<span>A microscopic magnetic region composed of a group of atoms whose magnetic fields are aligned in a common direction is called as a DOMAIN. in most materials, when these groups are randomly distributed, the substance will show ZERO magnetism.</span>
Answer:
In the second case there's no way to know what depth the bullet will penetrate into the block.
Explanation:
Since the block is on a <em>frictionless </em>surface, when hitted by the bullet, this last one could barely penetrate the surface of the block and, both, start moving as one (<em>perfectly inellastic collition</em>) since here, there's no vise to hold the block into place.
Answer: 129,600kg/day
In this question, you are given the river flow (30m3/s) and the salt concentration. Then to determine the amount of salt carried, you simply need to multiply the flow with concentration. Be careful because the unit in this question is different and need to be converted. The equation would be:
Salt = river flow x salt concentration
Salt = 30m3/s x 1000L/m3 x 50mg/L = 1,500,000mg/second
Then convert it into kg/day
Salt= 1,500,000mg/second x 10^-6 kg/mg x (3600 second/hour) x (24 hour/day)= 129,600kg/day
Answer:
The object will sink in the liquid in beaker 1.
The object will float in the liquid in beaker 2
Explanation:
The density of an object relative to the density of a fluid determines if the object floats or sink in a fluid. The density of a material is the measure of the amount of mass of that material packed into a unit volume of that material.
For the beaker 1, the liquid in this beaker has a density of 0.5 g/cc, which is lesser than the density of the object (0.85 g/cc). This means that the object will add more mass than there should be to the volume of the space it displaces within the field. This results in the object sinking in the fluid.
For beaker 2, the liquid in this beaker has a density of 1 g/cc, which is more than the density of the object (0.85 g/cc). This means that the object will add less mass than there should be to the volume of the space it displaces within the field. This results in the object floating in the fluid.
