MrRissso [65]3 years ago
6 0

Answer:

Explanation:

we know that 1 km =1000 m and 1 hour=3600 sec

therefore

15 km/hr=15*1000 m/3600 sec=4.167 m/s

Answer:

Jupiter

Explanation:

For this space trip, the distance to the planet must be taken into account, so Because Jupiter is much closer it should be the correct choice

.

It must also be taken into account that Saturn has a series of rings, for which the ship has a probability of colliding with one of these in one of its turns, therefore taking this into account, Jupiter must also be chosen.

Do you think a population besides the moon jellies’ consumer population (sea turtles) and resource population (zooplankton) coul
kondor19780726 [428]

Answer:

I didn't quite understand your question, but the moon jelly population will increase if there are either more zooplankton or less sea turtles.

More zooplankton means more food => higher population

Less sea turtles means that the moon jelly will be lest often consumed => higher population

Wewaii [24]

A flash of red light and a flash of blue light enter a glass cube perpendicular to its surface at the same time. after passing through the block, the red light pulse exits first.

For any medium, other than vacuum, the index of refraction for red light is slightly lower (closer to 1 ) than that for blue light. This means that when light goes from vacuum (or air) into glass, the red light deviates from its original direction less than does the blue light. Also, as the light reemerges from the glass into vacuum (or air), the red light again deviates less than the blue light. If the two surfaces of the glass are parallel to each other, the red and blue rays will emerge traveling parallel to each other, but displaced laterally from one another.

what is refractive index?

The ratio between the speed of light in medium to speed in a vacuum is the refractive index. When light travels in a medium other than the vacuum, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed light.

A light source emits light with dominant wavelengths in the range of 650 to 690 nm. what is the principle color of light emitted
dsp73

Answer:

Please see below as the answer is self-explanatory.

Explanation:

  • The visible range extends roughly from 400 nm (violet) to 700 nm (red).
  • Below the violet is the ultra-violet spectrum (with higher energy) and above red, we have the infra-red spectrum.
  • The wavelengths in the range of 650 to 690 nm have red as the dominant color.
