You are given an unknown source, which produces spectral lines. is it possible to determine the wavelengths of these spectral lines? if so, how? explain in words.

when it gains or loses electrons

which three statements are true about all alloys?

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
