<h2>Let us solve for it </h2>

Explanation:

In the given figure we need to find the total resistance and total voltage .

We know that :

  • In series total R =R1 +R2 ...
  • In parallel total R formula is : 1/R=1/R1 +1/R2.....
  • We also know ohm's formula is : V=IR

So, in this circuit : R1=12 ohm

R2=8 ohm

R3=10 ohm

Ammeter reading = 10A

so, they are in series therefore ,

Total R = R1 + R2 +R3

R=12 +10+8=30 ohm

To find voltage we have : V=IR

                                          V =10 x 30=300Volts

Explain archimedic principal with neat sketch ​
solniwko [45]

Answer:

Archimedes' principle states that: “The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid”.

The chemical equation below shows the formation of aluminum oxide (Al2O3) from aluminum (Al) and oxygen (O2).
Rufina [12.5K]

Answer:

Mass = 182.4 g

Explanation:

Given data:

Number of moles of Al₂O₃ = 3.80 mol

Mass of oxygen required = ?

Solution:

Chemical equation:

4Al + 3O₂    →       2Al₂O₃

Now we will compare the moles of aluminum oxide and oxygen.

                Al₂O₃           :           O₂

                   2               :            3

                 3.80            :         3/2×3.80 = 5.7

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 5.7 mol × 32 g/mol

Mass = 182.4 g
