Answer:wind

Explanation:

The natural resource that is renewable is wind. Explanation on wind as a renewable resource can be found below.

Renewable resources are those resources that is replenished or replaced by natural processes at a rate comparable to its rate of consumption by humans or other users.

Renewable resources cannot be exhausted as a result of use, unlike, their non-renewable counterparts.

Examples of renewable natural resources are as follows:

Therefore, the natural resource that is renewable is wind.

Answer:

Yes,in fact visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets', called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).

Answer:

Check the diagram from the photo

Explanation:

Answer:

3540.5N

Explanation:

Step one:

given data

mass m= 0.196kg

speed  v= 31m/s

distance r= 5.32cm = 0.0532m

Step two

The expression relating force, mass, velocity and distance is

F= mv^2/r

substitute we have

F=0.196*31^2/0.0532

F=0.196*961/0.0532

F=188.356/0.0532

F=3540.5N

When I got this question I had to draw it out so if you have to do that, draw 3 stick figures holding hands, one representing the mother, father, and daughter. Then you write their weights on top of them and then draw an arrow pointing from the father to the mother.

Explanation:

use this formula :

[tex]a_{y}[/tex] = [tex]\frac{Fdadshandy}{msys}[/tex]

then you fill it in :

[tex]a_{y}[/tex] = [tex]\frac{100N}{35.5kg+58.2kg}[/tex]

[tex]a_{y}[/tex] = [tex]\frac{100N}{93.7kg}[/tex]

[tex]a_{y}[/tex] = [tex]1.0672[/tex] [tex]m/s^{2}[/tex]

then you multiply that with the daughters weight :

[tex]T_{2} x= m_{2} a_{y}[/tex]

[tex]T_{2} x = 35.5kg (1.0672 m/s^{2})[/tex]

[tex]T_{2} x = 37.89N[/tex]

and that's the answer :) : 37.89N

Explanation:

The microwave radiation referred to in this context is radiation that was released as matter formed in the early universe. Therefore option A is correct.

Microwave radiation, also known as cosmic microwave background radiation (CMB), is a faint radiation that permeates throughout the universe.

It is considered to be the remnants of the thermal radiation released shortly after the Big Bang, during a phase called recombination. At this time, the universe transitioned from a hot, dense plasma to a state where neutral atoms could form, allowing photons to travel freely.

The cosmic microwave background radiation is isotropic, meaning it is uniformly distributed in all directions, and it has a characteristic temperature of approximately 2.7 Kelvin (-270.45 degrees Celsius).

It was first detected in 1965 by Arno Penzias and Robert Wilson, who were awarded the Nobel Prize in Physics for their discovery.

The presence of cosmic microwave background radiation provides strong evidence for the Big Bang theory and helps to support the understanding of the early universe's formation and evolution.

It serves as an important tool for studying cosmology and provides insights into the structure, age, and composition of the universe.

Answer:

Eliminate D as there is no nonconservative force, then look at each energies before and after. The speed of the book will increase, so kinetic energy is increasing. The height of the book is increasing, so gravitational potential energy is increasing. However, since the spring is becoming decompressed, the elastic potential energy is decreasing.

The work done by Shawn in moving the tire is 36,000 J

Explanation:

Given;

net force applied by Shawn , F = 1200 N

distance he moved the tire, d = 30 m

The work done by Shawn in moving the tire is calculated as;

W = Fd

Substitute the given values and solve for Work done;

W = 1200 x 30

W = 36,000 J

Therefore, the work done by Shawn in moving the tire is 36,000 J

Explanation:

Hooke's Law: Fe = kx

x = Fe / k = (22.0N) / (4.00N/cm) = 5.50cm.

Answer:

A: Air pressure decreases as air density increases

Explanation:

Pressure is a force exerted on or against an object by being in contact with a substance. Thus, air pressure is due to the bombardment of the air (gas) particles with a surface. Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume.

If that Explanation does not make any sense let me make it easier.

The air at the top of a mountain is cooler than the air at the bottom. This temperature difference is due to a phenomenon that occurs in Earth’s atmosphere. Air rises and sinks based on differences in temperature and pressure. Here’s a quick experiment that will help explain the role of pressure.Take in a deep breath as if you were ready to blow out birthday candles. Puff your cheeks with air like a chipmunk. Hold it for a few seconds, and then blow the air slowly from your cheeks.Cold air sinks while warm air rises because cold air is denser than warm air. When a lot of cold air sinks, it creates an area of high air pressure where it hits the surface. This high-pressure air flows to an area of low pressure, creating wind. When this air warms, it rises up into the atmosphere.Temperature decreases as altitude increases. That’s why a mountain peak may be covered with snow while the bottom of the mountain is full of green plants and trees. When warm air rises into the atmosphere, it cools. The density of the air increases as it cools, which eventually creates an area of high pressure and starts the cycle again.

If not for this phenomenon of air rising and sinking in the atmosphere, there would be no wind or weather.

I hope that helped!

Explanation:

Answer:

0.55 m/s².

Explanation:

From the question given above, the following data were obtained:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

Force (F) is defined as the product of mass (m) and acceleration (a). Mathematically, the force (F) can be represented as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can calculate the acceleration of the ball as follow:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

F = ma

1.1 = 2 × a

Divide both side by 2

a = 1.1 / 2

a = 0.55 m/s²

Therefore, the acceleration of the ball is 0.55 m/s²

Answer:

B. It can be answered using measurements.

Explanation:

Scientific inquiry can be defined as the various ways, techniques and approach used by scientists to study the world and provide a detailed description (information) based on the empirical evidence derived from the investigation.

Measurements can be defined as a technique which typically involves the process of identifying and determining the dimensions, quality and quantity of a physical object.

Hence, the statement which best describes a characteristic of a question that can be answered through scientific inquiry is that, it can be answered using measurements. Using scientific inquiry to answer questions entails using measurements to propose specific and evidential explanations, as well as back up theories associated with the question.

how far around a circle is once around in degees?

1.5 * 360 = 540°

Answer:

29.41%

Explanation:

Given that,

In 1630 at the beginning of European settlement, about 425,000,000 hectares of the United States were covered with trees.

By 2017, the area covered by trees was reduced to 300,000,000 hectares.

We need to find the percentage decrease in the area covered by trees between 1630 and 2017.

The percentage decrease in any value is given by :

[tex]\%=\dfrac{300,000,000 -425,000,000 }{425,000,000 }\times 100\\\\=29.41\%[/tex]

So, the percentage decrease in the area covered by the trees is 29.41%.

Answer:

A blackbody, or Planckian radiator, is a cavity within a heated material from which heat cannot escape. No matter what the material, the walls of the cavity exhibit a characteristic spectral emission, which is a function of its temperature.

Example:

Emission from a blackbody is temperature dependent and at high temperature, a blackbody will emit a spectrum of photon energies that span the visible range, and therefore it will appear white. The Sun is an example of a high-temperature blackbody.
