Substances that prevent or reduce the rate of a chemical reaction are called as inhibitors.
<u>Explanation:</u>
Inhibitors are those substances that either prevent or reduce the rate of a chemical reaction. Ex: Acetanilide slows down the decomposition of hydrogen peroxide solution.
Inhibitors even reduce the effectiveness of catalysts without hindering their composition. There are primarily two kinds of inhibitors- reversible and irreversible. Where, reversible inhibitors slows the rate of any reaction, irreversible inhibitors completely prevents the unwanted reactions.
Where catalysts are used to increase the rate of a reaction, inhibitors stand as a wall for the unwanted reactions to occur. For example, in case of silver tarnishing, to prevent silver jewellery being tarnished, a thin layer of rhodium is applied on it which works like an inhibitor for formation reaction of silver sulphides (the tarnish).
Answer:
is his final displacement from the point A after 60 seconds.
Explanation:
Given:
Cyclist is moving away from A.
- velocity of cyclist,
- displacement of the cyclist from point A at the time of observation,
- time after which the next observation is to be recorded,
Now as the cyclist is moving away from point A his change in displacement after the mentioned time:
<u>Now the the final displacement from point A after the mentioned time:</u>
6. "The electric field caused by an electron is weakest near the electron" is FALSE.
7. "An electric field becomes weaker as distance from the electron increase" is TRUE.
<u>Explanation:</u>
The "electrical field" covers the electrical charge and exerts, attracts or repels other charges in the field.The electric field caused by an electron is strongest near the electron while it become weak as distance from the electron increase.
The reason behind is, at a point the direction of the field line is at that point the direction of the field. The relative magnitude of the electric field will be proportional to the field line density. The field is strongest where the field lines are near together and when the field lines are at increasing distance the field is weakest.
Answer:An inelastic collision is one in which the internal kinetic energy changes (it is not conserved). A collision in which the objects stick together is sometimes called perfectly inelastic because it reduces internal kinetic energy more than does any other type of inelastic collision.People sometimes think that objects must stick together in an inelastic collision. However, objects only stick together during a perfectly inelastic collision. Objects may also bounce off each other or explode apart, and the collision is still considered inelastic as long as kinetic energy is not conserved.
