Place the object in an electronic balance and measure its mass.
Place a measured amount of water in the cylinder.
Place the object in the cylinder so that it’s fully submerged.
Measure the new level of the liquid and subtract the original level. This is equal to the volume of the object.
Density = mass / volume.
Answer:
A: 3 Mg, 2 P, 14 O, 12 H
Explanation:
I took the test on Edgenuity
Answer:
10 h
Explanation:
velocidade é a taxa de variação da distância no tempo. é a razão entre a distância e o tempo
de Santos e Curitiba:
distância (d) de 480 km, velocidade (s) de 80 km/h
de Curitiba e Florianópolis:
distância (d) de 300 km, velocidade (s) de 75 km/h
tempo médio de ônibus entre Santos e Florianópolis = 6h + 4h = 10h
Answer:
There may be excess charges in the interior of the wire
The net electric field everywhere inside the wire is zero
The interior of the metal wire is neutral.
There may be excess charges on the surface of the wire.
There is no net flow of mobile electrons inside the wire.
Explanation:
For any metal wire in equilibrium position, there may be excess charges in the interior of the wire and the net electric field everywhere inside the wire is zero. Additionally, the interior of the metal wire is always neutral and there is likely to be excess charges on the surface of the wire. Moreover, it's important to note that for a metal wire in equilibrium, there is no net flow of mobile electrons inside the wire.
