Answer:
v = u + a t
80 = 50 + a * 30
80 - 50 /30 = a
a = 30/30 = 1 m /s 2
s = u t + 1/2 at ^2
s = 50 * 30 + 1/2 * 1 * 30^2
s = 1500 + 1/2 * 900
s = 1500 + 450
s = 1950 m
Answer:
The likely function of the behavior are explained in the explanation column below.
Explanation:
Crayfish are invertebrates typically considered omnivores and scavengers and are found in water bodies like, lakes and ponds, streams and rivers, though they are not capable of swimming they can only propel backwards in water to evade predators.
Crayfish gill which is at the base of each leg are covered by the carapace, which enables the crayfish provides a water channel. Crayfish uses its swimmerets to create water current.
The carapace is in the exoskeleton of the crayfish. The exoskeleton has hair that enable the crayfish to sense movements in water. When legs are moved in a rhythmic back-and-forth motion, it aids the crayfish to circulate water to the gills which is a chain of activity that was first commenced as the crayfish first exposes the gills to water by lying on one side.
<span>In some states, like New York, driving permits are valid for up to 5 years, while in other states they may expire after as little as 1 year. You will usually have to hold your permit for 6 months or longer before you're eligible to receive a driver's license.</span>
I think we have to experiment so we can learn different things
