To be able to answer this item, we are to calculate the power that the machine could deliver from hp to kW.
(45 hp)(746 W/1 hp) = 33570 W
Power is the amount of energy delivered at a certain period.
t = (6.20 x 10^2 J)/ (33570 kJ/s)
t = 0.01845 s
Answer: Option (a) is the correct answer.
Explanation:
Global Positioning Systems (GPS) is a system which uses a network of satellites to construct maps. So, that it would be easy to trace location of a person, or to reach over a certain place.
It helps an individual by showing the route of destination wherever he/she wants to reach along with the total time to reach over the place.
Thus, GPS can determine the elevation of a given area and also it can determine latitude and longitude of a given area. As each GPS satellite broadcasts with a high power, narrow bandwidth, down link signal which can be received by our small hand held receiver antenna called mobile phone.
A GPS cannot determine the composition of soil on mountain ranges.
Thus, we can conclude that out of the given options, GPS can determine the composition of soil on mountain ranges is not true about the Global Positioning Systems (GPS).
It is like that, except most nails are steel or stainless steel, slowing to rusting process to about 5 years.
