What is the importance of force? Forces are very important in all aspects of daily life: The force of up-thrust helps to keep objects floating. It is the example of action at a distance force. Gravity pulls us back down to earth (without touching us) when we jump up in the air. Is the force […]

Which is the best description of an alpha particle? Alpha particle, positively charged particle, identical to the nucleus of the helium-4 atom, spontaneously emitted by some radioactive substances, consisting of two protons and two neutrons bound together, thus having a mass of four units and a positive charge of two. What is the symbol of […]

Is height positive or negative? An object’s height is a property of that object and has nothing whatsoever to do with the object’s motion. It’s correct to speak of the object’s displacement when describing motion. “Negative height” is always a meaningless term. Without specifying a coordinate system, “negative displacement” is almost as useless. Can work […]

Do you drown slower in salt water? There is also a discrepancy between the time it takes to drown in the different liquids as well. The time it takes to drown in saltwater is between 5-30 minutes, while with fresh water, it only takes between 5-20 minutes. What happens if you drown in saltwater? “In […]

What is heterozygous a blood type? ABO Blood Types The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotype is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and […]

What is the atomic mass in an atom? The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of […]

What is the most powerful rocket in the world? Space Launch System What is the powerful thing on earth? Human Mind What is the strongest machine on earth? The Large Hadron Collider What is the most advanced machine on earth? Large Hadron Collider – facts about the most complex machine ever made. * Though built […]

What is the difference between a circuit breaker and a motor circuit protector? Based on what I know, MCP is only used for short circuit protection and Circuit breaker is used for overload as well as short circuit protection. What does a contactor do in a circuit? A contactor is a special type of relay […]

What is Newton equation of motion? Newton’s second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics. Is position the same as […]

Which of the following is an example of motion? In which of the following examples of motion, can the body be considered approximately a point object : (a) a railway carriage moving without jerks between two stations. (b) a monkey sitting on top of a man cycling smoothly on a circular track. (c) a spinning […]
