I think the correct answer from the choices listed above is option B. A parallel circuit differ from a series circuit in a sense that a <span>series circuit has one path for electrons, but a parallel circuit has more than one path. In a parallel circuit there two or more paths for current to flow while a series circuit only has one.</span>
Answer:
change in entropy is 3.3034 ×
Explanation:
give data
thermal energy Q = 155 J
temperature T = 340 K
to find out
change in entropy
solution
we know change in entropy formula that is
change in entropy = Q / ( K×T ) ..............1
here K is boltzmann constant that is 1.38 ×
kg-m²/s²
put these value in equation 1 we get
change in entropy = Q / ( K × T )
change in entropy = 155 / ( 1.38 ×
× 340 )
change in entropy = 3.3034 ×
so change in entropy is 3.3034 ×
Answer:
The charge on the bead is 
Explanation:
From the question we are told that
The mass of the bead is 
The magnitude of the electric field is 
The acceleration of the bead is 
Generally, the electric force on the bead is mathematically represented as

Where q is the charge on the bead
Now the gravitational force opposing the upward movement of the bead is mathematically represented as

Generally the net force on the bead is mathematically represented as

=> 
Now substituting values
