In Bolt’s fastest 100 meter, he accelerated from the starting block to a speed of 27.8 mi/hr in 9.58 s. What was his acceleratio

Gemiola [76]

Answer: 2.90mi/hr/s

Explanation:

Acceleration = Final Velocity - Initial over time

Acceleration = 27.8mi/hr over 9.58s.

Answer is 2.90mi/hr/s

What types of geologic structures would you expect to find in an area that had undergone compressional tectonic stress?

romanna [79]

Answer:

Folds.

Explanation:

A fold occurs when an originally flat or a plane surface of sedimentary rocks undergoes a bent or a curve and that may lead to permanent deformation.

And are formed due to the slumping of the sedimentary materials. They can form under the conditions of the compressional stress, hydrostatic pressure, and temperature gradient.

A set of folds is distributed at a region scale makes the fold belt and is commonly found in the orogenic zones or the mountain building areas. These folds are of various types as Anticlines, Synclines, and Antiforms.

A ball is thrown horizontally from the top of a building 100m high. The ball strikes the ground at a point 120 m horizontally aw

astraxan [27]

26.54 m/s is the magnitude of its velocity just before it strikes the ground

h=100m,v=20m/s,g=9.8m/s

time it takes to reach the ground,

$[t=\sqrt2h/g],[=\sqrt2*100/9.8=4.51s]$

x= 120m

t= 4.52

v= x/t

v= 120/4.52

v= 26.54 m/s

The "speed at which an object changes its location" can be expressed using a vector number called velocity. Consider a person who moves swiftly while taking two steps forward and two steps back while remaining in one location. Velocity is a vector quantity. Therefore, velocity is cognizant of direction. The direction must be taken into account when determining an object's velocity. A speed of 55 mph is not enough information. The direction must be used to appropriately depict the item's velocity. Simply said, the direction of the velocity vector indicates the direction of motion of an object.
