<span>The reason why the shapes of the continents as of
today do not perfectly fi into to super continent because long time ago the
super continent was scattered into pieces. And as times go by, those smaller
parts of super continents undergo soil erosion caused by the water and other
way that causes their original shapes change.
Thus, if we are going to judge now if those smaller part of super continent,
they’re no longer gonna fit perfectly because through time their original form
changed</span>
Ivan Pavlov was the researcher that first realized that certain psychic secretions pointed to a simple but important form of learning.
The way he figured this out was when dogs paired certain things with food, and because of this, the dogs started salivating.
Answer:
the work done by the 30N force is 4156.92 J.
For this problem, they don´t ask you to determine the work of the total force applied in the block. They only want the work done for the force of 30N, with an angle of 30º respectively of the displacement and a traveled distance of 160m. So:
W=F·s·cos(α)=30N·160m·cos(30º)=4156.92J
Earth was the center of the universe
Answer:
(A) it's acceleration is negative but but it's velocity is positive
Explanation:
In the question it is given that begins to slow down so its speed is decreasing it is does not means that its speed is negative
For example let first the velocity of the car is 30 m/sec and when its velocity decreases it becomes 20 m/sec in 5 sec
So it is not negative at all
Now the acceleration is the rate of change of velocity
So acceleration is negative here
So option (a) will be the correct option
