Answer:

29.4m/s

Explanation:

Given.

Time (t) = 3.0s

Required

Determine the final velocity

Since, it's a vertical motion, we make use of the following formula to solve for the final velocity (v).

v = u + gt

Where u = 0, g = 9.8m/s² and t = 3s

v = 0 + 9.8m/s² *3s

v = 0 + 29.4m/s

v = 29.4m/s

Hence, the final velocity is 29.4m/s

What’s 3 times 10 to the 8th power divided by 2.45 times 10 to the 9th power

0.12244898 is the value obtained when solving the given.

<u>Explanation:</u>

Given:

3 times 10 to the 8th power can be expressed in equation format as $3 \times 10^{8}$ (3 times symbolizes ‘multiplication’ then it is to the tenth power of 8)

2.45 times 10 to the 9th power can be expressed in equation format as $2.45 \times 10^{9}$ (2.45 times symbolizes ‘multiplication’, then it is to the tenth power of 9)

Asked to find the solution when dividing the above,

$\frac{3 \times 10^{8}}{2.45 \times 10^{9}}=\frac{3}{2.45} \times 10^{8-9}$

When the tenth power of any value goes from denominator to numerator and vice-versa, presents in opposite sign to that it possess (like when ‘ $10^{9}$ ' goes to numerator changed as ' $10^{-9}$ ').

Now by solving the above equation, we get

$\frac{3}{2.45} \times 10^{8-9}=1.22 \times 10^{-1}=\frac{1.22}{10}=0.12244898$

Ipatiy [6.2K]

Answer and Explanation: One ATP release approximately 30.5kJ/mol of energy. Using Avogadro's constant, it is known one mol corresponds to $6.02.10^{23}$ molecules, so 106 ATP molecules releases:
