Answer:
Substance X will rise due to convection.
Explanation:
There are 6 atoms total:
-one sodium atom
-one hydrogen atom
-one carbon atom
-three oxygen atoms
Answer:
1)
Force on bar magnet = 0
Torque on bar magnet = 0
2)
Force on bar magnet = 0
Torque on bar magnet = 0.177 Nm
3)
Force on bar magnet = 0
Torque on bar magnet = 0.25 Nm
Explanation:
Part 1)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is inclined along z axis along magnetic field
then we will have
Part 2)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is pointing 45 degree with z axis then we will have
Part 3)
net force on bar magnet in uniform magnetic field is always zero
Torque on bar magnet is given as
when bar magnet is pointing 90 degree with z axis then we will have
Two atoms of the same element can have different numbers of protons
false
diff nos neutrons ... isotopes,
diff protons ... diff elements
The magnetic field lines due to a straight, current-carrying wire are circular.
<u>Explanation:</u>
The concepts of Electromagnetism brought a new revolution to the science world. The idea is the source of many new modes of power and machines that reduces the manual work. Motors are the best example of machines that run on the concepts of electromagnetism. So the concept is that a current-carrying conductor induces a magnetic field in its nearby premise.
This magnetic field can perceive by the magnetic line of forces. Now, if we pour some iron dust around a current-carrying conductor, we'll see a concentric circular pattern around the straight wire whose centre will be at the conductor axis. The pattern of these magnetic lines of force may deflect with the variation of current in the wire but remain in the circular format.
