Answer:
4)experiments with cathode ray tubes
Explanation:
when sufficiently high voltage is applied across the electrods, current starts flowing through a stream of particles moving in the tube the negative electrode (cathode) to the positive electrode (anode). These were called Cathode Rays or Cathode Ray Particles
Answer:
radiation
Explanation:
Based on the scenario being described in the question it can be said that the type of heat transfer that is being modeled is radiation. Like demonstrated in the picture attached below, radiation involved the transfer of heat through rays, waves, or particles as opposed to fluids or gases. Which is what is happening in this scenario, since the individuals are building up heat by moving and that heat is being passed on to the individuals around them through waves.

Answer:

Explanation:
Hello there!
In this case, according to the given chemical reaction, it is first necessary to compute the moles of reacting LiOH given its molar mass:

Thus, since there is a 1:1 mole ratio between lithium hydroxide and silver nitrate (169.87 g/mol) the resulting milligrams turn out to be:

Answer:
If the color of the light in the environment changes, then the number of light red kidney beans increases because the red light makes the light red kidney beans more difficult to see.
