Answer:

How does energy travel?

One way the energy can travel is through radiation. An object can radiate energy in the form of electromagnetic waves, for example when a strong light is turned on and you can feel some heat coming from it, or when you walk under the sunlight and you can feel the heat in your skin.

Where is the initial source of energy in our solar system?

In the solar system, the source of energy comes from the Sun, and the sun irradiates that energy to all the nearby objects.

What is the process that gives off energy from the sun called?

The process is called radiation, this is all the energy that comes from the sun in the form of different electromagnetic waves (light in the visible range, UV rays, etc...)

The Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.

Newton's third law of motion, states that, action and reaction are equal and opposite.

The force exerted on the ball when Stephanie spikes is equal to the reaction the ball exerts back on Stephanie. As the force Stephanie applied increases, the reaction she receive from the ball increases as well and the more pain she will feel.

Thus, we can conclude that, the Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.

Answer: When a material is heated or cooled, two changes may happen to the particles within the material: Chemical bonds between the particles may form, break or stretch. There is a change in the chemical potential store of energy in the material. The material will heat up or cool down as the particles within it gain or lose speed.

The right characteristics to be used for the classification include:

-dense and solid

-very large  

-located near a star

Explanation:

The above listed characteristics are part of the characteristics used in classifying a planet as a habitable planet or non-habitable one. When a planet is closer to a star which revolves around it, this helps in supplying the needed light to it.

Answer:

Increase in strength of hurricanes

Explanation:

A possible result of rising ocean temperatures caused by global warming is an increase in the strength of hurricanes, which is the second option. As the ocean temperatures increase, more energy is available to fuel hurricanes, making them stronger and potentially more destructive.

Global warming is causing the earth's climate to change, which is having a significant impact on the world's oceans. As the temperature of the oceans increases, a variety of effects can occur. One of the most well-documented impacts is the increase in the strength of hurricanes. Hurricanes form over warm ocean waters, and as the water temperature rises, it provides more energy to the storm, making it more powerful. 

Hence, a possible result of rising ocean temperatures caused by global warming is an increase in the strength of hurricanes, which is the second option.

Answer:

See the answer below.

Explanation:

The latent heat of fusion is defined as the amount of energy needed to make a phase change from solid to liquid. And it can be calculated by means of the following expression:

[tex]Q_{fusion}=m*Dh[/tex]

where:

Qfusion = Heat Energy [J]

m = mass = 0.65 [kg]

Dh =  latent heat fusion = 330000[J/kg]

[tex]Q_{fusion}=0.65*330000\\Q_{fusion}=214500[J][/tex]

2)

We know that energy can be calculated from power, where power is defined as the relationship between energy over time.

[tex]P=E/t[/tex]

where:

P = power = 60 [w]

E = energy [J]

t = time = 5 [min] = 300 [s]

[tex]E=P*t\\E=50*300\\E=15000[J][/tex]

The mass change due to the process is equal to:

[tex]m=282-274\\m=8[g]=0.008[kg][/tex]

Now using the following equation for the latent heat of Fusion, we can calculate this value:

[tex]Q=m*Dh\\Dh =Q/m\\Dh=15000/0.008\\Dh=1875000[J/kg][/tex]

All forces are either balanced or unbalanced and each force acts in different ways.

Answer:

After 11.9 seconds, the velocity will increase by approximately 2.7 m/s

Explanation:

Ignoring friction, we can simply say that the speed will increase by

11.9s × 473.3N / 2068.3kg

Which can be expressed as:

11.9s × 473.3kg·m/s² ÷ 2068kg

= (11.9 × 473.3 ÷ 2048.3) (kg·m/s² × s ÷ kg)

≈ 2.7 m/s

1. 75 speed, 2. 90 second = 1hr. 30 second. 3. 125 = 1hr 60 seconds 4.

Answer:

v = 1.5 m/s

Explanation:

m = 85 kg

p = 125 kg m/s

v = ?

p = m v

125 kg m/s = (85 kg) (v)

v = (125 kg m/s) / (85 kg)

v = 1.47 m/s
