A. When both teams score
B. When there is a tie
C. When the time runs out
D. When the referee decides the game is over

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:

It has low frequency and can travel through a vacuum

Explanation:

C.

Answer:

 K_f = 20000 J

Explanation:

This is a conceptual exercise, where the relationship between work and kinetic energy should be used

            W = ΔK

             W = K_f - K₀

In this case, as the car is damaged, its initial velocity is zero and therefore its initial kinetic energy is also zero.

             W = K_f

consequently the work is completely transformed into kinetic energy of the car

             K_f = 20000 J

Answer:

The Light was reflected, b.

Explanation:

If the flashlight was pointed at the mirror, it was reflected because it did not stop on the mirror or go through the mirror or reflect in different ways.

Explanation:

Vi = 0 m/s

Vf = 72 km/hr = (72×5)/18 = 20 m/s

t = 8 s

Vf = Vi + a×t

20 = 8a

a = 2.5 m/s^2

Answer:

Initial Velocity (u) = o m/s

Final Velocity (V) =(72*1000)/1*60*60 m/s

= 20m/s

time (t) =8 sec

Acceleration(a)= v-u /t

=(20-0)/8

=2.5 m/s^2

Significant figures of a number written in positional notation are digits that carry meaningful contributions to the measurement resolution of the number.

Answer:

The value of a physical quantity is expressed by a number followed by some suitable unit.

Explanation:

every measurement of a quantity is an attempt to find true value.

rules for identifying significant figures:

1)All non-zero numbers ARE significant. e.g. The number 33.2 has THREE significant figures because all of the digits present are non-zero.

2)Zeros between two non-zero digits ARE significant. e.g. 2051 has FOUR significant figures. The zero is between  2 and  5.

3)Leading zeros are NOT significant. e.g.  The number 0.54 has only TWO significant figures. 0.0032 also has TWO significant figures. All of the zeros are leading.

4)Trailing zeros to the right of the decimal ARE significant. e.g.  There are FOUR significant figures in 92.00.

5)Trailing zeros in a whole number with the decimal shown ARE significant. e.g. Placing a decimal at the end of a number is usually not done. By convention, however, this decimal indicates a significant zero. For example, "540." indicates that the trailing zero IS significant; there are THREE significant figures in this value.

Answer:

 U = 2,195 10⁵ J

Explanation:

The potential energy is

      U = m g and

in this case each person has a mass of 75 kg and the elevator has a mass of 500 kg, the total mass is

 m_total = m_elevator + 4 m_person

      m_total = 500 + 4 75

      m_toal = 800 kg

let's calculate

       U = 800 9.8 28

       U = 2,195 10⁵ J
