Homework EquationsThe Attempt at a Solution
2sin3x=1 OR 2sin3x= -1
sin3x=1/2 sin3x= -1/2
From the unit circle and in accordance with the domain
there are 3 solutions (B)
But the answer is (C)
HOW?
Sorry about that, those were typos, fixed them up now, also i understood the notion that we were finding the mass of one photon, but how would i mathematically solve it
thanks
Hi, stuck on this question, hoping someone could help
1. Homework Statement
Two identical photons of wavelength 4.22x16^-7m are created when a certain amount of matter M, is converted into energy, calculate the Mass (M)
The Attempt at a Solution
E= hf which is hc/wavelength
E= 4.71x10^-19J...
So does this mean I consider gravity of Earth as my centripetal velocity and therefore:
g= GM/r^2, but i still have a query, if you could kindly clear this up for me, why can't we use the centripetal formula in this question.
Homework Statement
Hi, I am stuck on this question:
A satellite of mass 1200 kg is in orbit around the Earth at a distance of 22000 km from the centre of the Earth.
Calculate the magnitude of the centripetal acceleration of the satellite at this distance.
The Attempt at a Solution
I did...
