D) 12 sodium, 4 phosphorus, 16 oxygen
sodium: 4Na3 -> 4 • 3 = 12
phosphorus: 4P - > 4
oxygen 4O4 -> 4 • 4 = 16
(the four is from the four in front of the whole formula)

Both masses will have the same acceleration. The cart accelerates to the right with a magnitude of 4.9 m/. The correct answer is 4.90 m/
Given that a massless string connects a 1.00 kg mass to a 3.00 kg cart which is resting on a frictionless horizontal surface.
Let M = 1kg and m = 3 kg
Since the horizontal surface is frictionless, the tension in the string will be the same. when the mass is hanged over a frictionless pulley, the tension will also be the same.
When the mass is released, the cart accelerates to the right can be calculated from Newton' second law of motion. That is,
M( g + a) = m(g - a)
1(9.8 + a) = 3( 9.8 - a)
9.8 +a = 29.4 - 3a
collect the like terms
4a = 19.6
a = 19.6/4
a = 4.9 m/
Therefore, the cart accelerates to the right with a magnitude of 4.9 m/. The correct answer is 4.90 m/

These group of cells that perform the same function is called a tissue. Both animal and plant cells can form tissue. An example is bone tissue in animals. A living tissue is composed of a group of cells with a similar structure and function, which all perform together a specific task or job.
Examples of tissues include:
1. Lining of the lungs
2. Lining of the intestines
3. muscle
4. Xylem in plants.
A group of different tissues performing the same task make up an organ.
