Answer:
Distance between earth and sun, around 150 million km, is defined as one Astronomical Unit (AU). The radius of the Sun, Run is around 700,000 km. The orbital speed of Earth is around 30 km/s.
Explanation:
WILL PICK BRAINLIEST!!!!!!!!!!!!!!
calculate-
On this model 40 AU = 1 meter.
A light year, the distance light travels in 1 year, is 63,240 AU
The nearest star is *Proxima Centauri is 4.2 light years.
i think im supposed to find the distance per meter or something
[tex]1 \times 12 = 63240 \sqrt{4.2} [/tex]
1x4<3=12
Which statement correctly describes the relationship between wavelength, frequency, and energy?
A) Waves with a short wavelength have a high frequency and low energy.
B) Waves with a short wavelength have a high frequency and high energy.
C) Waves with a short wavelength have a low frequency and low energy.
D) Waves with a short wavelength have a low frequency and high energy.
Answer:
A.
Explanation:
maybe because the frequency of a wave increases due high wave and low energy. Hope this helps :3

How would you explain the differences between graphing x > 4 and x ≥ 4 to a peer who missed this lesson?
Answer in complete sentences.
Explanation:
x>4 that is x is GREATER THAN 4 but not equal to but it's its the other one than it mean that x can be 4 or more nothing less
Answer:
x > 4 means that the value of { x } is greater than 4 while x ≥ 4 means that the value of { x } is greater or equal to 4.

short essay Question
Answer:
In wind turbines, the blades rotate due to the wind.
Explanation:
In wind turbines, the blades rotate due to the wind. While the blade rotates the generator connected to it also rotates. Thus the kinetic energy from the wind initiates the electric generator which in turn produces the electricity.
Thus the kinetic energy of the wind is converted to electricity.
Hope this helps!

Answer: 4
Explanation:
The answer to this question is number 4 as part 4 is where the roller coaster is slowing down. This means that it is gaining stored potential energy and in turn, losing kinetic energy. Furthermore, an object gains potential energy as it goes higher, usually.

You can take your heart rate using:
Question 4 options:
Radial Pulse Point
Carotid Point
None of the above
A and B
Answer:
A I think
Explanation:
at the wrist lightly press the index and the middle fingers of one hand on the opposite wrist just below the base of the thumb at the neck lightly press the side of the neck just below the jawbone count the number of beats in 15 seconds and multiply by four and that's your heart rate
You can take your heart rate using both the Radial Pulse Point and the Carotid Point. The correct answer is "A and B."
1. Radial Pulse Point: The radial pulse is taken by placing two fingers (usually the index and middle fingers) on the radial artery, which is located on the wrist, on the same side as the thumb. By feeling the pulsations, you can count the number of beats per minute, which gives you the heart rate.
2. Carotid Point: The carotid pulse is taken by placing two fingers (usually the index and middle fingers) on the carotid artery, which is located on either side of the neck, just below the jawline. Again, you can count the number of beats per minute to determine the heart rate.
Both methods are commonly used to measure heart rate, and they are easy to access and provide accurate results. However, it's essential to be gentle when taking a pulse to avoid putting excessive pressure on the arteries.
