Answer:
The flow of energy from falling water to the steam is;
a) Mechanical → Mechanical → Electrical → Thermal → Thermal
Explanation:
1) Mechanical → Mechanical
The water in the pipe before it falls possesses potential energy which it converts into kinetic energy as it falls from height
2) Mechanical → Mechanical
The water falling from the pipe stream unto the turbine wheel transfers its kinetic (mechanical) energy due to its motion on to the turbine wheel to give the wheel rotational motion
3) Mechanical → Electrical
The kinetic (mechanical) energy from the rotating turbine wheel is converted into electrical energy in the electrical generator which transported through the electrical circuit
4) Electrical → Thermal
The electrical energy from the electric current is then converted into thermal energy as the current passes through the resistors in the heating filament
5) Thermal → Thermal
The heated filament transfers thermal energy to the the water in the beaker by conduction which raises the temperature of the water such that as the water acquires more thermal energy it turns into steam
Therefore, we have the flow of energy from the falling water to steam as follows;
1) Mechanical 2) Mechanical 3) Electrical 4) Thermal 5) Thermal
Answer:
The primary cause of rising SST levels worldwide is climate warming due to excessive amounts of greenhouse gases being released into the atmosphere. Heat from the warming atmosphere raises the temperature of the sea surface. ... Water expands as it warms and the increased volume causes sea level rise.

Answer:
8.46 N/C
Explanation:
Using Gauss law
Gauss's Law states that the electric flux through a surface is proportional to the net charge in the surface, and that the electric field E of a point charge Q at a distance r from the charge
Here, K is Coulomb's constant whose value is 
r = 0.43 + 0.106 = 0.536 m
Answer:
318.3 nm
Explanation:
We approximate the circular film as a cylinder of height h and radius, r. Its volume V = πr²h. Since this volume equals the volume of the oil drop, the height of the circular film is thus h = V/πr²
V = 10⁻¹⁰ m³ and r = 10 m
Substituting into h, we have
h = 10⁻¹⁰ m³/π(10)²
= 0.3183 × 10⁻¹² m
= 3183 × 10⁻⁹ m
= 318.3 nm
