Two identical small conducting spheres are separated : Two identical small conducting spheres are separated by 0.60m. The spheres carry dissimilar amounts of charge and each sphere experiences an attractive electric force of 10.8N. The total charge on the two spheres is -24uC. The two spheres are now con..

Certain natural forms of potassium have nuclei : Certain natural forms of potassium have nuclei that are radioactive. Each radioactive potassium nucleus decays to a slightly less massive daughter nucleus and a high-speed electron called a beta particle.

Decide the direction of the velocity of the two vehicles : A 1220kg car traveling south at 24 m/s with respect to the ground collides with and attaches to a 2410kg delivery truck traveling east at 16 m/s. Decide the direction of the velocity of the two vehicles when locked together just after the collision. ..

Meteorite exerted on earth through the collision : About 65 million years ago a 10-km-diameter 2×1015kg meteorite traveling at about 10 km/s crashed into what is now the Gulf of Mexico. The impact produced a cloud of debris that darkened Earth and led to the extinction of the dinosaurs. Discover the ..

What is the degeneracy of the level : Consider a particle in a cubic box (side =L). By analogy to the particle in the 2D box, write down the expressions for the Psi(x, y, z) and E. What is the degeneracy of the level that has energy three times that of the lowest level?

A certain soil has a monochromatic absorptivity : A certain soil has a monochromatic absorptivity of 0.91 at a wavelength of 5 micrometers. What will its monochromatic remittance at lambda=15 micrometers be if it's temperature is 290 K and it can be assumed to be a grey body?

What is the radius of flight path at start of the pullout : The jet plane is diving at a speed of 866 km/h when the pilot starts an 8g pullout. The weight of the airplane is 71172N. Suppose that the engine thrust and total airplane drag are equal, opposite and collinear. What is the radius of flight path at s..
