Answer:
Option B
Explanation:
An operational amplifier usually has a high open loop gain of around 10^5 which allows a wide range get of feed back levels in order to achieve the desired performance so therefore a low open loop gain reduces the range feed back level thereby reducing the performance which can cause errors in the output voltage.

2. It needs leveling.
Answer:
True.
Explanation:
A product life cycle can be defined as the stages or phases that a particular product passes through, from the period it was introduced into the market to the period when it is eventually removed from the market.
Generally, there are four (4) stages in the product-life cycle;
1. Introduction.
2. Growth.
3. Maturity.
4. Decline.
Life cycle assessment (LCA) also known as life cycle analysis can be defined as an environmental management technique which is typically used by industries to assess, monitor and analyze the impact of the various stages of the life-cycle of their products, systems, processes or activities and services on the environment i.e the cradle to grave impacts.
Generally, life cycle assessments requires a thorough evaluation of the raw materials and energy that are being used in the manufacturing process of a product or service, as well as determining the various emissions into the environment respectively.
For example, in the manufacturing process of a product, life cycle assessment evaluates the impact of the product from raw material extraction (cradle) to production (finished product), distribution, use, and the disposal of the product (grave).
Hence, life cycle assessments are used by various industries to identify and evaluate the total energy impacts of their products and services.
The magnitude of applied stress in the direction of 101 is 12.25 MPA and in the direction of 011, it is not defined.
Explanation:
Given:
tensile stress is applied parallel to the [100] direction
Shear stress is 0.5 MPA.
To calculate:
The magnitude of applied stress in the direction of [101] and [011].
Formula:
zcr=σ cosФ cosλ
Solution:
For in the direction of 101
cosλ = (1)(1)+(0)(0)+(0)(1)/√(1)(2)
cos λ = 1/√2
The magnitude of stress in the direction of 101 is 12.25 MPA
In the direction of 011
We have an angle between 100 and 011
cosλ = (1)(0)+(0)(-1)+(0)(1)/√(1)(2)
cosλ = 0
Therefore the magnitude of stress to cause a slip in the direction of 011 is not defined.
