Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.

How do microwaves use the behavior and characteristics of the electromagnetic wave to function?
serg [7]

Answer:

Radiation moves out of the microwave into waves causing heat.

Explanation:

Inside your microwave oven, electrical energy is transformed into EM energy in the magnetron. When the microwave photons interact with food, food molecules are physically agitated, transforming the EM energy into kinetic energy, or energy of movement   .

Hope it helped!

A 12 kg barrel is pulled up by a rope. The barrel accelerates at 1.2 m/s2. Find the force exerted by the rope. Show all your wor
IgorLugansk [536]

Answer:

F = 132N

Explanation:

Let the pulling force be F

Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/sec^2

We know that Net Force = mass\times acceleration

Now net force = F - mg

F - mg = ma

F = mg + ma

F = m(a+g) = 12\times (1.2 +9.8)=132N  

Note that there will be a downward force acting on the body which is equal to mg
