Answer:
![R_{max} = 14 m](https://tex.z-dn.net/?f=R_%7Bmax%7D%20%3D%2014%20m)
Explanation:
Maximum height reached by Dolphins is given as
![H = 7 m](https://tex.z-dn.net/?f=H%20%3D%207%20m)
now we know that
![H = \frac{v^2}{2g}](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7Bv%5E2%7D%7B2g%7D)
![7 = \frac{v^2}{2g}](https://tex.z-dn.net/?f=7%20%3D%20%5Cfrac%7Bv%5E2%7D%7B2g%7D)
![v^2 = 2(7)(9.81)](https://tex.z-dn.net/?f=v%5E2%20%3D%202%287%29%289.81%29)
![v = 11.72 m/s](https://tex.z-dn.net/?f=v%20%3D%2011.72%20m%2Fs)
now the formula of range is given as
![R = \frac{v^2 sin(2\theta)}{g}](https://tex.z-dn.net/?f=R%20%3D%20%5Cfrac%7Bv%5E2%20sin%282%5Ctheta%29%7D%7Bg%7D)
now we know that for maximum range the angle should be 45 degree
so we will have
![R_{max} = \frac{v^2}{g}](https://tex.z-dn.net/?f=R_%7Bmax%7D%20%3D%20%5Cfrac%7Bv%5E2%7D%7Bg%7D)
![R_{max} = 7 \times 2](https://tex.z-dn.net/?f=R_%7Bmax%7D%20%3D%207%20%5Ctimes%202)
![R_{max} = 14 m](https://tex.z-dn.net/?f=R_%7Bmax%7D%20%3D%2014%20m)
The height is zero.
That means whatever place is your reference for height measurement,
the object is lying right there at that height.
A common activity like cooking a meal can use many natural <u>Ingredients </u>
<h3>Ingredients </h3>
Ingredients are substances combined to make a particular mixture such as a meal. most of the ingredients used for the preparation of a meal are sourced naturally.
In cooking different recipes of a meal the use of specific ingredients for each recipe differentiates the recipes.
