Answer: light can transmitted through long fiber optic strand as a result of total internal reflection

Explanation:

Total internal reflection occur when a right ray incident at the interface of two less dense media is completely reflected back to a denser medium, as a result of a greater angle than the critical angle.

Optical fibers use total internal reflection to transmit light. Light passing through the inner core of the optical fiber strand is reflected back rather than being refracted to the cladding.

Note: the optic fiber is made of dense solid glass core (the inner) surrounded by less dense cladding (outer)

Total internal reflection. Although I'm not 100%

Answer:

Four fundamental forces are gravitational, electromagnetic, strong, and weak.

Explanation:

The gravitational and electromagnetic interactions, which produce significant long-range forces whose effects can be seen directly in everyday life and the strong and weak interactions, which produce forces at minuscule, subatomic distances and govern nuclear interactions.

A circuit contains a 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current

Vitek1552 [10]

The formula that links voltage (V), resistance (R) and current intensity (I) is

$V=RI$

Solve this formula for I to get

$I=\dfrac{V}{R}$

Plug your values for V and R and you'll get the current.

"In a pure substance all the particles must be identical; therefore pure substances are composed only of elements." Do you agree

kenny6666 [7]

I do not agree with the statement.
The "substance" can be a compound. It's "pure"
as long as there's nothing else in it but its name.

'Pure' water is 100% H₂O with nothing else in it.
'Pure' table salt is 100% NaCl with nothing else in it.
'Pure' carbon dioxide is 100% CO₂ with nothing else in it.

These example substances are all compounds, not elements.
