A force of 2.20 N is exerted on a 7,20 g rifle bullet. What is the bullet's acceleration? (Enter your answer in m/s^ 2 )
sweet [91]

Answer:

The answer is 306 m/s^2

Explanation:

F = m*a

We can rearrange this formula to get a = F / m.

The SI unit for mass is kilograms (kg).

The SI unit for acceleration is m/s^2.

There are 1000 grams in a kilogram.

7.20 g = 0.00720 kg

Force (2.20 N) / 0.00720 kg = 305.56 m/s^2

Accounting for Sig Figs, the answer is 306 m/s^2.

Gee, that's one fast bullet.

Cellular respiration and fermentation both. . A. begin with the breakdown of glucose in glycolysis. . B.produce the same number
Rus_ich [418]

The correct answer is:

A. begin with the breakdown of glucose in glycolysis.

Explanation:

They both begin with a sequence of reactions known as glycolysis, which breaks glucose particles into smaller pyruvate molecules. They are also related in that through both processes, ATP is generated for the cell to use. Glycolysis is the metabolic pathway that transforms glucose C6H12O6, into pyruvate, CH3COCOO− + H+. The free energy delivered in this process is applied to form the high-energy molecules ATP and NADH .
