A code of ethics is a set of principles and rules used by individuals and organizations to govern their decision making process, as well as to distinguish right from wrong. These codes are often more complex and contextual than simple morality, acknowledging specific situations and providing guidance. Many codes of ethics also specify penalties for violations. Professional and personal codes of ethics ensure that adherents are behaving in a socially acceptable manner. Organizations with an established code of ethics usually have review processes and appeal procedures in place to guard against malicious or self-serving use of the code.
You have a parallel circuit since it allows the electrons to travel in 2 paths, allowing the other light to stay lit.
force applied due to earth on the apple is given as

given that
m = 0.37 kg
a = 9.8 m/s^2
now we have


now as per Newton's III law equal and opposite force is applied on earth
so now we can find acceleration of Earth using same equation as we used above

here we know that
m = mass of earth
F = 3.63 N



so acceleration of earth is very small and given by above value
That would be called the Doppler Effect.
The Doppler effect is the change in the frequency and/or wavelength relative to the movement of the source of the wave You would notice this effect when you hear sirens. As they move away there is a sudden change in pitch. This was named after the physicist who noticed this phenomenon, Christian Doppler.
Radiation - it travels in all directions so when you place your hands above a fire radiation hits your hand and reveals to ur cells where they transfer that hear into electrical signals, making you feel heated
