Answer:
the speed in -y
Explanation:
For this exercise we must use the right hand rule. The motion of a positive charge is given by.
Thumb points in the direction of speed
fingers extended in the direction of the magnetic field, + z axis
the palm in the direction of the force, as the charge is negative in the opposite direction of the force, axis + x
therefore the thumb is in the direction - y
the speed in -y
Answer:
Fan speed
Explanation:
because is the dependent variable
The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
EXPLANATION :
Before going to answer this question, first we have to know the electromagnetic spectrum.
Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.
When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -
Radio wave < Micro wave < Infrared wave < Visible light < U.V ray< X-ray < Gamma ray .
Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.
We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.
The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .
