I believe that if you touch a metal sphere with a plastic straw, the straw would not have enough strength to push it. So in that case, the metal sphere will not move and will stay in one place.

Answer:
Oppressors have a repressive attitude toward others. They have a need for power and dominance.
Explanation:
Oppression is the painful experience of deliberate arbitrariness, violence and abuse of power inflicted on an individual, society or group of people. The term repression is often used synonymously for this.
Oppression arises from the general, also unconscious, assumption that a certain group of people is inferior or without rights. Oppression is seldom limited to governmental activities. Individuals can also be victims of oppression if they lack the solidarity of a social group.
Oppressive individuals, in turn, are those who exert repression on others. They are generally narcissistic and megalomaniacal people, who have a wrong self-perception of their virtues and negatively weigh the virtues of other people.
Answer:
D. the wind picking up dust and carrying it
Explanation:
Erosion is a process in which an agent transfer the top soil to another region, thereby exposing the lower soil. These agents have the ability to move the top layer of soil and deposit it at another place. The major agents in this case are; a running or flowing body of water and wind.
Therefore, the change to the Earth's surface that is an example of erosion is the wind picking up dust and carrying it. Thereby exposing the lower layers.

Answer:
I suppose that this is a problem of rotation with constant angular velocity.
This can be answered with arcs.
Suppose that we have a circle of radius R, and an angle A (A expressed in radians)
The length of that arc will be:
L = R*A
Now, a rotating object that rotates at a constant angular velocity, in a time t moves an angle A.
so if this object is moving in a circle of radius R, in the time t the distance traveled is the same that we found above.
L = R*A
Now, if the object moves away from the axis of rotation, we have that the radius of the circle R increases, then also does the value of L (the distance traveled in the time t)
Then, when the object moves away from the axis of rotation, in the same time t, the distance traveled will be higher, which means tath the tangential velocty increased (regardless the fact that the angular velocity is constant)
