1. How does the structure of a hard-boiled egg compare to the crust, mantle, and core structure of Earth? What do the egg's laye

rs represent? What might the cracks represent?
2. How do Earth's layers compare in composition and properties with the egg's layers?

3. Can an egg be used as a satisfactory model for Earth's lithosphere (plates) and asthenosphere, plus the rest of the mantle, and the core? How? (Hint: Look very carefully under the shell could the membrane there represent the asthenosphere?)

4. Overall, is the cracked egg a useful model for Earth? Why or why not?

5. Unlike the eggshell sections, Earth's plates move relative to one another. A plate may move away from another plate, or it may move toward it. Earthquakes often result from interactions between plates. Predict what other consequences might result from plate motion.


6. Of the several possible non-egg models of Earth, which do you feel is most appropriate? Why?

7. Of the several possible nonegg models of Earth, which do you feel is least appropriate? Why?

Answer: for 1 and 2 The inside of the earth is layered something like an egg. Both have a thin, brittle shell. The crust of the earth is broken into pieces, like the cracked shell of a hard boiled egg. The mantle of the earth is like the egg white, and the core of the earth lies in the center, like the egg yolk.

for 3 the shell could also be used because you can crack

for 5 a few things that can happen in the result of plate motion there could be Mt formation or volcano formations.

Explanation:

I hope this helps :)

A 40 kg skateboarder runs at a constant velocity of 12 m/s and jumps off a stationary skateboard with a mass of 8 kg. What is th
horsena [70]

Answer:

60 m/s (in the opposite direction)

Explanation:

By conservation of momentum,

Initial momentum of board + Initial momentum of man = Final momentum of board + Final momentum of man

=> 0 + 40*12 = 8*(-v) + 0

=> v = -60 [ Negative indicates opposite direction ]

We divide the electromagnetic spectrum into six major categories of light. What are these 6 major categories
3241004551 [841]

Answer:

radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

Explanation:

Electromagnetic waves are the waves which are created as the result of the electrical waves which are perpendicular to each other and also perpendicular to the direction of propagation.

Electromagnetic spectrum is range of the frequencies and their respective wavelengths of the various type of the electromagnetic radiation.

In order of the increasing frequency and the photon energy and the decreasing wavelength the spectrum are:  

<u>radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. </u>

Two gliders move toward each other on a linear air track, which we assume is frictionless. Glider A has a mass of 0.50 kg, and g
Nataly_w [17]

Answer:

-0.4 m/s

-3.552 m/s

Explanation:

m_1 = Mass of first glider = 0.5 kg

m_2 = Mass of second glider = 0.3 kg

u_1 = Initial Velocity of first glider = 2 m/s

u_2 = Initial Velocity of second glider = -2 m/s

v_1 = Final Velocity of first glider

v_2 = Final Velocity of second glider = 2 m/s

As the linear momentum of the system is conserved we have

m_1u_1+m_2u_2=m_1v_1+m_2v_2\\\Rightarrow v_1=\dfrac{m_1u_1+m_2u_2-m_2v_2}{m_1}\\\Rightarrow v_1=\dfrac{0.5\times 2+0.3\times (-2)-0.3\times 2}{0.5}\\\Rightarrow v_1=-0.4\ m/s

The velocity of glider A is -0.4 m/s

u_1 = 0

u_2 = -5 m/s

v_2 = 0.92 m/s

m_1u_1+m_2u_2=m_1v_1+m_2v_2\\\Rightarrow v_1=\dfrac{m_1u_1+m_2u_2-m_2v_2}{m_1}\\\Rightarrow v_1=\dfrac{0.5\times 0+0.3\times (-5)-0.3\times 0.92}{0.5}\\\Rightarrow v_1=-3.552\ m/s

The velocity of glider A is -3.552 m/s

A stunt-rider on a motorcycle rides down a ramp and into a vertical loop-the-loop. If the diameter of the loop is 7.50 m, then t
VikaD [51]

Answer:

v = 6.06 m/s

Explanation:

In order for the rider to pass the top of the loop without falling, his weight must be equal to the centripetal force:

Centripetal Force = Weight \\\frac{mv^2}{r} = mg\\\\\frac{v^2}{r} = g\\\\v = \sqrt{gr}

where,

v = minimum speed of motorcycle at top of the loop = ?

g = acceleration due to gravity = 9.8 m/s²

r = radius of the loop = diameter/2 = 7.5 m/2 = 3.75 m

Therefore, using these values in equation, we get:

v = \sqrt{(9.8\ m/s^2)(3.75\ m)}

<u>v = 6.06 m/s</u>

A boy 1m tall looks at the swimming pool, which appears to be 75 cm deep, according to the people around him. He finds himself a
Leto [7]
When you look vertically downwards into a swimming pool full of water the bottom of the pool seems closer to you than it really is. The apparent depth at this point can be worked out using the formula:

Apparent depth = Real depth/Refractive index of water

However as you look towards the end of the pool the bottom seems to curve upwards – we are thinking about a pool of constant depth to start with.


If the depth of the pool really does change then the situation becomes more complex and you would need to allow for that when drawing the diagram
