Answer: B) Methyl alcohol requires less than half as much energy per kg to evaporate than water does
Explanation:
Latent heat of vaporization is the amount of heat required to convert 1 kilo gram of liquid into its vapor state without change in its temperature.
Heat of vaporization is more for water than for methyl alcohol which means more heat is required to convert from liquid to vapour form.
As the Heat of vaporization for methyl alcohol (1100) is almost half as that of Heat of vaporization for water (2257) , it means Methyl alcohol requires less than half as much energy per kg to evaporate than water does.
Answer:
Option (A)
Explanation:
The law of uniformitarianism describes how ripple marks were formed in the mountains.
This law says that the geological processes that occur extensively over the surface of the earth and configures the earth's surface in the present, have occurred in the past too and will also continue in the future.
This law simply describes that the present is the key to the past. This means that the processes that occur now must have taken place of the past.
In the given condition, this best describes the formation of ripples in the mountains.
Thus, the correct answer is option (A).
Answer:
a) Acceleration = 7.41 m/s^2
b) Distance ran = 6.75 m
Explanation:
For Acceleration use the formula...
a = (v - u) ÷ t....where v=10 and u=0....and t=1.35
a = (10 - 0)÷ 1.35
;acceleration = 7.41m/s^2
For the distance moved in 1.35s
;use the...s = ut + 1/2at^2....where s is the distance moved
;s = (0)(1.35) + 0.5(7.41 × 1.35^2)
Distance moved = 6.75m
Becomes older
Explanation:
As sea floor spreading occurs at divergent margins, the oceanic plate becomes older. Younger plate margin are the closest to the margin whereas the older plates bushes backward away from the spreading centers.
- The idea that the sea floor spreads was postulated by Harry Hess shortly after the second world war around the 1960's.
- At divergent margins new crust materials from the mantle are brought to the surface.
- They crystallize and settle at the flanks of plate margins.
- Older ones are pushed backward away from the margin into far away subduction zones.
