The net force is force applied + force friction ( which is negative ) Unfortunately for some reason the numbers are negative, could you ask your teach about that?
Btw, left is usually force fric. which makes it negative
(-750+-250+-550)+1563 = net force
(-792+-632+-100)+(400+900) = net force
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.
Answer:
F = [M] × [L1 T-2] = M1 L1 T-2.
Explanation:
Therefore, Force is dimensionally represented as M1 L1 T-2.
Answer:
B. X-rays
Explanation:
From the given choices, x-rays will have the highest energy of the given waves.
The energy of electromagnetic waves is highly dependent on their frequency and wavelength.
Electromagnetic waves with a high frequency and small wavelength will have higher energy compared to those with low frequency and high wavelength.
X-rays are one the most energetic waves on the periodic table. They have a very high frequency and low wavelength.
