32. Which type of electromagnetic wave is used for nuclear power and medical treatment?
adelina 88 [10]

Answer:

Answers at the bottom!!

Explanation:

For the first answer: Gamma ray

Gamma rays and x-rays consist of high-energy waves that can travel great distances at the speed of light and generally have a great ability to penetrate other materials. For that reason, gamma rays (such as from cobalt-60) are often used in medical applications to treat cancer and sterilize medical instruments.

For the second answer: They both have technological uses.

In my opinion I'm pretty sure it's A because we do use microwaves and x-rays as technological uses.

Hope this helps!!

Una pelota recorre 20 m hacia la derecha y luego 10 m hacia la izquierda, todo en un lapso de tiempo de 10 s , cual es si veloci
zvonat [6]

Answer:

v = 1  i ^ m / s,   v = 1 m / s

Explanation:

In this problem we show the difference between vectors and scalars.

The average speed is

          v = Δx / Δt

The bold are vectors            

          Δx = 20-10 = 10 i^  m

           v = 10/10

           v = 1  i ^ m / s

the unit vector indicates that the velocity is on the x-axis

The average speed is

           v =Δx / Δt

           v = 10/10

           v = 1 m / s

in this case we have a scalar

satela [25.4K]

Answer:

Option B

Explanation:

The phase difference is found by subtracting the 2.3m for the receiver from the other speaker which is 2.9m hence

Phase difference= 2.9-2.3= 0.6
