The velocity is 4374.45 m/s.
I got the answer by using v=d/t.
20,000meters / 25min= 4,374.45 m/s.
<span>The word that musicians use for </span>frequency<span> is </span>pitch<span>. The shorter the wavelength, the higher the </span>frequency<span>, and the higher the </span>pitch<span>, of the </span>sound<span>. In other words, short waves </span>sound<span> high; long waves </span>sound<span> low.</span>
Answer:
Sorry what is the question?
I would like to help you but I don't know where to begin please clarify
Explanation:
The magnitude of the electric field inside the picture tube is 998.476 kN/C.
<h3>What is an electric field?</h3>
It is an area in the space where a charged particle experiences a force. It can be calculated by the formula,

Where,
= electric field produced
= charge = 
= distance = 
= Coulomb's constant = 
Put the values in the formula,

Therefore, the magnitude of the electric field inside the picture tube is 998.476 kN/C.
