Answer:
338N
Explanation:
Use the formula 
f is the frequency, T the string tension, M the mass, and L the length
convert units to seconds, kilograms, meters
now solve for T
sqrt(T/.005) = 65*4 = 260
T = 338N
An Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
I hope this helped you with your problem.
Answer:
When you have two materials with the same index of refraction, it means that if they are touched by a ray of light it won't have a chance, and its form would prevail.
Explanation:
The reason behind this is that in the first place. When light passes through an object of certain refraction it is modified from its natural state, allowing it to change in color to the human eye or many other effects in other perceptive elements. However, when the same light passes through two objects with the same refraction due to their physical characteristics, it doesn't change because once it comes out of the first one it will suffer the same effect from the last one. For it to change the refraction would have to be higher or lower. Then it would be modified. The reason is because the dimensions are not modified. Because at some point the ray of light has to come out of the first one to enter the second one.
