How to square imaginary numbers

1 answer:

5 0

An imaginary number " i " is the squared root of -1, so whenever you square i it's like squaring a squared root. The squared root would cancel and you would be left with just the number under it, that is, the -1.
i ^ 2 = -1

<h2>Answer:</h2>

Driver experiences 17.68 G's on an average.

<h2>Step-by-step explanation:</h2>

In the question,

We know that in a car crash the speed of the car goes from the speed of 26 m/s to 0 m/s in 0.15 seconds.

So,

The final speed, v = 0 m/s

Initial speed, u = 26 m/s

Also,

Time in seconds, t = 0.15 s

So,

Using the equation of law of the motion, we get,

v = u + at

0 = 26 + a(0.15)

a = -26/0.15

a = -173.33 m/s²

As, there is deceleration of the car is taking place the acceleration is in negative.

Now,

To convert it into the force in the G's we need to divide the deceleration by the acceleration (gravity), g.

So,

G's experienced by the driver on an average is given by,

$\frac{173.33}{9.8}=17.68$

Therefore, on an average the driver experiences 17.68 G's.

Oduvanchick [21]

Answer:

No, This is not a valid Probability Distribution

Step-by-step explanation:

Probability [Neighbour walks with Beagle] = 20%

Probability [Neighbour walks with Golden Retriever] = 70%

Probability [Neighbour walks alone] = 30%

Disjoint Events are the events that have zero probability of occurring together. If all the three above items are disjoint, it means that it can never happen that two of them happen together.

The total (summed) probability of a valid probability distribution, with disjoint sets = 1 . In given case, total probability = 0.2 + 0.7 + 0.3 = 1.2 ; i.e > 1.

So, this probability distribution with stated disjoint events is not a Valid Probability distribution.
