A train travelling uniformly on the level at the rate of 80km/h begins ascent of 1 in 75. the tractive force that the engine exerts during the ascent is constant and equal to 1/100 of the weight of the train, the resistance (due to friction, etc) is constant, and equal to 1/150 of the weight of the whole train. Show that the train will come to a standstill after climbing for 2.5km

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

explain:

we don't have any choices.

An artesian well is simply a well that doesn't require a pump to bring water to the surface; this occurs when there is enough pressure in the aquifer. The pressure forces the water to the surface without any sort of assistance.

Hope it helps!
