The answer that best represents the energy particles of the interval
BC is number 3. The potential energy rises and average
kinetic energy will stay the same. This is best depicted by the diagram shown
above. As you can see, points B and C are the same.
•A wave produced by the acceleration of an electric charge and propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields
In other words : They are radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves
They are produced by the motion of electrically charged particles.
I hope this helped ! :)
Answer:
To determine whether a substance is an acid or a base, count the hydrogens on each substance before and after the reaction. If the number of hydrogens has decreased that substance is the acid (donates hydrogen ions). If the number of hydrogens has increased that substance is the base (accepts hydrogen ions
Answer:
Circular motion
Explanation:
Consider a car race, where you need to finish one lap in a circuit. Her the start line and the finish line are the same. So , where you start, is where you will be reaching after the race is done. So, the displacement here is <em>Zero</em> , since displacement is the distance from initial point to final point. But, as one can see, the distance travelled is not zero.
Say the race track is a circle of radius r meters. So the lap distance would be the circumference of the circle, which is 2πr m. So the distance travelled is 2πr m and the displacement is zero.
Hope this satisfies you :)
0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.
Explanation:
Data given:
moles of Cd
= 0.196 Moles
Molarity of the solution = 3.91 M
Volume in litres =?
molarity is calculated by the formula:
molarity = 
putting the values in the above formula and rearranging it for volume:
volume = 
volume = 
volume = 0.050 litres
0.050 litres of the water will be required to make a 3.91 M solution with 0.196 moles in it.
Molarity is the number of moles present in a given volume of solution which is given in litres. It is the measurement of the concentration of particular solute in a solution.
