A monument has a height of 348 ft, 8 in. Express this height in meters. Answer in units of m.
tensa zangetsu [6.8K]

Answer:

The height of mountain in meter will be 106.2732 m

Explanation:

We have given height of mountain = 348 ft,8 in

We know that 1 feet = 0.3048 meter

So 348 feet =348\times 0.3048=106.07meter

And we know that 1 inch = 0.0254 meter

So 8 inch 8\times 0.0254=0.2032m

So the total height of mountain in meter = 106.07+0.2032 = 106.2732 m

The height of mountain in meter will be 106.2732 m

An atom emits a light wave with a wavelength of 449 nm. what type or color of light does this represent?
Vinvika [58]
The visible spectrum ranges from 390 nm to 700 nm. the visible spectrum consist of the red ( 620 - 750 nm ) , orange ( 590 - 620 nm ) , yellow ( 570 - 590 nm ) , green ( 495 - 570 nm ) , blue ( 450 - 495 nm ) and violet ( 380 - 450 nm ) so the wave length 449 nm will produce a violet color
