The independent variable is changed by the experimentor, so it does not have to be changed.

Answer:

To match the cause to its effect

Explanation:

The experimenter alters the independent variable with the hopes of collecting data about how the dependent variable changes in response.Other variables have to be controlled so that any changes of the dependent variable are attributed to the known independent variable. If they are not controlled the experimenter has no way of knowing which variable caused the change. The scientific method would be crippled by that.

in general, what happens to the energy, order, and spacing of particles when a solid turns to a liquid?

vodka [1.7K]

For a solid to change its state of matter into liquid, energy is applied or heat is being used. With a solid, particles are very compacted and still, with a liquid they are not as compacted but can still take a defined shape.

Calculate the magnitude of the electric field at one corner of a square 2.42 m on a side if the other three corners are occupied

Karolina [17]

Ans:

12500 N/C

Explanation:

Side of square, a = 2.42 m

q = 4.25 x 10^-6 C

The formula for the electric field is given by

$E = \frac{Kq}{r^2}$
