The sound wave will rebound when it is a barrier, hope this helps
goblinko [34]3 years ago

Answer: A barrier

Explanation: A sound wave requires medium to travel. It travels in air. Frequency is the number of cycles per second of a wave. A light is an electromagnetic wave which can travel through vacuum as well as medium. A sound rebounds when it encounters a barrier i.e. when it does not carry enough energy to travel through it.

Hence, the correct answer is a barrier.

A high power line carries a current of 1.0 kA. What is the strength of the magnetic field this line produces at the ground, 10 m
solmaris [256]

Answer:

The strength of the magnetic field that the line produces is 2x10^{-5} Tesla.

Explanation:

From Biot-Savart law, the equation to determine the strength of the magnetic field for any straight wire can be deduced:

           

B = \frac{\mu_{0}I}{2\pi r} (1)      

                                     

Where \mu_{0} is the permiability constant, I is the current and r is the distance from the wire.    

             

Notice that it is necessary to express the current, I, from kiloampere to ampere.

I = 1.0kA \cdot \frac{1000A}{1kA} ⇒ 1000A

Finally, equation 1 can be used:

B = \frac{(4\pi x10^{-7}T.m/A)(1000A)}{2\pi (10m)}    

           

B = 2x10^{-5}T    

Hence, the strength of the magnetic field that the line produces is 2x10^{-5} Tesla.

A ball bounces on the ground. How do the ball and the ground act on each other?(1 point)
liubo4ka [24]

Explanation:

It should be A because the when the ball bounces on the ground the ground will give it force to bounce again but also it wont go as high as it first did. Hope this helps:))

What is the difference between beta plus and minus
Minchanka [31]
Beta decay is very complex phenomena in natural radioactive decay. There are 3 types of Beta decay.

B+ decay (Beta plus or Beta positive or positron decay):

is the conversion of a proton into a neutron plus a positron and an electron neutrino.

B- decay (Beta negative or Beta nought):

is the conversion  of a neutron into a proton plus an electron and a electron antineutrino. 

Note: a positron is the a positive electron or the antiparticle of the electron.

Hope it helps
