What is cathode ray tube?
The cathode ray tube determines the charge flowing in a gas. When an electric field is set up using metal electrodes, the cathode ray tends to bend towards the positive electrode.
This concludes that a charge and the electrodes present helps determine the charge of the beam of charged particle.
Thus, one of the main uses of this device is to test a beam of charged particles.

Answer:
S pole and S pole repelling
To determine the energy equivalent of an object, we use the famous equation of Einstein which is E=mc^2 where m is the mass of the object and c is the speed of light (3x10^8 m/s). We calculate as follows:
E = mc^2
E = 4.1 kg (3x10^8 m/s)^2
E = 3.69x10^17 J
Gamma rays
each section of the electromagnetic spectrum has characteristics energy level, wavelength and frequencies association with it's photons
Answer:
Liquid
Explanation:
Solids do not change shape, so we know it's not a solid.
Gases take the shape of their container, but they also expand to the volume of the container. The substance in this problem has the same volume in different size containers, so we know it's not a gas.
The substance must be a liquid. It takes the shape of its container but has a constant volume.
