Two ice skaters approach each other at right angles. Skater A has a mass of 27.4 kg and travels in the x direction at 1.23 m/s. Skater B has a mass of 49.4 kg and is moving in the y direction at 0.759 m/s. They collide and cling together. Find the final speed of the couple. Answer in units of m/s.

Answers

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]

Answers

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.

What is Reflection ?

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.

Suppose a mad scientist went back in time to the beginning of the solar system and caused the newly formed Mars and Venus to switch places. So now there is a Venus-sized planet where Mars was (let's call it Venus 2), and a Mars-sized planet where Venus was (let's call it Mars 2). How would these hypothetical new planets, Mars 2 and Venus 2, turn out in this alternate time line

Answers

Answer:

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.

A meteorologist plans to release a weather balloon from ground level, to be used for high-altitude atmospheric measurements. The balloon is spherical, with a radius of 2.20 m, and filled with hydrogen. The total mass of the balloon (including the hydrogen within it) and the instruments it carries is 21.0 kg. The density of air at ground level is 1.29 kg/m3. (a) What is the magnitude of the buoyant force (in N) acting on the balloon, just after it is released from ground level

Answers

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

Earth’s surface is broken into large pieces that are slowly shifting. This gradual process, known as plate tectonics, accounts for movement of entire continents over time. During the past century, geologists have found multiple lines of evidence that support the theory of plate tectonics, including the mechanism that drives the plates’ motion—sea floor spreading. As a result, sections of Earth’s crust are constantly being pulled apart or pushed together. 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. Based on the past and current movements of Earth’s plates, predict how the location of the continents might shift during the next 250 million years. Do you think they’ll spread out, cluster together, or move in a combination of the two? What types of landforms do you anticipate forming as a result? What effect, if any, do you anticipate this movement will have on life on Earth?

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.

53.3cm will be the focal length of converging lens.

What is 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.

A solid sphere of radius R, a solid cylinder of radius R, and a rod of length R all have the same mass, and all three are rotating with the same angular velocity The sphere is rotating around an axis through its center. The cylinder is rotating around its long axis, and the rod is rotating around an axis through its center but perpendicular to the rod. Which one has the greatest rotational kinetic energy? a. the sphere b. the cylinder c. the rod d. the rod and the cylinder have the same rotational kinetic energy e. they all have the same kinetic energy

Answers

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.
