What happens if 2 spiral galaxies collide? For example, two spiral galaxies can merge and form an elliptical galaxy. Galaxies are also composed of gas and dust. The gravitational pull of both colliding stars can interact with this materials, creating friction and shock waves that can ignite the formation of new stars. What will happen […]
Does lifting weights make you shorter?
Does lifting weights make you shorter? Most likely, the myth that lifting weights stunts growth came from concern over kids causing damage to their growth plates if they participate in a strength training program. But it’s not the result of lifting weights correctly. Can you grow taller after 30? Bottom line: Can height be increased? […]
Who is responsible for structure failure?
Who is responsible for structure failure? The most common causes of structural failures are: (1) Poor communication between the various design professionals involved, e.g. engineers involved in conceptual design and those involved in the supervision of execution of works. (2) poor communication between the fabricators and erectors. What are the causes of instability of steel […]
What is the difference between an air conditioner and a heat exchanger?
What is the difference between an air conditioner and a heat exchanger? With air conditioning, there is no concern about hot spots because cooling occurs at well below ambient temperatures. Heat exchangers effectively prevent hot spots even though the cooling is slightly above the ambient temperatures. What heat transfer mediums are utilized in a residential […]
What is the function of ribosome in protein synthesis?
What is the function of ribosome in protein synthesis? The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis. Is the translation between […]
What is an ideal weight?
What is an ideal weight? Body mass index (BMI) is a common tool for deciding whether a person has an appropriate body weight. It measures a person’s weight in relation to their height. According to the National Institutes of Health (NIH) : A BMI of less than 18.5 means that a person is underweight. A […]
What is amplitude Class 8 Definition?
What is amplitude Class 8 Definition? The maximum displacement of a vibrating object from its Central position is called the amplitude of vibration. The amplitude actually tell us how far the vibrating object is displaced from its central position. What is the amplitude of sound? The amplitude of a sound wave is the measure of […]
What are five differences between plant and animal cells?
What are five differences between plant and animal cells? A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds […]
What is powered by steam?
What is powered by steam? In steam. Steam power constitutes an important power source for industrial society. Water is heated to steam in power plants, and the pressurized steam drives turbines that produce electrical current. The thermal energy of steam is thus converted to mechanical energy, which in turn is converted into… How fast did […]
