Discrepancies are sometimes observed between theoretical and actual metal removal rates and electrode feed rates.

Discrepancies are sometimes observed between theoretical and actual metal removal rates and electrode feed rates. Correct Answer True

In practise, metal removal rates are often higher than the estimated ones because; (1) The exact valency at which a metal behaves in the reaction is generally unknown. (2) ECM continuously exposes a new and clean surface to the electrolyte which is easily attacked chemically. It also varies with electrolyte used and metal being machined.

Given below are four jumbled sentences. Select the option that gives their correct order. Interest rates, in turn, are a crucial determinant of how much firms and consumers want to spend. Conversely, a consumer may be lured into buying a new home if interest rates are low and mortgage payments are therefore more affordable. A firm faced with high-interest rates may decide to postpone building a new factory because the cost of borrowing is so high. The Federal Reserve System strongly influences the size and growth rate of the money stock, and thus the level of interest rates in the economy.
After GST and demonetisation, rising interest rates are set to hurt SMEs. Interest rates for loans against property (LAP) extended to small and medium sized enterprises (SMEs) are set to rise in the coming months of 2018 ‘ Rising interest rates, in addition to the muted operating environment for small businesses in India, will lead to an increase in delinquencies on LAP extended to SMEs’. The introduction of the goods and services tax (GST) in July 2017 and the government's demonetization policy have placed stress on the SME sector, which rising interest rates will exacerbate. Which of the following can be logically inferred from the statement above?
