Answer:

Explanation:
the Frequency of string is given by

T= tension in the string
μ= mass per unit length of string
l= length of string
in the given question
= 4
here subscript 1 is massive string and subscript 2 is lighter string

and

dividing f_1 by f_2 we get
now 
= 
= 
⇒ 
hence the fundamental frequency of massive string is half of the fundamental frequency of lighter string

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

where
is the speed of the rain, which travels vertically
is the speed of the bus, which travels horizontally
Substituting, we find

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.
