Applying Kirchoff's junction rule; the power source and current split when the parallel circuit has two branches.
Discussion:
This forms a basis for the Kirchoff's Junction rule.
In a circuit of resistors; a parallel arrangement of the resistors leaves the current divided in a ratio according to the resistance of the resistors.
However, the case is not the same for a series connection

Answer:
The observed wavelength on Earth from that hydrogen atom is .
Explanation:
Given that,
The actual wavelength of the hydrogen atom,
A hydrogen atom in a galaxy moving with a speed of,
We need to find the observed wavelength on Earth from that hydrogen atom. The speed of galaxy is given by :
is the observed wavelength
So, the observed wavelength on Earth from that hydrogen atom is . Hence, this is the required solution.
Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic. Magnetic moments<span> come from the moments of all of its </span>atoms<span>.</span>
Acceleration = velocity / time.
Answer:
accleraion normal ski 0.0735 m/s², new ski 0.219 m/s²
Explanation:
This exercise should work with the one-dimensional kinetic equations, specifically with the equation
x = v₀ t + ½ a t²
When the skier is at the exit they are at rest, so their initial speed is zero
(v₀ = 0)
x = ½ a t²
Let's calculate the acceleration for normal skiing
a₁ = 2 x / t²
a₁ = 2 175/69²
a₁ = 0.0735 m/s²
a₁ = 7.35 10⁻² m/s²
Let's calculate the acceleration with the new plastic ski
a₂ = 2 x / t₂²
a₂ = 2 175/40²
a₂ = 0.219 m/s²
a₂= 2.19 10⁻¹ m/s²
