Explanation:
Given that,
Wavelength = 6.0 nm
de Broglie wavelength = 6.0 nm

Answer:
500 Joules
Explanation:
W(work)= force * distance
w = 100*5
W= 500
Conservation and Rain Water Tank. Through conservation, they can save water in their own houses by lessening the use of water in an unimportant purpose; they can turn of the faucet when it is not used; they can use their laundry water to clean the bathroom and there are more. Through Rain Water Tank, they can create this structure in order to collect rain water and store it in the tank then use it afterwards such as in watering the plants.
