Light of wavelength 588 nm falls on a double slit. First-order bright bands appear 3.65 cm from the central bright band. The screen is 1.20 m from the slits. How far apart are the slits.
