Answer:
Along the Atlantic and Gulf Coasts of Florida, the land surface is also sinking. If the oceans and atmosphere continue to warm, sea level along the Florida coast is likely to rise one to four feet in the next century. Rising sea level submerges wetlands and dry land, erodes beaches, and exacerbates coastal flooding.

In an unusual move by the New York State Department of Transportation, all of the "speed limit" signs were replaced with "velocity limit" signs.Why are the devices in cars called speedometers and not velocitometers? a. What would such a sign look like? b. How could one travel faster than the old speed limit, without violating
Answer:
In an unusual move by the New York State Department of Transportation, all of the "speed limit" signs were replaced with "velocity limit" signs
The devices are called as 'Speedometer' and not 'Velocity meters' because speedometer only gives the magnitude of the speed but not direction while velocity is vector quantity which will show speed as well as direction of the vehicle. Such signs could possibly look like ' Maximum legally permissible strength of velocity for forward progress is 30'
Once can definitely travel faster using velocity meter than the old speed limit, it is because c=velocity includes displacement as it is vector. Hence it will allow the passengers to move in straight path without moving here and there on the road and it will help them reach their destination much faster than the old method without violating the rules.
A ball is thrown horizontally from the top of a building and strikes the sidewalk after 2.8 s. How tall is the building? Neglect air resistance.
Answer:
h = 38.41 m
Explanation:
Given that,
A ball is thrown horizontally from the top of a building and strikes the sidewalk after 2.8 s.
We need to find the height of the building. Let it is h.
Initial speed of the ball, u = 0
Using second equation of motion to find h as follows :
[tex]h=ut+\dfrac{1}{2}at^2\\\\\text{Put u = 0 and a = g}\\\\h=\dfrac{1}{2}gt^2\\\\=\dfrac{1}{2}\times 9.8\times 2.8^2\\\\=38.41\ m[/tex]
So, the building is 38.41 m tall.
A spy in a speed boat is being chased down a river by government officials in a faster craft. Just as officials boat pulls up next to the spy’s boat, both boats reach the edge of a 5.4 m waterfall. The spy’s speed is 14 m/s and the officials speed is 26 m/s.
How far apart will the two weeks vessels be when they land below the waterfall? The acceleration of gravity is 9.81 m/s^2. Answer in units if m.
Answer:
They are 7.4m apart.
Explanation:
I got the Feds 12.6 m ahead of the crooks when both boats hit the water under the falls.
If the same force is exerted on objects with different mass, then the object with less mass have a (smaller or bigger -pick one) change in velocity.
Please answer soon!!! is it smaller or bigger and if you can please explain as well !!!!
A block of cheese is sliding up an inclined surface that is not smooth.
What is the correct free body diagram for the block of cheese? (help!!!)
Answer:
Explanation:
KHAN ACADEMY
Free body diagram of a block of cheese is sliding up an inclined surface that is not smooth is shown in the diagram.
What is free body diagram?A graphic, dematerialized, symbolic representation of the body (a structure, element, or fragment of an element) in which all connecting "parts" have been eliminated is known as a free-body diagram.
Force acting on the block is F in upward direction and frictional force acting on the body in opposite to the motion is f. and weight of the body is mg. and normal reaction of the body is R = mgsinθ. where, θ is angle of inclination of the surface.
Then, free body diagram is according to the figure.
