¿Qué describe la ley de Coulomb propuesta por el fisico francés Charles Augustin de Coulomb para el año de 1785 ?

The force needed to keep a car from skidding on a curve varies Inversely as the radius of the curve and jointly as the weight of th car's speed. Suppose that 200 pounds of force keeps a 3200 -pound car from skidding on a curve of radius 400 ft at 25 mph . What car from skidding on a curve of radius 550 ft at 55 mph ? pounds of force

El agua en el interior de una manguera se comporta aproximadament como un fluido ideal. Considerando que la manguera cuenta con un diámetro interno de 2 cm , por la que fluye agua a \( 0,5 \mathrm{~m} / \mathrm{s} \). Calcula el caudal que sale por la manguera

\( vf=vo^{2}+2.a.d \)

The brightness of a light bulb changes inversely with resistance and directly with voltage. What is the new resistance if a 60 -watt, 120 -volt bulb is used in place of a 100 -watt, 120 -volt bulb with 144 ohms?
