Im pretty sure its neptune. Its mot pluto because its not a planet. Good luck.
The sentence can be completed as follows:
"<span>The wavelength range of colors visible to humans ranges from 350 nm to 750 nm. light that most of us perceive as red is at 750 nm."
In fact, each different color is associated to a different sub-range of this range of wavelengths. Approximately, they are:
- violet: 350-450 nm
- blue: 450-495 nm
- green: 495-570 nm
- yellow: 570-590 nm
- orange: 590-620 nm
- red: 620-750 nm</span>
Answer:
fluorescent bulb
Explanation:
A fluorescent bulb is what produces light.
It produces light by passing electric current through a gas to
A fluorescent lamp, is a low-pressure mercury vapor and a gas-discharge lamp that uses fluorescence to produce visible light. like the ones we see. An electric current in the gas excites mercury vapor, and that produces a short wave ultraviolet light and well that causes a phosphor coating on the inside of the lamp to glow. i tried making this sound as simple as possible.
i hope this really helps you !! thanks this and mark this as brainliest !!!
Answer:
Torque is 93 Nm anticlockwise.
Explanation:
We have value of torque is cross product of position vector and force vector.
A force of 38 N, directed 30° above the x axis in the x-y plane.
Force, F = 38 cos 30 i + 38 sin 30 j = 32.91 i + 19 j
A particle is located on the x axis 4.9 m and we have to find torque about the origin on the particle.
Position vector, r = 4.9 i
Torque, T = r x F = 4.9 i x (32.91 i + 19 j) = 4.9 x 19 k = 93.1 k Nm
So Torque is 93 Nm anticlockwise.
