Consider the image here where one wave with blue dots meets up with another wave with red dots. If each grid represents 1 cm in both the x and y axis, what is the wavelength of the blue dotted wave?

Describe the path of a ray that approaches a mirror parallel to the principal axis.

How much force must a locomotive exert on a 12840-kg boxcar to make it accelerate forward at 0.490 m/s2?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
