What is the main function of an ignition safety switch?

1 answer:

6 0

The function of an ignition safety switch is that it allows the engine of the vehicle to shut off or to be turned off immediately as it is to prevent further complications to happen as this is being used when an emergency is launched and to prevent further complications to happen to the engine that will be of best to the vehicle and to the people residing in it.

Calculate the amount of work done if you use a 100 N force to push a 50 kg box 5 m across the kitchen floor.

gogolik [260]

Work = force * distance
force = 100 N
Distance = 5m
work =100 N* 5m
=500 J

Study the motion map shown. what do the circled vectors represent?

BabaBlast [244]

Answer:

It's option d - Negative acceleration

Explanation:

Let's start by demonstrate why it's not option b - Speed : Speed is a scalar quantity so it can not be represented by a vector

Let's check that the green vectors represent velocity (velocity is a vector quantity, velocity is a direction aware, while speed is just a scalar)

Now let's show that the circled vectors are acceleration vectors:

Mathematically position X , velocity V and acceleration A are:

$\frac{dX}{dt} = V$ and $\frac{dV}{dt} = A$

Where X, V, A are vectors and $\frac{d(a)}{dt} = b$ indicates the derivate a of a time is equal to b.

So, this show that acceleration is a rate respect of time of velocity ⇒ When acceleration is positive, velocity increments, when acceleration is negative, velocity decrements.

The above explanation correspond to the motion map shown, getting demonstrated that the answer is D - Negative acceleration

Two 800 cm^3 containers hold identical amounts of a monatomic gas at 20Â°C. Container A is rigid. Container B has a 100 cm^2 pis

Vikki [24]

Answer:

1) Final Temperature of the gas in A will be GREATER than the temperature in B

2) Diagram of both processes on a single PV has been uploaded below

3) The Initial pressures in containers A and B is 3039.87 J/liters

4) the final volume of container B is 923.36 cm³

Explanation:

Given that;

Temperature = 20°C = 293 K

mass of piston = 10 kg

Area = 100cm³

Volume V = 800 cm³ = 0.8 L

ideal gas constant R = 8.3 J/K·mol

Final Temperature of the gas in A will b GREATER than the temperature in B

Diagram of both processes on a single PV has been uploaded below,

Initial pressures in containers A and B

PV = nRT

P = RT/V

we substitute

P = (8.3 × 293) / 0.8

P = 2431.9 / 0.8

P = 3039.87 J/liters

Therefore, The Initial pressures in containers A and B is 3039.87 J/liters

Given that;

power = 25 W

time t = 15s

the final volume of container B = ?

we know that;

work done = power × time

work done = 25 × 15 = 375

Also work done = P( V₂ - V₁ )

so we substitute

375 = 3039.87 ( V₂ - 0.8 )

( V₂ - 0.8 ) = 375 / 3039.87

V₂ - 0.8 = 0.12336

V₂ = 0.12336 + 0.8

V₂ = 0.92336 Litres

V₂ = 923.36 cm³

Therefore, the final volume of container B is 923.36 cm³
