Un ilusionista de 60 kg se deja caer desde la cima de una plataforma de 20 m de altura. Ignore la resistencia del aire. Determine la energía cinética en el punto 2 (cuando la altura es de 15 m).

i. like it i'm gonna edit it tomorrow

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

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
