What is a polymer coating? Polymer coatings are thin layers of polymer applied to either flat substrates or irregular objects. Polymeric coatings can be functional (adhesives, photographic films), protective (anticorrosion), or decorative (paint). They are also used to modify surfaces (paper coatings, hydrophobic coatings). Which polymer is used for protective coating? Epoxy polymers Is polymer […]

What is the process by which plants make food by converting solar energy into chemical energy?
What is the process by which plants make food by converting solar energy into chemical energy? Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. The glucose gives […]
What are the steps after a virus attaches to a host cell in the viral reproduction process?
What are the steps after a virus attaches to a host cell in the viral reproduction process? Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. What structure of a virus help it […]
Do shock absorbers support the weight of the vehicle?
Do shock absorbers support the weight of the vehicle? Despite what many people think, conventional shock absorbers do not support vehicle weight. Instead, the primary purpose of the shock absorber is to control spring and suspension movement. What is the purpose of a shock absorber? The role of the shock absorber is to keep the […]
What is the purpose of retainage?
What is the purpose of retainage? Retainage is the withholding of a portion of the funds that are due to a contractor or subcontractor until the construction project is finished.

What are the three members of the rule of three?
What are the three members of the rule of three? The Rule of Three [1] says that there are three member functions that go together: the destructor, the copy constructor, and the assignment operator. A class that defines a destructor should almost always define the other two members. Why do we use rule of three […]
