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 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 […]

How does a catalyst decrease activation energy?
How does a catalyst decrease activation energy? A catalyst can lower the activation energy for a reaction by: orienting the reacting particles in such a way that successful collisions are more likely. reacting with the reactants to form an intermediate that requires lower energy to form the product. What is difference between positive and negative […]
What four factors affect the magnitude of the induced emf in a coil?
What four factors affect the magnitude of the induced emf in a coil? What four factors affect the induced emf? The induced e.m.f. is proportional to the number of turns in a coil. The speed at which the conductor moves through the magnetic field. The length of the conductor. The rate at which the conductor […]
What are multiple alleles give an example?
What are multiple alleles give an example? Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness. What […]

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 […]

What are the limitations of Einstein theory of specific heat?
What are the limitations of Einstein theory of specific heat? The correct statement is that Einstein’s law fails to account for the low temperature behavior of specific heat of solids, even qualitatively, but at high temperature it goes to the Dulong and Petit law limit, which is an accurate description of the specific heat of […]
