1 answer:
Margaret [11]3 years ago
8 0

Answer:

Car pollutants, like exhausts, cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing <u>global warming, acid rain, and harming the environment and human health.</u> Engine noise and fuel spills also cause pollution.

The correct equation for the x component of a vector named A with an angle measured from the x axis would be which of the follow
Lady_Fox [76]

Answer:

Acosθ

Explanation:

The x-component of a vector is defined as :

Magnitude * cosine of the angle

Maginitude * cosθ

The magnitude is represented as A

Hence, horizontal, x - component of the vector is :

Acosθ

Furthermore,

The y-component is taken as the sin of the of the angle multiplied by the magnitude

Vertical, y component : Asinθ

Light from a laser strikes a diffraction grating that has 5500 lines per centimeter. The central and first-order maxima are sepa
WINSTONCH [101]

.Answer:

491.4 nm

Explanation:

The distance between central and first maxima is,

y=0.455m

And the distance between screen abnd grating is,

L=1.62 m

Now the angle can be find as,

tan\theta=\frac{y}{L} \\\theta=tan^{-1}(\frac{0.455}{1.62})  \\\theta=15.68^{\circ}

Now the grating distance is,

d=\frac{1}{5500} cm\\d=1.82\times 10^{-6}m

Now with m=1 condition will become,

\lambda=dsin\theta

So,

\lambda=1.82\times 10^{-6}m\times sin(15.68^{\circ})\\\lambda=1.82\times 10^{-6}m\times 0.270\\\lambda=491.4\times 10^{-9}m\\\lambda=491.4 nm

Therefore the wavelength of laser light is 491.4 nm.

A 920-kg sports car collides into the rear end of a 2300-kg SUV stopped at a red light. The bumpers lock, the brakes are locked,
GrogVix [38]

Answer:21.45 m/s

Explanation:

Given

Mass of sport car=920 kg

Mass of SUV=2300 kg

distance to which both car skid is 2.4 m

coefficient of friction (\mu)=0.8

Let u be the initial velocity of both car at the starting of skidding

and they finally come to zero velocity

v^2-u^2=2as

acceleration=\mu g=0.8\times 9.8=7.84 m/s^2

s=2.4 m

0-(u)^2=2\times (-7.84)\times 2.4

u=6.13 m/s

so before colliding sport car must be travelling at a speed of

920\times v=(920+2300)\times 6.13  (conserving momentum)

v=21.45 m/s
