Via the half-life equation:
Where the time elapse is 11,460 year and the half-life is 5,730 years.
Therefore after 11,460 years the amount of carbon-14 is one fourth (1/4) of the original amount.
Answer:
a). 87.5 mA or A
b). 1.78
Explanation:
n the number of free electrons is 28 in text reference and if they don't give q is take as the charge of electron.
a).
A
b).
Answer:
PART A
In a solid
The attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.
In a liquid
Particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
A gas
The particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.
PART B
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.

GOOD LUCK!!! :)
Current can vary in different branches of a circuit
Answer:
the reaction mechanism occurs by electrostatic attraction of some type, where electrons are shared or transferred into the atoms and the new molecular compound is established more betabel than the indigenous atoms
Explanation:
Molecules are formed by atoms, through those of many chemical reactions that are processes by which the energy of the products is less than the energy of the reactants.
In these processes, in general, the reaction mechanism occurs by electrostatic attraction of some type, where electrons are shared or transferred into the atoms and the new molecular compound is established more betabel than the indigenous atoms
