What is the positive slop?
A positive slope goes upwards whereas a negative slope goes down wards
Do plants grow downwards?
No, plants do not always grow downward. Plant roots always grow downward due to positive gravitropism or positive geotropism. Plant shoots always grow upwards due to negative gravitropism or negative geotropism.
When the parabola concave downward and upward?
If the number in front of the x squared is negative, then the parabola will open upwards. The opposite occurs when the number is positive.
Why it is taken as negative when an object is thrown upwards against gravitation?
When we throw the object upwards we consider that upward direction as positive. Therefore, the velocity in that direction is positive but the acceleration due to gravity is in the opposite direction and so it is considered negative. But when the ball comes down again after reaching a certain height the velocity is in opposite direction to the earlier one and so the velocity now is negative as a result the acceleration is again negative.
What are some examples of negative geotropism?
A few examples of negative geotropism in plants include roots growing upwards in response to gravity (negative gravitropism), stems bending away from the ground to grow upwards (negative phototropism), and leaves folding upwards in response to touch or vibration (negative thigmotropism).
How can you tell if a porabola is opening up or down using ax2 plus bx plus c?
If a is positive, then the parabola opens upwards; if negative, then it opens downwards.
Why positive displacement are called positive?
Because it has been decided that the right and upwards directions in a plane are the positive directions and the left and downwards are negative. Originally, the decisions were arbitrary but conventionally agreed (in the same sort of way that North is usually shown at the top of a map). Any displacement in a positive direction is called a positive displacement.
Do bananas grow pointing up or down?
Yes, due to an effect called negative geotropism bananas grow upwards.
When can you used the positive acceleration due to gravity and negative acceleration due to gravity?
If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.
Why Ellingham diagram slopes upwards?
change in free energy is positive
If a is positive which way does the parabola open?
Upwards like a letter U
What is the difference between positive and negative gravitopism?
Positive gravitropism is the growth movement of a plant towards the gravity source, like roots growing downwards, while negative gravitropism is the growth movement away from the gravity source, like stems growing upwards. Both responses help plants optimize their growth in relation to gravity.
