Answer:

Blue light, shorter wavelength, brighter

Explanation:

The color of a beam of light depends on the wavelength of the light

The wavelength of blue light is short and ranges from 450 nanometers to 495  nanometers, while the the wavelength of red light is longer and ranges from 620 to 750 nm

However, the energy of the photons that produce red light are lower than those that produce blue light, therefore, blue light have higher radiant energy, and is therefore, brighter than red light

Therefore;

Blue light have shorter wavelength, (and it is) brighter (than red light, when produced from a given area)

How much work is done? A Net Force of 9.0 N acts through a distance of 3.0 m in a time of 3.0 s. The answers are 3.0 J, 9.0 J, 2
Vadim26 [7]
If the force and the motion are along the same direction (like it is here) then work is force*distance.  The time doesn't come into play until you want the power used.  So here
W=9.0*3.0=27J

Boxes are transported from one location to another in a warehouse by means of a conveyor belt that moves with a constant speed o
krek1111 [17]

Answer:

P = 15.90 W

Explanation:

given,

speed of conveyor belt = 0.56 m/s

conveyor belt move up to = 2 m      

angle made with the horizontal = 15°

mass of the box = 2.1 kg                      

rate is the force of the conveyor belt doing work on the box as the box moves up                                                  

P = F v cos ∅

P = 3 × 9.8 × 0.56 × cos 15°

P = 15.90 W
