Are the number of wars in the world increasing or decreasing?
The number of interstate wars (wars betweens countries) has been decreasing over time. However, the number of intrastate wars (civil wars) have been increasing over time.
What is bernoulle's principle?
The Bernoulli principle states that the speed of a fluid increasing and its pressure decreasing happen at the same time. It's the physical property that planes depend on for flight, because the speed of the air beneath the wing is slower, and thus the pressure higher, pushing it up.
What does the slope of a speed vs time graph represent?
magnitude of acceleration at every point on the graph
If a body dropped from rest has a constant acceleration in free fall is the distance traveled by the body the same for each time interval?
No. Acceleration is the rate at which the speed is INCREASING. Since the speed is increasing,the distance traveled by the body in each time interval is also increasing.
What can acceleration be described as?
Acceleration can be described as the rate at which an object's velocity changes over time. It measures how quickly the object's speed or direction is changing. Therefore, it quantifies how much an object's motion is increasing or decreasing.
Is global wealth increasing or decreasing over time?
decreasing per capita
How do you convert displacement time graph into distance time graph?
Displacement is distance from starting point. If the object is always travelling in the same direction then they are the same. If the object turns round, the distance would still be increasing, however the displacement would be decreasing at the same rate.
How want to know that the gradient of a curve in displacement-time graph is increasing or decreasing?
If the gradient is a positive number the curve is increasing, and if the gradient is a negative number it is decreasing.
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
Are the number of wars in the world increasing or decreasing?
The number of interstate wars (wars betweens countries) has been decreasing over time. However, the number of intrastate wars (civil wars) have been increasing over time.
Does the rate of change have to be negative?
no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.
When the moon is growing larger?
It is called Waxing! _________________________ The Moon is always the same size. What we see increasing is the lighted part of the nearside of the Moon. When it is increasing, we call it "waxing"; when we see it decreasing, the word "waning" is used.
X3-3x plus 23 it is increasing function?
No. Although it is increasing most of the time, it is decreasing between x=-1 and x=1.
How do you interpret how an object is moving from a distance time graph?
If the distance is not changing, the object is not moving. If the distance is increasing or decreasing linearly then the object is moving at a constant velocity. If the distance is increasing or decreasing parabolically then the object is being accelerated or decellerated.
Why does the slope of a velocity time graph give you acceleration?
if there is a slope, the velocity is either increasing or decreasing. This is acceleration.
If the depth of the layer between 1000mb and 500mb is increasing with time if the surface temperature likely to be increasing or decreasing?
Assuming the depth of the layer is restricted to between 1000mb and 500mb, and increasing with time, it is almost certain that the surface temperature will remain constant, thus not increasing or descreasing.
What parameter indicates that the size of the human population is increasing?
The time needed to add 1 billion people is decreasing.
