Answer:
One should draw a diagram showing the placement of the charges.
When both charges of -Q are placed there will be no force in the vertical direction because of cancellation of forces.
A line from one corner of the square to the other makes an angle of 45 degrees,
2 cos 45 deg will be the force due to one charge.
2 * .707 = 1.41 N
So for both charges the force is (horizontal, vertical is zero)
2 * 1.41 = 2.82 N
b) is correct

The following statements are correct:
1. Graduated cylinder are used to measure volume.
2. Always read a graduated cylinder from the bottom of the meniscus.
Graduated cylinders are one of the instruments used to measure liquid substances in the laboratory. The most accurate way of reading measuring cylinder is to record the value at the bottom of the meniscus.
C, 5.3*10^3 kg m/s, is the correct answer to this question. Find the momentums of each object using p = mv, and then add the momentums together.
Hi!
Okay, so -
In the scientific method, we're going to complete the following steps...
<em>ask a question
</em><em>perform research to gather information on said question
</em><em>develop a hypothesis (what you think will happen)
</em><em>experiment to determine if your hypothesis is true or false
</em><em>evalute data
</em><em>draw a conclusion</em>
<em>report results
</em>
