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
<span>c =3.8* 10^{8} m/s
</span>
<span>c=λ*f
</span>⇒ λ= \frac{c}{f}
⇒ λ= \frac{3.8* 10^{8}}{9.4* 10^{9}}
⇒ <span>λ</span>=0.04 m

During which phase of mitosis do the nuclear membrane, nucleolus, and nucleus dissolve? metaphase prophase anaphase telophase
Mekhanik [1.2K]
Prophase 
During the prophase stage of mitosis, the nucleus seems to disband itself. The nucleolus suspends itself and finally, the nuclear membrane disassembles itself. This is because of the undergoing process of copying and dividing. 
Mitosis is a functional cell dividing process that helps the cells repair or rejuvenate itself because of apoptosis and other factors.

SCORPION-xisa [38]
The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.

The process by why subliminal stimuli act upon the unconscious mind, influencing behavior is called _________________ __________
Nataliya [291]

Answer:

subliminal perception.

Explanation:

Subliminal perceptions, also known as subliminal messages, are messages, either visual or auditory, that are presented just beyond the threshold of human perception. A subliminal perception may not be audible enough that the conscious mind might register it but be audible enough for the subconscious mind.

For example it might be an image transmitted briefly and unperceived consciously and yet perceived unconsciously.
