Why is there a puddle under my car? The best thing you can do if you’re finding puddles of liquid under your car is to determine what the liquid is: The 3 most common types would be: Water: if it’s water, and you know you’ve been running the air conditioner or interior heater, it’s likely […]
What are the steps to draw Lewis structures?
When was the rocket engine invented?
When was the rocket engine invented? M Who invented the first rocket engine? Konstantin Tsiolkovsky Why does NASA use countdowns? Countdown clocks allow technicians and astronauts to synchronize their moves throughout a rocket launch sequence, from T-minus 43 hours all the way until the final ignition. The clock also serves as the visual version of […]
What is the function of low pass filter?
What is the function of low pass filter? A low-pass filter (LPF) is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. How many dB is a watt? […]
What happens when a preferred stock is called?
What happens when a preferred stock is called? A callable preferred stock issue offers the flexibility to lower the issuer’s cost of capital if interest rates decline or if it can issue preferred stock later at a lower dividend rate. The proceeds from the new issue can be used to redeem the 7% shares, resulting […]
What is viscoelastic creep?
What is viscoelastic creep? Viscoelastic creep When subjected to a step constant stress, viscoelastic materials experience a time-dependent increase in strain. This phenomenon is known as viscoelastic creep. At time , a viscoelastic material is loaded with a constant stress that is maintained for a sufficiently long time period. What is creep and stress relaxation? […]
How does a resistor affect voltage?
How does a resistor affect voltage? The larger the resistor, the more energy used by that resistor, and the bigger the voltage drop across that resistor. Also, Kirchhoff’s circuit laws state that in any DC circuit, the sum of the voltage drops across each component of the circuit is equal to the supply voltage. What […]
Do natural gas furnaces need a chimney?
Do natural gas furnaces need a chimney? But here’s a piece of interesting news: you may not need a chimney at all. Today’s gas furnaces operate super-efficiently, so they use an entirely different type of furnace venting system. Here’s how it works and what options you have if you choose to forego chimney repairs. Can […]
Which gas has highest diffusion rate?
Which gas has highest diffusion rate? Diffusion is inversely proportional to molecular weight. Therefore, NH3 has the highest diffusion rate. Which noble gas diffuses the fastest? Neon Why rate of diffusion is faster in gases? Diffusion is driven by differences in concentration. When chemical substances such as perfume are let loose in a room, their […]
What is filter in circuit theory?
What is filter in circuit theory? A filter is a circuit whose transfer function, that is the ratio of its output to its input, depends upon frequency. There are three broad categories of filter which are widely used: Low-pass filters allow any input at a frequency below a characteristic frequency to pass to its output […]
