An object is situated 40cm from a convex mirror. When a plane mirror is inserted between object and convex mirror at a distance of 32 cm from the objects, the images in the two mirror coincide. What is the focal length of the convex mirror ​

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
