Answer:

its warmer than outside in winter and its colder than outside in summer

Explanation:

The perception of warmth or coolness is relative to the temperature difference between the body and the environment. Even though the temperature inside the room remains constant year-round, the relative temperature difference between the environment outside and the room can cause a subjective sensation of warmth or coolness.

Temperature is a physical quantity that measures the degree of hotness or coldness of a body or a substance. It is a scalar quantity, which means it has only a magnitude and no direction.

The SI unit of temperature is the Kelvin (K), but the temperature is commonly measured in degrees Celsius (°C) or degrees Fahrenheit (°F) as well.

The temperature difference is the numerical value of the difference between the temperatures of two objects or substances. It represents the amount of heat that flows from one object to another due to the temperature gradient between them. The temperature difference is also a scalar quantity, and its unit is usually expressed in degrees Celsius or Kelvin.

The temperature difference is important in many areas of science and engineering, including thermodynamics, heat transfer, and meteorology. It is also used to measure the efficiency of heating and cooling systems, such as air conditioners and refrigerators.

Here in this question,

This phenomenon occurs due to the relative difference in temperature between the environment outside and the temperature inside the room. The feeling of warmth or coolness is a subjective sensation that depends not only on the actual temperature but also on the difference in temperature between the person's body and their surroundings.

During the winter, the temperature outside is generally colder than the temperature inside the room which is kept at a constant temperature. When a person comes into the room from the cold outside, their body temperature is lower than the room temperature, so they feel warmer inside the room. This is because the heat from the warm room transfers to the person's body, raising their body temperature and making them feel warmer.

On the other hand, during the summer, the temperature outside is usually warmer than the temperature inside the room. When a person comes into the room from the hot outside, their body temperature is higher than the room temperature, so they feel cooler inside the room. This is because the heat from the person's body transfers to the cooler room, lowering their body temperature and making them feel cooler.

Therefore, the relative temperature difference between the environment outside and the room can cause a subjective sensation of warmth or coolness.

Answer:

Arsenic

Explanation:

Arsenic is in group 5 and period 4. Group numbers tell us the number of valence electron and period number tells us the number of shells in an element.

Answer:

Resultant Force= F1 - F2

F1= 100N

F2= 85N

Resultant Force= 100N - 85N

R.F = 15N

Workdone= Force x Displacement

Force = 15N

Displacement = 20m

= 15N X 20m

=300Nm or Joules

Answer:

1.91 × 10⁸ m/s

Explanation:

[tex]n = \frac{c}{v} \\ 1.57 = \frac{3.0 \times {10}^{8} }{v} \\ v = 1.91 \times {10}^{8} \: ms {}^{ - 1} [/tex]

The speed of light in a medium if the index of refraction is 1.57 is 1.91 * 10⁸ m/s

The refractive index of a material is the ratio of speed of light in air to speed of light in the medium. It is given by:

Refractive index(n) = speed of light in air(c) / speed of light in material(v)

Given that n = 1.57, c = 3 * 10⁸ m/s, hence:

n = c/v

1.57 = 3 * 10⁸ / v

v = 1.91 * 10⁸ m/s

The speed of light in a medium if the index of refraction is 1.57 is 1.91 * 10⁸ m/s

Answer: The human eye and brain transform light into color. Allowing us to see them.

Explanation: Light receptors within the eye turn light into color. The color that is reflected off of an object, is what we see. Hope this helps.

The apparent colors of the objects we see causes due to reflection of the light which they absorb and emit.

Reflection is the change in direction of a wavefront which occurs at an interface present between the two different media so that the wavefront of the wave returns into the medium from which it has been originated. Common examples of reflection include the reflection of light, sound wave and water waves.

The color of an object is the wavelengths of light waves that it reflects. The reflection is determined by the arrangement of electrons in the atoms of that substance which will absorb and re-emit photons of particular energy levels according to the quantum laws.

Answer:

Explanation:

During the formation of the universe some 14 billion years ago in the so-called ‘Big Bang’, only the lightest elements were formed – hydrogen and helium along with trace amounts of lithium and beryllium. As the cloud of cosmic dust and gases from the Big Bang cooled, stars formed, and these then grouped together to form galaxies.

Answer:

Explanation:

force is how hard it is pulled or pushed

Answer:

9172.8 N

Explanation:

F = ma

F = (936 kg)(9.8 m/s^2)

F = 9172.8 N

Force required to accelerate 10 kg object to 5.9 m/s/s ?

Mass = 10 kg

Acceleration = 5.9 m/s^2

Force = Mass * Acceleration

Force = 10 kg * 5.9 m/s^2

Force = 59 kg m /s^2 = 59 N
