How do electromagnetic fields affect the human body? Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes. How does frequency affect the human […]
How do I know if my steering rack is part of routine maintenance?
How do I know if my steering rack is part of routine maintenance? Checking the steering box A typical steering-box layout. Check the gasket and seals for leaks, and the moving parts for wear. Measure steering-wheel travel by making a chalk mark on the rim and using your finger as a reference point. Try to […]
Why are batteries called AA?
Why are batteries called AA? But the most significant difference is size because batteries are called AA & AAA because of their size and dimension. AA doesn’t stand for anything. It is simply an identifier for a battery of given dimensions and nominal voltage. Are C batteries the same as AA? AA batteries are the […]
What is a solubility graph?
What is a solubility graph? A solubility graph is drawn to display the solubility at different temperatures. From reading a solubility graph, one can determine the mass of solute that can dissolve at specific temperatures, whether or not a solution is saturated, and compare solubilities of different substances at specific temperatures. Which of the following […]
Why does a hollow sphere have more rotational kinetic energy?
Why does a hollow sphere have more rotational kinetic energy? Another hollow sphere of the same mass and radius is rotating about its axis through the center at the same rotation rate. Which sphere has a greater rotational kinetic energy? The hollow sphere, since the mass is distributed further away from the rotation axis. Does […]
What caused the Izmir earthquake 2020?
What caused the Izmir earthquake 2020? The magnitude 7.0 tremor occurred in an area of complex geological movement, where multiple tectonic plates crack the surface as they jostle for position. Rescue workers and locals search for residents trapped in the debris of a collapsed building in Izmir, Turkey, on October 30, 2020. Why did the […]
What is the Y intercept when given two points?
What is the Y intercept when given two points? Steps Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11) Substitute the slope(m) in the slope-intercept form of the equation. Substitute either point into the equation. You can use either (3,5) or(6,11). Solve for b, which is the y-intercept […]
Why is a decrease in GDP bad?
Why is a decrease in GDP bad? When GDP goes up, the economy is generally thought to be doing well. Meanwhile, weak growth signals that the economy is doing poorly. If GDP falls from one quarter to the next then growth is negative. This often brings with it falling incomes, lower consumption and job cuts. […]
How do you shift focus while filming?
How do you shift focus while filming? How to pull focus on your mirrorless camera or DLSR Switch your cameras exposure to video and manual exposure. Switch your lens to manual focus. Open the aperture as wide as it will go. Set the shutter speed for 2x framerate. Adjust the ISO to correct the exposure. […]
What is the relation between current and resistance?
What is the relation between current and resistance? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is a specific resistance? […]
