Un campo magnético entre los polos de un imán en forma de U es 0.0006 T, si una carga positiva de 3,2x10-19C se mueve con velocidad de 10^5 m/sen dirección perpendicular al campo, calcule la fuerza magnética que experimenta la carga.

0.11 m/s and 0.28 m/s should be correct

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
