Answer:
B
Mass of cylinder + mass of water - mass of cylinder = mass of water
Answer:
Radius of aluminium sphere which has same mass as of sphere of iron with radius 14 m is 40.745 meters.
Explanation:
Let the radius of aluminium sphere be
From the relation between density, mass and volume we know that
Applying equation 'i' separately to iron and aluminium sphere we get
Equating the masses of iron and aluminium spheres we get
Answer:
Explanation:
Given that,
Mass, m = 27 grams
Volume of the substance, V = 15 cm³
We need to find the density of the substance. We know that, the density of an object is given by mass per unit volume. So,
So, the density of the substance is equal to .
The answer to this question is: absolute
Absolute threshold is the lowest intensity of a stimulus that can be detected by an organism. This normal value was determined by taking data of the lowest intensity of the populaion, then taking the 50% percentile value of the data. That means the absolute threshold would be right for half of the population.
