As light shines from air to another medium, i = 26.0 º. The light bends toward the normal and refracts at 32.0 º. What is the index of refraction? A)0.827
B)0.944
C)1.21
D)1.06
Answers
The equation for the index of refraction is n = sin(theta1)/sin(theta2) where theta1 is the refracted angle and theta2 is the angle in a medium. Plugging in the values for the index of refraction, n = sin(32)/sin(26) we get 1.21. the answer is letter C. The index of refraction is always greater than 1.
That answer is wrong it is not 1.21 just turned it in and was wrong

The type of motivation is present here is d. Intrinsic to extrinsic
The following information should be considered:
- Intrinsic motivation comprise of performing a task since it's personally rewarding to you.
- While on the other hand, Extrinsic motivation comprise of finishing a task since of outside causes like avoiding punishment or collecting a reward.

Final answer:
John's motivation to improve his Social Studies project for a scholarship is extrinsic, as it involves external rewards or incentives.
Explanation:
The type of motivation present when John decides to work harder on his Social Studies project to be eligible for a scholarship for college is extrinsic motivation. This motivation is driven by external rewards or incentives, such as the possibility of receiving a scholarship, which is a tangible benefit that John would receive in exchange for his improved performance. The correct answer to the question is B. Extrinsic.
For example, similar to Carl who mows the yard for money, John is motivated by an external reward—the scholarship. When comparing intrinsic versus extrinsic motivation, intrinsic motivation comes from within the individual, for the enjoyment or satisfaction of the task itself, whereas extrinsic motivation comes from outside sources, such as rewards or the promise of a scholarship. This principle also applies to cases of educational pursuits and motivations within various workplace settings.

Electromagnetic energy
Explanation
Sunlight is a radiation. From the electromagnetic spectrum we have visible light and ultraviolet radiation whose source is the sunlight.
All electromagnetic radiation possess some energy given by E=hf.
Since we have seen that sunlight is in the electromagnet spectrum, it is a form of energy which is electromagnetic.
Final answer:
Sunlight is a form of energy called electromagnetic energy
Explanation:
Sunlight is a form of energy that is emitted by the sun as electromagnetic radiation. This radiation exists in different wavelengths, each with its own characteristic energy. The visible light that we can see is just one type of energy emitted from the sun. It is specifically a subset of electromagnetic radiation that includes visible light, ultraviolet (UV) light, and other wavelengths.
It is produced by nuclear fusion in the sun's core and travels to Earth through space. Sunlight is essential for life on Earth, as it provides energy for photosynthesis in plants, regulates climate, and is a primary source of light and heat for our planet.

Answer:
Distance traveled will be
Explanation:
We have given speed of the light
We have to find the distance traveled by light in 1 year
We know that 1 year = 8760 hour
And 1 hour = 60×60 = 3600 sec
So 1 year
We know that distance = speed × time
So distance traveled by light in one year
We have to fond the distance in km
As we know that 1 km = 1000 m
So
Final answer:
Radio messages will travel approximately 9.46 x 10^12 kilometers in exactly one year.
Explanation:
Radio waves travel at the speed of light which is approximately 3.00 x 108 m/s.
To find out how many kilometers radio messages will travel in exactly one year, we need to first convert the speed of light into kilometers per second.
Since there are 1000 meters in a kilometer, we divide the speed of light by 1000 to convert from meters to kilometers. Then, we multiply this value by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds) to get the total distance traveled in kilometers.
In summary, radio messages will travel approximately 9.46 x 1012 kilometers in exactly one year.
