What happens to the speed of a body when a force is applied? Answer. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force. The body might speed up, slow down or change direction, after which, the body will continue moving at a […]

Is the law of reflection always true?
Is the law of reflection always true? Law of Reflection One thing is true of both regular and diffuse reflection. The angle at which the reflected rays leave the surface is equal to the angle at which the incident rays strike the surface. According to the law of reflection, the angle of reflection always equals […]
What is the relationship between melting point and boiling point?
What is the relationship between melting point and boiling point? The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the melting point is the temperature at which a material changes from a solid to a liquid (melts). Keep in mind that a material’s melting point […]
What is the half life of a first-order reaction if time required to decrease?
What is the half life of a first-order reaction if time required to decrease? Concentration is reduced to 25%. It means it takes two half-lives to decrease the concentration of reactant from 0.8 M to 0.2 M in first-order reaction. Hence, half-life of the reaction is 12/2 = 6 hours. The half life of reaction […]
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle?
When we stop pedaling a bicycle it comes to rest after sometime describe the forces responsible for the change in state of motion of the bicycle? Solution. If we stop pedalling a bicycle, moving at a uniform speed, it does not go on moving forever. It eventually comes to rest after some time. This is […]

What happens if you connect an ammeter in parallel?
What happens if you connect an ammeter in parallel? If we connect an ammeter in parallel there will be higher flow of current through the ammeter, it would cause a short circuit, resulting in damaging the ammeter and the circuit. Ammeter has a very low resistance. So the current which we measure in a circuit […]
Can 200 decibels kill a human?
Can 200 decibels kill a human? Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and […]
