How do electromagnetic fields affect the human body?
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? 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 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 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 […]
What are emission spectrums used for?
What are emission spectrums used for? A spectroscope can be used to determine which frequencies have been emitted by a substance. The emission spectrum is a combination of the atomic spectra of the various kinds of atoms making up the substance and can be analyzed to determine the substance’s chemical or atomic composition. What do […]
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. […]
