An optical technician mounts two thin lenses along a single optical axis (the lenses are at right angles to the line connecting them, and they appear concentric when viewed from either end). The lenses are identical, each with a positive (converging) focal length of +15.2 cm. They are separated by a distance of 40.1 cm. Lens 1 is to the left of Lens 2
In order to evaluate the lens combination as a single optical instrument, the student places an object 30.0 cm in front of (to the left of) Lens 1.
(a) What is the final image's distance (in cm) from Lens 2?
(b) Where is the final image located?
(c) What is the overall magnification of the lens pair, considered as a single optical instrument?

a straight line sloped

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

the given statement is true.

sensory memory lasts for a fraction of seconds before the information is lost. it is the shortest -term memory and can be called as an element of memory. example: when we look at something and remember what it looks like, is just a second of observation. it degrades very quickly. it can also be considered as the process of perception rather than considering it as a memory.
