Answer:

c. earth rotates on it tilted axis and orbit around the sun at the same time​

Explanation:

Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.

This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.

Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time​

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.

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

As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.

The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.

According to circle graph:

Total number of student in the particular school = 2π radian.

So, one-fourth of total number of student in the particular school = 2π/4 radian

= π/2 radian.

Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

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: The fork feels colder when you touch it because Steel conducts thermal energy better than plastic. The correct statement is 1

Explanation:

The ability of a material to transfer heat energy in an environment is known as thermal conductivity. It feels cooler to touch a steel spoon than a plastic spoon found in the same temperature because steel which is a type of metal is a highly efficient thermal conductor than spoon which is a plastic.

Metals can be defined as those substances which forms positive ion in a chemical reaction by lossing it's electrons. It has the following properties:

--> it is solid at room temperature

--> it has high melting point

--> it has high boiling point and

--> it is malleable.

Metals are said to be good thermal conductor because they contain free flowing conduction electrons. Therefore, when you touch a steel spoon and plastic spoon, it feels cooler because the steel metal is able to conduct heat away from your hand faster than the plastic which is a poor conductor of heat.

Answer:

1. Steel conducts thermal energy better than plastic.

Explanation:

Both objects are at the same temperature, and when you touch them, you feel the steel to be colder.

This happens because steel is a better thermal conductor, then when you touch it, it "steals" more thermal energy from you than the plastic.

As the amount of thermal energy transmitted is greater for the steel, you will feel it to be colder.

Then the correct option is the first one, steel conducts thermal energy better than plastic.

The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

Since

Length L = 6.25 m

g = 9.8 m/s²

So,

T = 2π√(L/g)

T = 2π√(6.25 / 9.8)

T = 5.01 sec

Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
