Answer:
A.9.0 A
Explanation:
This is multiplication then add.
3*2+3=9.0
And that is how we get the answer.
Because he left the clear acrylic balls in the sun for a long time so they could have melted a bit so that would be why you got mad at him
Answer:
V = I(R+r)
Explanation:
According to ohms law, the current (I) passing through a metallic conductor at constant temperature is directly proportional to the potential difference (V) across its end.
Mathematically, V= IR where V is the potential difference
I is the current
R is resistance
Given emf (E) = IRt... (1)
where E is the emf
Rt is the total equivalent resistance
The external resistance Rv is connected in series with the internal resistance 'r' to give total equivalent resistance Rt = (R+r)
Substituting in equation 1
E = I(R+r)
The equivalent potential difference V = I(R+r)
The answers to your questions are as written below:
- The objects that represents a negatively charged particle is : Image B
- The object that represents a positively charged molecule is : Image A
- The object that represents an uncharged molecule is : Image C
- The object the will not move when in an electric fied is : Image C
<h3>Different types of charges molecules</h3>
A negatively charged molecule move inwards when placed in an electric field while positively charged molecule placed in a electric field will move outwards the electric field.
A neutral/uncharged molecule will remains still when placd in an elctric field due to the absence of charges.
Hence we can concude that the answers to your questions are as listed above.
