Answer:
20 Ω
Explanation:
Voltage, current, and resistance are related by Ohm's law:
V = IR
40 V = (4 A) R
R = 10 Ω
The total resistance of the circuit is 10 Ω.
Resistors in parallel have a total resistance of:
1/R = 1/R₁ + 1/R₂
1 / (10 Ω) = 1 / (20 Ω) + 1/R₂
R₂ = 20 Ω
It would have to have a magnet on the other side
Energy of motion is the literal definition of kinetic energy
I believe the correct answer is false. <span>The parts of a mixture do not keep their own properties when they are combined. When they are combined, they exhibit or behave with different properties since each atom is bonded which gives them unique properties. Hope this helps.</span>

The Schwarzschild radius of an object of mass M is given by:
(1)
where
G is the gravitational constant
M is the mass of the object
c is the speed of light
The black hole in the problem has a mass of
where
is the solar mass. Substituting,
and substituting into eq.(1), we find the Schwarzschild radius of this black hole:
2) 242.8 solar radii
We are asked to find the radius of the black hole in units of the solar radius.
The solar radius is
Therefore, the Schwarzschild radius of the black hole in solar radius units is
