Answer:
R + 6 ohms
Explanation:
The current is the same in all three resistors
i = 2 amps
The problem is that the total voltage is unknown.
R = r
R1 =3 ohms
R2 = 3 ohms
The voltage drop is E = I*R
I = 2 amps
R1 = 3 ohms
R1 = 3 ohms
E = 3*2 = 6 volts
The second 3 ohm resistor also has 6 volts across it.
The total is 12 volts so far. But we know nothing more on how to solve for R.
All you can say is that the total resistance = R + 6 ohms
Answer:
The diameter of the hole increases
Explanation:
Metals expand and contract with temperature. Whenever metal is heated, it usually expands in relation to its thermal expansivity. This expansion leads to a slight increase in surface area.
Once the surface area of the metal changes, this means that the dimensions of the whole metal surface changed. As a result, the diameter of the hole drilled in the metal plate will change also. In our case, the diameter of the hole will increase.
Answer:
c
Explanation:
kinetic energy is energy an object has due to its movement. for instance, if someone was riding down a hill, when the motion of the bike begins to decrease so does the kinetic energy
You do 1000 divide it by 10 which equals 100 W
The answer is Li2O.
Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides.
