<h2>Answer: Diffraction</h2><h2 />

Diffraction is a characteristic phenomenon that occurs in all types of waves .

In this sense, diffraction happens when a wave (the light in this case) meets an obstacle or a slit .When this occurs, the light bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.

Note that the principal condition for the occurrence of this phenomena is that the obstacle must be comparable in size (similar size) to the size of the wavelength.

During an auto accident, the vehicle’s air bags deploy and slow down the passengers more gently than if they had hit the windshi

const2013 [10]

Answer:

0.381 m

Explanation:

Distance traveled S is found by

$S = ut + \frac{1}{2}a{t^2}$

Where S is distance traveled, u is initial velocity, t is time, a is acceleration

Since we acceleration a is given as 60g, where g is gravitational constant of 9.81 then a=60*9.81=588.6

The initial velocity u is zero hence ut=0

Substituting a with 588.6, t with 36 ms

$\begin{array}{c}\\S = 0 + \frac{1}{2}\left( {588.6 {\rm{m/}}{{\rm{s}}^2}} \right){\left( {\left( {36 {\rm{ms}}} \right)\left( {\frac{{1 {\rm{s}}}}{{{{10}^3} {\rm{ms}}}}} \right)} \right)^2}\\\\ = 0.3814128
{\rm{m}}\\\end{array}$

S=0.381 m

Three 5 Ohm resistors are connected in parallel to a 9 Volt power supply. What is the current through each resistor?

Sedaia [141]

Answer:

I₁ = I₂ = I₃ = 12 A

Explanation:

Since the resistors are connected in parallel across a battery. Hence, the voltage across each of them will be the same, which will be equal to the voltage of the power supply. Since each resistor has the same resistance of 5 Ω. Therefore. the current across each resistor will also be the same. We can easily calculate these current values by the use of Ohm's Law, as follows:

$V = IR\\I_{1}=I_{2}=I_{3}=\frac{V}{R} \\\\I_{1}=I_{2}=I_{3}=\frac{9\ Volt}{5 \Omega}\\\\$
