The graph shows the speed (magnitude of the speed) of a car traveling in a straight line as a function of time. The value of Vc is 12.00 m / s and the value of Vd is 21.00 m / s. Which of the following statements is true? The acceleration at t = 0.4 s is equal to the acceleration at t = 4.2 s. The speed change from 0 to 0.75 s is the same as from 3 to 6 s The change of speed from 1 to 1.5 s is the same as from 4.5 to 5.0 s The distance traveled from the time 1.0 s to the time 3.0 s is less than the distance traveled from the time 5.0 s to the time 6.0 s The distance traveled from time 0.0 s to time 1.0 s is equal to the distance traveled from time 3.0 s to time 5.0 s Calculate the distance traveled by the car from time 0.4 s to time 6 s.

The tail of the Earth's magnetic field is stretched by the
solar wind so that the north field is still pointing
moving away from the earth and the south field pointing towards the earth.
The magnetic field at that distance has a density value of
magnetic flux about 0.25 Gauss. The space is the same
medium on both sides of the magnetic field but the fields do not
they can exist that way without a current sheet. If
you assume...

Las placas cuadradas de un capacitor están paralelas y tienen un área de 2000 cm2. La distancia de separación entre las placas es de 1.00 cm y el capacitor esta conectado a una fuente de energia cuya diferencia en potencial es de 3000 V. Después de un tiempo se desconecta el capacitor de la fuente de energia y se inserta un material no conductivo (dieléctrico) que llena por completo el espacio entre las placas. Luego se observa que la diferencia...
