Answer:

16.Difference between a Bar Magnet and a Solenoid

The bar magnet is a permanent magnet whereas a solenoid is an electromagnet ie, it acts like a magnet only when an electric current is passed through. ... The poles of the bar magnet are fixed whereas for a solenoid the poles can be altered.

17.When you press a doorbell button, you complete an electrical circuit that allows household electricity to flow through the doorbell's internal electromagnet. The magnetic field generated by the electromagnet is then used to power a mechanism that creates the doorbell sound. Doorbells are low-voltage devices.

stepan [7]
The fern should be found on the west side of the mountain ranges at higher elevations because the prevailing winds are from the west off the Pacific Ocean so bring moisture in the clouds and as the clouds rise up over the westernmost mountains they cool off and precipitate so in the warm seasons rain would be concentrated in this area and higher up would be cooler.

how does water role in photosynthesis explain increased biological productivity in area of heavy precipitation​
s344n2d4d5 [400]

Answer:

Photosynthesis takes in energy from the sun, CO2 and H2O and produces Glucose(don't know formula), O2 and H2O. This means the water is needed for the reaction but isn't transformed. This means that in areas with greater average rainfall, plants generally grow faster.

Please help with my recent questions if this helped. :)

expeople1 [14]

Answer:

Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications

The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.

a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:

  • Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.
  • Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.
  • The sample should be ashed for 12-18 hrs , more than this can damage the required ash content.
  • platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.
  • The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.

b. The result that occur due to above errors such as the temperature, time,  tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.
