Answer:
Potential Energy
Explanation:
Potential energy is the energy stored in an object due to it's position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Answer:
(b) Both are the same
Explanation:
When work is done to change a position or a state of motion, then the potential and kinetic energy are created. Then the energy gets transferred to an object. Its means the work is done.
The work done to change a position of an object is called potential energy while the work done to change a state of motion of an object is called kinetic energy.
We know that the total energy of a system remains constant. It is called the law of conservation of energy.
So, the work done is equal to the amount of PE or KE created. Hence, the correct option is (b).
That was his student, Johannes Kepler.
Answer:
<em>Rt = 8 ohm</em>
<em>I = 2 A</em>
<em>Vab = 12 V</em>
<em>VbΓ = 4 V</em>
<em>VaΓ = 16 V</em>
Explanation:
<u>Electric Circuits</u>
We'll apply Ohm's formula to solve the circuit shown on the image:
V = R.I
Where V is the voltage, R is the resistance, and I is the current.
The circuit has two resistances connected in series, thus the total resistance is:
Rt = R1 + R2 = 6 ohm + 2 ohm = 8 ohm
Now the current is:


I = 2 A
The voltages are calculated below:
Vab = R1 * I = 6 ohm * 2 A = 12 V
VbΓ = R2 * I = 2 ohm * 2 A = 4 V
VaΓ = Vab + VbΓ = 12 V + 4 V = 16 V
