What does it mean to say momentum is conserved?
What does it mean to say momentum is conserved?
What other physical quantities are quantized apart from charge?
Volume and mass or physical qualities related to weight and size of the actual specimen. Density, hardness, and molecular weight are physical qualities that are quantized based on the material.
If momentum were conserved the ratio of the total momentum after the collision to the total momentum before the collision would be?
1 +/- two decimal place
Are there different types of decibels?
Decibels (dB) mean a logarithmic unit of measurement that expresses the magnitude of a physical quantity relative to a specified or implied reference level. Since it expresses a ratio of two quantities with the same unit, it is a dimensionless unit. Decibel is Decibel!
What compares or shows the relationship of two quantities in science?
these type of quantities are called derived quantities. Their value depends on some fundamental quantities or some other derived quantities. eg. force is a derived quantity whose value depends on mass(fundamental) and acceleration(derived).
What are the two quantities are always conserved in nuclear decay equation?
Energy and electrical charge are two quantities that are always conserved in nuclear decay equation.
Types of physical quantities?
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
What quantities are conserved when balancing a nuclear reaction?
In order for a nuclear reaction to be balanced, there are quantities that must be conserved. The quantities are the atomic numbers and mass numbers of the particles involved in the reaction.
What two quantities are conserved in redox equations?
there is a conservation of mass and charge.
What is the ratio of two different physical quantities?
Rate
What is conserved when two object collide in a closed system?
Momentum is conserved when two objects collide in a closed system.
What is the two types of physical quantities?
Generally there are two types of physical quantities. One without direction known as scalars other with direction known as vectors. While there are other physical quantities as well that cannot be classified under the two above mentioned categories, they are tensors, matrices, spinors and quaternions.
Which physical quantity is conserved when a planet revolves around the sun?
moment of inertia is conserved.
What is conserved in physical changes?
Mass and energy
What are theclassifications of physical quantities according to magnitude and direction?
Physical quantities that need both magnitude and direction for its complete description are known as vector quantities. Physical quantities that need only direction for its complete description are known as scalar quantities.
Is mass conserved in both physical and chemical change?
neither physical or changes its property
When metamorphic rock melts and turns into lava is matter conserved?
Yes, this is a simple physical change and matter is always conserved in these. In fact, matter is always conserved except in nuclear reactions where the sum of matter and energy is conserved.
