Atoms is basic particles ,electrons,neutrons and the Regions of the atom are called electron shells and contain the electrons. So “a neutral core surrounded by mostly empty space”sounds pretty sure to me :)

Describe how refraction concentrates wave energy so that some parts of a beach erode more.

Zigmanuir [339]

Refraction is the bending of the waves which is result of the fact that different parts of the wave reach the water with different speeds because of the angle approaching the shore.

<span>The wave refraction disperses the wave energy in quiet water areas and sand is deposited.<span> </span></span>

What transfers energy in the form of vibrating electric and magnetic fields?

Rashid [163]

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. ... The two vibrating fields together form an electromagnetic wave.

A solenoid of length 0.700 m having a circular cross-section of radius 5.00 cm stores 6.00 µJ of energy when a 0.400-A current r

Lorico [155]

Answer:

N/l = 104

Explanation:

Energy stored in the inductor is given by the formula

$U = \frac{1}{2}Li^2$

now we have

$6\times 10^{-6} = \frac{1}{2}L(0.400)^2$

now we have

$L = 7.5 \times 10^{-5}$

now we have

$L = \frac{\mu_0 N^2 \pi r^2}{l}$

$7.5 \times 10^{-5} = \frac{4\pi \times 10^{-7} N^2 \pi(0.05)^2}{0.7}$

$N = 73 turns$

now winding density is turns per unit length

$N/l = 104$

if an object is thrown directly upwards remains in the air for 5.6s before it returns to its original position, how long did it

Mila [183]

Okay so an object gets thrown upwards so the half way point of the trip would be the maximum height (before it starts coming back down). if the object stays in the air for a total of 5.6s, then that is the time it takes to go up and come back down. to find the time to maximum height, half the time of the whole trip

5.6s/2 = 2.8s
