How are gamma rays and microwaves similar
1 answer:
They are both electromagnetic waves
Explanation:
Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields. The fields oscillate in a plane perpendicular to the direction of motion the wave, so they are transverse waves.
Electromagnetic waves are the only type of waves able to travel in a vacuum. All electromagnetic waves travel in a vacuum at the same speed, known as the speed of light, equal to:
Electromagnetic waves are divided into 7 different types, depending on their wavelength and frequency. From the shortest to the longest wavelength (and so, from highest to lowest frequency, since frequency is inversely proportional to wavelength), we have:
Gamma rays
X rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
So as we can see, both gamma rays and microwaves are types of electromagnetic waves. The difference between them is their different wavelength/frequency: in fact, the wavelength of gamma rays is extremently short (), while microwaves have longer wavelengths (at the order of the centimeter).

Answer:
The acceleration of the centre of mass of spool A is equal to the magnitude of the acceleration of the centre of mass of spool B.
Explanation:
From the image attached, the description from the complete question shows that the two spools are of equal masses (same weight due to same acceleration due to gravity), have the same inextensible wire with negligible mass is attached to both of them over a frictionless pulley; meaning that the tension in the wire is the same on both ends.
And for the acceleration of both spools, we mention the net force.
The net force acting on a body accelerates the body in the same direction as that in which the resultant is applied.
For this system, the net force on either spool is exactly the same in magnitude because the net force is a difference between the only two forces acting on the spools; the tension in the wire and their similar respective weights.
With the net force and mass, for each spool equal, from
ΣF = ma, we get that a = ΣF/m
Meaning that the acceleration of the identical spools is equal also.
Hope this Helps!
