Answer:

b. the cylinder

Explanation:

From the information given:

We understood that the mass of the sphere, cylinder, and rod length is the same with the same angular speed.

Taking their moments:

For the solid sphere; [tex]\text{The moment of inertia :}[/tex] [tex]I_s[/tex] = [tex]\dfrac{2}{5} \times m \times r^2[/tex]

The moment of inertia of the cylinder, [tex]I_c = 0.5\times m \times r^2[/tex]

The moment of inertia of rod, [tex]I_r =\dfrac{ m * r^2 }{12}[/tex]

The rotational kinetic energy is directly corresponding to the moment of inertia.

Thus, the cylinder has the greatest rotational kinetic energy.

Answer is

53.3cm I think

53.3cm will be the focal length of converging lens.

The light beams in this instance diverge after passing through the lens. A virtual image is created when diverging refracted rays collide.

All light rays can be followed backwards until they intersect to determine the image's location. The extended refracted beams' point of intersection, which appears to all observers to be the refracted rays' point of divergence, is the image point.

1/(-15) = 1/v + 1/(-45)

→ -1/15 = 1/v - 1/45

→ -1/15 + 1/45 = 1/v

→ (-3 + 1)/45 = 1/v

→ -2/45 = 1/v

→ -45/2 = v

→ 53.3 cm = v

Therefore, 53.3cm will be the focal length of converging lens.

Answer:

Earth's surface is broken into large pieces that are slowly shifting. ... This movement creates many of Earth's landforms, such as mountains, rift valleys, and volcanoes. According to the theory of plate tectonics, 250 million years ago all of Earth's landmasses were clustered into one supercontinent, known as Pangea.

or

Presently the plates are moving towards each other and will eventually merge into one landmass once again. Presently Africa I moving towards Europe and Asia and will merge with that landmass, closing the Mediterranean Sea. When plates move towards each other extensive fold mountain ranges will form; a modern day example is the Himalayan mountain range. This type of movement will impact ocean currents as we know it and bring about a dramatic change in the climate. Disruption of currents and the closure of some water ways and oceans will lead to the extinction of some species. Leaving only those who are able to adapt to the new climatic conditions.

Explanation:

you can choose either one

Answer:

Based on what I have learned this year and past knowledge, I think they will move in a combination of two. The tectonic plates move around the planet but move very slowly, only a few centimeters per year, which plays a big part in the picture. If you look at California, It's splitting! But who is to say that the continents will not cluster to another land as it spreads out. There's also not enough space on earth for every piece of land. But when they do end up clustered together, mountains will be formed, and if they spread out, faults will be created. So I think in 250 million years we will have another supercontinent like Pangea. I also believe that there will be many new geographical changes, including volcanoes, more mountains, and deeper oceans. This will also cause new Invasive species and the destruction of man-made buildings.

Monosaccharides consist of a simple sugar; that is, they have the chemical formula C 6 H 12 O 6. Disaccharides are two simple sugars. Oligosaccharides are three to six monosaccharide units, and polysaccharides are more than six.

Answer:

563.86 N

Explanation:

We know the buoyant force F = weight of air displaced by the balloon.

F = ρgV where ρ = density of air = 1.29 kg/m³, g = acceleration due to gravity = 9.8 m/s² and V = volume of balloon = 4πr/3 (since it is a sphere) where r = radius of balloon = 2.20 m

So, F = ρgV = ρg4πr³/3

substituting the values of the variables into the equation, we have

F =  1.29 kg/m³ × 9.8 m/s² × 4π × (2.20 m)³/3

= 1691.58 N/3

= 563.86 N

Mars2   illuminated side of the planet is very  heat, dark side very cool

Venus 2 a warm planet with a constant temperature across the entire surface

Explanation:

For this hypothetical case, when changing the planets they are changed with their current characteristics.

Case of Mars2

In this case, there is a planet with a very thin atmosphere, so the solar radiation reaches the ground without damping it, causing a lot of noise, so the illuminated side of the planet is very heat and when the dark side turns due to the little atmosphere it loses everything the heat for which it is very cold.

This thermal stress between the two sides of the planet continues constantly creating possible fruit trees in its rocky systems.

Case of Venus 2

The planet has a high atmospheric density, but it is very far from the sun, so the amount of radiation that arrives slightly warms the planet, but due to the thin atmosphere the losses for the dark period are very small, so the entire planet it is heated until it reaches an almost uniform temperature over its entire surface.

In this case we have a warm planet with a constant temperature across the entire surface, regardless of which side is lit.

Answer:

Reflection

the angle of incidence is equal to angle of reflection

According to the law of reflection, the angle of incidence is equal to the angle of reflection. Hence option B is correct.

Reflection is the change of direction of the wave at the interface which separates two media. it get incident on the other media and get return to the same media is called as reflection. Common examples include the reflection of light, sound and water waves.

we can see that in the dark room when we incident light on the mirror, the direction of the light changes at the point of the incidence. in the scientific language we can say that light has reflected from the surface of the mirror. in this case  angle of incidence is always equal to angle of reflection.

Any mirror bounce back the incident light. therefore it is used to see our face. it reflects almost all the light to same medium from which light has been incident.

Hence option B is correct.

Answer:

Explanation:

Answer:

The final speed will be "0.65 m/s".

Explanation:

The given values are:

[tex]m_a[/tex] = 27.4 kg

[tex]m_b[/tex] = 49.4 kg

[tex]v_a[/tex] = 1.23 m/s

[tex]v_b[/tex] = 0.759 m/s

By using the law of conservation of momentum, we get

⇒ [tex]P=\sqrt{P_1^2+P_2^2}[/tex]

⇒     [tex]= \sqrt{(m_av_a)^2+(m_bv_b)^2}[/tex]

On substituting the values, we get

⇒     [tex]=\sqrt{(27.4\times 1.23)^2+(49.4\times 0.759)^2}[/tex]

⇒     [tex]=\sqrt{1135.82+1405.84}[/tex]

⇒     [tex]=50.41 \ kg-m/s[/tex]

As we know,

⇒ [tex]P=(m_1+m_2)v[/tex]

Then,

⇒ [tex]v=\frac{P}{m_1+m_2}[/tex]

On substituting the values, we get

⇒    [tex]=\frac{50.41}{27.4+49.4}[/tex]

⇒    [tex]=\frac{50.41}{76.8}[/tex]

⇒    [tex]=0.65 \ m/s[/tex]

They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time.

Mutation is when there is a particular change in the bases of the DNA, this changes how enzymes and proteins work, and there may be a chance that this change will be helpful.

Answer:

It’s behavioral which is learned via classical conditioning it’s when the neutral or the conditioned stimulus becomes something that causes fear to all organisms

A person acquire a fear of or aversion to something even though it has no negative effect on him or her due to the classical conditioning.

Any thing which has bad effects or something wrong can happen with the doing. The effect is the negative effect.

We assume that we do not fear, a dog that triggers a fear response, such as being bitten.

If we are exposed to the object or such situation we fear over and over without having any negative outcome. The  classical conditioning can truly help unlearn the fear.
