Here we have been given two charged body W and X.
We are asked to determine the nature of charge.
Before coming into conclusion, first we have to understand the electric field lines.
The electric field lines are pictorial representation of imaginary lines which are drawn to denote the electric field in a graphical way.
The electric field line starts from a positive charge and ends at a negative charge.It means for positive charges the electric field lines are outward and for negative charges the filed lines will be inward.
In the given diagram,the filed lines for W is towards W itself.The same is also in case of X.
Hence both the charges must be negative in nature.
Hence the correct answer to the question will be B i.e W negative and X: NEGATIVE.
Because of the moon and earth. The earth spins on its axis (it's tilted) and the moon orbits the earth every 28 days.
It indicates that car is at rest at all time (t) :-)
Hope it helped you. ✌
Answer:
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
Explanation:
Answer: The acceleration of an object will decrease
Explanation: This happens as if the mass of an object increases then the acceleration of the body decreases as acceleartion is directly proportional to the mass of the body by Newton's 2nd law F=MA we can say the more mass an object has the more net force needs to be applied to make it start accelerating
