What are collinear forces? When the line of action of forces is acting along the same line for a system, such force is defined as the collinear force. Stay tuned with BYJU’S to learn more about other concepts such as concurrent forces. What are coplanar forces? Coplanar forces acting at a point When all forces […]
Why is Earth magnetic field weakening?
Why is Earth magnetic field weakening? The forces in the core and the tilt of the magnetic axis together produce the anomaly, the area of weaker magnetism – allowing charged particles trapped in Earth’s magnetic field to dip closer to the surface. What is the major cause of the earth’s magnetic field? The Earth’s magnetic […]
How do you know if total mechanical energy is conserved?
How do you know if total mechanical energy is conserved? If only internal forces are doing work (no work done by external forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved. Is mechanical energy conserved between A and B? Explanation: Mechanical energy […]
What are the 3 indicators?
What are the 3 indicators? Indicators can be described as three types—outcome, process or structure – as first proposed by Avedis Donabedian (1966). The national safety and quality indicators of safety and quality in health care recommended in this report include indicators of all three types. What are indicators and examples? Indicators Name Acid Color […]
What does rifling do to a bullet?
What does rifling do to a bullet? Rifling works by spinning the projectile about its axis, causing gyroscopic forces that spin-stabilize it throughout its flight; tighter rifling will spin a bullet faster, while looser rifling will spin a bullet slower. How far can a 22 bullet travel? around 1.5 miles How do police match a […]
What are three types of models in science?
What are three types of models in science? Physical models, mathematical models, and computer models are common types of scientific models. How are models created? In some situations, models are developed by scientists to try and predict things. Using this information and an understanding of how these cycles interact, scientists are trying to figure out […]
What is meant by the latent heat?
What is meant by the latent heat? Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance […]
What type of mutation is caused by radiation?
What type of mutation is caused by radiation? Since this is a random process, such effects are now called stochastic. [100] Two important stochastic effects of radiation are cancer, which results from mutations in nongerm cells (termed somatic cells), and heritable changes, which result from mutations in germ cells (eggs and sperm). What is the […]

Is a polarizing filter necessary?
Is a polarizing filter necessary? Low light situations won’t benefit from a polarizer because you’ll need all the light you can get for fast shooting. If you want reflections, like in a lake scene, use a circular polarizer so that you can take a shot WITH the polarizer engaged and another shot WITHOUT the polarizer […]
