1. A(n) is an image of a distant object caused by light refraction through air of varying temperature.

2. A(n) is a curved piece of glass or other transparent substance that is used to refract light.

3. A(n) lens is thicker in the center than at the edges.

4. A(n) lens is thinner in the center than at the edges.

5. The is a measure of how much a ray of light bends when it passes from one medium into another.

Ahowler monkey is the loudest land animal and, under some circumstances, can be heard up to a distance of 4.6 km. assume the acoustic output of a howler to be uniform in all directions and that the threshold of hearing is 1.0 × 10-12 w/m2. what is the acoustic power emitted by the howler

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?
