During which change of states do atoms lose energy?

Answer: C. rapid evaporation of water in the soil :)

A possible result of higher air temperatures caused by global warming is rapid evaporation of water in the soil.

Global warming is a phenomenon that has been registered around the world during the last decades. It refers to a progressive increase in the average temperatures of the oceans and the Earth's atmosphere, which has consequences for flora and fauna, in addition to impacting critical sectors such as agribusiness.

Among the consequences of global warming are melting ice, rising sea levels, desertification, changes in rainfall, floods and reduced biodiversity.

Answer:

The girl must sit 5 m on the other side of the seesaw.

Explanation:

Given;

mass of the boy, = 75 kg

mass of the girl, = 50 kg

distance of the boy from the pivot, = 2 m

let the distance of the girl from the pivot = d

    <-------------2m-------------><-------------d-------------->

-----------------------------------------------------------------------------------

     ↓                                  Δ                                   ↓

     75                                                                      50

Apply the principle of moment, about the pivot;

clockwise moment = anticlockwise moment

75 x 2 = 50 x d

150 = 50d

d = 150 / 50

d = 3 m

The distance of the girl from the pivot is 3 m.

Therefore, the girl must sit ( 2m + 3m ) on the other side of the seesaw.

Answer:

im pretty sure its d

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.

Answer:

The current flowing the heating element is 0.868 amperes.

Explanation:

Ohm's law states that voltage is directly proportional to current. In other, words, we say that:

[tex]V \propto R[/tex]

[tex]V = i\cdot R[/tex] (1)

Where:

[tex]V[/tex] - Voltage, measured in volts.

[tex]i[/tex] - Current, measured in amperes.

[tex]R[/tex] - Resistance, measured in ohms.

If we know that [tex]V = 230\,V[/tex] and [tex]R = 265\,\Omega[/tex], then the current that flows through the heating element is:

[tex]i = \frac{V}{R}[/tex]

[tex]i = \frac{230\,V}{265\,\Omega }[/tex]

[tex]i = 0.868\,A[/tex]

The current flowing the heating element is 0.868 amperes.

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]

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

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...)

Explanation:

Answer:

1.07 x 10⁻⁸N

Explanation:

Given parameters:

Mass 1 = 200kg

Mass 2  = 500kg

Distance of separation  = 25m

Unknown:

Gravitational attraction between the two bodies  = ?

Solution:

To solve this problem, we use the equation of the universal gravitation;

                 F  = [tex]\frac{G mass 1 x mass 2}{r^{2} }[/tex]  

G is the universal gravitation constant  = 6.67 x 10⁻¹¹Nm²kg⁻²

r is the distance

 Now insert the parameters and solve;

    F  = [tex]\frac{6.67 x 10^{-11} x 200 x 500 }{25^{2} }[/tex]   = 1.07 x 10⁻⁸N

Given:

Mass of objects,

Distance,

We know,

As we know the relation,

→ [tex]F_G = \frac{Gm_1m_2}{r^2}[/tex]

By substituting the values, we get

        [tex]= 6.67\times 10^{-11}\times \frac{200\times 500}{(25)^2}[/tex]

        [tex]= 1.0672\times 10^{-8} \ N[/tex]

Thus the above answer is right.

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.

Explanation:

Given that,

Mass of the rider, m = 60 kg

Let the radius of the circle, r = 30 cm = 0.3 m

Let the velocity, v = 20 m/s

We need to find the centripetal force needed to keep the rider in a circular path. It can be given by :

[tex]F=\dfrac{mv^2}{r}\\\\F=\dfrac{60\times (20)^2}{0.3}\\\\F=80000\\\\\text{or}\\\\F=8\times 10^4\ N[/tex]

So, the required force is [tex]8\times 10^4\ N[/tex].

If it's not C then it HAS to be B.

Explanation:

By deductive reasoning.

Answer:

416.6 KG

Explanation:

Due to the mass being missing from the equation you divide the force by the acceleration

Answer:

Solution:

i) Heat supplied by heater = Heat gained by water = m * c*theta = 0.12Kg * 4200 * 10 = 5040Joules in 2 minutes.

ii) Power = Energy/time = 5040J/(2 * 60seconds) = 5040J/120seconds = 42Watts.

(iii) Heat supplied to the 70g of water = m * c * theta = 0.07Kg * 4200 * 9K = 2646J

(iv) Heat supplied by heater = Heat gained by 70g of water + Heat supplied to the metal vessel.

But,from our calculations above,

Heat supplied by heater = 5040J ......and

Heat supplied to the 70g of water = 2646J

.: substituting the values,we have that :

5040J = 2646J + Heat supplied to the metal vessel.

5040J - 2646J = Heat supplied to the metal vessel.

.: Heat supplied to the metal vessel = 2394J.

(v) Heat gained by metal vessel = Heat capacity of the vessel * theta.

2394J = Heat capacity of the vessel * 9K

.: Heat capacity of the vessel = 2394/9 = 266(Joule per Kelvin)

(vi) Using the formula:

Heat Capacity = mass * specific heat capacity

.: Specific heat capacity = Heat Capacity/mass = 266/0.55 = 484(Joules per Kilogram per Kelvin)
