Using the idea of work done under gravity, the height of the building is 187 m.
<h3>Work done in a gravitational field</h3>
We must recall that the work done in a gravitational field is given by; mgh
m= mass
g = acceleration due to gravity
h = height
mass = 60.0 kg
Workdone = 1.15x10^5 J
W = mgh
h = W/mg
h = 1.15x10^5 J/60.0 kg * 9.8 ms-2
h = 187 m

Answer:
C. Both A and B
Explanation:
<em>Electronic leveling systems: </em>These are automatic lifting jacks use for raising wheels and vehicle when parked or when work is to be done on the vehicle engine underneath or on wheels. unlike the manual jacks it is very quick and efficient.
Both technician right, for Technician A, a weight may be use during the procedure for balancing and leveling when raising, and for Technician B, the sensor in the electronic leveling systems is adjustable to adjust the height so as to maintain balancing and levelling.
Universe contains billions and billions of stars, galaxies, planets, asteroids, comets and many more different type of bodies. These objects emit radiations of varied frequency. In order to study these different kind of objects, different kind of technology is required. There are different type of missions: some contain probes which land on the surface, some orbit the bodies etc. These are for solar system. Yet some are space observatories having detectors to study light from distant objects. Further, there are different detectors for different wavelengths of electromagnetic spectrum.
The changing speed demonstrates the nearness of an increasing speed; this centripetal quickening is of enduring with significance and coordinated in any regard cases toward the hub of the pivot. This increasing speed is, thus, created by utilizing a centripetal anxiety that is furthermore reliable in significance and coordinated toward the hub of revolution. contained in regards to revolution around a settled hub of a firm build that is not irrelevantly little in contrast with the span of the course, each and every molecule of the constitution portrays a uniform around activity with the equivalent rakish speed, yet with speed and increasing speed different with the range with comprehend to the hub.
Answer:
Rectilinear propagation describes the tendency of electromagnetic waves to travel in a straight line. Light does not deviate when travelling through a homogeneous medium, which has the same refractive index throughout; otherwise, light suffers refraction.
