Answer: The electromagnetic waves reach Earth, while the mechanical waves do not.
Explanation:
Answer:
e. The net magnetic flux in this case would be equal to zero.
Explanation:
As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop
here we know that net magnetic flux is the scalar product of magnetic field vector and area vector
so here we have
= net magnetic flux
since we know that magnetic field always forms closed loop so if we find the integral over a closed loop
then in that case the value of the close integral must be zero
so correct answer would be
e. The net magnetic flux in this case would be equal to zero.
Answer:
Mg is the symbol for Magnesium. Atomic #- 12
Explanation:
Answer:
A) 588 pounds
Explanation:
According to the given conditions, we assume the beam to be simply supported at the ends carrying a uniformly distributed load of 125 pounds per feet and a point load of 600 pounds acting at 5 feet from the right support.
Referring the schematic:
<u>Moment about any point will be zero in equilibrium condition.
</u>
∴Take moment about point L

The amount of energy that a wave may transfer to a unit area of a surface each second is measured as the wave's intensity. Watts per square meter is a unit used to express intensity. A sound wave's frequency is equal to its rate of vibration, and its intensity is determined by its amplitude.
<h3>What is the intensity of sound waves affect the frequency?</h3>
The energy of a vibration is quantified in decibels as intensity or loudness (dB). A sound has a high intensity if it is loud.
Therefore, perceive noise as louder the higher the frequency, although frequency does not indicate how loud a sound is.
