Answer:
The answer is "Option d".
Explanation:
In the given scenario, when a surface is drawn in a magnetic field, the number of magnetic field lines that enter a surface must be equal to the number left because we know that magnetic field lines are always a closed curve hence the number of magnetic field lines that join the surface should match the total left.
In the first law of thermodynamics, the Q stands for heat.
delta E is the change in internal energy of a closed system is equal to the amount of heat (Q) in the system minus the amount of work done (W).
Answer:
The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high-energy gamma rays. The electromagnetic spectrum is traditionally divided into regions of radio waves, microwaves, infrared radiation, visible light, ultraviolet rays, x rays, and gamma rays.
Explanation:Exploration of the electromagnetic spectrum quickly resulted practical advances. German physicist Henrich Rudolph Hertz regarded Maxwell's equations as a path to a "kingdom" or "great domain" of electromagnetic waves. Based on this insight, in 1888, Hertz demonstrated the existence of radio waves. A decade later, Wilhelm Röent gen's discovery of high-energy electromagnetic radiation in the form of x rays quickly found practical medical use.This was on my notes
When the earth is directly between the Moon and the Sun, a Neap tide will happen along a shoreline that is facing the Sun.
In Neap tide moon is at closest distance to earth. The movement of moon cause sea storm/ tides by turbulence of waves.
Explanation:
O + 6V = 9V, so O = 3V
P = 9V as it is parallel to the 9V power supply.
