<span>There is an equal number of electrons and protrons. Therefore, the positive & negative charges cancel out. That gives the atom no electric charge.</span>

An equal number. Electrons have a negative charge, protons positive. An equal number of positive and negative cancel each other out, hence neutral.

What is the total capacitance in units of mF, of the two capacitors connected in series, as shown in the diagram, when C1 = 45 m
elena-14-01-66 [18.8K]

Answer:

16.7 mF

Explanation:

The total capacitance of two capacitors connected in series is given by the formula:

\frac{1}{C}=\frac{1}{C_1}+\frac{1}{C_2}

in our problem, we have:

C1 = 45 mF is the capacitance of the first capacitor

C2 = 26 mF is the capacitance of the second capacitor

Substituting into the equation, we find:

\frac{1}{C}=\frac{1}{45 mF}+\frac{1}{26 mF}=0.06 mF^{-1}\\C=\frac{1}{0.06 mF^{-1}}=16.7 mF

IRISSAK [1]

Answer:

By decreasing the surface area exposed to the air. Vertical body position instead of horizontal.

Explanation:

So the terminal velocity formula is as follows.

v = sqrt[(2*m*g)/(p*A*c)]

m = mass

g = 9.81 m/s^2

p = density of air

A = surface area of object

c = Drag coefficient

So the only thing you can change in mid-air is surface area.

The temperature of a quantity of an ideal gas is a. one measure of its ability to transfer thermal energy to another body. b. pr
solong [7]

Answer:

d. correctly described by all the statements above.

Explanation:

Kinetic molecular theory of gases states that gas particles exhibit a perfectly elastic collision and are constantly in motion.

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on temperature.

This ultimately implies that, the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas. Thus, an increase in the average kinetic energy of gas particles would cause an increase in the absolute temperature of an ideal gas.

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Generally, the temperature of a quantity of an ideal gas is;

a. a measure of the ability of an ideal gas to transfer thermal energy to another body.

b. the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas

c. proportional to the internal energy of the gas.
