Heterogeneous mixture refers to a mixture consisting of various components and sizes. The mixture does not appear as a uniform composition.
Hence to separate it, we will make use of the different sizes and weights.
So it is by their densities. (B)
Answer:
Density of the rock = 2.82436 g/cm³
Explanation:
We are given that:
We are also given that:
mass of rock = 8 grams
volume of rock = 2.8325 cm³
Substitute with the given values in the equation to get the density as follows:
g/cm³
Hope this helps :)
According to the statement we can deduce that the resulting amplitude of the wave pulse is zero when there is a destructive interference of two pulses and the chain is straight. At this point the potential energy will be zero, therefore when applying the energy conservation theorem, the potential energy must be equal to the kinetic energy and be conserved. The potential energy will be totally transferred as kinetic energy and therefore that will be the only energy present in the string.
Thus, the option C is correct.
