<h2>Movement of Continents</h2>

Explanation:

  • Alfred Wegener was a German astronomer who proposed the "continental drift" hypothesis in 1910.
  • Alfred Wegener was not able to explain the movements of the continent in how and in which way they are moved.
  • He failed in an attempt to explain with the use of tides made the theory undefinable fully.
  • Also, the major problem with Wegener's theory of Continental Drift was that there was no proper explanation of a mechanism.

A train 471 m long is moving on a straight track with a speed of 75.1 km/h. The engineer applies the brakes at a crossing, and l
hram777 [196]

Answer:

t = 37.6 s

Explanation:

As we know that train is initially moving with the speed

v_i = 75.1 km/h

now we know that

v_i = 20.86 m/s

now the final speed of the train when it crossed the crossing

v_f = 15 km/h

v_f = 4.17 m/s

now we can use kinematics here

v_f^2 - v_i^2 = 2 a d

4.17^2 - 20.86^2 = 2 a(471)

a = -0.44 m/s^2

Now the time to cross that junction is given as

v_f - v_i = at

4.17 - 20.86 = a(-0.44)

t = 37.6 s
