What causes Seafloor spreading

Physics
2 answers:
Rasek [7]3 years ago
5 0
Sea floor spreading is caused by the continual injection of magma from the sea bed in between ridges found in mid-ocean. Injection of magma causes formation of new sea floor. Forces cause the sea floor on each side of the mid-ocean ridge to move in opposite directions, each side belonging to a different lithospheric plate. This process is continuous and results in an ever widening (spreading) sea floor at the expense of area lost elsewhere on the planet. Seafloor spreading ends when mid ocean ridges are subducted.

a dragster gets to a peed of 112m/s over a distance of 300m from rest. Determine the acceleration of the dragster.
madreJ [45]

A dragster gets to a speed of 112 m/s over a distance of 300 m from the rest, then the acceleration will be 20.9 m/s².

<h3>What is Acceleration?</h3>

The rate of change in an object's velocity with respect to time is known as acceleration in mechanics. The vector quantity of accelerations. The direction of the net force that is acting on an object determines its acceleration.

Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well. The definition of acceleration is the change in velocity vector over a time interval divided by the time interval.

According to the question, the given values are :

Final velocity, v = 112 m/s.

Initial velocity, u = 0 m/s

Distance, s = 300 m.

Use the equation of motion,

v² - u² = 2as

112 ² - 0 = 2 (a)(300)

a = 12544/600

a = 20.9 m/s².

Hence, the acceleration of the dragster will be 20.9 m/s².

What is your hypothesis (or hypotheses) for this experiment?
Ad libitum [116K]

Answer: In that case, Put something like "My hypothesis is that the car will take (x) seconds to get to checkpoint 1, (x) seconds to get to checkpoint 2, (x) seconds to get to checkpoint 3, and (x) seconds to get to checkpoint 4" Replacing x with random numbers, or number close to the actual found numbers, but honestly as long as the guesses arent outrageous you should get the question right
