The following scenarios are pertinent to driving conditions that one may encounter. See the following rules of driving.

<h3>What do you do when the car is forced into the guardrail?</h3>

Best response:

I'll keep my hands on the wheel and slow down gradually.
The reason I keep my hands on the steering wheel is to avoid losing control.
This will allow me to slowly back away from the guard rail.
The next phase is to gradually return to the fast lane.
Slamming on the brakes at this moment would result in a collision with the car behind.

Scenario 2: When driving on a wet road and the car begins to slide

Best response:

It is not advised to accelerate.
Pumping the brakes is not recommended.
Even lightly depressing and holding down the brake pedal is not recommended.
The best thing to do is take one foot off the gas pedal.
There should be no severe twists at this time.

Scenario 3: When you are in slow traffic and you hear the siren of an ambulance behind

Best response:

The best thing to do at this moment is to go to the right side of the lane and come to a complete stop.
This helps to keep the patient in the ambulance alive.
It also provide a clear path for the ambulance.
Moving to the left is NOT recommended.
This will exacerbate the situation. If there is no place to park on the right shoulder of the road, it is preferable to stay in the lane.

Consider the base plate of an 800-W household iron with a thickness of L = 0.6 cm, base area of A =160 cm2, and thermal conducti

ratelena [41]

Given-

Power, P = 800W

Thickness, L = 0.6cm

Area, A = 160cm²

Thermal conductivity, k = 60W/mK

The heat conduction would be

$\frac{d^2T}{dx^2} + \frac{d^2T}{dy^2} + \frac{d^2T}{dz^2} + \frac{e(gen)}{k} = \frac{1}{\alpha } \frac{dT}{dt}$

Except $\frac{d^2T}{dx^2}$ all the values are 0.

Therefore,

$\frac{d^2T}{dx^2} = 0$

Thus, the boundary conditions here would be

1. $Q_x_=_0 = -kA \frac{dT (0)}{dx} = Q_o$

2. $T(L) = T_L$

If a pendulum is 10m long, (a) what is the natural frequency and the period of vibration on the earth, where the free-fall accel

suter [353]

Answer:

(a) Natural frequency = 0.99 rad/sec (b) 0.4086 rad/sec

Explanation:

We have given length of pendulum = 10 m

(a) Acceleration due to gravity $=9.81m/sec^2$

Time period of pendulum is given by $T=2\pi\sqrt{\frac{L}{g}}$ , L is length of pendulum and g is acceleration due to gravity

So $T=2\pi\sqrt{\frac{L}{g}}=2\times 3.14\times \sqrt{\frac{10}{9.81}}=6.34sec$

Natural frequency is given by $\omega =\frac{2\pi }{T}=\frac{2\times 3.14}{6.34}=0.99rad/sec$

(b) In this case acceleration due to gravity $g=1.67m/sec^2$

So time period $T=2\pi\sqrt{\frac{L}{g}}=2\times 3.14\times \sqrt{\frac{10}{1.67}}=15.3674sec\$

Natural frequency $\omega =\frac{2\pi }{T}=\frac{2\times 3.14}{15.36}=0.4086rad/sec$
