What happens when you touch thermometer Mercury?
It doesn't sound like a good idea to experiment with this - mercury is quite toxic.
What happens when a magnet touches water?
nothing happens. Add. But the idea of an interaction is intriguing, and 'hydrodynamic propulsion' is a standard stuff of science fiction. Used in some Clive Cussler books as well.
Explain why the unit for velocity is ms but unit for acceleration is ms2?
That is because, basically, velocity and acceleration are not the same thing. Understanding the units for velocity should be quite clear. 5 m/s, for example, means that an object changes its position 5 meters, every second. Acceleration is a little more confusing. After all, "second squared" by itself doesn't have any physical meaning! The idea, however, is quite clear once you understand the following. Acceleration is a change in velocity, per time unit. Let's say an object changes from 5 to 8 m/sec in 1 second. Then, its speed changes 3 m/sec in one second. That is an acceleration of (3 m/sec) / 1 sec = 3 m/sec/sec. This is often abbreviated to 3 m/sec2. Similarly, to understand the base units that make up other derived units, you must follow the reasoning, how the units are defined.
What does it mean to have second squared in the denominator of the unit for acceleration due to gravity?
Intriguing, right? - The basic idea is that acceleration is a change in velocity over time; and velocity is expressed in meters per second. So if, for example, an object changes its velocity from zero to 5 m/s, within one second, you will have an acceleration of (5 m/s) per second, or 5 m/s/s, or simply. 5 m/s2. The "second squared" by itself has no physical significance, only as part of larger units, such as acceleration, force (equals mass x acceleration), work (equals force times distance), etc.
What is the acceleration of a 4000 kg airplane that has a force on it of 24000 N?
The idea is to divide the force by the mass (according to Newton's Second Law). The answer will be in meters/second2.
Why is it important to have only one manipulated variable in an controlled experiment?
So you can know which changes are contributed to which factor. Otherwise, you don't get a clear idea.
What is a correlation variable?
Any variable can be a correlation variable. In some cases there may be no apparent correlation but that, in itself, that means nothing. For example, the x and y coordinates in the equation of a circle (or any symmetric shape) are not correlated. On the other hand, there is a pretty good correlation between my age and the number of cars in the world.A correlation variable is simply a variable that you study to see if changes in the variable that you are interested in is, in any way, related to changes in the correlation variable, and to get some idea of the degree to which they move in line.
What is the number that replaces a variable?
The whole idea of a variable is that any number can replace it.
Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
What is the idea that geologic change happens suddenly?
catastrophism is the idea that geologic change happens soddenly
How do you find x and y in system of equations?
The basic idea here is to look at both equations and solve for either x or y in one of the equations. Then plug the known value into the second equation and solve for the other variable.
A widely accepted scientific idea which cannot be proven nor disproven?
Dependent variable
The musical form that takes one idea and then changes it in some way is?
The musical form that takes one idea and then changes it in some way is theme and variations.
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
Assigning a value to a variable from a mathematical operation is considered a?
good idea. Example: a= b+c;
How do i know how much to water my lawn, is there a guage?
You can get gagues, and is a good idea if you're in a variable climate.

i have no idea lol
