Answer: radio waves dont need a medium to travel through
Explanation:
Answer:
Option E is correction. None of the above.
Explanation:
( 1 ) A 3p orbital has more energy than 2p orbital and this is the reason it is away from the nucleus as compare to 2p orbital. Energy of the shells increases as their distance increases from the nucleus.
(2) p subshells are made up of three dumbbell-shaped orbitals
(3) There are three atomic orbitals in a p subshell. They are px, py, and pz.
1:1 is the ratio of the gravitational force that earth exerts on the sun in the winter and the force that it exerts in the summer because it is independent of temperature.
F=GMm/R²
Any action that aims to maintain, alter, or deform a body's motion is considered a force in mechanics. In his Principia Mathematica, Isaac Newton frequently used his three laws of motion to demonstrate the concept of force (1687).
According to Newton's first law, a body will remain in either its resting or equally moving condition along a straight path in the absence of an external force. The second law states that when an external force acts on a body, the body accelerates (changes velocity) in the direction of the force.

Those are some examples of physical changes happening around us
Answer:
There are three types of magnets: permanent magnets, temporary magnets, and electromagnets. Permanent magnets emit a magnetic field without the need for any external source of magnetism or electrical power.
The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core.
