Earth is a good conductor. The electrons are attracted to the sphere known as ground wire as it supplies a conducting path to the ground. The... View Article
The Pulley System makes use of a disk-shaped block that a rope wraps around to create a simple machine. A pulley helps to reverse the direction... View Article
While free-falling, gravity is the only force acting on the body. As gravity cannot be felt without any opposing force, there would be no... View Article
Newton’s second law of motion states that f = ma; the net forces (f) acting on a body of mass (m) to give it acceleration (a). If the only... View Article
The centripetal force acts perpendicular to the object path, towards the centre of the curve. Centripetal force results in the change of the... View Article
Which of the following conditions is true if enthalpy is negative and the entropy is positive? a) ?G is negative at high temperature b) ?G is... View Article
The NPN transistor is designed to pass the electrons from the emitter to the collector. The emitter “emits” electrons into the base, which... View Article
We use Pascal’s triangle because the triangular arrangement of the numbers made it easy for the calculations of probabilities that are involved... View Article
There is no alpha hydrogen in benzaldehyde because the functional group here is carbonyl and the alpha carbon to this is the carbon attached to... View Article
Boiling of an egg is not an example of convection. It is an example of conduction. As the heat is conducted from the boiling water to the egg.... View Article
Iodoform test is used for distinguishing between methanal and ethanal. When ethanal reacts with iodine and NaOH solution, there is a formation... View Article
The charge of the alkali metals is +1. This is because they lose the electron from the outer shell thus forming cations. Stay tuned with BYJU’S... View Article
Adsorption is a spontaneous process because there is a force of attraction existing between the adsorbate and adsorbent which releases heat... View Article
The null point of galvanometer is defined as the point at which the galvanometer shows no deflection as there is no flow of current through the... View Article
Yes, an atom can make 8 bonds. For example, Xenon can form a compound XeO4, and it makes 8 bonds. Stay tuned with BYJU’S to learn more about... View Article
The acidic strength increases down the group because the bond strength decreases down the group. Stay tuned with BYJU’S to learn more about... View Article
