Identify 3 distractions for young drivers and explain how you plan to minimize these distractions
Veseljchak [2.6K]

Answer:

Phone, Eating, People in the car

Explanation:

your phone should always be off while driving and put away. Eating much like texting takes your attention away from the road so you should wait till you're parked or home to eat. People thrashing around or talking very loudly can be a terrible distraction. Ask them nicely to quiet down so you can focus on the road.

Maintain a distance of at least _____ between your vehicle and the vehicle behind you
Serga [27]

A

Maintain a distance of at least __2___ between your vehicle and the vehicle behind you.

Explanation:

As the car infront passes a stationary object like a lamp post, the driver in the car behind should count at least two- seconds before their car reached and passes the stationary object too. This two-second rule ensures that cars maintain a safe distance between each other to avoid tailgaiting and collisions.

This rule leaves at least some room for the drivers to react swiftly enough, and avoid collisions, in case the car infront holds emergency breaks. It is even recommended that more seconds are used in hazardous conditions such as fog and slippery roads.

A 179 ‑turn circular coil of radius 3.95 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicu
suter [353]

Answer:

The energy, that is dissipated in the resistor during this time interval is 153.6 mJ

Explanation:

Given;

number of turns, N = 179

radius of the circular coil, r = 3.95 cm = 0.0395 m

resistance, R = 10.1 Ω

time, t = 0.163 s

magnetic field strength, B = 0.573 T

Induced emf is given as;

emf= N\frac{d \phi}{dt}

where;

ΔФ is change in magnetic flux

ΔФ  = BA = B x πr²

ΔФ  = 0.573 x π(0.0395)² = 0.002809 T.m²

emf = N\frac{d \phi}{dt} = 179(\frac{0.002809}{0.163} ) = 3.0848 \ V

According to ohm's law;

V = IR

I = V / R

I = 3.0848 / 10.1

I = 0.3054 A

Energy = I²Rt

Energy = (0.3054)² x 10.1 x 0.163

Energy = 0.1536 J

Energy = 153.6 mJ

Therefore, the energy, that is dissipated in the resistor during this time interval is 153.6 mJ

tech A says that a Hall-effect sensor can be used in an electronic ignition system. Tech B says that an optical-type sensor can
Alex

Answer:

<em>Both Tech A and Tech B are correct.</em>

<em>Explanation:</em>

<em>The Hall effect sen sensor are used to control displacements and rotations of various body components  of the vehicles, engine vibrations , and the ignition   system</em>

<em>The  optical-type sensor converts rays of light  into electronic signals. It measures the quantity physically of which the translates to a form that is understandable or readable  by an instrument. An optical sensor is larger part of a  system that integrates light sources, a device for measuring  and the optical sensor, which therefore is usually  connected to an electrical trigger.</em>
