False; the three major scales used to measure earthquakes are the Mercalli Scale, the Richter Scale, and the Magnitude Scale. I hope this helps!
Answer:2.517 J/K
Explanation:
Given
Reservoir 1 Temperature 
Reservoir 2 Temperature 
Let Q is the amount of heat Flows i.e. 
thus change in Entropy is given by 



1.Life science involves fields of discipline catering to living organisms such as we humans while physical science caters to non-living organisms.
2.Life science has more fields of discipline than physical science.
3.Physical science relies on laws and theories to explain concepts while life science relies on biological explanations and can also rely on theories.

Explanation:
A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.
- A battery is made up of two electrodes which are the cathode and anode.
- The cathode is the positive electrode and the anode is the negative one.
- These electrodes are made up of metals.
- Electrons moves from the anode to the cathode and current flows from cathode to anode.
- At the anode oxidation occurs because electrons are produced here.
- It needs to have low electron affinity.
- At the cathode where reduction occurs, the electron affinity must be high.
- This is the driving force for the production of electricity in electrochemical cells.

Complete question:
A solenoid that is 98.6 cm long has a cross-sectional area of 24.3 cm2. There are 1310 turns of a wire carrying a current of 6.75 A. (a) Calculate the energy density of the magnetic field inside the solenoid. (b) Find the total energy stored in the magnetic field there (neglect end effects).
Answer:
(a) the energy density of the magnetic field inside the solenoid is 50.53 J/m³
(b) the total energy stored in the magnetic field is 0.121 J
Explanation:
Given;
length of the solenoid, L = 98.6 cm = 0.986 m
cross-sectional area of the solenoid, A = 24.3 cm² = 24.3 x 10⁻⁴ m²
number of turns of the solenoid, N = 1310 turns
The magnitude of the magnetic field inside the solenoid is given by;
B = μ₀nI
B = μ₀(N/L)I
Where;
μ₀ is permeability of free space, = 4π x 10⁻⁷ m/A

(a) Calculate the energy density of the magnetic field inside the solenoid

(b) Find the total energy stored in the magnetic field
U = uV
U = u (AL)
U = 50.53 (24.3 x 10⁻⁴ x 0.986)
U = 0.121 J
