What is the principle of impulse-momentum?
What is the principle of impulse-momentum? The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. The impulse-momentum theorem is logically equivalent to Newton’s second law of motion (the force law). What is impulse principle? The Principle of Impulse and Momentum describes how an object’s linear and […]
What is difference between base load and peak load?
What is difference between base load and peak load? Base load is the level that it typically does not go below, that is, the basic amount of electricity that is always required. Peak load is the daily fluctuation of electricity use. It is usually lowest in the wee hours of the morning and highest in […]
Can you burn calories by laughing?
Can you burn calories by laughing? While you can’t just laugh your way to significant weight loss, the effect on our brain increases those feel good hormones and these in turn help us stick to our healthy eating plan. Research conducted by Vanderbilt University Medical Centre revealed that laughing for 10 to 15 minutes burns […]
What are the characteristics of malignant neoplasms?
What are the characteristics of malignant neoplasms? Thus, characteristics of malignant neoplasms include: More rapid increase in size. Less differentiation (or lack of differentiation, called anaplasia) Tendency to invade surrounding tissues. Ability to metastasize to distant tissues. What are the symptoms of neoplasia? Regardless of type, there are some common symptoms of neoplastic disease: anemia. […]
What is the difference between orientation and orbital?
What is the difference between orientation and orbital? Hence p orbitals have three orientations in space. Thus p orbital corresponds to dumb-belled shape with the atomic nucleus at its center. p orbitals have two lobes directed on opposite sides of the nucleus. P-orbitals are orientated in three different directions along X, Y and Z axis […]
What are precise numbers?
What are precise numbers? In mathematics, precision describes the level of exactness in a number’s digits, such as number 54.6 having precision 1 (one decimal digit). A number with end zeroes (“00”) has a negative precision, such as 500 having precision -2, or 4,000 as precision -3. A whole number (not ending in “0”) has […]
Where is the highest electronegativity found?
Where is the highest electronegativity found? Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative. What are the three most electronegative elements? And those three elements are fluorine, oxygen, and nitrogen. And in […]
What is the amount of carbon present in low carbon steel?
What is the amount of carbon present in low carbon steel? Low carbon steels have a carbon content of 0.10% to 0.30%. High carbon steel has 0.70% to 2.2% carbon. 3. A large amount of sulphur is present in the steel. What are the properties of low carbon steel? Low carbon steel contains approximately 0.05–0.15% […]
Why does hydrogen form at the cathode instead of sodium?
Why does hydrogen form at the cathode instead of sodium? When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms. However, sodium is too reactive for this to happen so hydrogen […]
