<span>Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.</span>
Answer:
We know that in the decay process the sum of molecular number as well as molecular weight should be constant.
The following three reaction are as follows
1 .
Alpha decay of parent nuclide
The molecular number of alpha particle is 2 and molecular weight is 4 g/mol.
2.
Beta decay of daughter nuclide
v is the neutrino emission,The charge on the beta particle is zero.
3.
Alpha decay

Explanation:
Answer:
[H3O+] = 0.00520 M
Explanation:
The dissociation of acetic acid in water is given by the equation;
CH3COOH + H2O<-------> H3O+ + CH3COO-
ka = [H+][C2H3O2-]/[HC2H3O2]
Ka = 1.8 x 10^-5
= x^2 / 0.150-x
x = [H3O+]= 0.00520 M
Answer:
20.05 seconds
Explanation:
Given that:
v² = u² + 2as
v = final velocity
u = initial velocity
a = acceleration
s = distance
a = negative acceleration = - 0.43
s = distance = 86.5
v = 0
0 - 2(0.43)(86.5) = u²
74.39 = v²
U = sqrt(74.39)
U = 8.6249
From ;
t = Time in seconds
t = (v - u) / a
t = (0 - 8.6249) / - 0.43
t = 20.057
