Convert the number from scientific into standard notation: 5.9 x 10-2
guapka [62]
Move the decimal point to:
Left : (if the exponent of ten is a negative number -) ... OUR CASE HERE (-2)
or to
Right : (if the exponent is positive +).

You should move the point as many times as the exponent indicates.
Do not write the power of ten anymore.

So, standard form is:
Two points to the left {Exponent of Ten is Negative (-2)}
0.059 ... (without the 10)

A 0.23-f capacitor is desired. What area must the plates have if they are to be separated by a 3.8-mm air gap?
tia_tia [17]

The area of the plates must have is(A)= 9.91×10⁷ m²

<h3 /><h3>How can we calculate the value of a area of a capacitor?</h3>

To calculate the the value of a area of the plates of a capacitor, we are using the formula,

C=\frac{\epsilon_0 A}{d}

Or, A= \frac{C\times d}{\epsilon_0}

Here we are given,

C= The desired capacitance of a capacitor.

= 0.23F

d=distance of separation between the plates.

=3.8mm= 0.0038m.

\epsilon_0= permittivity of the vacuum.  

=8.854×10⁻¹²F/m

We have to calculate the area of the plates must have = A m².

Now we put the known values in the above equation, we can get

A= \frac{C\times d}{\epsilon_0}

Or, A=\frac{0.23\times 0.0038}{8.854\times 10^{-12}}

Or, A= 9.91×10⁷ m²

From the above calculation, we can conclude that the area of the plates must have is(A)= 9.91×10⁷m²

To make the jump, Neo and Morpheus have pushed against their respective launch points with their legs applying a _____ to the la
Nimfa-mama [501]
Force is the interaction that changes the motion of an object. If we want to make a jump, our legs have to exert a force to the ground (or launch points), so that we can gain an equal and opposite force that changes our motion from being static on the ground to moving forward.

Demonstrate that plants use photosynthesis to grow throughout their lives
gavmur [86]
By definition, photosynthesis is the process made by green plants, algae and some other forms of bacteria to make their own food by converting carbon dioxide and water into glucose.

So how important is photosynthesis to plants? It is as important as how humans need food in order to survive. Plants also need food and energy to survive and grow. 

Not only food is the important matter to be addressed when it comes to photosynthesis. It is also important for plants' cellular respiration. These processes are constantly made by plants throughout their entire life.

Dawn and Timothy are sailboating in Lake Obewon. Starting from rest near the shore, they accelerate with a uniform acceleration
castortr0y [4]

Answer:

The value is s =63.18 \  m  

Explanation:

From the question we are told that

   The uniform  acceleration is   a =  0.39 \ m/s^2

   The time considered is t =  18 \  seconds

Generally the from kinematic equation we have that

          s =  ut + \frac{1}{2} at^2

Given that the boat started from rest , the initial velocity is  u =  0  m/s  

So

       s =  0 * 18 + \frac{1}{2} *0.39 * 18^2

=>      s =63.18 \  m
