Answer:
- 2.7 x 10^-6 J
Explanation:
q1 = 1 nC at x = 0 cm
q2 = - 1 nC at x = 1 cm
q3 = 4 nC at x = 2 cm
The formula for the potential energy between the two charges is given by

where r be the distance between the two charges
By use of superposition principle, the total energy of the system is given by



U = - 2.7 x 10^-6 J
Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.
<h3>What is CT-Scane?</h3>
Computed tomography (CT) scan is a useful diagnostic tool for detecting diseases and injuries.
Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.
It uses a series of X-rays and a computer to produce a 3D image of soft tissues and bones.
CT is a painless, noninvasive way for your healthcare provider to diagnose conditions.
A CT scan lets your doctor see the size, shape, and position of structures that are deep inside your body, such as organs, tissues, or tumors.
Hence Computed tomography (CT) is an imaging tool that combines x-rays with computer technology to produce a more detailed, cross-sectional image of your body.

<u>Answer;</u>
<em>Spring constant </em>
<u>Explanation;</u>
The measure of a spring’s resistance to being compressed or stretched is the <u>spring constant</u>.
- The symbol of spring constant is K, since it is a constant. From the Hooke's law,for a helical spring or any elastic material, the extension force is directly proportional to the extension provided the elastic limit is not exceeded.
- Therefore; the spring constant = Force/extension. That is; K = F/e; where k is the spring constant, F is the extension force and e is the extension.
- Spring constant depicts the resistance of the spring to compressional and stretching forces.
Answer:
A leaf is falling from the tree.
Explanation:
If motion is in only one direction(x-direction) then it is know as one directional motion.
If motion is in only two direction (x and y directions) then it is know as two directional motion.
If motion is in only three direction (x , y and z directions) then it is know as three directional motion.
A bird is flying in the air -This is three directional motion.
A leaf is falling from the tree - This is two directional motion.
A train is running on track - This is one directional motion
A lady is crawling on the surface of the ball - This is three directional motion.
Therefore the answer is ---
A leaf is falling from the tree.
