The main reason for building large optical telescopes on the Earth's surface is to collect as much light as possible from faint objects.

Option B is the correct choice. Large optical telescopes are constructed on the Earth's surface primarily to maximize the collection of light from distant and faint celestial objects. By having a larger aperture, these telescopes can gather more photons, increasing the sensitivity and resolution of the observations.

The Earth's atmosphere also plays a significant role in the operation of optical telescopes. While it can introduce some challenges due to atmospheric turbulence, advancements in adaptive optics have helped mitigate these effects. The presence of an atmosphere also offers the advantage of filtering certain wavelengths, allowing astronomers to conduct observations in specific ranges of the electromagnetic spectrum.

Options A, C, and D are not accurate explanations for why large optical telescopes are built on the Earth's surface. The motivation behind constructing such telescopes is primarily driven by scientific goals and the desire to enhance our understanding of the universe through improved light collection capabilities

According to Kepler's first law of planetary motion, planets revolve around the sun such that the sun is always at one of its foci. This law is also known as the law of orbits.

According to Kepler's Second Law of planetary motion, a planet will cover equal amounts of area in an equal period of time if a line is drawn from the sun to the planet. This implies that the planet moves more slowly away from the sun and faster towards it.

According to Kepler's third Law of Planetary Motion, the squares of the orbital periods of the planets are directly proportional to the cubes of their semi-major axes.

The simple evaluation technique of VT is based on the idea that threshold voltage (VT) is equal to the gate voltage at which the inversion layer charge density is zero.

Explanation:

The simple evaluation technique of VT is based on the idea that threshold voltage (VT) is equal to the gate voltage at which the inversion layer charge density is zero. When measuring the threshold voltage of a PMOS device using the VTP method, a positive voltage is applied to the drain terminal and a negative voltage is applied to the source terminal. This causes the transistor to be turned off since the body is positively biased and the PMOS channel will not conduct current. A negative voltage is then applied to the gate, which is gradually increased.

The device is turned on when the threshold voltage is reached, and the inversion layer charge density is no longer zero. Therefore, the gate voltage at which the device is turned on is equal to the threshold voltage (VT). Thus, the VTP measurement technique for PMOS devices is based on the simple evaluation technique of VT, which is the gate voltage at which the inversion layer charge density is zero.

Explanation:

heating of anything increases the kinetic energy of its molecules, so the molecules will move faster.

A helium balloon's temperature is raised by 1°C. This will cause molecules to move faster.

The temperature has an impact on this average kinetic (motional) energy. Their average kinetic energy likewise rises when gas molecules warm up.

As a result, they travel more quickly and collide more frequently and violently inside the balloon. The temperature has an impact on the hot air balloon's internal pressure. The molecules move more quickly and forcefully against the interior wall of the balloon as they warm up.

A region of the balloon is subjected to more force due to the gas particles' greater velocity, which raises the pressure there.

Therefore, the temperature of a helium balloon is increased by 1°C. Molecules will move more quickly as a result.

The total distance covered by the hiker is 77 km.

To calculate the total distance covered by the hiker, we need to add up the distances of each individual walk.

For the first walk, the hiker covers a distance of 21 km at an angle of 143 degrees. The distance traveled can be calculated using the formula: distance = magnitude × cos(angle). Thus, the distance for the first walk is 21 km × cos(143°).

For the second walk, the hiker covers a distance of 24 km at an angle of 250 degrees. Using the same formula, the distance for the second walk is 24 km × cos(250°).

For the third walk, the hiker covers a distance of 16 km at an angle of 161 degrees. Again, applying the formula, the distance for the third walk is 16 km × cos(161°).

Finally, for the fourth walk, the hiker covers a distance of 16 km at an angle of 84 degrees. The distance can be calculated as 16 km × cos(84°).

To find the total distance, we add up the distances from each walk: (21 km × cos(143°)) + (24 km × cos(250°)) + (16 km × cos(161°)) + (16 km × cos(84°)) = 77 km.

