Answer:
B)velocity of object decreases
Explanation:
Consider the positive x axis as positive direction
Assume a body moving in negative x-axis direction
It's acceleration also alone negative x-axis direction
So according to our consideration
velocity and acceleration values are negative
That is both are towards negative x direction
But as both velocity and acceleration are in same direction, MAGNITUDE of velocity increases
But as magnitude increases in negative direction, velocity value decreases
But speed value increases(As speed is scalar and velocity is a vector)
The answer is X. I hope this helped
Answer:
where the y axis is
Explanation:
In more simple terms, a horizontal line on any chart is where the y-axis values are equal. If it has been drawn to show a series of highs in the data, a data point moving above the horizontal line would indicate a rise in the y-axis value over recent values in the data sample.
Answer: The option (C) is correct. The energy travels horizontally.
Explanation: When the pebble is thrown into a calm lake, there will be disturbance in the lake. The ripples are formed from the center and move outward because the energy is carried out from particle to particle.
The distribution of the energy among the particles starts from center and it will carry out outward. This disturbance will occur horizontally.
Therefore, the energy travels horizontally.
Answer: Dependent Variable
Explanation:
There are two types of variable in any kind of experiment:
Independent Variable which are mostly known as inputs
Dependent Variables which are mostly known as outputs
In any experiment, the researches focus on observing the output values (dependent variables) by intentionally changing the inputs (Independent variables).
e.g. If we are observing the strain on any object, we try to change the value of stress on that particular object.
Here strain is a dependent variable whereas stress is an independent variable because it doesn't depend on whatever the value of strain may be.
