At depths of greater than 60 m, ice moves by plastic deformation. What causes this transition from brittle to ductile behavior?
mafiozo [28]

Answer:

Increase in the intensity of pressure allows very less deformation

Explanation:

For the water the variation of pressure at any depth is directly proportional to the depth of the water above that level.

Thus, at depth greater than 60 m the intensity of pressure on ice is very high and therefore very little deformation is possible.

Hence, the transition from brittle to ductile behavior is observed.

Why are nuclear power plants controversial
VashaNatasha [74]
I would have to say because while they do produce relatively clean power, it is extremely dangerous and overly harmful should one "melt down." Some people believe the reward is worth the risk, others do not. It is more a matter of perspective - are you near the nuclear power plant or not? If you are, chances are you won't like it - on the other hand, if you are not right hear the power plant you might like it more. I hope this helps!

P.S. - If you think I did a good job I would love it if you went to my YouTube channel to see if I can help you more there. I am just starting out and don't have much time to record, but I would love to have some user-submitted topics! Here is the link: https://www.youtube.com/channel/UCG0zQcSsxZ2mu-OnZRdI2-Q. I hope to see you there!

Solar cell A produces 100 joules of energy, when a light source is shown on it for 3 minutes. Solar cell B produces 200 joules o
ella [17]

Answer: (B). Solar cell B, because it generates more power.

Explanation:

Given that,

For solar cell A

Energy = 100 Joules

Time = 3 minutes = 180 sec

Power of cell A

Power = Energy/Time

P = \dfrac{100}{180}\ Watt

P = 0.55\ Watt

For solar cell B

Energy = 200 joules

Time = 5 minutes = 300 sec

Power of cell B

Power = Energy/Time

P = \dfrac{200}{300}\ watt

P = 0.66\ Watt

Hence, Solar cell B, because it generates more power.

How is wavelength related to the different colors we see in a rainbow?
olga55 [171]
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

You are sitting on the beach and wondering about the properties of mechanical waves. Describe them in terms of ocean waves.
Rudiy27

Answer:

The ocean waves is a mechanical wave that transmits mechanical energy in the wave by the synchronized and repeated oscillation of the waters about an equilibrium level such that as the wave approaches the shoreline, and the water depth decreases, the height of the wave also increases reflecting the effective transmission of energy while the medium which is the water through which the wave propagates, move back and forth within a small region

Explanation:

A mechanical wave like other waves is the oscillation of a field about an equilibrium level. In mechanical waves, the field consists of the oscillating matter such that the wave transmits energy through a medium. The displacement of the medium through which the wave energy is limited such that the wave energy is conserved to travel far.
