Answer:
intrinsic semiconductors
Explanation:
An intrinsic semiconductor is also known as a pure conductor. In such a semiconductor there are no impurities, that is why it is said to be pure.
It has some of these properties:
1. Electrical conductivity is only based on temperature
2. The quantity of electrons is the same as the number of holes in the valence bond
3. Electrical conductivity is not on the high side
4. These materials exist in their pure forms.
Answer:
1. Make sure the regulator adjustment screws are completely backed out and loose.
2. Open the main cylinder valves slowly.
3. Set the Oxygen and Acetylene working pressures.
4. Light and adjust the torch.

Answer:
Explanation:
This is the broadened and extended part of the floor and also generally rests on the foundation piles, which are made of seasoned bamboo or wood driven at 0.3 m intervals into the soft soil with the butt end up. The apron serves as protection to scouring and future seepage of water at the gate's sides.
Answer:
The chronic daily intake is 0.0328608 mg/kg day
Explanation:
The CDI due to ingestion is equal to:
Where
C = concentration = 1 mg/L
IR = 2.3 L/day
ED = risk dying per year = 70 year
EF = number of days per year = 365 days
AT = average tenure time = 75 year
BW = weight of body = 65.4 kg
The ingestion rate is:
IR = 20/60 = 0.333 h/day
The CDI due to dermal contact is equal to:
The CDI due to inhalation is equal to:
The total is:
CDItotal = 0.0328 + 5.41x10⁻⁵ + 6.7x10⁻⁶ = 0.0328608 mg/kgday
