As solar wind approaches Earth, what happens to the charged electrons?
They are deflected as Earth’s magnetic field exerts force on them.
Which best describes how energy transferred from an electron in the solar wind compares with energy absorbed by an electron in the oxygen atom?
equal to
Which statement is accurate about how the aurora borealis is formed?
When the electrons fall to a lower energy state, they release energy as electromagnetic radiation, light.
How does the energy in the light of the aurora borealis compare to the energy as an excited electron returns to its original energy level?
equal to
During the formation of the aurora borealis, the electrons in an atom experience a change in energy levels. Which statement about this change is accurate?
First, the electron absorbs energy to move to a higher energy level.
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:
simplify by 2
Answer:
B.) 1/2 cm

Period of an ideal simple pendulum = 2π √(L / G)
1.87 = 2π √ (L / 9.81)
Divide each side by 2π : (1.87 / 2π) = √ (L / 9.81)
Square each side: (1.87 / 2π)² = L / 9.81
Multiply each side by 9.81 : L = (9.81) (1.87 / 2π)² = <em> 0.869 meter</em>
Choice 'D' is the closest one.
