What is the kinetic energy formula? Kinetic energy formula KE = 0.5 * m * v² , where: m – mass, v – velocity. How do you find kinetic energy? In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an […]
How can you determine whether green or yellow is the dominant allele?
How can you determine whether green or yellow is the dominant allele? Since all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele. The green allele didn’t disappear; its effect is not seen in heterozygotes. Peas are yellow when they have either two yellow alleles . . […]
What property of substance is not affected by physical change?
What property of substance is not affected by physical change? A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. What are the physical properties of solution? It can be […]
What are the elements below and to the left of the zigzag line called?
What are the elements below and to the left of the zigzag line called? All of the transition elements are metals. Any element to the left of the zigzag line in the periodic table that runs from boron to astatine. All metals except mercury are solids at room temperature and pressure. What is the purpose […]
What household item can be used as a magnet?
What household item can be used as a magnet? Paper clips, scissors, screws, nuts, and bolts are just a few common everyday objects that are magnetic. A magnet will not attract paper, rubber, wood, or plastic. It is not true that a magnet will attract any kind of metal. What are 3 methods of making […]
What do dots mean in Lewis structure?
What do dots mean in Lewis structure? Lewis dot diagrams use dots arranged around the atomic symbol to represent the electrons in the outermost energy level of an atom. Single bonds are represented by a pair of dots or one line between atoms. Double bonds are represented by two pairs of dots or two lines […]
Does water with sugar freeze faster?
Does water with sugar freeze faster? Sugar lowers the freezing point of water, which makes frozen desserts fair game for changes in freezing point. Most desserts freeze between 29.5 to 26.6 degrees F (-1.4 to -3.0 C) depending on the concentration of sugar. At what temperature will sugar water freeze? Plain water freezes at 32 […]
Which biome has the most natural fires?
Which biome has the most natural fires? savanna biomes What are the two major climatic factors? The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much […]
Who defined work?
Who defined work? In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. What is the classic definition of work? Work is physical or mental […]
What force twists a material by turning the ends in opposite directions?
What force twists a material by turning the ends in opposite directions? Torsion forces twist a material by turning the ends in opposite directions. What is internal and external force? • Internal Forces: Forces which act on one part of an object. by another part of the same object. • External Forces: Forces which act […]
