What happens when two magnets are placed side by side? Opposite poles of a magnet attract each other, whereas like poles repel each other. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible. Is Venus a permanent magnet? Venus is a […]
What is scalar product explain?
What is scalar product explain? “Scalar products can be found by taking the component of one vector in the direction of the other vector and multiplying it with the magnitude of the other vector”. It can be defined as: Scalar product or dot product is an algebraic operation that takes two equal-length sequences of numbers […]

What are the three main characteristics of matter?
What are the three main characteristics of matter? Three States of Matter Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. Liquid matter is made of more loosely packed particles. Gaseous matter is composed of particles packed so loosely that it has neither […]
What happens to the capacitance value when the gap between the two plates is doubled?
What happens to the capacitance value when the gap between the two plates is doubled? Increasing the gap will decrease the capacitance. V2=QC2=QC12=2QC1=2V1. How will the capacitance of a capacitor change if its plate area is doubled and distance between plates is halved * 2 points? Answer. The capacitance between plates will reduce to half […]
Can scientists predict earthquake?
Can scientists predict earthquake? While part of the scientific community hold that, taking into account non-seismic precursors and given enough resources to study them extensively, prediction might be possible, most scientists are pessimistic and some maintain that earthquake prediction is inherently impossible. Can earthquakes be predicted 2020? No. Neither the USGS nor any other scientists […]
What is the working principle of inductor?
What is the working principle of inductor? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a […]
Which of the following is not considered a region of the spinal cord?
Which of the following is not considered a region of the spinal cord? The d. pelvic region is not considered a region of the spinal cord. Which cells form myelin in the spinal cord? Schwann cells make myelin in the peripheral nervous system (PNS: nerves) and oligodendrocytes in the central nervous system (CNS: brain and […]
Why does gas pressure increase when more particles are added?
Why does gas pressure increase when more particles are added? Adding more molecules of a gas increases the number of collisions between the molecules and the walls of the container. This raises pressure. By their very nature, gases can be compressed, so if the same gas can be put into a smaller container, it will […]
What is the study of waves called?
What is the study of waves called? Acoustics is the branch of physics concerned with the study of sound (mechanical waves in gases, liquids, and solids). A scientist who works in the field of acoustics is an acoustician. The application of acoustics in technology is called acoustical engineering. What does LW mean? Lucky Win What […]
