The earth's tectonic plates are directly propelled by the convection in the __________.
1 answer:
The missing word here is <u>Asthenosphere.</u><u> </u>
The convection in the asthenosphere directly propels the tectonic plates of the earth.
Did you know that the asthenosphere is thought to remain malleable because of heat from deep within the Earth? It is thought to be lubricating the earth's tectonic plates' undersides and enabling movement.
The older, denser portions of the lithosphere that are dragged downward in subduction zones are stored in the asthenosphere, according to the theory of plate tectonics.
The lithosphere above is stressed by convection currents, and the cracking that frequently results manifests as earthquakes.
Magma is forced upward through volcanic vents and spreading centers by convection currents produced within the asthenosphere, which also results in the formation of new crust.

Answer:
1.4584 kg
Explanation:
Time period of a physical pendulum is given by
Here f=0.290 so
Mass =2.40 kg
d=0.300 m
g =9.8 m
So kg-
So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg-
The distance of the track is 600 m
Explanation:
The two cars move by uniformly accelerated motion, so we the distance they cover after a time t is described by the following suvat equation
where
u is the initial velocity
a is the acceleration
For car 1, we have
where
is the initial velocity of car 1
is the acceleration of car 1
So the equation can be rewritten as
For car 2, we have
where
is the initial velocity of car 2
is the acceleration of car 2
So the equation can be rewritten as
The two cars finish the race at the same time: this means that they cover the same distance in the same time t, so we can write
And solving for t, we find
Which gives two solutions:
t = 0 (initial instant)
t = 40 s
Therefore, the distance of the track is
