Does the magnetic field really protect Earth from anything?
Space & NavigationAsked by: Jie Molemogi Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass. Can we survive without Earth’s magnetic field? If the magnetic field was weaker

Is partial solar eclipse dangerous?
Space & NavigationIt is extremely dangerous to look directly at the sun even during a solar eclipse. You should never attempt to observe a total, partial or annular eclipse with the naked eye. The safest technique for viewing a solar eclipse is indirect viewing. What happens if you look at a partial solar eclipse? But if you

Why is the maximum magnification of a light microscope 1500x?
Space & NavigationOptical microscopes are limited to ~1500x magnification because resolving the smallest visible details is limited to Rayleigh criterion (i.e. limited to diffraction). Where λ is wavelength in nm and NA is numerical aperture of the lens. Why is 1000x the maximum magnification for a light microscope? The maximum magnification power of optical microscopes is typically

In what direction is the directional derivative maximum?
Space & Navigationthe same direction∇ f ∇ f and the unit vector point in the same direction. What is the maximum directional derivative of a surface? Detailed Solution. Directional derivative: It gives the rate of change of scalar point function in a particular direction. The maximum magnitude of the directional derivative is the magnitude of the gradient.

How do you calculate distance in C++?
Space & Navigationdistance = sqrt( (x2 – x1) * (x2 – x1) + (y2 – y1) * (y2 – y1) ); How do you find the distance from a C? Video quote: Okay so pythagoras theorem according to pythagoras theorem distance D is equal to square root of x2 minus x1 whole square plus y2. Minus y1

Can you have a horizontal and slant asymptote?
Space & NavigationA graph can have both a vertical and a slant asymptote, but it CANNOT have both a horizontal and slant asymptote. You draw a slant asymptote on the graph by putting a dashed horizontal (left and right) line going through y = mx + b. Can a horizontal asymptote be slanted? A slant asymptote, just
