Terminal Rating(110-14(C)(1):What size conductor is required to supply a 190 ampere load in a dry location? Terminals are rated 75 degrees C.

A wave's frequency varies when it moves from one medium to another. This is due to the fact that a wave's wavelength doesn't change when it enters a different medium, but its speed does. This is referred to as the frequency-wavelength relationship of the wave.

Based on the information provided in the table, the waves can be ranked from lowest energy to highest energy as follows: wave 1, wave 2, wave 3, and wave 4.

This is because wave energy is directly proportional to its amplitude and frequency, and in this case, the amplitude of wave 1 is the lowest, followed by wave 2, wave 3, and wave 4.
When a wave travels from one medium to another, its frequency changes.

This is because the speed of the wave changes when it enters a different medium, while its wavelength remains constant. This is known as the wave's frequency-wavelength relationship.

When the wave enters a denser medium, its speed decreases, and its frequency decreases as well. On the other hand, when the wave enters a less dense medium, its speed increases, and its frequency increases as well. Therefore, the change in media can affect the frequency of the wave.

Both grounded and ungrounded conductors of a two-wire circuit are considered current carrying. True. In a two-wire circuit, the grounded conductor is typically the neutral wire, which serves as a return path for the current.

The ungrounded conductor, usually the "hot" wire, supplies current to the load. Both conductors carry current, making this statement true. Grounding provides a path for fault current to flow back to the source, while bonding connects metal parts that could become energized to ensure they remain at the same potential. Under normal conditions, these conductors do not carry current. However, they are designed to carry fault current in the case of an electrical fault, which helps prevent dangerous voltage levels on surfaces and equipment. In order to assure safety and avoid electrical risks, electrical conductors must adhere to the National Electrical Code (NEC), whether they are carrying current or not.

Answer:

i feel its is america

Explanation:

A large force can produce a small torque when the force is applied perpendicular to the point of rotation, resulting in a shorter lever arm.

Conversely, a small force can produce a large torque when it is applied perpendicular to the point of rotation but at a greater distance from the pivot point, resulting in a longer lever arm. The torque produced by a force is calculated by multiplying the force by the distance from the pivot point, or lever arm. Thus, the amount produced depends on both the magnitude of the force and the distance from the pivot point. When a large force is applied perpendicular to the pivot point but at a short distance, the resulting torque is relatively small. Similarly, when a small force is applied perpendicular to the pivot point but at a greater distance, the result can be relatively large.

To calculate the hours a bird can fly using the energy supplied by 4.00 grams of fat, we need to find the total energy content of the fat and then divide it by the bird's energy consumption rate.

Fat provides approximately 9 kcal of energy per gram. First, convert the energy content of the fat to watts:

4.00 grams of fat * 9 kcal/gram = 36 kcal

1 kcal = 4184 joules

36 kcal * 4184 joules/kcal = 150,624 joules

1 watt = 1 joule/second, so the bird consumes 3.70 joules per second.

Now, divide the total energy content of the fat by the bird's energy consumption rate:

150,624 joules / 3.70 joules/second = 40,704 seconds

Finally, convert the seconds to hours:

40,704 seconds / 3600 seconds/hour ≈ 11.31 hours

So, the bird can fly for approximately 11.31 hours using the energy supplied by 4.00 grams of fat.

https://brainly.com/question/3551742

#SPJ11

The first step is to calculate the energy that can be obtained from 4.00 grams of fat.

One gram of fat can provide approximately 9 calories of energy, which is equivalent to 37.656 joules. Therefore, 4.00 grams of fat can provide:

Energy = 4.00 grams x 9 calories/gram x 4.184 joules/calorie

Energy = 150.336 joules

Next, we can calculate the time that the bird can fly using this energy supply by using the formula:

Time = Energy / Power

where Power is the rate at which the bird consumes energy, which is 3.70 watts.

Time = 150.336 joules / 3.70 watts

Time = 40.62 seconds

Therefore, the bird can fly for approximately 40.62 seconds using the energy supply provided by 4.00 grams of fat.

The expected runtime with ten cores is 55.2 seconds.

