Answers
Answer:
The distribution of charge is the result of electron movement. Since conductors allow for electrons to be transported from particle to particle, a charged object will always distribute its charge until the overall repulsive forces between excess electrons is minimized.

What does a higher value of k and a lower value of k tell about the strength of the spring? (Hint: In which case is it soft or stiff?)
Answers
Answer:
' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons

a muzzle velocity of 166 m/s.
Neglecting air resistance, what will be its
displacement after 8.6 s? The acceleration of
gravity is 9.8 m/s
Answer in units of m.
Answers
Explanation:
u=166m/s, v=0(at it's highest point final velocity is zero), a=9.8m/s², t=8.6s
by the formula, S=ut+½at².
S=[166×8.6+½.×9.8×(8.6)²]. ...by calculation
S = 1427.6+362.404
S=1790.004m

1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)

what supports a white dwarf against the crush of gravity?
Answers
Answer: In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.
Explanation:
Degeneracy pressure keeps a white dwarf from collapsing under its own gravity.
What is Degeneracy pressure?Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.
The maximum mass that a white dwarf can support against collapse is 1.4 solar masses due to the Chandrasekhar limit.

Habiba and selehadin have measured the voltage across a resistor to be 5.26V and the current flowing through in to be 0.41A they work out the resistance .
habiba says the resistance is 12.8 ohms .selehadin disagrees and says that is 13 ohm .
who is correct?.
Answers
Considering the definitipn of current, voltage, power, and Ohm's law,
CurrentThe flow of electricity through an object, such as a wire, is known as current (I). Its unit of measurement is amps (A). So current is a measure of the speed at which the load passes through a given reference point in a specified direction.
VoltageThe conductive force (electrical pressure) behind the flow of a current is known as voltage and is measured in volts (V) (voltage can also be referred to as the potential difference or electromotive force). That is, voltage is a measure of the work required to move a charge from one point to another.
Resistance
Resistance (R) refers to the resistance or opposition that an element has to the passage of electric current. It is represented by the symbol Ω and indicates the resistance that an element offers to the passage of electricity.
This means that the greater the resistance to the passage of current, the lower the intensity or amount of electricity that passes through this conductor.
The resistance that is measured in ohms.
Ohm's law
Ohm's law indicates that the current through a circuit is directly proportional to its voltage or voltage and inversely proportional to the resistance it presents.
Mathematically, Watt's law is expressed:
[tex]I=\frac{V}{R}[/tex]
So if you want to find resistance, the expression for its calculation is:
[tex]R=\frac{V}{I}[/tex]
This caseIn this case, you know:
V= 5.26 VI= 0.41 AReplacing:
[tex]R=\frac{5.26 V}{0.41 A}[/tex]
Solving:
R= 12.8 ohms
Habiba is right. The resistance is 12.8 ohms.
