El limon es conductor de electricidad?
JulijaS [17]

Answer:

Lo que sucede es que el electrolito (el jugo del cítrico) combinado con el zinc y el cobre, hace de batería, la cual a su vez completa un circuito eléctrico. Los cítricos, como las naranjas y los limones, son excelentes conductores de electricidad. ... También la patata es un buen conductor eléctrico.

A machine gear consists of 0.10 kg of iron and 0.16 kg of copper.
Natali5045456 [20]

Answer:

option (c)

Explanation:

mass of iron = 0.10 kg

mass of copper = 0.16 kg

rise in temperature, ΔT = 35°C

specific heat of iron = 450 J/kg°C

specific heat of copper = 390 J/kg°C

Heat by iron (H1) = mass of iron x specific heat of iron x ΔT

H1 = 0.10 x 450 x 35 = 1575 J

Heat by copper (H2) = mass of copper x specific heat of copper x ΔT

H1 = 0.16 x 390 x 35 = 2184 J

Total heat H = H1 + H2

H = 1575 + 2184 = 3759 J

by rounding off

H = 4000 J
