<span>When the delta brainwave frequencies increase into the frequency of theta brainwaves,
active dreaming takes place and often becomes more experiential to the
person. Typically, when this occurs there is rapid eye movement, which
is characteristic of active dreaming. This is called REM, and is a well
known phenomenon.. Hope that helps!</span>
The electric current<span> is the number of electrons or charges passing through a conductor per units of time. 1 ampere = 1 coulombs / 1 second. </span>Electric discharge <span>is the consequence of disrupting an isolator (for example, air), thus causing a sudden flow of </span><span>electricity</span>
Answer:
In a vacuum
Explanation:
Sound is a type of mechanical waves. Mechanical waves are waves that propagate through the oscillation of the particles in a medium, which can be either gas, liquid or solid.
A sound wave in air, for instance, is simply produced by the oscillations of the air particles back and forth along the direction of motion of the wave.
Given this definition, it is clear that mechanical waves (and so, sound waves as well) cannot be transmitted if there is no medium: therefore, they cannot be transmitted in a vacuum. So, the sound of the ringing bell would not be present in a vacuum.
Technically friction is acting on the car because it is still rubbing against the street and gravity is pulling the car down preventing it from floating??? lol
Answer:
<h2>B) Newton's 2nd law</h2>
Explanation:
<h2>From; force= mass × acceleration </h2><h2> f= m×a </h2><h2>where a(acceleration)= velocity/time</h2><h3> force = mv/t</h3><h3>But momentum(p) = Mass × velocity </h3><h2>hence force =p/t </h2><h3>that is Momentum = force × time ( Newton's 2nd law)</h3>
