Answer:
Continental Drift
Explanation:
Continental drift is the name of the theory that led to the development of theory of plate tectonics. Theory of plate tectonics is basically latest version of Continental drift, a theory which was initially put forward by scientist “Alfred Wegener” in year 1912. But he was unable to to explain the phenomenon of movement of continents around the planet.
Plate tectonics unified all the geologic descriptions & it proposed that one ought to explain all geologic explanations as though driven by the relative motion of these tectonic plates.
Answer:
Explanation:
This problem is based on conservation of angular momentum.
moment of inertia of larger disc I₁ = 1/2 m r² , m is mass and r is radius of disc . I
I₁ = .5 x 20 x 5²
= 250 kgm²
moment of inertia of smaller disc I₂ = 1/2 m r² , m is mass and r is radius of disc . I
I₂ = .5 x 10 x 2.5²
= 31.25 kgm²
3500 rmp = 3500 / 60 rps
n = 58.33 rps
angular velocity of smaller disc ω₂ = 2πn
= 2π x 58.33
= 366.3124 rad /s
applying conservation of angular momentum
I₂ω₂ = ( I₁ +I₂) ω , ω is the common angular velocity
31.25 x 366.3124 = ( 250 +31.25) ω
ω = 40.7 rad / s .
Answer:
29.4 m.s
Explanation:
Vf = vo + at v o = original velocity = 0 in this case
Vf = at
= 9.81 m/s^2 * 3 = 29.4 m/s
Answer:
Newton's F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a)
