The charge on the capacitor 2 (C₂) is 48μF.
Explanation of the circuit diagram
In the circuit diagram, C₁ and C₂ are in series connection, while C₃ is parallel to C₁ and C₂.
Same charge flows in a series arrangement (charge on C₁ = charge on C₂).Same voltage flows in a parallel arrangement (voltage on C₁, C₂ = voltage on C₃).Charge on capacitor C₁ and C₂[tex]Q_1 = Q_2 = Q\\\\V = \frac{Q}{C_1} + \frac{Q}{C_2} \\\\V = Q(\frac{1}{C_1} + \frac{1}{C_2} )\\\\Q = V (\frac{C_1C_2}{C_1 + C_2} )\\\\Q = 24 \times (\frac{6 \times 10^{-6} \times 3 \times 10^{-6}}{6\times 10^{-6} \ + \ 3 \times 10^{-6}} )\\\\Q = \frac{4.32 \times 10^{-10}}{9\times 10^{-6}} \\\\Q = 48 \ \mu C[/tex]
Thus, the charge on the capacitor 2 (C₂) is 48μF.

You are a passenger in a car, holding a cup of water in one hand. The driver is
forced to stop suddenly, causing the water in your cup to spill out in front of
you. The water likely spilled because:
A. every force is balanced by an opposing force.
B. an object in motion tends to stay in motion.
C. rapid changes in direction cause deceleration,
D. a force is exerted by a change in acceleration.
Answer:
the answer is b because an object in motion stays in motion
The water likely spilled because of inertia of motion such that an object in motion tends to stay in motion. So, option B is correct.
What is meant by inertia ?Inertia is defined as the property of matter by which it tends to continue its state of rest or uniform motion.
Here,
When you are travelling in a car, holding a cup of water in one hand and the driver of the car is forced to stop suddenly so that the water in the cup gets spilled out.
When the car was moving, the water in the cup was actually at the same speed relative to the car and cup. When the car is tend to stop suddenly, this causes a sudden change in acceleration of the car and thus the cup. As a result, the water in the cup spills out. This is due to the property of inertia that the water got spilled out.
According to the law of inertia, a body will preserve its state of rest or uniform motion unless an external force acts on it.
Here, the spilling out of water is the application of inertia of motion. That means the the water inside the cup which was moving forward and when the change in acceleration occurred, it got spilled in front of you thus tending to continue its state of motion.
Hence,
The water likely spilled because of inertia of motion such that an object in motion tends to stay in motion.

This is the correct answer
The magnitude of the electric field strength at that position is 2.6×10⁴ Newton/Coulomb.
What is electric field?An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity. It can also refer to a system of charged particles' physical field. Electric charges and time-varying electric currents are the building blocks of electric fields.
Given parameters:
Charge of the point charge: Q = 4.2 × 10⁻⁶ Coulomb.
Distance of the position from the position: r = 1.2 meter.
The magnitude of the electric field strength at that position = kQ/r²
= 9 × 10⁹ × 4.2×10⁻⁶/(1.2)² Newton/coulomb.
= 2.6×10⁴ Newton/Coulomb.

Out of all the largest x component is of Vector C of value 150i and Vector B will have highest y component of value 173j
What is vector ?Vectors are objects which have both, magnitude and direction. Magnitude defines the size of the vector. It is represented by a line with an arrow, where the length of the line is the magnitude of the vector and the arrow shows the direction.
Vector A = direction is in y direction = 100j
Since , this vector is only in y direction and have no component in x direction , so its x component will be = 0i
Vector B = direction is at angle of 60.0 degrees above the +x axis
Resolving into x and y components
x component = Vector B*cos(60) = Vector B * (1/2) = Vector B /2 = 200 /2
= 100i
y component = Vector B * sin(60) = Vector B * [tex]\sqrt{3}[/tex]/2 = 173j
Vector C = direction is along the +x axis

a rock with a mass of 10.0 kg is balanced on top of a large boulder. describe the forces acting on the rock, and use the concept of forces to explain why it stays on top the boulder.
Explanation:
The forces acting on the rock include Normal Force, Gravitational force & Friction force
It's possible for it to stay on the boulder because the normal force balances it's weight. also because static friction acts on the boulder up to it's limiting friction even if it were on an attempt to move as a result of air resistance. gravitational forces act upon it by mainly affecting it it's weight. as altitude increases, it's weight decreases since gravity varies from a height to another.

IntroductionHi ! Now, I will help to discuss about the gravitational force between two objects. The force of gravity is not affected by the radius of an object, but radius between two object. Moreover, if the object is a planet, the radius of the planet is only to calculate the "gravitational acceleration" on the planet itself,does not determine the gravitational force between the two planets. For the gravitational force between two objects, it can be calculated using the following formula :
[tex] \boxed{\sf{\bold{F = G \times \frac{m_1 \times m_2}{r^2}}}} [/tex]
With the following condition :
F = gravitational force (N)G = gravity constant ≈ [tex] \sf{6.67 \times 10^{-11}} [/tex] N.m²/kg²[tex] \sf{m_1} [/tex] = mass of the first object (kg)[tex] \sf{m_2} [/tex] = mass of the second object (kg)r = distance between two objects (m)Problem SolvingWe know that :

[tex] \sf{F = G \times \frac{m_X \times m_Y}{r^2}} [/tex]
