A straight horizontal line on a speed-time graph means the speedis constant. This means the speed is not changing over time.
How is this different from a distance-time graph?
Answers
Answer:
its devavtion is different from the distance changes process
Explanation:
Final answer:
A speed-time graph and a distance-time graph represent different aspects of motion. A horizontal line on the former indicates a constant speed (zero acceleration), while a straight, upward-diagonal line on the latter shows constant speed. A flat horizontal line on a distance-time graph shows no movement.
Explanation:
A speed-time graph and a distance-time graph each depict different aspects of motion. A horizontal line on a speed-time graph does indeed indicate constant speed or zero acceleration; the object is moving at a constant speed. However, a distance-time graph shows how the position of the object changes over time.
Let's take an example. If a car is traveling at a constant speed, on a speed-time graph, this would be represented by a horizontal line. The height of the line above the time axis represents the constant speed.
On a distance-time graph, a car moving at constant speed will be represented by a straight line with a positive slope. This is because the position of the car is continuously changing (it's covering distance), and at a constant rate. The slope of the distance-time graph gives us the speed of the car.
So, while a flat horizontal line in a speed-time graph indicates constant speed, a flat horizontal line in a distance-time graph would indicate no change in position, i.e., the object is not moving at all.

Medulla oblongata is lower part of brain.
Cerebrum and cerebellum are the upper hemispheres of the brain.
Explanation:
Cerebrum is the largest part of the brain and is composed of right and left hemispheres.
Cerebellum is the part of brain that lies inside the cerebellum.
Medulla Oblongata is lowest part of brain stem which is most vital part of the brain.
Thalamus is a small region of the brain located above the brain stem. Its main function is to transmit sensory signals to cerebral cortex.
Brain stem act as relay center connecting the cerebrum and cerebellum to the spinal chord.
Hypothalamus is the mid brain located near the pituitary glands. It is very small region of the brain but it plays an important role in maintaining the body temperature and releasing the hormones.

Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.

Explanation:
There are no options provided, however we can still answer the question.
In fact, the magnitude of the gravitational force between two objects is given by the equation:
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
We notice that:
- The gravitational force is proportional to the product between the masses
- The gravitational force is inversely proportional to the square of the distance between the masses
Therefore, in order to reduce the gravitational attraction by one half, we can do one of the following changes:
- Decreasing one of the masses to 1/2 of its original value: for example, if , the gravitational force becomes
- Increasing the distance by a factor of : in fact, if
, the gravitational force becomes
