A communications satellite transmits a radio wave at a frequency of 9.4 x 10^9 Hz. What is the signal’s wavelength? Assume the w

sergejj [24]

To calculate this we will use the light equation:
$c=$ λ $*f$

We have Frequency $f=9.4* 10^{9}Hz$ .
We know that speed of light in vacuum is $c =3.8* 10^{8} m/s$ .
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).

So:
$f=9.4* 10^{9}1/s$
 $c =3.8* 10^{8} m/s$

 $c=$ λ $*f$
⇒ λ $= \frac{c}{f}$
⇒ λ $= \frac{3.8* 10^{8}}{9.4* 10^{9}}$
⇒ λ $=0.04 m$

You have your .5 M sucrose solution. You need 1 L of a 50 mM solution. how much of the .5 M stock solution would you combine wit

Triss [41]

Answer: 100mL sucrose solution and 900mL water

Explanation: sucrose solution is 500 mM, i.e. 500mmol/L

water is 0mmol/L

To get 50mmol/L we need 1/10 L of sucrose solution = 100mL

and made up to 1L with water

An engineer is building a new steel skyscraper in a area with a lot of Earthquakes, Compare two systems (fixed based system and

Leokris [45]

Answer:

<h2>Base isolated system</h2>

Explanation:

Fixed based system:-

A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result.

Base isolated system:-

A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).

Hence,

A base isolated system is much more better in a area where there are a lot of earthquakes.

Where does fruit develop from? Is fruit unique to flowering plants?

Gelneren [198K]

Fruit comes from many different places it can grow on plants, just like apples grow on trees and it depends on what kind of fruit because some can grow of flowers like strawberries, figs, raspberries, and many more.
