To solve this problem it is necessary to apply an energy balance equation in each of the states to assess what their respective relationship is.
By definition the energy balance is simply given by the change between the two states:

Our states are given by



In this way the energy balance for the states would be given by,



Therefore the states of energy would be
Lowest : 0.9eV
Middle :7.5eV
Highest: 8.4eV
The guy below is wrong!
F=ma
Where force = mass x acceleration
We dont have acceleration, a= change in velocity divided by the time taken.
a = v (final velocity) - u (initial) / t
a us 8-0 (at rest means u was 0) / 20 = 0.4
Using F=ma
F= mass x acceleration
F= 4 x 0.4
F=1.6 N
It is the point in a black hole where nothing, not even light, can escape from.
<span>F = GMm/r^2
but we don't want force we want acceleration.
F = ma
combining the two
ma = GMm/r^2
cancelling m from both sides
a = GM/r^2
where G is the universal gravitational constant M is the mass of Saturn and r is the radius of Saturn.
g(Saturn) = a = (6.67x10^-11m^3kg^-1s^-2)(5.68x10^26 kg)/(5.82x10^7m)^2
g = 11.18 m/s^2 round to 11.2 m/s^2</span>
Answer:
he diameter of the oil slick is 2523 m
Explanation:
given information?
V = 1 L = 1000 cm³ = 0.001 m³
h = 2 x 10⁻¹⁰ m
first we have to find the radius using the following equation
V = πr²h
r = √V/(πh)
= √(0.001)/(π x 2 x 10⁻¹⁰ )
= 1261.56 m
now, we can calculate the diameter of the oil slick
d = 2r
= 2 (1261.56)
= 2523 m
