Answer:
Sound and light are similar in that both are forms of energy that travel in waves.
Explanation:
They both have properties of wavelength, freqency and amplitude. ... Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.
Answer:
(A) 
Explanation:
Given:
Charge of one particle (q₁) = -0.0050 C
Charge of another particle (q₂) = 0.0050 C
Separation between them (d) = 0.025 m
We know that, from Coulomb's law, electric force acting between two charged particles is given as:
Plug in the given values and solve for electric force, 
. This gives,
Therefore, option (A) is correct. Negative sign implies that the nature of electric force is attraction.
Here's the <em><u>solution</u></em>,
Let the <em><u>shares</u></em> be 2x, 3x and 5x according to their shared <em><u>investment</u></em> ratio,
now, we know :
=》2x + 3x + 5x = 30000
=》10x = 30000
=》x = 3000
So, value of x = 3000
hence, the <em><u>share</u></em> of each <em><u>shareholder</u></em> is :
- kamal = 2x = 6000
- kamala = 3x = 9000
- Krishna = 5x = 15000
