The crumple zone help protect a passenger from injury by converting some of the kinetic energy possessed by the car into a controlled deformation, or crumpling when there is a crash.

<h3>What is impact?</h3>

The term impact refers to a large force that acts for a short time. Passengers in a vehicles sustain injuries after an accident due to the high impact of the crash.

As such, the crumple zone help protect a passenger from injury by converting some of the kinetic energy possessed by the car into a controlled deformation, or crumpling when there is a crash.

Delicious77 [7]

Answer:

The answer is "Speed".

Explanation:

In the question, the Speed is the correct answer because it can be viewed as its rate from, which a length is covered via an object. It is also divided by time into other components of distance. Its SI unit of speed seems to be the meter/second, but still, the kilometer/hour or, in the Us UK, miles per hour is the most basic fundamental of speed in everyday use.

In your research lab, a very thin, flat piece of glass with refractive index 1.20 and uniform thickness covers the opening of a

liraira [26]

Answer:

(a). The thickness of the glass is 868 nm.

(b). The wavelength is 3472 nm.

Explanation:

Given that,

Refractive index = 1.20

Wavelength = 496 nm

Next wavelength = 386 nm

We need to calculate the thickness of the glass

Using formula for constructive interference

$2nt=(m+\dfrac{1}{2})\lambda$

Put the value into the formula

In first case,

$2nt=(m+\dfrac{1}{2})496$ .....(I)

In second case,

$2nt=(m+1+\dfrac{1}{2})386$

$2nt=(m+\dfrac{3}{2})386$ .....(II)

From equation (I) and (II)

$(m+\dfrac{1}{2})496=(m+\dfrac{3}{2})386$

$110m=336$

$m=3.0$

Put the value of m in equation (I)

$2nt=(2+\dfrac{1}{2})496$

$t=\dfrac{(3+\dfrac{1}{2})496}{2\times1}$

$t=868\ nm$

The thickness of the glass is 868 nm.

(b). We need to calculate the wavelength

Using formula of constructive interference

$2nt=(m+\dfrac{1}{2})\lambda$

$\lambda=\dfrac{2nt}{(m+\dfrac{1}{2})}$

Put the value into the formula

$\lambda=\dfrac{2\times1\times868}{\dfrac{1}{2}}$

$\lambda=3472\ nm$

Hence, (a). The thickness of the glass is 868 nm.

(b). The wavelength is 3472 nm.

true or false:acceleration toward the center of a curved or circular path is called gravitational acceleration.

nalin [4]

Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.
