Morning Your answer is A I had this question this morning and I got it correct so <em>I hope this helps!</em>
Nataly [62]3 years ago

Answer: Option (A) is the correct answer.

Explanation:

Heat from inside the surface is transferred to its surface through conduction. As in conduction, there is transfer of heat from hotter substance to colder substance when placed together.

Therefore, less dense material rises towards the surface by the process of convection and more denser (colder) material remains inside the Earth.

Thus, we can conclude that warmer material is pushed to the crust.

What would be the overall outcome of starting the procedures with cold water instead of room temperature water
miss Akunina [59]

Answer:

Electrolysis will be slowed.

Explanation:

Cold water is more dense and therefore it can slow down electrolysis process. Efficiency of electrolysis variate with change in temperature of water.The efficiency of electrolysis increases with increase in temperature of the water. If cold water is used then the process will be slowed down.

Responsible for weather patterns on earth is what convention, radiation, conduction?
tatuchka [14]

Answer:

Convection. Convection is the transfer of heat energy in a fluid. ... As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.

You've recently read about a chemical laser that generates a 20.0-cm-diameter, 22.0 MW laser beam. One day, after physics class,
Setler [38]

Answer:

0.3847 m/s

Explanation:

I = Intensity = \dfrac{P}{A}=\dfrac{P}{\pi r^2}

d = Diameter = 20 cm

r = Radius = \dfrac{d}{2}=\dfrac{20}{2}=10\ cm

c = Speed of light = 3\times 10^8\ m/s

s = Distance = 100 m

P = Power = 22 MW

Pressure due to the laser is given by

P_r=\dfrac{I}{c}\\\Rightarrow P_r=\dfrac{P}{Ac}\\\Rightarrow P_r=\dfrac{P}{\pi r^2c}\\\Rightarrow P_r=\dfrac{22\times 10^{6}}{\pi 0.1^2\times 3\times 10^8}\\\Rightarrow P_r=2.33427\ N/m^2

Force is given by

F=P_rA\\\Rightarrow F=2.33427\times \pi 0.1^2\\\Rightarrow F=0.07333\ N

Acceleration is given by

a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{0.07333}{99}\\\Rightarrow a=0.00074\ m/s^2

Speed of the block would be

v=\sqrt{2as}\\\Rightarrow v=\sqrt{2\times 0.00074\times 100}\\\Rightarrow v=0.3847\ m/s

The speed of the block is 0.3847 m/s
