Two strings have the same length and tension. One string has a mass per length that is 4 times that of the other string. The fun
Anit [1.1K]

Answer:

f_1=\frac{f_2}{2}

Explanation:

the Frequency of string is given by

f= \frac{1}{2l}\times\sqrt{\frac{T}{\mu }}

T= tension in the string

μ= mass per unit length of string

l= length of string

in the given question \mu_{1}= 4\mu_{2}

here subscript 1 is massive string and subscript 2 is lighter string

f_{1}= \frac{1}{2l}\times\sqrt{\frac{T}{\mu_{1} }}

and

f_{2}= \frac{1}{2l}\times\sqrt{\frac{T}{\mu_{2} }}

dividing f_1  by f_2 we get

now \frac{f_{1}}{f_{2}} =\sqrt{\frac{\mu_2}{\mu_1} }

= \sqrt{\frac{\mu_2}{4\mu_2} }

= \frac{1}{2}

⇒ f_1=\frac{f_2}{2}

hence the fundamental frequency of massive string is half of the fundamental frequency of lighter string

A bus with a vertical wind shield moves horizontally
Katena32 [7]

Answer:

(3) 53°

Explanation:

We want to measure the angle that the rains form with the vertical wind shield, so we have to measure the angle relative to the vertical. This means that we can write the following equation

tan \theta = \frac{v_x}{v_y}

where

v_y = 30 km/h is the speed of the rain, which travels vertically

v_x = 40 km/h is the speed of the bus, which travels horizontally

Substituting, we find

\theta=tan^{-1}(\frac{40}{30})=53^{\circ}

Answer:

D. the distance and direction to the water fountain

Explanation:

To describe the position of a water fountain relative to where one is standing, the distance and direction to the water fountain must be known.

This quantity is known as the displacement.

  • Displacement is a vector quantity with both magnitude and direction.
  • To specify the magnitude of a displacement, we use the length of path and in this case the height or sometimes the distance.
  • The direction attribute distinguishes distance from displacement
  • The perfect quantity to solve this problem is the displacement and it specifies the distance of the path and the direction traveled.
