Answer:

Explanation:
GIVEN
diameter = 15 fm =
m
we use here energy conservation

there will be some initial kinetic energy but after collision kinetic energy will zero

on solving these equations we get kinetic energy initial
J ..............(i)
That is, the alpha particle must be fired with 35.33 MeV of kinetic energy. An alpha particle with charge q = 2 e
and gains kinetic energy K =e∆V ..........(ii)
by accelerating through a potential difference ∆V
Thus the alpha particle will
just reach the
nucleus after being accelerated through a potential difference ∆V
equating (i) and second equation we get
e∆V = 35.33 Me V

The atmosphere absorbs most of the solar RADIATION in the atmosphere, but not all which is how we still get sun burns. :)
C. Upper mantle is further supdivided near the surface of two zones: - Asthenosphere - mean density about 3.3 g/cc. Denser and hotter than lithosphere above.
Answer:
The weight of the potatoes is 735 Newtons.
Explanation:
The weight can be determine, by means of the following equation.
(1)
Where m is the mass of the object and g is the acceleration due to gravity
Therefore, equation 1 can be used:

But 1N = 1Kg.m/s^2

Hence, the weight of the potatoes is 735 Newtons.
The force of attraction is decreased
