me into possible solutions to these complications. One solution could be to build dams to hold back the floodwaters. Another solution would be straightening rivers to increase the speed of the river to remove water from affected areas. Levees and embankments can prevent rivers from overflowing by increasing the height of the riverbanks to allow more water to be contained. Dredging can make a channel deeper‚ and free of sediment so it can contain more water. But these solutions have its disadvantages

after we have gone through fasting for a month from food and drinks starting from Subuh until Maghrib. There are three synonymous Eid’s day symbols for me which include wearing traditional clothes‚ making many types of traditional food and baking cookies.

constant speed of 2.0 m/s2 . (b) The elevator has a constant upward acceleration of 2.0 m/s2 . (c) The elevator has a constant downward acceleration of 2.0 m/s2 . (d) The cable snaps and the elevator falls freely (ignore friction and the bloody end!). SOLUTION: The weight of the person depends on Mass and g‚ therefore: W = M g = (70.0 kg) 9.80 m/s2 = 686 N downward in all cases (a)-(d). Using the free-body-diagram for the person is shown to the right‚ We solve for N (which equals to what the scale reads)

and population growth over the course of the past few centuries. Scientists are frenetically searching for the solution to this issue‚ and their outcomes are bleak. They are telling the world that if population growth does not slow‚ the earth will swell to a capacity too large to sustain itself and the conclusion will be apocalyptic. Explanations are numerous‚ however viable solutions are difficult to find. Adherents to the Malthusian theory‚ such as Garrett Hardin‚ author of the article There
