Hola ayuda Por favor 1- Calcule la presión que ejerce un disco circular de plástico que se encuentra flotando sobre la superficie del agua de una piscina. El disco tiene un diámetro de 1,5 m y posee una masa de 6 kg.

2- Calcule la densidad de un líquido que se encuentra contenido en un tanque cilíndrico, si se sabe que el recipiente tiene una base de 1.2 m de diámetro y que el líquido tiene una masa de 5 kg. Además, la altura de la columna de líquido es de 1,3 m.

Apoint charge +q is at the origin. a spherical gaussian surface centered at the origin encloses +q. so does a cubical surface centered at the origin and with edges parallel to the axes. select "true" or "false" for each statement below. the electric flux through the spherical surface is greater than that through the cubical surface. suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. the flux through both surfaces remains unchanged. the area vector and the e-field vector point in the same direction for all points on the spherical surface. the e-field at all points on the spherical surface is equal due to spherical symmetry. the flux through the spherical gaussian surface is independent of its radius.
