How do you find concentration in parts per billion? Calculate the concentration in ppb by multiplying the ratio of the mass of solute to mass of solution by 1 billion, or 1, In the case of a mass ratio of 0.000005, this would give 5,000 ppb. How do you find concentration from mg L? Question […]
What is saline solution used for?
What is saline solution used for? Saline solution is usually called normal saline, but it’s sometimes referred to as physiological or isotonic saline. Saline has many uses in medicine.

What tank is used in submarines so they can float as well as sink in water?
What is the difference between negative acceleration and retardation?
What is the difference between negative acceleration and retardation? What is the difference between negative acceleration and retardation? When the acceleration is acting in a direction opposite to the velocity, it is called called retardation. Similarly we can take the direction of the velocity to be positive, and if acceleration is opposed to it is […]

What is meant by ideal op amp?
What is meant by ideal op amp? Operational amplifier: The ideal op amp is an amplifier with infinite input impedance, infinite open-loop gain, zero output impedance, infinite bandwidth, and zero noise. It has positive and negative inputs which allow circuits that use feedback to achieve a wide range of functions. Which is not the characteristic […]
Why does current decrease when charging a capacitor?
Why does current decrease when charging a capacitor? Capacitor is like a bucket which is storing electrostatic energy , as a constant voltage or current is there to provide the energy . As the charge inside the capacitor increases exponentially more the current passing through the capacitor will decrease because it won’t allow any current […]
How many types of high speed steel are there?
How many types of high speed steel are there? four different What type of steel is HSS? High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively […]
