Copernicus's model of the universe differs from Ptolemy's because Copernicus believed
Answer:
Inertia : a property of matter by which it continue in its existing state of rest or uniform motion in a straight line, unless that state is changed by external force.
HOPE ITS HELPS!!
when two vectors are inclined at some angle to each other then the magnitude of resultant of two vectors is given as
![R = \sqrt{A^2 + B^2 + 2AB cos\theta}](https://tex.z-dn.net/?f=R%20%3D%20%5Csqrt%7BA%5E2%20%2B%20B%5E2%20%2B%202AB%20cos%5Ctheta%7D)
here A and B are the magnitude of two vectors and theta is the angle between them
now here we know that two vectors are of magnitude 0.25 m/s^2 each and they are inclined at angle of 45 degree
now we will plug in all data above
A = B = 0.25
![\theta = 45](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2045)
![a_{net} = \sqrt{0.25^2 + 0.25^2 + 2*(0.25)(0.25)cos45}](https://tex.z-dn.net/?f=a_%7Bnet%7D%20%3D%20%5Csqrt%7B0.25%5E2%20%2B%200.25%5E2%20%2B%202%2A%280.25%29%280.25%29cos45%7D)
![a_{net} = 0.46 m/s^2](https://tex.z-dn.net/?f=a_%7Bnet%7D%20%3D%200.46%20m%2Fs%5E2)
So the magnitude of resultant acceleration will be 0.46 m/s^2
