Copper has a breaking stress of about 3 × 10^8 N/m^2. A. Illustrate what is the maximum load that can be hung from a copper wire of diameter 0.46 mm? Answer in units of N B. If 30% of this maximum load is hung from the copper wire, by what percentage of its length will it stretch? Answer in units of %.
A charge of -4 nC is at the origin and a second charge of 14 nC is at x = 3.00 m. Find out the magnitude and direction of the electric field halfway in between two charges.
An explosion breaks an object into two pieces, one of which has 1.80 times the mass of the other. If 10000 J were released in explosion, how much kinetic energy did each piece acquire.
Compute the ground state energy and wavefunction
Object A, which has been charged to + 29.2 nC, is at the origin. Object B, which has been charged to - 28.9 nC, is at ( x,y ) = ( 0.0;{rm cm},; 1.50 cm ).What is the y-component of force (vec{F}_{rm A ; on ; B})_{rm y} on B due to A.
