An equal amount of charge flows out of the opposite plate for every charge that enters and builds up on the first plate. The capacitor appears to be conducting current as a result.
In most metals, current is made up of moving electrons, therefore conventional current traveling downhill indicates true upward electron movement.
How do capacitors work?A capacitor is a device that can store electrical energy. It is made by taking two electrical conductors (items that allow electricity to flow through them) and separating them with an insulator (a substance that doesn't let electricity flow very well). The terms charging and discharging refer to the addition of electrical energy to and removal of energy from capacitors, respectively.
How does capacitance work?The capacitance of a capacitor determines how much electrical energy it can store. A capacitor's capacitance can be compared to a bucket's volume: a larger bucket can hold more water, while a larger capacitance allows a capacitor to store more electricity. There are three methods for increasing a capacitor's capacitance. The first is to make the plates larger. The plates could also be brought closer to one another. Making the dielectric as effective an insulator as you can is the third method. Diverse materials are used as dielectrics in capacitors. In transistor radios, a sizable variable capacitor with nothing but air in between its plates performs the tuning function.

84 g of a metal at an initial temperature of 72°c releases 553 j of heat. Calculate the final temperature of the metal if its specific heat capacity is 0. 13 j/g⋅k.
The final temperature of a 84.0g metal with an initial temperature of 72°C releases 553J of heat is 395.6K.
How to calculate final temperature?The temperature of a substance can be calculated by using the following formula:
Q = mc∆T
Where;
Q = quantity of heat absorbed or releasedm = massc = specific heat capacity∆T = change in temperatureInitial temperature in Kelvins = 72°C + 273 = 345K
The final temperature is calculated as follows;
553 = 84 × 0.13 × (T - 345)
553 = 10.92T - 3767.4

The sum of the forces exerted on an object must be zero since, in accordance with Newton's first law of motion, an object moving at a constant speed experiences no net external force. F net = 0 F net = 0 or F = 0 are two ways to express mathematically that an object is not being affected by any net external forces.
What is the first law of motion, according to Newton?First Law of Newton: Inertia
According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. Inertia is the propensity to resist changes in a condition of motion.
He second equation swaps out p for mv since p=mv. V stands for the object's speed, t stands for time, and F stands for force.
Newton's second law of motion uses the inertia formula "Force = Mass * Acceleration" to describe this phenomena and property. According to the formula, heavier objects need greater force to modify their acceleration.

what do we mean by the ptolemaic model? how did this model account for the apparent retrograde motion of planets in our sky?
The planets traveled on circles that orbited Earth in bigger orbits. The apparent retrograde motion of the planets was explained by this motion of "circle upon circle."
Ptolemy used eccentricity with an epicyclic model to account for the motion of the planets. Each planet in the Ptolemaic system circulates uniformly along a circular path known as an epicycle, with Earth at its center and around a larger circular path (deferent). The Ptolemaic System's central tenet was that the Sun and all other planets revolved or circled around the Earth, which served as the universe's center of gravity. Geocentric theories are those of the cosmos that place the earth at its center, like Ptolemy's. According to the Ptolemaic model, the moon, sun, stars, and other planets revolved or rotated around the earth, which was thought to be at the center of the universe. In this model, the globe was thought to revolve around itself.So, the planets traveled on elliptical orbits that encircled Earth in bigger radii.

What is the time of flight?
Every projectile remains in the air for a certain period of time the amount of time the projectile space in the air is known as time of flight for the same velocity with different angles the time of flight can vary.
given:
height of the table = 1.20 meters
range of the projectile = 0.55 meters
first, we need to determine the time of flight of the projectile using the height of the table.
the time of flight for both the motion i.e., in x axis and y axis will be same.
using newtons second law of motion we get,
s = u × t + 0.5 × a × t²
where,
s is displacement in y axis
u is the initial velocity of the basketball
t is the time of flight
a is the acceleration due to gravity
substituting value in newtons second law of motion we get,
1.20 = 0 + 0.5 × 10 × t²
t² = 0.24
t = 0.49 seconds
now we will use this to find the velocity of the basketball using time distance relationship,
distance = speed × time
0.55 = velocity of the basketball × 0.49
velocity of the basketball = 1.22 m/s
therefore, the velocity of the basketball rolling off a 1.20 m high desk and strikes the floor 0.55 m away from the base of the desk is 1.22 m/s.

The total force will be 100 N .
This is a use of Newton's Third Law, which states that "there is an equal and opposite reaction to every action." Only if the other end of the string applies a force of 100 N in the opposite direction can someone at one end of the string apply a force of 100 N to the other end.Imagine that If suspend a 1 kilogram load from a spring scale. This has a pulling force of about 100 N. Next, take the weight off the spring scale and fasten it to a wall. Pull the scale until 1 kilogram is displayed. The weight and gravity's downward force of 100 N was the same when it was dangling. Consider what would happen if the end of the thread was linked to one spring scale and a second spring scale was attached to the wall.

The neutron is indeed a subatomic particle with the symbol n or n0 that is slightly heavier than a proton and has a neutral charge (one that is neither positive nor negative). Atomic nuclei consist of protons and neutrons. Protons and neutrons are both referred to as "nucleons" because of how similarly they behave inside the nucleus and because they both have masses that are roughly equal to one atomic mass unit. Nuclear physics explains their interactions and characteristics. Each proton and neutron is made up of three quarks, so they are not fundamental particles. The arrangement of electrons around an atom's heavy nucleus largely determines its chemical properties. The number of protons, or atomic number, determines the charge of a nucleus, which determines the electron configuration.

The drag force is inversely proportional to velocity squared. Consequently, we may express the force ratio as,
F1 / F2 = V²1 / V²2
We can write values in place of them.
2.3 / F2 = 20² / 35.6²
F2 = 7.29 N
As a result, at 35.6 m/s, our drag will be 7.29 N.
The drag force is the force a solid body experiences while it is moving in relation to a fluid. Drag, for instance, on a moving ship or a flying jet. Thus, a drag force is the resistance a body traveling through a fluid, such as air or water, produces.
One example of the drag force, which is the force that objects experience when moving through a fluid, is air resistance (liquid or gas).
