2. Campo Eléctrico en un Punto: - Calcular la intensidad del campo eléctrico en un punto situado a 0,1 metros de una carg de \( 2 \mu \mathrm{C} \).

3. La intensidad del campo eléctrico se define como "la fuerza eléctrica por unidad de carga experimentada por una pequeña carga puntual positiva \( q \) ". ¿Por qué la carga de prueba se describe como "pequeña"? A. Porque los electrones son pequeños. B. Obedecer la ley de Coulomb para cargas puntuales. C. Para que el campo eléctrico no se distorsione. D. Para que la carga de prueba no ejerza fuerza sobre otras cargas de la región.

In a conductor, the opposition to alternating current is called "inductive reactance". True False

Question The skid marks for a car involved in an accident measured \( 150 \mathrm{ft} \). Use the formula \( s=\sqrt{24 d} \) to find the speed \( s \), in feet per second, of the car before the brakes were applied. Provide your answer below: feet per second

Question A helicopter flying at an altitude of 600 ft dropped a package to a lifeboat. Use the formula \( t=\frac{\sqrt{h}}{4} \) to find how many seconds it takes for the package to reach the lifeboat. Round your answer to the nearest tenth of a second. Provide your answer below: seconds

Julia lifts a raw egg and drops it from a height of 6.2 ft . After 0.25 s , the egg is falling at a speed of \( 2.45 \mathrm{~m} / \mathrm{s} \). After 0.50 s, the egg is falling at \( 4.90 \mathrm{~m} / \mathrm{s} \). a. Drop two objects side by side at the same time. Be careful. Make sure neither one will get affected by the air much, but make them significantly different weights. Maybe a small rock and your friend's phone. Make sure the bottoms start at the same height above the ground so they fall the same distance. Make sure you release them at the same time. (If you just THINK about this, you will be making the age-old mistake of trusting your guess/intuition without experimental validation.) Within experimental consistency, do they hit at significantly different times? (Repeat as needed to be sure.) b. Sketch and label the process described for the egg. (Three states!) c. What information is "implied"? What is "red herring" info.? d. Did the egg pick up more speed in the second 0.25 s than the first? Why? Would the egg travel farther the first 0.25 s or the second? Why?
