Answer:
• The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge.
• At a distance d from a dipole, where d >> 5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^3
• A dipole consists of two particles whose charges are equal in magnitude but opposite in sign
Explanation:
A dipole is a pair of magnetized, equal or oppositely charged poles the are being separated by a distance.
The statements about a dipole that are correct are:
• The electric field at any location in space, due to a dipole, is the vector sum of the electric field due to the positive charge and the electric field due to the negative charge.
• At a distance d from a dipole, where d >> 5 (the separation between the charges), the magnitude of the electric field due to the dipole is proportional to 1/d^3
• A dipole consists of two particles whose charges are equal in magnitude but opposite in sign
There was less work done when there was less force applied or there was less movement. I just answered this on my test and got it right.
Answer:
Explanation:
capacitance of air capacitor C = charge / volt
C = 6.39 x 10⁻⁵ / 2.67
= 2.39 x 10⁻⁵ Farad
After inserting dielectric between plates , the capacitance of capacitor becomes C₁ where
C₁ = 6.03 x 2.39 x 10⁻⁵
= 14.41 x 10⁻⁵ Farad
The voltage of the capacitor will remain the same as earlier that is 2.67 V because it remains connected with the charging source .
New charge on the capacitor = new capacitance x voltage
= 14.41 x 10⁻⁵ x 2.67
= 38.47 x 10⁻⁵ C .
Answer:
B. less than mg
Explanation:
A person's weight changes as he rides an elevator at a constant velocity. If the elevator is moving downward,<u> the person's weight becomes lesser.</u> He is considered to be in "free fall" due to <em>gravity.</em> However, the opposite happens when the elevator goes upward. The person will feel heavier because he is going against gravity. This means his weight is more than his actual weight. If the person will stand on an elevator that doesn't move, his weight will just be the same. All of these is due to <em>Newton's Second Law of Motion</em> where an object's acceleration relies on its <em>force</em> and<em> mass.</em>
