- This was somewhat helpful, but my radius is not 3.5km it's 5km. This is not the answer to my question, it is only similar to it. I can not interpret your handwriting to follow along to answer for my question.I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.Give the names of two length units that are longer than a metre. What is their connection to the metre?
- How do we measurementWhy is the phrase “scientific proof” somewhat misleading?In he vacuum of space, the speed of light (c) is 3 X 105 km/s and 1 km = 1,000 = 10³ m. Using V = c = fA, what is the wavelength in meters of a light wave with a frequency of 1012 Hz? First convert c to units of meters/second (m/c). Then substitute into the wave equation.
