A ________ is a geographical area with a base transceiver station at its center.

Atomic mass can be changed by the nuclear reactions which are nuclear fission and nuclear fusion.

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Answer:

The answer is m = 13.33Kg

Step by Step Explanation:

1- Taking into account Newton's second law (also known as the fundamental law of dynamics) we know that force is directly proportional to the mass and acceleration of a body.

2- This law is represented by the formula f = m.a where (f) represents force, (m) mass and (a) acceleration.

3- Having this formula, we can clear the mass (m) and replace the data given in the problem.

f = m.a

[tex]m = \frac{f}{a} \\m = \frac{20N}{1.5m/s^{2} } \\m = 13.33 kg[/tex]

Final answer:

Monatomic gold refers to individual gold atoms, while colloidal gold includes particles between 1 nanometer and 1 micrometer dispersed in a medium, displaying unique properties such as long-term stability and distinctive colors due to light absorption and scattering.

Explanation:

The difference between monatomic gold (Au) and colloidal gold lies in the size and dispersion of the gold particles. Monatomic gold refers to gold atoms that are not bonded to any other atoms, essentially in an isolated form. In contrast, colloidal gold consists of gold particles that are of colloidal size, meaning they range between 1 nanometer to 1 micrometer in diameter, and are dispersed in another substance, such as water. Colloidal particles are in a kind of “no person's land” between true solutions and solid particles, often not settling under gravity and can exhibit interesting properties such as the characteristic wine-red color of colloidal gold solutions due to selective absorption and scattering of light.

Colloidal gold is highly stable and can remain intact for many years, as illustrated by gold sols created in 1857 that are still intact. The state of dispersion and the color of colloidal gold can change with varying conditions such as particle size or environmental factors. On the other hand, monatomic atoms do not have such collective properties. Colloidal gold plays a significant role in various applications including medical diagnostics, due to its unique optical and chemical characteristics.

Final answer:

The current through the secondary coil of the given ideal transformer is calculated to be 3281.7 milliamps using the transformer equations and the provided values of primary voltage, turns ratio, and load resistance.

Explanation:

To calculate the current through the secondary coil of an ideal transformer, we need to use the transformer equations:

The voltage transformation ratio is given by:

V

p

/ V

s

= N

p

/ N

s

Where Vp is the primary voltage, Vs is the secondary voltage, Np is the number of turns in the primary coil, and Ns is the number of turns in the secondary coil. Given that the transformer is ideal, the power on both sides is equal, therefore:

P = V

p

× I

p

= V

s

× I

s

To find the secondary current (Is), we rearrange the power equation to solve for Is:

I

s

= P / V

s

Using Ohm's law (V = IR), we can find the secondary voltage (Vs) which is the voltage across the load resistance (R):

V

s

= I

s

× R

Combining the two sets of equations, we have:

V

p

/ (I

s

× R) = N

p

/ N

s

The primary voltage (Vp) is given as 36 volts, the primary turns (Np) are 86, the secondary turns (Ns) are 85, and the load resistance (R) is 19 ohms.

Solving for Is, we get:

I

s

= (N

s

/ N

p

) × (V

p

/ R)

Is = (85 / 86) × (36 V / 19 Ω)

Is = 1.732 × 1.895

Is = 3.2817 A

Since the question asks for the answer in milliamps:

Is = 3281.7 mA

The current through the secondary coil is thus 3281.7 milliamps.

A spreadsheet is software that is essential for performing a variety of tasks involving the organization and manipulation of data. It consists of multiple rows and columns that together create a grid, where data is stored and calculations can be made.

Each box, known as a cell, can hold individual pieces of data including text, numbers, and formulas. For instance, in Microsoft® Excel, a highly popular spreadsheet application, columns are identified with letters and rows with numbers. A cell at the intersection of column B and row 3 would be labeled as B3. Spreadsheets are widely used across different fields for data analysis, mathematical calculations, and information management.

When it comes to matrix algebra, spreadsheets also provide functionality to handle matrices, which are arrays of numbers arranged in rows and columns. The operations performed on matrices in a spreadsheet can range from basic arithmetic to more complex functions such as matrix multiplication or inversion.

Moreover, spreadsheets allow users to create charts, a visual representation of their data, making it easier to spot trends and patterns. Overall, spreadsheets are versatile tools that serve as an indispensable asset in both educational and professional settings.

An example of radiation is that a rock is warmed by an ultraviolet heat lamp. Thus, the correct option is B.

Radiation may be defined as the process of emission of energy in form of waves that originated from a source and travels through space at the speed of light.

Radiation actually occurs in close association with the waves of atmospheric air.

An ice pack that is placed on a knee, Hot coffee in a mug, and Cold salt water sinks do not provide any space for the entrance of atmospheric air.

Therefore, an example of radiation is that a rock is warmed by an ultraviolet heat lamp. Thus, the correct option is B.

Answer:

300 would be the best anwer.

Explanation:

Final answer:

The correct answer is that as the temperature of a blackbody radiator increases, the maximum intensity of radiation increases, and the peak wavelength decreases, resulting in a shift towards shorter wavelengths and more intense radiation.

Explanation:

The correct statement regarding how blackbody radiation changes as the temperature of the radiating object increases is that the maximum intensity increases, and the peak wavelength decreases. The distribution curves of blackbody radiation indicate that with higher temperatures, the intensity of radiation becomes greater, and the peak of the curve shifts toward shorter wavelengths. Objects such as lava become visible to the human eye at high enough temperatures, emitting radiation that progresses through colors red, orange, yellow, and eventually white as temperature increases - each color representing a decrease in wavelength and an increase in intensity.

When oxygen is not available, glycolysis produces lactate as its byproduct.Option A is correct.

A process through which cells partially break down glucose via oxygen-free enzyme activities. One process that cells employ to make energy is glycolysis.

The breakdown of glucose can occur more completely and more energy can be created when glycolysis is combined with other enzyme activities that require oxygen.

Pyruvate, the last result of glycolysis, is fermented to produce lactic acid, ethanol, and CO₂ in the absence of oxygen. Anaerobic respiration is the term for it.

Lactate is the end product of glycolysis when oxygen is not present.

Hence, option A is correct.
