Answer:
B. The crumple method, because the car absorbs all the forces that would otherwise act on the person.
Explanation:
The impact forces transmission to passengers needs to be minimized in order to achieve the highest safety level, hence in the case of a collision, car will crumple and absorb most part of that force and will not cause harmful sudden deceleration.
Main answer: 7.68
Supporting answer: Diffraction
Diffraction of light is the phenomenon where the bending of light happens around corners such that it spreads out and illuminates areas where the formation of shadow is expected.
The diffraction of light is divided into two types:
- Fresnel diffraction: Here the division of light is from a point source and incident and diffracted wavelengths are spherical
- Fraunhoffer diffraction: Here the division of light is from a point source or multiple source and incident and diffracted wavelengths are parallel.
Here diffraction grating, is defined as an optical element that divides the light into various wavelengths.
The formula for diffraction is: dsinФ=nλ
where, d is the distance between the slits, Ф is the diffracting angle, n is the order number and λ is the wavelength.
Given, grating is 2090 grooves per centimeter for n=1,
d=n/λ
Then,
Therefore,
dsinФ=nλ
sinФ=nλ/d
Ф=
Therefore, the red light appears at an angle of 7.68

A blue "H" means a center of high pressure (usually calm, sunny weather). A red "L" means low pressure (which can mean storminess). Most fronts extend from low-pressure centers.
