Si el campo gravitatorio en un punto vale 25m/s², calcula la fuerza gravitatoria que actúa sobre una masa de 12kg colocada en ese punto.

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

What you see with your eyes is a form of energy. a. light b. heat c. chemical d. electrical

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
