The sun consists of about 70% hydrogen, 28% helium, 1.5% carbon, nitrogen and oxygen, and 0.5% all other elements. Additionally, the sun's mass is decreasing every second as it fuses 610 million metric tons of hydrogen into 606 million metric tons of helium each second for a loss of 4 million metric tons per second.</span>
Because the alpha particles were passing through the foil with slight to no reflection however some alpha particles were deflected with high angle or reversed direction which is not what was expected as according to thomson the atom is a lump of postively charged mass and there will be no deflection as the charge is distrbuted and the charge of alpha particle is 207 times that of electron
Answer:
power is - 1.25 D
focal length is 0.429 m
power is 2.33 D
Explanation:
given data
near point = 25.0 cm
far point q = 80.0 cm
to find out
What type and focal length for far point = 80.0 cm and near point = 60.0 cm away
solution
we apply here lens formula for concave lens
1/f = 1/p + 1/q
here we know p is infinity because near sight and q is negative i.e -80
1/f = 0 - 1/80
f = -80 cm
and power = 1/f
power = 1/80 = 0.0125 
power = - 1.25 D
and
for far sight convex lens formula use
1/f = 1/p + 1/q
here p is 25 and q = -60
so 1/f = 1/25 - 1/60
1/f = 0.02333 
f = 42.863 cm = 0.429 m
power = 1/f = 2.33 D
