m/sec is the unit of velocity.
Explanation:
The displacement is a vector quantity. It is a measure difference between the end and start point of a moving object.
The displacement of an object is measured in metres, kilometers, centimeter or inches. But the SI unit of displacement is always converted to metres.
The time may be in minutes, hours or second, but the SI unit of time is sec
velocity with respect to displacement is defined as rate at which displacement changes with time.
from the formula :
velocity=diplscement/time
= m/sec
So the SI unit of velocity is m sec
<h2>Cogeneration is the process of production of electricity from steam and cosuming the waste steam in chemical processes.</h2>
Explanation:
cogeneration prodeuces electricity from steam and uses steam in other chemical reactions simultaneously.
Answer:
"a chemical reaction in which acid and a base react quantitatively with each other"
Explanation:
It is a constant-volume type calorimeter that measures the heat of a particular reaction or measures the calorific value of the fuels. Bomb calorimeters are built in such a way that they can withstand the large pressure produced within the calorimeter due to the reaction or burning of fuel.
