Answer:
sulcus
Explanation:
A sulcus is an indentation or depression in the brain that causes it to look like it ridges or folds
Cerebral sulci and fissures are grooves between the adjacent gyri on the surface of the cerebral hemispheres.
Sulci can be basically can be divided into three basic function
limiting sulcus: This happens to develop between areas differing in structure and function, for example central sulcus
axial sulcus: This develops along the axis of a rapidly growing/developing area (e.g. calcarine sulcus)
operculated sulcus: a sulcus may be between two structurally-different areas and a third sulcus may lie in its wall and does not appear on the surface (e.g. lunate sulcus)
Answer:
d. Two soccer balls that are touching each other
Explanation:
Let 
be the mass of a tennis ball, 
is the mass of a soccer ball.
As the mass of a soccer ball is more than the mass of a tennis ball, so
Let 
be the distance between the centers of both the balls near each other and 
be the distance between the centers of both the balls touching each other.
So, 
The gravitational force, F, between the two objects having masses M and m and separated by distance d is
Where G is the universal gravitational constant.
As, the gravitational force is directly proportional to the product of both the masses and inversely proportional to the square of the distance between them, so selecting the larger mass (, soccer ball) separated by a lesser distance (, touching) to get more gravitational force.
Therefore, there will be a larger gravitational force between them when two soccer balls touching each other.
Hence, option (d) is correct.
The spring exerts on each block an outward force of magnitude
<h3>What is kinetic energy?</h3>
The kinetic energy is the energy that it possesses due to its motion.
To accelerate an object, we need to apply force. To apply force, we have to be compelled to do work. When work is done on an object, energy is exchanged, and the object moves with a unused steady speed. We call the energy that's exchanged kinetic energy, and it depends on the mass and speed accomplished.
Kinetic energy is a scalar quantity, it is entirely described by magnitude

The first box is Acceleration
the second box is Speed
the third box is Speed
the fourth box is velocity
the fifth box is Speed.
The reason the first box is acceleration is because let's say you are about to go up a hill you need to add acceleration to make it up the hill, I was going to say speed but it wouldn't said what mph was.
The reason the second, third,and fifth box is speed is because it is telling up that an object is going _mph (the blank is where you put your estimate of speed of an object).
The reason the fourth box is velocity is because velocity is both magnitude and direction so in the fourth box it says that the race car made a slight left turn which is a direction that the car is going in.
Hope this helped :)
Have a great day
