What if time was negative? Negative time denotes moving backward to past. Till now, time is moving forward i.e.we can’t go back to our past. Where do you see negative numbers in real life? Negative numbers are used in weather forecasting to show the temperature of a region. Negative integers are used to show the […]

Why do equipotential lines have no direction?
Why do equipotential lines have no direction? Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field. What is meant by depletion region? In semiconductor physics, the depletion region, also […]
What is A and B in Mendeleev periodic table?
What is A and B in Mendeleev periodic table? Arti Gujrati answered this. 1) In Mendeleev’s periodic table, there are 8 groups and each group is divided into two sub-groups designated as A and B. Mendeleev arranged the elements according to their atomic weights. What are the three features of Mendeleev periodic table? 1 Mendeleev […]
What is the purpose of the celestial equator?
What is the purpose of the celestial equator? The celestial equator is an imaginary line that extends out from the Earth’s equator into the celestial sphere. It divides the celestial sphere in half (just like the real equator does with Earth) and is used to map stars and other celestial objects. What does celestial equator […]

What is electric potential for a dipole?
What is electric potential for a dipole? An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside an electric field without producing acceleration. A dipole is a pair of opposite charges with equal magnitudes separated by a distance, d. What is […]
What causes an atom to become positively charged quizlet?
What causes an atom to become positively charged quizlet? What causes an atom to become positively charged? -Removing an electron causes the atom to have more protons, which have a positive charge, than electrons, which have a negative charge. What causes an atom to become negatively charged? Protons are tightly bound in the nucleus and […]
What causes the process of transmutation?
What causes the process of transmutation? Transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay (qq. What is […]
Which particle is the smallest?
Which particle is the smallest? atoms Which particle has higher mass? alpha particles Do gamma rays have mass? Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through […]
