A6 kg object falls 10 m. the object is attached mechanically to a paddle-wheel which rotates as the object falls. the paddle-wheel is immersed in 600 g of water at 15°c. what is the maximum temperature that the water could be increased to? is this a very efficient way of heating water? the specific heat of water is 4.186 j/(g* ˚c).

Explanation:

Given

Mass of object (m)=6 kg

falling height(h)=10 m

mass of water()=600 gm

temperature of water =15

specific heat of water

Let T be the Final Temperature of water

Here Object Potential Energy is converted into Heat energy which will be absorbed by water

Potential Energy(P.E.)

Heat supplied

T-16=0.234

This is not an efficient way of heating water as there is onlyincrease in temperature.

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
