Explanation

The Northern Hemisphere is warming faster than the Southern Hemisphere.

Due to more landmass and higher population density.

It leading to increased carbon emissions and heat retention.

Explanation

An electric circuit is a closed path through which electric current flows.

It enabling the transfer of electrical energy.

Electric current is measured in amperes using an ammeter.

Explanation

Kirchhoff's Voltage Rule (KVL) states that the sum of potential differences (voltages) in a closed loop is zero.

This is based on the conservation of energy, as energy gained equals energy lost in a loop.

Explanation

To find the work function, we need to calculate the energy of the photon (E) and the kinetic energy of the electron (KE), then use the equation:

φ = E - KE

E = hc / λ = 1240 eV nm / 4000 nm = 3.1 eV

KE = (1/2)mv^2 ≈ (1/2) × 9.11 × 10^-31 kg × (6 × 10^5 m/s)^2 ≈ 1.64 × 10^-19 J ≈ 1.024 eV

φ = 3.1 eV - 1.024 eV ≈ 2.076 eV ≈ 2.1 eV
