Suppose you observe a binary system containing a main-sequence star and a brown dwarf. The orbital period of the system is 1 year, and the average separation of the system is 1 AUAU . You then measure the Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf, finding that the orbital speed of the brown dwarf in the system is 22 times greater than that of the main-sequence star.

A single polarizer will stop _____ of the incoming light. less than 50% 50% more than 50% but less than 100% 100%

Answers

So we want to know how much light will a single polarizer stop. Since the polarizer intensity formula is I=I0cos^2(a), where I is the intensity, I0 is the initial intensity and a is the angle of the light's initial polarization direction and the axis of the polarizer. Also, the average of cos^2a is 1/2 so I=(1/12)*I0. and I/I0=1/2 or 50%. So the light that passes trough one polarizer has 50% of the initial intensity. And the correct answer is 50%.

The answer is 50%. Remember, it's a single polarizer, not two of them.

Adding an organism to a food chain does not affect the other members of the food chain, but removing an organism does.

Answers

This is false. Say you have a food chain where a monkey is the top predator. Then you introduce something that eats what the monkey does. The monkey populations will plummet and that means that the things they eat will start to get more numbers. Adding and subtracting animals throws everything out of order.

Removing any level from an ecosystem disrupts a delicate balance that may have ;and a diverse, with many levels and intricate relationships between organisms. More predators kill more prey, which, along with food scarcity, decreases the an attempt to control the population, but it had no effect on habitat degradation.

List 3 pieces of evidence for the Earth’s spherical shape

Answers

Answer:

1.time zones

2.The coriolis effect

3. triangles

Explanation:

1. day and night happen at different times at different places; it's always day somewhere and night another.

2. the coriolis effect means freely moving things (like cannonballs or hurricane winds) are deflected to the right - but only if your north of the equator if you're south of the equator they're deflected left.

3. if you walk a certain distance and make three right angle you can successfully make a triangles with three 90 degree angles which is impossible on a flat surface.
