If you put a penny in each light spot the penny that the light is shining on will recive the most energy.
Answer:
1) W = 150 J
Explanation:
Work (W) is defined as the product of force F by the distance (d)the body travels due to this force.
W= F*d Formula ( 1)
The work is positive (W+) if the force has the same direction of movement of the object.
The work is negative (W-) if the force has the opposite direction of the movement of the object.
The component of the force that performs work must be parallel to the displacement.
Work done to lift the floor box to its final position
We apply the formula (1)
W= F*d
W = (100 N)*(1.5 m)
W = 150 J

Answer:
A) color
Explanation:
Visible light is a portion of the electromagnetic spectrum, that includes wavelengths approximately from 380 nm to 750 nm.
It is the only part of the electromagnetic spectrum that the human eye can see. Depending on the wavelength of the light in this region, we perceive the light as a different color.
Therefore, each color is associated to a different range of wavelength, as follows:
Violet 380 - 450 nm
Blue 450 - 495 nm
Green 495 - 570 nm
Yellow 570 - 590 nm
Orange 590 - 620 nm
Red 620 - 750 nm
