Radial acceleration is = v^2/r
Therefore (8.8m/s)^2/(25m)= 3.10m/s^2
Hope this helps you! Any questions please just ask! Thank you!
Answer:
0.00073
Explanation:
= Fraction of atoms of the element in the excited state
= Fraction of states
T = Temperature = 4471 K
h = Planck's constant =
= Boltzmann constant =
= Wavelength = 407.3 nm
We have the relation
Change in energy is given by
The fraction of atoms of the element in the excited state is 0.00073
The current density of the copper wire is determined as (7.059 x 10⁸ A/m²)/L
<h3>Current density of the copper wire</h3>
The current density of the copper wire is calculated as follows;
J =1/ρ(E) = 1/ρ(V/L)
where;
- E is electric field
- V is voltage
- L is length of the wire
<h3>Current density the wire</h3>
J =1/ρ(E) = 1/ρ(V/L)
J = (1/1.7 x 10⁻⁸) x (12)/L
J = (7.059 x 10⁸ A/m²)/L
