Which of the following is an example of potential energy?
o The energy a baseball has because of its motion,
The energy a spring has by being compressed
The energy an object gains by increasing its temperature,
The energy of an electromagnetic.

Energy can neither be created nor destroyed. It can be converted from one form to another. The total energy before and after conversion remains the same. The Law of Conservation of Energy is universal.

The law of energy conservation says that energy can be transformed from one type to another type, for example, if a ball is thrown upward the kinetic energy as the ball goes upward decreases, and the potential energy increases.

Energy conversion is the process by which energy is changed from forms supplied by nature to forms used by people.

For this goal, a huge variety of tools and systems have been created over the years. A few of these energy converters are really straightforward. Early windmills, for instance, used wind's kinetic energy to drive machinery that pumped water and ground grain.

A body's kinetic energy was thought to be transformed into potential energy as it slowed down while moving upward against the pull of gravity.

Answer:

B.) 0.3s

Explanation:

The period of a wave that has a frequency of 3 Hz is 0.3s. Hence option B is correct.

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave.

Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave. Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a transverse wave.

Time period of the wave is inverse to the frequency of the wave.  

T = 1/f

T = 1/3

T = 0.333 s

Hence option B is correct.

Answer:

0.275J

Explanation:

Given parameters:

Extension  = 0.5m

Spring coefficient  = 2.2N/m

Unknown:

Energy stored in the rubberband  = ?

Solution:

The elastic potential energy is given as:

  Elastic potential energy  = [tex]\frac{1}{2}[/tex] k e²  

 k is the spring constant

e is the extension

         Elastic potential energy  = [tex]\frac{1}{2}[/tex]  x 2.2 x 0.5²  = 0.275J

used cross breeding to purposely breed plan

studied a variety of pea plant traits

studied several generations of plants

In order to breed or cross one plant with another, Mendel opened the petals and removed the anthers from the flower and dusted the pistil with pollen from the plant he wished to cross it with and covered the flower with a small bag to prevent the pollen in the air from landing in the pistil. This process is called cross pollination.

Mendel considered 7 characters of pea plant for his study and did the study for several generations.

Explanation:

Answer:

2.22m/s

Explanation:

Given parameters:

M1  = 60kg

M2  = 75kg

V1  = 0m/s

V2  = 4m/s

Unknown;

Velocity after collision  = ?

Solution:

To solve this problem, we must understand that the momentum before and after collision of the bodies must be the same;

     M1 V1  + M2 V2  = v(M1 + M2)

So;

       60 x 0  +  75 x 4  = v (60 +75)

                 300  = 135v

                   v = 2.22m/s

Given parameters:

Area of the book cover  = 0.05m²

Atmospheric pressure  = 100kPa  = 100 x 10³Pa

Unknown:

Downward force of the atmosphere on the book  = ?

Solution:

Pressure is defined as the force per unit area on a body.

 So;

 Downward force  = Atmospheric pressure x Area

  Downward force  = 100 x 10³ x 0.05  = 5000N

Answer:

it will be base on the climate change.

Explanation: so let just say tomorrow it will be cold so the atmosphere will circle on the coolest atmosphere away from the sun.

An object's position in the solar system affects both its motion and temperature. Objects closer to the Sun experience a stronger gravitational force, causing faster or slower orbits. Other planets and moons also influence an object's orbit and speed. Objects closer to the Sun receive more solar radiation and are hotter, while those farther away receive less radiation and are colder. Additionally, the composition of an object's surface can affect its temperature.

The solar system refers to the group of celestial bodies that orbit around the Sun, including planets, dwarf planets, moons, asteroids, comets, and other small bodies. It is located in the Milky Way galaxy and spans a distance of about 4.6 billion years in age. The eight planets in the solar system, in order from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The solar system is held together by the gravitational force of the Sun and is a subject of scientific study to understand the formation and evolution of our own planet and the other bodies in the solar system.

Here in the Question,

An object's position in the solar system can affect both its motion and temperature. Here's how:

Motion: The motion of an object in the solar system is affected by its distance from the Sun and the gravitational forces of other celestial bodies. An object closer to the Sun will experience a stronger gravitational force than an object farther away. This can cause the object's orbit to be faster or slower depending on its position. Additionally, the gravitational pull of other planets and moons can affect the object's orbit and speed.

Temperature: An object's temperature in the solar system is affected by its distance from the Sun and the composition of its surface. Objects closer to the Sun receive more solar radiation and thus have a higher temperature. Objects farther away receive less radiation and are colder. Additionally, the composition of the object's surface can affect its temperature. For example, objects with high albedo (reflectivity) will reflect more solar radiation and have a lower temperature than objects with low albedo.

Therefore, an object's position in the solar system has a significant impact on its motion and temperature. By studying the positions of celestial bodies and their effects on each other, scientists can gain a better understanding of the dynamics of the solar system and the properties of objects within it.

Explanation:

Answer:

The spring constant is k=7031.25

Explanation:

We start by using the conservation of mechanical energy:

Ui + Ki = Uf + Kf

the Ui (initial potential energy) is zero since the spring is relaxed.

In the final situation, the Kf (final kinetic energy is zero since the car and spring are NOT in motion)

Then we have:

[tex]K_i=U_f\\\frac{1}{2} m*v^2=\frac{1}{2} k*(\Delta x)^2\\\frac{1}{2} 2000*15^2=\frac{1}{2} k*(8)^2\\k=7031.25[/tex]

Answer:

magnitude of v = 2.5 m/s, and in the same direction as the initial velocity of the 5 kg ball.

Explanation:

We use conservation of linear momentum in an elastic collision to solve for the unknown velocity v:

Pi = Pf

5 kg * 5 m/s + 10 kg * 0 m/s = 5 kg * 0 m/s + 10 kg * v

25 kg m/s = 10 kg * v

v = 25/10 m/s

v = 2.5 m/s

and in the same direction as the initial velocity of the 5 kg ball.
