True, RR Lyrae stars pulsate, but with shorter periods and lower luminosities than Cepheids.
The pulsation periods of the fundamental-mode RR Lyrae stars range from about 0.3 to 1.0 days (Population II pulsators with longer periods are categorized as type II Cepheids), but the vast majority of them have generations longer than 0.45 days.
<h3>Why do RR Lyrae stars pulsate?</h3>
RR Lyrae stars pulse like Cepheid variables, but the nature and histories of these stars is thought to be rather different. Like all variables on the Cepheid fluctuation strip, pulsations are caused by the κ-mechanism, when the ambiguity of ionised helium varies with its temperature.

Answer:
The statement in Python is:
print("The average pH of citrus fruits is ",avg_citrus_pH)
Java
System.out.print("The average pH of citrus fruits is "+avg_citrus_pH);
C++
cout<<"The average pH of citrus fruits is "<<avg_citrus_pH;
Explanation:
The programming language is not stated; so, I answered the question in 3 languages (Python, Java and C++)
Assume that avg_citrus_pH has been declared and initialized; all you need to do is invoke a print statement and then append the variable
In Python, use print()
In c++, use cout<<
In Java, use System.out.print()
So, the statements are:
Python:
print("The average pH of citrus fruits is ",avg_citrus_pH)
Java
System.out.print("The average pH of citrus fruits is "+avg_citrus_pH);
C++
cout<<"The average pH of citrus fruits is "<<avg_citrus_pH;
The three items that can be enhanced due to the embedded computer technology are
Digital cameras
Smart phones
Home appliances
There is a massive list of items that are enhanced due to embedded computer technology. They range from simple systems like calculators, digital cameras, mobile phones, home appliances, to advanced systems like control nuclear power plant systems. All these items mentioned are always set to perform a particular function. They allow integration of various operating systems and are built to take advantage of miniature software or hardware state of electronic devices. Items such as smart phones have been enhanced and designed for power efficiency. They have taken advantage of embedded computing technology and do not come with heavy moving components like fans and huge processors. The same case applies to Digital cameras and Home appliance. Embedded computers in heavy equipment such as a washing machine cannot be compared to computing technology in a digital Panasonic camera.
