A person lifts a 5.0 kg cement block a ver- tical distance of 1.2 m and then carries the
block horizontally a distance of 5.9 m.
The acceleration of gravity is 9.81 m/s2.
a) Determine the work done by the person
in the process.
Answer in units of J.
part 2 of 2
b) Determine the work done by the force of
gravity in the process.
Answer in units of J.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
