Answer:

There are 5 kingdoms

Explanation:

The scheme most often used currently divides all living organisms into five kingdoms: Moneran (bacteria), Protista, Fungi, Plantae, and Animalia. This coexisted with a scheme dividing life into two main divisions: the Prokaryote (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

Camera flashes charge a capacitor to high voltage by switching the current through an inductor on and off rapidly. In what time
Ber [7]

Answer:

The value is  \Delta  t = 4.0 *10^{-7} \  s

Explanation:

From the question we are told that

  The current is \Delta  I  = 0.100 \  A

  The  inductor  is L  =  2.0mH  =  2.0*10^{-3} \  H

  The voltage induced is  \epsilon   =  500 V

Generally the emf induced is mathematically represented as

      \epsilon =  L  *  \frac{\Delta I }{\Delta  t }

Here  \Delta  t is the time taken  

=>  \Delta  t =  \frac{L  * \Delta  I }{\epsilon }

=>  \Delta  t =  \frac{2*10^{-3}  * 0.100 }{500  }

=>  \Delta  t = 4.0 *10^{-7} \  s

max2010maxim [7]

Answer:

E. all of these

Explanation:

The designation of a point in space all the points that necessary

- reference point

- a direction

- fundamental units

- a direction

- motion

all are necessary to designate a point in space. Hence option E is correct.

For example in simple harmonic motion we need to specify all the above factors of the object in order to designate the position of the object.
