We determine the mass of the metal in grams by weighing it using the balance.
Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way:
1.measure amount of water in the graduated cylinder.
2. Place metal into the graduated cylinder
3. Measure the amount of water in the graduated cylinder
4. Subtract step 1 from step 3. The difference is the metal's volume.
Once we have found out the mass and the volume then we calculate the density using the formula:
Density = Mass/Volume.
We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.
Answer:
Posterior column mediates a pathway called as posterior column medial lemniscus pathway in central nervous which is responsible for mediating certain sensations like touch, vibration etc. Damage to the left posterior column unable to transmit signals to the primary somatosensory cortex in the gyrus and parietal lobe of the brain.
Explanation:
- The spinal cord and cerebrum is connected by some specialized tract called as white matter tract. These tracts are either ascending or descending.
- The another name of ascending pathway is known as medial lemniscus pathway.
- The origin of this pathway takes place within posterior column of the spinal cord.
- Posterior column medial lemniscus pathway is important as it transmit signals to the cerebrum which is responsible for generating impulse like vibration, touch etc.
- Thus damage to this column can't be able to transmit signals to different parts of cerebrum and thus impulse like touch, vibration,pressure etc will not generate.
I live in letter D in summer and letter B in winter.
<h3><u>Explanation:</u></h3>
In the diagram the letter D represents the summer solstice and the letter B represents the winter solstice. But the letter A and C represents the equinoxes that are present in the month of March and September. Here in India the country lies above tropic of Cancer. So the condition here is like the temperate region. So during summer the sun's rays directly fall on the country as well as during winter the country receives oblique sun rays. Thus from the diagram we can see see that the letter B represents the condition of earth when the sun's rays are not directly falling on earth. So it's winter solstice .
In the letter D we can see that the earth is going through the summer solstice because sun's rays are directly falling on the earth. So it's summer at that time.
Answer:C. Creating helium from hydrogen in its core
Explanation: Stars produce energy majorly by nuclear fusion. The process of creating helium by merging hydrogen atoms to produce deuterium which in turn is converted to helium.
