las sillas voladoras de la figura tienen las siguientes dimensiones. La longitud L=12m y la distancia "a" 4m. ¿Cual tendria que ser la velocidad tangencial de la silla para que la cuerda forme un angulo de 30º con la vertical? (la silla gira en un circulo horizontal)

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

The ph is the a. independent variable b. the dependent variable c. control group
