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 piano mover raises a 1000-n piano at a constant speed using a very light rope in a frictionless pulley system, as shown in the
Rina8888 [55]

Here As we can see the figure that the end of the rope is pulled by some force F

Now as we can see that Piano is connected by a pulley which is passing over the pulley so effectively net force on the piano upwards will be 2F as it is connected by 2 ropes by the pulley

Now for constant velocity of the piano we will say

2F - mg = ma

since velocity is constant so acceleration must be ZERO

so here we have

2F - mg = 0

as we know here that

mg = 1000 N

so we will have

2F - 1000 = 0

F = 500 N

so here force must be 500 N

An object moving with 108 km/h moves 400 m in 8 seconds. find the velocity attained by the object.
wlad13 [49]

Answer:50ms-1

Explanation:use the formula v=d/t

in order to find the velocity,devide the distance with time taken.

since distance is 400 meters devide it with seconds whiuch gives us 50.
