Answer:
The final charge on each square plate is +10
Explanation:
The law of conservation of charge states that the charge in a system, isolated from the environment, can only be transferred to another system, as the charges can neither be destroyed nor created
Therefore, the sum of the charges in a system is always constant such that the net charge in the universe is constant
Therefore, given the amount of charges in the 1 cm side = -5
The amount of charge in the 2 cm side = +15
The net charge when they touch = The charge on the 1 cm + The charge on the 2 cm
The net charge when they touch = -5 + 15 = +10
The final charge on each square plate = +10.

A laboratory experiment requires 1300 milligrams of sugar. How many kilograms of sugar does the experiment require?
Answer:
The answer is 0.0013.
Explanation:
The answer is 0.0013 becuase the number is even and you have to divide it by ten if it is milligrams to kilograms so basically always divide by tens. Hope this is helpful <3
The experiment requires 0.0013 kg of sugar.
How conversion of milligram to kilogram is done?The milligram is the mass = 1/1,000 of gram (or) 0.0154 grains.
The milligram is an SI unit of weight where as kilogram is also a unit of weight in the metric system.In the metric system, " milli " is the prefix for 10⁻³ and " kilo " is the prefix of 10³.Abbreviation of mg - milligram, kg - kilogram.For example, 50 milligram is 50 mg and 50 kilogram is 50kg.kilograms = milligrams ÷ 1,000,000
The weight in kilograms is equal to the milligrams divided by 1,000,000.
Here,
1300 mg = ( 1300 ÷ 1,000,000) = 0.0013 kg
Hence, the answer is 0.0013 kg.

How many joules of potential energy does the pendulum have when it has 100 J of kinetic energy?
Answer: The maximum kinetic energy is 100 j.
Explanation: The kinetic energy = (potential energy) + (kinetic energy) and the potential energy of 0 J implying its kinetic energy is 100 J, which is its maximum.
If the maximum kinetic energy of the pendulum is 100 J, then the maximum potential energy of the pendulum will be 100 J as well.
The given parameters;
Kinetic energy of the pendulum = 100 JBased on the principles of conservation of mechanical energy, energy is always conserved.
If the maximum kinetic energy of the pendulum is 100 J, then its maximum potential energy will be 100 J as well.
M.A = K.E + P.E
where;
K.E is the kinetic energy P.E is the potential energyAt the lowest displacement of the pendulum;
M.A = K.E + 0
M.A = K.E = 100 J
At maximum displacement of the pendulum;
M.A = 0 + P.E
M.A = P.E = 100 J
Thus, if the maximum kinetic energy of the pendulum is 100 J, then the maximum potential energy of the pendulum will be 100 J as well.

What is happening to the heat in freezing?
Answer:
Heat is released.
Explanation:
Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled.

Answer:
90cm
Explanation:
2x5=10
10x9=90
Answer:
90 cm
Explanation:
To find volume, the formula is V=LWH
L is the length, W is the width and H is the height:
9 x 5 x 2 = 90
So V = 90 cm

What is the magnitude of the total displacement of the school bus from the start to the end of its trip?
Answer:
With the given information, we can assume that the start and the end of the trip are the same place. (Suppose, a tour where the bus starts at the school, then it goes to a given location, and then it returns to the school)
Now, the definition of displacement is:
The difference between the final position and the initial position.
But if the start and the end of the trip are the same place, then the initial and final position must be the same. Then the difference between the final position and the initial position is zero.
This means that the displacement of the school bus from the start to the end of its trip must be zero.

Use Hooke's Law and Newton's 2nd Law to derive a formula for the acceleration of an object of mass m on a frictionless surface which is attached to a spring with a constant k which is stretched a distance L. The acceleration should be in terms of m, k, and L.
Answer:
a = kL/m
Explanation:
Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:
F = kL
Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:
F = ma
Comparing both the forces, we get:
kL = ma
a = kL/m
which sentence describe newton's third law?
A. the acceleration of an object is equal to the net of force divided by the mass of an object
B. for an object to slow down or speed up the forces acting on it must be unbalanced
C. forces always comes in pairs that act in opposite directions

A wave traveling at 50.0 m/s has a wavelength of 10.0 m. What is the frequency of the wave? Show your work below?
Answer:
The frequency of the wave is 5 Hz
Explanation:
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).
Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).
The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.
In this case:
v= 50 [tex]\frac{m}{s}[/tex]f=?λ= 10 mReplacing:
50 [tex]\frac{m}{s}[/tex] = f* 10 m
Solving:
[tex]f=\frac{50 \frac{m}{s} }{10 m}[/tex]
f=5 Hz
The frequency of the wave is 5 Hz

What is inertia?Law of inertia:
Newton's First Law of Motion (Inertia) is an object at rest remains at rest, an object in motion remains in motion at constant speed through straight line unless acted by an unbalanced force.
Moment of inertia:
The sum of the product of mass of each particle with the square of its distance from the axis of the rotation is known as inertia or the moment of inertia.
Formula of Moment of Inertia I = Σ miri².
The three types of inertia are as follows:

Acceleration formula
a = (v₂ - v₁)/t
a = (26.8m/s - 24.8m/s)/4.3s
= (2m/s)/4.3s
≈ 0.47 m/s²
