Indique a sequencia de transformações energéticas no processo de aquecimento considerado a partir do gerador elétrico solar a) Solar-Mecânica-Elétrica b)Solar-Nuclear-elétrica c)Solar-quimica-quimica d)Solar-Elétrica-térmica

the answer is the first option

explanation:

just googled it m8. not that hard

lol

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
