Describe the motion shown in the lines
Bogdan [553]

Answer:

Solution

For figure (a)

During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.

During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.

During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.

For figure (b),

During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.

During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.

During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

Why is a key bed used?
Anna11 [10]
In geology, a key bed (syn marker bed) is a relatively thin layer of sedimentary rock that is readily recognized on the basis of either its distinct physical characteristics or fossil content and can be mapped over a very large geographic area.[1] As a result, a key bed is useful for correlating sequences of sedimentary rocks over a large area. Typically, key beds were created as the result of either instantaneous events or (geologically speaking) very short episodes of the widespread deposition of a specific types of sediment. As the result, key beds often can be used for both mapping and correlating sedimentary rocks and dating them. Volcanic ash beds ( and bentonite beds) and impact spherule beds, and specific megaturbidites are types of key beds created by instantaneous events. The widespread accumulation of distinctive sediments over a geologically short period of time have created key beds in the form of peat beds, coal beds, shell beds, marine bands, black  in cyclothems, and oil shales. A well-known example of a key bed is the global layer of iridium-rich impact ejecta that marks the Cretaceous–Paleogene boundary (K–T boundary). Please let me know if it works.
