<h2>
Answer </h2>
The answer to this question is <u>407.5 g</u>
<h2>
Explanation</h2>
- The density of the substance = 1.63 g/ml
- The volum of the substance = 0.25 L
- Mass of the substance = ? (Determined)
We know that
So, 0.25 L will be equal to 250 ml. ( Unit must be same)
Formula
Se, mass of the substance is 407.5 g
Answer:
we can say that with a smaller magnitude , the field will point is in same direction
Explanation:
we have given that
solenoid is filled with a diamagnetic material and with air, magnetic field pointing along its axis in the positive x direction
so in small magnitude, the field will point is in same direction
Answer:
An instrument for measuring the density of liquids.
Explanation:
A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.
Thermohydrometers is one type of hydrometer.
