Answer:
The two factors that affect the type of Shadows formed are stated below ::
- The distance between the source of land and the object.
- The angel where the ray of light falls on the object.
Answer: the iris is the function of a pupil
Explanation:
Answer:
It is not possible for the magnitude of displacement of an object to be greater than the distance that this object travelled.
Explanation:
The displacement of an object is difference between its final and initial position. On the other hand, the distance that an object travelled would be equal to the length of the path that this object takes when it moved from its initial position to the final position.
The distance an object travelled and the magnitude (length) of its displacement each represent the length of a path between the initial and final position:
- The distance travelled can represent the length of any path between these two points.
- On the other hand, the magnitude of displacement can only represent the length of the line segment that directly connects the two points.
On a flat surface, the shortest path between two points is always going to be a straight line segment connecting the two points. If these two points are the initial and final position of the object, the magnitude of displacement would simply represent the length of that straight line segment. It is not possible for the distance travelled to be any shorter than the shortest path between the two points. Therefore, the displacement of an object would always be less than or equal to the distance it travelled.
Complete question:
A force F is applied to the block as shown (check attached image). With an applied force of 1.5 N, the block moves with a constant velocity.
Approximately what applied force is needed to keep the box moving with a constant velocity that is twice as fast as before? Explain
Answer:
The applied force that is needed to keep the box moving with a constant velocity that is twice as fast as before, is 3 N
Force is directly proportional to velocity, to keep the box moving at the double of initial constant velocity, we must also double the value of the initially applied force.
Explanation:
Given;
magnitude of applied force, F = 1.5 N
Apply Newton's second law of motion;
F = ma
The applied force needed to keep the box moving with a constant velocity that is twice as fast as before;
Therefore, the applied force that is needed to keep the box moving with a constant velocity that is twice as fast as before, is 3 N
Force is directly proportional to velocity, to keep the box moving at the double of initial constant velocity, we must also double the value of the applied force.
Non renewable resources are resources that we can only use for so long until they’re gone and they can not be brought back. So like coal would be a non renewable resource. Renewable resources are resources that we can continue to use and we will always have them. An example of a renewable resource would be oxygen. We can breathe as much oxygen as we want but we will never run out of it.
