Answer:
The strong attraction of each shared electron to both nuclei stabilizes the system, and the potential energy decreases as the bond distance decreases. If the atoms continue to approach each other, the positive charges in the two nuclei begin to repel each other, and the potential energy increases.
The interaction that lies between two atoms change should be considered as the stabilizes the system.
Reason for two atoms change:Since there is a strong attraction for every shared electron for both nuclei stabilizes the system and potential energy should be reduced due to this, the bond distance should be reduced.
In the case when the atom should continue to approach each other so here the positive charges in the two nuclei started to repel each other.

What is energy?
Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to ball in order to accelerate it. We must put in effort in order to apply a force. Following work, energy is transmitted to the item, which causes it to move at a new, constant speed. An ball will store energy as the result of its position is potential energy.

Olive and her friend Wellington are playing down by Captain Don's docks when they find an old chain. The old chain has only three links. By measuring with an old fish scale which is a permanent feature of the dock area, they determine that the total mass of the chain is 3.12 kg (the scale reads in newtons, but Olive knows how to calculate the mass of the chain from its weight). While playing with the scale and the chain (the chain is hanging vertically from the end of the scale, and Olive is holding on to the top of the scale with both hands, either moving the entire system upwards or downwards), Olive notices that if she is accelerating the chain either upwards or downwards, the scale no longer accurately reads the weight of the chain. When the Scale Reading is Larger than the Weight of the Chain At one point in their experiments with the chain and the scale, Wellington observes that the scale reads 47.00 N . Part A When the scale reads 47.00 N , what is the tension in the chain at the point where the lowest two links connect
Answer:
T₁ = 15.66 N
Explanation:
From the given information:
Using the free body system in the chain.
T - mg = ma
47 - 3.12 × 9.8 = 3.12a
47 - 30.576 = 3.12a
16.424 = 3.12a
a = 16.424/3.12
a = 5.26 m/s²
Now, by the free body diagram of the lowest link; the tension (T₁ ) in the chain is:
T₁ - (3.12/3) × 9.8 = (3.12/3) × 5.26
T₁ - 1.04 × 9.8 = 1.04 × 5.26
T₁ - 10.192 = 5.4704
T₁ = 5.4704 + 10.192
T₁ = 15.6624
T₁ = 15.66 N

A square metal plate of edge length 12 cm and negligible thickness has a total charge of 5.6 × 10-6 C. (a) Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.49 mm from the center) by assuming that the charge is spread uniformly over the two faces of the plate. (b) Estimate E at a distance of 29 m (large relative to the plate size) by assuming that the plate is a charged particle.
Answer:
a) 2.2*10^7 N/C
b) 60 N/C
Explanation:
To start with, we say that the
Area charge of the plate, σ = q/2A
σ = 5.6*10^-6 / 2(12*10^-2)²
σ = 5.6*10^-6 / 0.0288
σ = 1.944*10^-4 C²/m
Next, we find the electric field
Electric field, E = σ/Eo
Electric field, E = 1.944*10^-4 / 8.85*10^-12
Electric field, E = 2.2*10^7 N/C
b)
E = kq/r²
E = [8.99*10^9 * 5.6*10^-6] / 29²
E = 50344 / 841
E = 60 N/C
This means that the E at a distance of 29 m is 60 N/C

As the mass of object increased it is density increased
Answer:
True.
Explanation:
The density of an object is given by its mass divided by its volume. It can be given as follows :
[tex]d=\dfrac{m}{V}[/tex]
It can be seen that the density of an object is directly proportional to its mass. It means if the mass of an object increase, its density will also increase. Hence, the given statement is true.

Explanation:
The willingness to adequately consider the knowledge another speaker provides as well as show interest throughout the subject covered constitutes skills of effective listening. Truly wonderful hearing skills require an individual just to listen fully to the information such that a relevant reading of the information or a piece of evidence can be done.The starter motor of a car engine draws an electric current of 110 A from the battery. The copper wire to the motor is 4.20 mm in diameter and 1.73 m long. The starter motor runs for 0.95 s before the car engine starts up.
How much electric charge passes through the starter motor?
________
What is the current density in the wire?
_________
How far does an electron travel along the wire while the starter motor is on? (The density of conduction electrons in copper is n = 8.50×1028 1/m3.)
________
Answer:
a. 104.5 C b. 7.94 × 10⁶ A/m² c. 5.83 × 10⁻⁴ m/s
Explanation:
a. How much electric charge passes through the starter motor?
Using Q = It where Q = electric charge passing through the starter motor, I = current = 110 A and t = time = 0.95 s
So, Q = It = 110 A × 0.95 s = 104.5 C
b. What is the current density in the wire?
The current density, J = I/A where I = current = 110 A and A = cross-sectional area = πd²/4 where d = diameter of copper wire = 4.20 mm = 4.20 × 10⁻³ m
So, J = I/A
= I/πd²/4
= 4I/πd²
= 4 × 110 A/π(4.20 × 10⁻³ m)²
= 440 A/55.42 × 10⁻⁶ m²
= 7.94 × 10⁶ A/m²
c. How far does an electron travel along the wire while the starter motor is on? (The density of conduction electrons in copper is n = 8.50×1028 1/m3.)
To find how far the electron travels, we need to find the electron drift velocity from
J = nev where J = current density = 7.94 × 10⁶ A/m², n = electron density = 8.50 × 10²⁸ m⁻³, e = electron charge = 1.602 × 10⁻¹⁹ C, v = drift velocity of electrons and A = cross-sectional area of wire = πd²/4 where d = diameter of copper wire = 4.20 mm = 4.20 × 10⁻³ m
So, v = J/ne
Substituting the values of the variables into the equation, we have
v = 7.94 × 10⁶ A/m² ÷ (8.50 × 10²⁸ m⁻³ × 1.602 × 10⁻¹⁹ C)
v = 7.94 × 10⁶ A/m² ÷ (13.617 × 10⁹ Cm⁻³)
v = 0.583 × 10⁻³ m/s
v = 5.83 × 10⁻⁴ m/s

Answer:
Is fire matter? Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter.
URGENT HELP !! The coefficients of static and kinetic frictions for plastic on wood are 0.53 and 0.40, respectively. How much horizontal force would you need to apply to a 34.4 kg object to start it moving from rest?
Answer:
43.83 N
Explanation:
Given that,
The mass of an object, m = 34.4 kg
The coefficients of static and kinetic frictions for plastic on wood are 0.53 and 0.40, respectively.
The force of static friction,
[tex]F_s=\mu_smg\\\\F_s=0.53\times 34.4\times 9.8\\\\F_s=178.67\ N[/tex]
The force of kinetic friction,
[tex]F_k=\mu_kmg\\\\F_k=0.40\times 34.4\times 9.8\\\\F_k=134.84\ N[/tex]
Net force acting on the object is :
F = 178.67-134.84
= 43.83 N
Hence, this is the required solution.

g Consider a (12.5 A) cm long metal bar moving horizontally across a vertical magnetic field at a speed of (2.40 B) m/s. The magnetic field strength is 2.45 T. If the ends of the bar are connected to a (1.20 C) ohm resistor, find the power dissipated in the resistor while the bar is moving. Calculate the answer in watts (W) and rounded to three significant figures.
Answer:
Explanation:
emf due to movement of a rod of length L in a perpendicular to magnetic field B with velocity v is given as
emf = BLv
Putting in the given values ,
E = 2.45 x 12.5 x 10⁻² x 2.4
= .735 V
This emf produces current in resistance . Power consumed by resistance
V² / R where R is resistance , V is emf induced .
Power = .735² / 1.2
