A small source of light Sis located at a distance Lfrom a vertical wall. An opaque object with a height of h moves toward the wall with constant velocityv_vec of magnitude v. At time t= 0 , the object is located at the source S. Find an expression for v_s, the magnitude of the velocity v_s_vec of the top of the object's shadow, at time t.

Express the speed of the top of theobject's shadow in terms of t, v,L, and h.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
