9.6x10^85/3x10^63 in scientific notation

Novosadov [1.4K]

Answer:

Step-by-step explanation:

Given the expression 9.6x10^85/3x10^63, we are to write it on scientific notation as shown:

9.6x10^85/3x10^63

= (9.8/3) * (10^85/10^63)

= (9.8/3) * 10^{85-63}

= (9.8/3) *10^22

= 3.27 *10^22

<em>Hence the expression in scientific notation is 3.27*10^22</em>

If an object takes 7 second to fall to the ground, what was its initial height? Show your work.

Verdich [7]

Answer:240.1 m

Step-by-step explanation:

We are given the following equation that models the the time it takes to an object to fall to the ground:

$t_{(H)}=\sqrt{\frac{2H}{g}}$

Where:

$t_{(H)}=7 s$ is the time it takes to the object to fall to the ground

$H$ is the object's initial height

$g=9.8 m/s^{2}$ is the acceleration due gravity

Isolating $H$ :

$t^{2}=(\sqrt{\frac{2H}{g}})^{2}$

$t^{2}=\frac{2H}{g}}$

$H=\frac{t^{2}g}{2}$

Solving with the given data:

$H=\frac{(7 s)^{2}(9.8 m/s^{2})}{2}$

$H=240.1 m$ This is the initial height
