Un electrón se mueve a 7x10^6 m/s en dirección horizontal. Este ingresa en un campo eléctrico vertical uniforme de -7,3x10^3 N/C. Haga un esquema del problema y encuentre el tiempo que tarda el electrón en viajar 3 cm en forma horizontal y su desplazamiento vertical después de haber recorrido esos 3cm en la horizontal. Ignore los efectos gravitacionales.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
