Answer:
Option D.
Explanation:
Methods of charging:
1. By friction: when two materials of different electro-negativities rub against each, electrons transfer from one material to another.
2. By induction: When a charged body is brought near an uncharged body, the later gets polarized.
3. By conduction: when electrons from one body to another uncharged while contact, it is known as charging by conduction.
Here, a flower is analogous to an electron. A box of candy is positive charge. A bouquet of flowers is like a charged body which is brought near an uncharged body. It induces charge on ti it by causing it to transfer electron to another.
Thus, option D is correct.
I believe the answer is organelles,
Watt = voltage x ampere
750 = 220 x ampere
Ampere = 750 / 220
Resistance = voltage / ampere
= 220^2 / 750
The top pair of pliers failed to loosen a stubborn bolt, but the bottom pair successfully removed it. Because the contact between the bolt and the pliers working surface is less.
<h3>What is mechanical advantage ?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of the given mechanical machine.
The efficiency to open the stubborn bolt depends upon the contact between the working surface of the pliers and the bolt.
The contact between the bolt and the top pair of pliers working surface is less. Its mechanical advantage is less.
Hence, the top pair of pliers failed to loosen a stubborn bolt, but the bottom pair successfully removed it.
