Answer:

its when a liquid, prolly water, turns into a vapor !!

Explanation:

and nice pic uwu

A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.

Latent heat is a form of energy held in the evaporated water when it evaporates and cools.

Evaporation plays a significant role in the energy exchange that results in atmospheric motion, affecting weather and climate in the Earth-atmosphere system.

The particles with the highest kinetic energy are the first to evaporate from a liquid.

Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

Explanation:

The formula for kinetic energy  Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.

If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.

Explanation:

The four regions of the earthworm are, A is the anterior end,B is the dorsal side, C is the posterior end, and D is the ventral side.

Earthworms are common soil dwellers who are both safe and useful. Earthworms help plants flourish by collapsing dead and decaying organic debris into rich humus soil.

They also aerate the soil and enhance flow by digging small canals and holes.

The four regions of the earthworm are;

A is the Anterior end

B is the Dorsal side

C is the Posterior end

D is the Ventral side

Hence all the regions are clearly defined with the help of digrame.

Answer:

to collide with (something) with a moderately forceful impact; thump.

Explanation:

Answer:

Distance, S = 15m

Explanation:

Given the following data;

Mass = 4kg

Force = 10N

Initial velocity = 5m/s

Final velocity = 10m/s

To find the distance;

First of all, we would calculate the acceleration

Force = mass * acceleration

10 = 4*acceleration

Acceleration = 10/4

Acceleration = 2.5m/s²

Now to find the distance, we would use the third equation of motion.

[tex] V^{2} = U^{2} + 2aS [/tex]

Where;

S represents the displacement measured in meters.

Substituting into the equation, we have;

10² = 5² + 2*2.5*S

100 = 25 + 5S

5S = 100 - 25

5S = 75

Distance, S = 75/5

Distance, S = 15m

Answer:

4 N

Explanation:

mass = 2 kg

acceleration = 2 m/s^2

Force = mass * acceleration

         = 2 *2

         = 4 N

Answer:

Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”

Explanation:

Volcanoes are found around tectonic plates because the convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other, plates converge and the plates move together, also known as ridge push, therefore mountains and volcanoes are formed

The jet stream speed used by the computer is 142.[tex]\overline {857142}[/tex] km/h

Explanation:

The given parameters are;

The distance between the two cities the plane flies = 4,000 km

The difference in flight times for outgoing and return flights = 70.0 min

We note that 70 min = 70 min × 1 h/60 min = 7/6 h

The airspeed recommended by the airline computer = 1,000 km/h

Let 'a' represent the jet stream speed

The time it takes the plane moving in the same direction as the jet stream between the two cities, 't₁', is given as follows;

[tex]t_1 = \dfrac{4000}{1000 + a}[/tex]

The time it takes the plane moving in the opposite direction as the jet stream between the two cities, 't₂', is given as follows;

[tex]t_2 = \dfrac{4000}{1000 - a}[/tex]

The difference in flight times for outgoing and return flights, Δt = t₂ - t₁

Therefore, we have;

[tex]\Delta t = t_2 - t_1 = \dfrac{4000}{1000 - a} - \dfrac{4000}{1000 + a} = \dfrac{7}{6}[/tex]

From which we get;

[tex]-\dfrac{8000 \cdot a}{a^2 -1,000,000} = \dfrac{7}{6}[/tex]

By cross multiplying, we have;

-48,000·a = 7·a²- 7,000,000

∴ 7·a² + 48,000·a - 7,000,000 = 0

Factorizing with a graphic calculator gives;

(7·a - 1,000)·(a + 7,000) = 0

∴ a = 1,000/7, or a = -7000

Therefore, the jet stream speed the computer is using, a = 1,000/7 km/h = 142.[tex]\overline {857142}[/tex] km/h.

Answer:

the advantage gained by the use of a mechanism in transmitting force specifically : the ratio of the force that performs the useful work of a machine to the force that is applied to the machine.

Explanation:

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever.

Answer:

The time it takes to stop is 13.75 seconds

Explanation:

A body moving with constant acceleration, 'a', for a time, 't', has a final velocity, 'v', given by the following kinematic equation;

v = u + a·t

Where;

v = The final velocity of the body

a = The acceleration of the body

t = The time of acceleration (accelerating period) of the body

u = The initial velocity of the body

The given parameters for the acceleration of the car are;

The initial velocity of the car, u = 0 m/s (a car starting from rest)

The constant acceleration of the car, a =  5.5 m/s²

The acceleration duration, t = 6 s

Therefore, we have;

The final velocity of the car after the acceleration, v = 0 m/s + 5.5 m/s² × 6 s = 33 m/s

The final velocity of the car after the acceleration, v = 33 m/s

When the car slows down uniformly, and comes to a stop (final velocity, v₂ = 0 m/s), it has a constant negative acceleration, (deceleration) '-a₂'

The given parameters when the car slows down  are;

The deceleration, -a₂ = 2.4 m/s²

The final velocity, v₂ = 0 m/s

The initial velocity, u₂ = v = 33 m/s

The time it takes to stop = t₂

-a₂ = 2.4 m/s²

∴ a₂ = -2.4 m/s²

From, v = u + a·t, we have;

v₂ = v + a₂·t₂

By plugging in the values of the variables, we have;

0 m/s = 33 m/s + (-2.4 m/s²) × t₂

∴ 2.4 m/s² × t₂ = 33 m/s

t₂ = 33 m/s/(2.4 m/s²) = 13.75 s

The time it takes to stop, t₂ = 13.75 seconds

Explanation:

Answer:

125 joules

Explanation:

The velocity of the runner having a mass of 75 kg will be 9.93 m/s.

The energy of the body by virtue of its motion is called its kinetic energy.

Given is velocity of a runner who has a mass of 75 kg and 3,700 Joules of energy.

The kinetic energy of the body is given by the following formula -

KE = 1/2 mv².

Substituting the values -

3700 = 1/2 x 75 x v²

7400 = 75 x v²

v² = 7400/75

v² = 98.66

v = 9.93 m/s

Therefore, the velocity of the runner having a mass of 75 kg will be 9.93 m/s.

Answer:

Temperature or thermal energy.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, the temperature or thermal energy of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.​

Gamma rays of electromagnetic radiation with a relatively high amount of energy is used to sanitize lab goggles.

A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays.

Moreover, gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.

Therefore, both x-rays and gamma rays are forms of high-frequency (high-energy) ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. Ionizing radiation can damage the DNA (genes) inside a cell. Sometimes this can lead to cancer later on.
