How do you perform a risk assessment? Risk assessments can be daunting, but we’ve simplified the process into seven steps: Define your risk assessment methodology. Compile a list of your information assets. Identify threats and vulnerabilities. Evaluate risks. Mitigate the risks. Compile risk reports. Review, monitor and audit. How much does a security risk assessment […]
Which of the following is of the least importance for safety when planning a recreational outing?
Which of the following is of the least importance for safety when planning a recreational outing? Answer: Weather Condition of your house. Explanation: There are many safety precautions to consider when preparing for a recreational outing, among it are the weather if the destination, the amount of water you are going with, the equipment and […]
How is Miss penalty calculated in cache?
What is the difference between Butterworth Chebyshev I and Chebyshev II filters?
What is the difference between Butterworth Chebyshev I and Chebyshev II filters? Butterworth filter has a poor roll-off rate. For the same filter order, the stopband attenuation is higher for the Chebyshev filter. Compared to a Butterworth filter, a Chebyshev-I filter can achieve a sharper transition between the passband and the stopband with a lower […]
What does not affect stopping distance?
What does not affect stopping distance? Visibility is one of a number of factors that do not affect your braking distance per se but can inhibit your thinking distance. The longer it takes for you to spot hazards in the road, the more time will have passed before you hit the brake pedal. What will […]
What happens to the workpiece if the cutting tool is dull?
What happens to the workpiece if the cutting tool is dull? There are many effects of performing a cutting operation with a dull tool. Note that a dull tool has an increased tip radius (see Fig. 21.22 on p. 636); as the tip radius increases (the tool dulls), the cutting force increases due to the […]
Which of the following quenching media is most severe in its quenching action?
Which of the following quenching media is most severe in its quenching action? Different quenching media have different degrees of severity. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. Which quenching media gives the fastest cooling? Brine. Brine is a mixture of water and salt. Brine cools faster than […]
How do you check exhaust gas recirculation?
How do you check exhaust gas recirculation? A vacuum-controlled EGR valve is easy to test with a hand-held vacuum pump (see the image). If the EGR valve opens and the vacuum holds for more than a minute, the EGR valve works. If a vacuum diaphragm inside the EGR valve is leaking, the vacuum will drop. […]
Is drag equal to weight?
Is drag equal to weight? When drag is equal to weight, there is no net external force on the object and the vertical acceleration goes to zero. With no acceleration, the object falls at a constant velocity as described by Newton’s first law of motion. Which reaches terminal velocity first? Both elephant and feather weigh […]
Does thermal conductivity depend on temperature?
Does thermal conductivity depend on temperature? The effect of temperature on thermal conductivity is different for metals and nonmetals. In metals, heat conductivity is primarily due to free electrons. In alloys the change in electrical conductivity is usually smaller and thus thermal conductivity increases with temperature, often proportionally to temperature. What is the temperature dependence […]
