What shape is a sine wave? A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero. What are 3 types of progressive waves? 8.1) Compare […]
How do you graph velocity vs acceleration?
How do you graph velocity vs acceleration? If the graph is velocity vs time, then finding the area will give you displacement, because velocity = displacement / time. If the graph is acceleration vs time, then finding the area gives you change in velocity, because acceleration = change in velocity / time. How do you […]
Why shouldnt you drink tea on an empty stomach?
Why shouldnt you drink tea on an empty stomach? Apart from being one of the top causes of acidity, morning tea can result in washing out of bacteria right from your mouth to your gut. In the gut, it interferes with good bacteria, and might disrupt your metabolism and upset stomach. Why we should not […]
What are the four main ergonomic risk factors?
What are the four main ergonomic risk factors? Ergonomic risk factors are workplace situations that cause wear and tear on the body and can cause injury. These include repetition, awkward posture, forceful motion, stationary position, direct pressure, vibration, extreme temperature, noise, and work stress. What are the 5 of the 6 risk factors associated with […]
Can pumps be used for gas?
Can pumps be used for gas? Pumps have the ability to move liquids or gases. Compressors typically only move gas due to its natural ability to be compressed. Which pump is used for crude oil? Centrifugal pumps What is the difference between pump and turbine? A pump absorbs useful energy and converts it to kinetic […]
Why is an alternator better than a dynamo?
Why is an alternator better than a dynamo? An alternator is a device that generates AC power from the rotation of an axle (mechanical energy). They are a bit similar to dynamos, but differ in the fact that they make AC power, whereas dynamo’s generate DC power. In addition, they also tend to be more […]
How do you know if a graph is Hamiltonian?
Should I sign up for Medicare Part A if I am still working?
Can I replace a LED with a diode?
Can I replace a LED with a diode? Practically, LED can not be used as diodes. Reverse voltage rating (PIV rating) of LEDs is less than 5-10 volts, which is not enough for most of the applications. 2. Reverse leakage current even for low reverse voltages (less than 5-10 volts) is too large for LEDs. […]
Does height affect acceleration due to gravity?
Does height affect acceleration due to gravity? The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth. Which force would cause an […]
