Answer:

i think a species of bird will die or move to a new forest

Answer:

It actually depends.

Explanation:

in the case of a metal ur hand will absorb the heat (but it depends on the temperature, this ans favours hot and cold but not neutral or room temperature), in the case of human to human I think no heat transfer will take place, in the case of liquids(for hot temperature ,it would even for cold but not room).

It basically involves application

Answer:

The temperature scale on which water freezes at 0 and boils at 100. Thermal energy that is transferred from one substance to another; moves from warmer to cooler objects. The transfer of heat by direct contact; occurs when energy is transferred by collisions between particles.

Explanation:

When thermal energy is transferred  both kinetic and potential energy increases.

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.There  are three types of thermal energy transfer:1) conduction 2) convection 3) radiation

reduce the air drag

pls mark it as brainloest

Answer:Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.

Explanation:So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

Extra explanation: All waves can be defined in terms of their frequency and intensity. c = λν expresses the relationship between wavelength and frequency.

Answer:

Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

Explanation:

Momentum is the product or multiplication of a body's mass and its speed.

Since all options have the mass and speed in the same units, there is no need for conversion.

Explanation:

Answer:

Gases have three characteristic properties: 1. they are easy to compress, 2. they expand to fill their containers, and 3.they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.

Explanation:

Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.

Answer:

490000J

Explanation:

Given parameters:

Mass of boulder  = 1000kg

Height of cliff = 50m

Acceleration due to gravity  = 9.8m/s²

Unknown:

Potential energy  = ?

Solution:

Potential energy is due to the position of a body. It is expressed as;

        P.E  = mgH

m is the mass

g is the acceleration due gravity

H is the height

  Now insert the parameters and solve;

            P.E  = 1000 x 9.8 x 50  = 490000J

Data:  

m = 1000 kg

h = 50 m

g = 9.8 m/s^2

Find:  

P.E = ?

Formula:  

P.E = mgh

Solution:  

P.E = mgh

P.E = (1000)*(9.8)*(50)

P.E = 490000 J

Result:

P.E = 490000 Joule

Answer:

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

Explanation:

Answer:

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

Explanation:  I got it right on edge2021 :)

s

average we find the average times for each checkpoint

point 1   [tex]t_{avg}[/tex]   = 2.07 s

point 2 t_{avg} = 3.16 s

point 3 t_{avg} = 4.11 s

point 4 t_{avg} = 4.92 s

given parameters

     * Graph with time for each interval

to calculate

 * average time for each interval (checkpoint)

The average of a magnitude is

          [tex]t_{avg} = \sum \frac{t_i}{n}[/tex]

where [tex]t_{avg}[/tex] in the average time, t_i each time the magnitude is measured and n the number of times the measurement is repeated for the same point.

The table shows the times measured for each interval

measurement       time (s) in interval,

                               1     2         3       4

1                         2.02    3.17   4.12    4.93

2                        2.05    3.07  3.98   4.81

3                         2.15    3.25  4.23    5.01

we look for the average time to get married check point

point 1

          t_{avg} = (2.02 + 2.05 + 2.15) / 3

          t_{avg} = 2.07 s

Point 2

          t_{avg} = (3.17 +3.07 + 3.25) / 3

          t_{avg} = 3.16 s

point 3

          t_{avg} = (4.12 + 3.98 + 4.23) / 3

          t_{avg} = 4.11 s

checkpoint 4

           t_{avg} = (4.93 + 4.81 + 5.01) / 3

           t_{avg} = 4.917 s

We use the criterion of significant figures for the sum, which is stable that the result must be given with the number of decimal places of the figure that I have the least.

           t_{avg} = 4.92 s

the average allows to find the average times for each check point

point 1 tavg = 2.07 s

point 2 tavg = 3.16 s

point 3 tavg = 4.11 s

point 4 tavg = 4.92 s

Answer:

Explanation:

ball ( it sound like thup thup it is softly harsh in voice )

book ( tak tak it is hard in voice )

bed ( pat pat it is soft in voice )

Door, window, picture, floor,stairs, wall, desk, backpack, paper, bed all of these produce different sound.

The term sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them.

A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates by an elastic material medium.

The vibration of an object creates sound, which travels from one place to another by a medium. Vibration is the phrase used to explain an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.

Therefore, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.
