The difference in potential between these two points is 5 V.
Electric potential between the two points
The electric potential between two points is the work done in taking a unit postive charge from one point to another.
The difference in potential between these two points is calculated as follows;
W = qV
V = W/q
V = 10/2
V = 5 V
Thus, the difference in potential between these two points is 5 V.

If you are in a car that stops suddenly, what does your body continue to do?
Answer:
If the passengers were not wearing their seat belts:, then the passengers in motion would continue in motion. Assuming a negligible amount of friction between the passengers and the seats, the passengers would likely be propelled from the car and be hurled into the air. Once they leave the car, the passengers becomes projectiles and continue in projectile-like motion.
If they were: Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts. Being strapped tightly to the car, the passengers share the same state of motion as the car. As the car accelerates, the passengers accelerate with it; as the car decelerates, the passengers decelerate with it; and as the car maintains a constant speed, the passengers maintain a constant speed as well.

what is the most dense type of stars?
Answer:
A neutron star is the most intensely dense object in all the universe. Of course, the argument can be made that a black hole is the most dense, but considering that a black hole is technically beyond the event horizon, it is neutron stars that get the top spot for the being the ‘most dense’.

The number of waves produced by the musical instrument during the given time is 148 waves.
What is meant by frequency of a wave ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of the wave, f = 370 Hz
That means the wave completes 370 oscillations in 1 second. Or 370 waves are produced by the musical instrument in 1 second.
The time taken by the instrument to produce waves, t = 0.4 s
Therefore,
The number of waves produced by the musical instrument during this time is,
n = f x t
n = 370 x 0.4
n = 148
Hence,
The number of waves produced by the musical instrument during the given time is 148 waves.

An object travels a distance d with acceleration a over a period of time t according to the equation: d = at² After 2.3 seconds with an acceleration of 9.8 m/s2, how far does an object travel (rounding the answer to two significant figures)?
Answer:
A 26m
Explanation:
firstly the answer will not be part c as distance unit will be meters (m)
next, substitute the values of a and t as shown
[tex]\frac{1}{2} (9.8)(2.3)^2 = 25.921[/tex]
the answer rounded off to 2 significant figures will be hence 26m

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.
Pedro is planning to model how changes in weather affect evaporation from lakes. For his first experiment, he wants to test how humidity affects the evaporation rate. He places one beaker with 300 mL of water in a dry area, and he places another beaker with 300 mL of water near a humidifier. Which of the following variables does Pedro need to control during his experiment?
The aim of the experimental model is to test the effect of humidity (changes in weather) on evaporation (rates) from lakes
The control variables in an experiment are the variables that the experimenter intends to keep constant always so as to limit their effect on the measurements of the relationship between the dependent and the independent variable
Therefore in order to have a proper measurement of the effect of humidity on evaporation rate, other variables such as temperature, and the volume of the water in the experiment investigations which affect evaporation rate by the provision of heat, (temperature) and their heat capacity, (the volume and therefore, mass of water) should be controlled

magnets' persistent magnetic fields.Things that create their own persistent magnetic fields are known as permanent magnets.They have a north and a south pole and are built of magnetized ferromagnetic elements, such as iron and nickel.
More than one solution to the question "what causes a magnetic field?"
may be true.Charged particles that are in motion produce all magnetic fields.Due to the continually moving electrons inside, even the magnet on your refrigerator is magnetic. A magnetic field is produced along the axis of a wire loop by a current flowing through it.Curling the fingers of the right hand in the direction of the current through the loop and pointing the thumb in the direction of the magnetic field will reveal the direction of the field inside the loop. The magnetic field strength of an electromagnet or solenoid, depends on the number (N) of coil turns, the strength of current flowing through the coil in amperes, and its length L. This gives us: H = (NI)/L where NI represents the ampere-turns value.Items made of iron, cobalt, nickel, and steel are drawn to magnets.Paperclips are magnetic because they are often constructed of galvanized steel wire. Any of the following techniques can create a magnetic field:I Any type of magnet, including round, horseshoe, and bar magnets, may be employed.(ii) A current-carrying wire generates a field all around it.(iii) A current-carrying loop or solenoid Electric charges in motion are what generate magnetism.The smallest building blocks of matter are called atoms.There are electrons in every atom, which are charged particles.The electrons that make up an atom's nucleus, or core, spin like tops. Ampere noted that whenever an electrical charge is moving, a magnetic field is created.Similar to how an electrical current flowing through a wire creates a magnetic field, the spinning and circling of an atom's nucleus accomplishes the same.The magnetic field's orientation is determined by the spin and orbit directions. There are only two ways to create a powerful magnetic field.In the first, a solenoid is used, whereas in the second, a solenoid with an iron core is used. Magnetic materials found in nature are connected to magnetic fields.Instead of static charges, a magnetic field can be produced by moving charges.F = QVB, where Q is the charge and V is the charge's velocity perpendicular to the field B, describes the force acting on moving charges in a magnetic field.To learn more about magnetic field refer
