Answer:
Frictional force is produced when two bodies are rubbed against each other. It is the force that oppose the motion and therefore it stops or slow down a moving body.It depends upon the roughness or smoothness of the surface of the body in contact.Rough surface have more friction that the smooth surface. Similarly, the heavier body produces more friction than a lighter body. Frictional force acts in the opposite direction of the motion of the body.
Its A The paper clip is repelled away from the nail because an electromagnetic field magnetized to the nail
When four atomic orbitals are mixed to form hybrid orbitals, 4 x sp3
hybrid orbitals are formed.
<span>Carbon's 2s and all three of its 3p </span>orbitals<span> hybridize to form four sp</span>3 orbitals. These orbitals<span> then bond with four hydrogen atoms through sp</span>3-s <span>orbital </span>overlap, creating methane.
The voltage released because the charges in the current dropped electric potential energy; this energy loss occured due to the resistance of the metal strips.
<u>Explanation:</u>
- Current flows from huge voltage (high potential) to base voltage (low potential).
- So the end of the strip wherever the current goes at a higher voltage than the end of the strip where the current leaves.
- The voltage released because the charges in the current dropped electric potential energy; this energy loss occured due to the resistance of the metal strips.
- The electric potential energy converted into thermal energy, heating the strips.
