Answer:
option C
option A
Explanation:
Enthalpy gained by air= 1023-290
= 733 kJ/kg
Rate of energy gain= mass flow rate × Enthalpy gained by air
= 0.1 × 733
= 73.3 kJ/s
rate of heat transfer between compressor and air= 77kW
Heat loss by air to surroundings= 77-73.3
=3.7kW
Enthalpy lost by steam in turbine= 1407.6-1236.4
= 171.2 Btu/lb
Rate of energy transfer to turbine= Enthalpy lost by steam× mass flow rate
= 171.2×5
= 856 Btu/s
Net rate of energy transfer to turbine=rate of Energy transfer to turbine- rate of heat transfer to turbine
= 856-40
= 816 Btu/s
Most of our knowledge about Earth's interior comes from Seismic waves. Thus, option C is correct.
<h3>What is seismic waves</h3>
Seismic waves are created by abrupt movement of elements within the Earth, including fault rupture during an earthquake. Seismic waves can be caused by volcanic eruptions, blasts, landslides, rock slides, and even flowing rivers.
Seismic waves, also known as compressional or longitudinal waves, push and pull the earth in the direction of motion. Seismic waves provide the majority of our information about the Earth's innards. As a result, option C is correct.

Answer:
Technician A
Explanation:
The Battery Council International (BCI) battery group numbers is an industry standard for batteries that indicate two important this;
- Physical size of a car battery which are; height , width and length.
- Polarity on the battery which is the location of the positive and negative battery posts
For example : a group 24 battery or a type 27 marine battery are battery group numbers that define the physical dimensions of a battery case. These numbers are important because car owners and manufacturers use the numbers <em>to match vehicle power requirements with the alternators </em>.A mismatch of the battery and the alternator can cause the vehicle's alternator to overheat leading to a short life span.
<u>Technician A statement is correct.</u>