To calculate the expected runtime with ten cores, we need to consider the fixed overhead and the parallel runtime.
First, we need to calculate the total overhead for the six-core parallel runtime. If the parallel runtime is 12s, we can assume that the fixed overhead is included in this time. Therefore, we can calculate the total overhead as follows:
Total overhead = Parallel runtime - Serial runtime
Total overhead = 12s - 60s
Total overhead = -48s
Note that the total overhead is negative, which means that the parallel runtime is faster than the serial runtime even when accounting for the fixed overhead.
Next, we can use the total overhead to calculate the expected runtime for ten cores. Assuming that the overhead remains constant regardless of the number of cores used, we can use the following equation:
Expected runtime = Serial runtime + (Parallel runtime - Serial runtime) / Number of cores
Plugging in the values we have:
Expected runtime = 60s + (-48s) / 10
Expected runtime = 60s - 4.8s
Expected runtime = 55.2s
Therefore, the expected runtime with ten cores is 55.2 seconds.

To convert 687 torr to atmospheres (atm), you can use the given relationship:

1 atm = 760 torr.

To find the value in atmospheres, simply divide the pressure in torr by the conversion factor:

687 torr ÷ 760 torr/atm ≈ 0.904 atm

So, a pressure of 687 torr is approximately equal to 0.904 atmospheres.

To explain this, we can say that one atmosphere (atm) of pressure is defined as the pressure exerted by the weight of the earth's atmosphere at sea level. Torr is another unit of pressure, named after the Italian physicist Evangelista Torricelli. It is defined as the pressure exerted by a column of mercury 1 millimeter high at 0 °C.

Since 760 torr is equal to one atmosphere of pressure, we can use this conversion factor to convert between the two units. In this case, we are given a pressure of 687 torr, and we use the conversion factor of 760 torr/atm to convert it to atmospheres.

A string, 0.26 m long and vibrating in its sixth harmonic, excites an open pipe that is 1.16 m long into its second overtone resonance. the speed of sound in air is 345 m/s. 78.3 m/s is the speed of transverse waves on the string.

To solve this problem, we need to use the formula v = fλ, where v is the speed of the wave, f is the frequency, and λ is the wavelength.
First, we need to find the frequency of the string. Since it is vibrating in its sixth harmonic, we know that there are six antinodes (or nodes) along the string. The wavelength of the wave on the string is twice the length of the string, so:
λ = 2(0.26 m) = 0.52 m
The sixth harmonic means that there are six half-wavelengths along the string, so the frequency is:
f = 6v/λ
where v is the speed of the wave on the string. We want to solve for v, so we can rearrange the formula to:
v = fλ/6
Next, we need to find the frequency of the pipe. It is in its second overtone resonance, which means that it has two antinodes (or nodes) and three segments (or half-wavelengths). The wavelength of the wave in the pipe is:
λ = 2(1.16 m)/3 = 0.77 m
The frequency of the pipe is:
f = 2v/λ
where v is the speed of sound in air. We know that v = 345 m/s, so we can substitute that in and solve for f:
f = 2(345 m/s)/0.77 m = 894.8 Hz
Now we can use the formula v = fλ/6 to find the speed of the wave on the string:
v = (894.8 Hz)(0.52 m)/6 = 78.3 m/s
So the speed of transverse waves on the string is 78.3 m/s.

a. To calculate the total asset turnover, you need to divide the sales by the total assets. In this case, the sales are given as $14.2 million and the total assets are $6.75 million.

Total asset turnover = Sales / Total assets

Substituting the given values, we have:

Total asset turnover = $14.2 million / $6.75 million

To calculate this, divide 14.2 by 6.75: 14.2 / 6.75 = 2.1037

Round your answer to 2 decimal places to get a total asset turnover of 2.10.

b. Now, let's calculate the new sales figure required to achieve a total asset turnover of 2.75 times. Assuming there is no increase in total assets, we can set up the following equation:

New sales / $6.75 million = 2.75

To find the new sales figure, we need to multiply the total assets by the desired total asset turnover:

New sales = $6.75 million * 2.75

Multiply 6.75 by 2.75: 6.75 * 2.75 = 18.5625

Since the answer needs to be rounded to the nearest whole number, the new sales figure would be approximately $18.56 million.

Answer:  The reason why some objects feel warmer than others even if they are at the same temperature has to do with their thermal conductivity. Thermal conductivity is a measure of how well a material can transfer heat. Materials with high thermal conductivity transfer heat easily, while materials with low thermal conductivity do not transfer heat as easily.

When you touch an object, your skin can’t actually detect the temperature of the object itself. Instead, it senses its own temperature. If you touch an object that is a good thermal conductor, it will transfer heat to or from your skin quickly, making your skin feel warmer or colder. On the other hand, if you touch an object that is not a good thermal conductor, it will transfer heat to or from your skin more slowly, so your skin won’t feel as warm or cold.

So, even if two objects are at the same temperature, one may feel warmer than the other because it is transferring heat to your skin more quickly due to its higher thermal conductivity.
