Answer: Diffraction occurs when waves interact with a gap.

Diffraction occurs in any type of wave—mechanical or electromagnetic.

Explanation:

The phenomenon of light to bend around a small obstruction in its path is known as diffraction. Diffraction occurs for any type of waves- transverse or longitudinal i.e. for mechanical or electromagnetic waves.

When the medium changes- refraction occurs. Waves reflect back from a barrier. Diffraction occurs when the wavelength of the wave is comparable to the size of the gap. The wave bends around the corners of the gap.

h(t) = - 16t2 + 64t + 112 where t is the time in seconds. After how many seconds does the arrow reach it maximum height? Round t

laila [671]

Answer:

2 seconds

Explanation:

The function of height is given in form of time. For maximum height, we need to use the concept of maxima and minima of differentiation.

$h(t)=-16t^{2}+64t+112$

Differentiate with respect to t on both the sides, we get

$\frac{dh}{dt}=-32t+64$

For maxima and minima, put the value of dh / dt is equal to zero. we get

- 32 t + 64 = 0

t = 2 second

Thus, the arrow reaches at maximum height after 2 seconds.

Heating gas to create plasma can yield A) neutrons. B) elements. C) molecules. D) free electrons.

Romashka [77]

<h2>Answer: free electrons</h2>

Plasma is known as the 4th state of matter and is itself ionized gas. In this sense, ionization consists of the production of ions, which are electrically charged atoms or molecules due to the excess or lack of electrons with respect to a neutral atom or molecule.

That is why in this process there are always free electrons. Therefore in heating gas to create plasma can yield free electrons, and the correct option is D.

WITCHER [35]

Answer:

Explanation:

la frecuencia = ω/2π, nada cambio

v(max) = ωA → ω2Α = 2ωA duplicara velocidad máxima

a(max) = ω²Α → ω²2Α = 2ω²Α duplicara la aceleración máxima

la energía total ½kA² → ½k(2Α)² = 4(½kA²) cuatro veces la energía