Answer:

The volume of the ideal gas on another planet will be 6.7 m³.

Explanation:

We can find the volume occupied by the ideal gas on another planet by using the Ideal Gas Law:

\( PV = nRT \)

Where:

P: is the pressure

V: is the volume

n: is the number of moles

R: is the gas constant = 8.206x10⁻⁵ m³ atm K⁻¹mol⁻¹

T: is the temperature              

Since the gas occupies a volume of 8.7 m³ with a pressure of 6 atm and temperature 4.8 °C on earth, we have the following number of moles:

\( n = \frac{PV}{RT} = \frac{6 atm*8.7 m^{3}}{8.206 \cdot 10^{-5} m^{3}atm/(Kmol)*(4.8 + 273)K} = 2289.9 moles \)

Now we can calculate the volume occupied by the ideal gas on another planet:

\( V = \frac{nRT}{P} \)

With T = 8.7 °C and P = 7.9 atm

\( V = \frac{2289.9 moles*8.206 \cdot 10^{-5} m^{3}atm/(Kmol)*(8.7 + 273)K}{7.9 atm} = 6.7 m^{3} \)

Therefore, the volume of the ideal gas on another planet will be 6.7 m³.

Investigating the nature versus nurture theories of human personality development requires the use of a combination of different types of studies. By using a multidisciplinary approach, researchers can gain a better understanding of how both genetics and environmental factors contribute to personality development.

One type of study is behavioral genetics research, which examines the extent to which genetics contribute to individual differences in behavior and personality traits. This type of study typically involves comparing the similarity of traits between individuals who share different amounts of genetic material, such as twins and siblings.

Another type of study used to investigate nature versus nurture is twin studies. These studies compare the behavioral and personality traits of identical twins, who share 100% of their genetic material, with those of fraternal twins, who share only 50% of their genetic material. By comparing the similarities and differences in traits between these two groups of twins, researchers can determine the degree to which genetics contribute to personality development.

Additionally, adoption studies are used to investigate the role of environmental factors in shaping personality. These studies typically compare the traits of adopted children with those of their biological parents, who they share genetics with but not environment, and their adoptive parents, who they share environment with but not genetics.

Overall, investigating the nature versus nurture theories of human personality development requires the use of a combination of different types of studies. By using a multidisciplinary approach, researchers can gain a better understanding of how both genetics and environmental factors contribute to personality development.

The potential of a uniformly charged sphere is lowest at the surface of the sphere.

A uniformly charged sphere refers to a charge distribution where the charge density is the same everywhere on the sphere. In simpler terms, the magnitude of the charge is equally distributed all over the surface of the sphere. The potential at any point in an electric field is defined as the amount of work done per unit charge in carrying a small positive charge from infinity to that point. The electric potential is a scalar quantity that denotes the electric potential energy per unit charge.

The potential of a uniformly charged sphere is lowest at the surface of the sphere. This is because of the principle of equipotential surfaces which states that the electric potential at any point on the surface of a charged conductor is the same. Because of this principle, the potential inside the sphere is higher compared to the potential on the surface. In fact, the potential difference between the surface of the sphere and any point inside it is directly proportional to the distance between that point and the center of the sphere.

Answer:

4 km/hr

Explanation:

The computation of the actual velocity is shown below:

Because the path of its paddles is opposed to the current direction, the real velocity can be determined by deducting the current velocity to its velocity while paddling

So, the actual velocity is

= Upstream - downstream

= 19 km/hr - 15 km/hr

= 4 km/hr

As we can see it is in positive, so it is an upstream direction  

Answer:

since the direction of his paddles is opposite of the the direction of the current, so the actual velocity can be calculated by subtracting the velocity of current to to his velocity when paddling

v = 19 - 15

v = 4 since the answer is positive, then the direction is upstream
