Name 2 types of electric circuits based on their connection pattern
Answers
Answer:
When there are two or more electrical devices in a circuit with an energy source, there are a couple of basic ways by which we connect them. They can either be connected in series or parallel
[tex]\huge\bold\green{Answer:-}[/tex]
Series Circuit:-A series circuit has only one path for electricity to flow from one point to another. The amount of electricity in the circuit is consistent throughout any component in the circuit. When electricity flows through a series circuit, its rate of flow (speed) will never fluctuate. The total resistance of a series circuit equals the sum of individual resistances. The more resistors that a series circuit has, the more difficult it is for electrons to flow.
Parallel circuit:-A parallel circuit has multiple paths for electricity to flow from one point to another. According to website All About Circuits, “all components are connected between the same set of electrically common points.” Often, resistors and sources will be connected between two sets of electrically common points. In a parallel circuit, electricity can flow in multiple directions horizontally and vertically. The components of a parallel circuit will have the same voltage across their ends and will have identical polarities.

What is the current of a 24 ohm heating coil in a coffee maker plugged into a 120V outlet?
What voltage will produce 6 amps through a circuit that has 10 ohms of resistance?
Answers
Answer:
Current, I = 5A.
Voltage, V = 60V.
Explanation:
In part 1;
We were given the following data:
Resistance = 24 ohm
Voltage = 120V
To find the current,
According to ohm's law which states that, the current flowing through a conductor is directly proportional to the amount of potential voltage across its terminal and inversely proportional to the opposition to the flow of current (resistance) of the conductor.
Mathematically,
[tex] V = IR[/tex]
Where, V represents voltage measured in volts (v).
I represent current measured in amperes (A).
R represent resistance measured in ohms.
[tex]I = \frac{V}{R}[/tex]
Substituting into the equation, we have;
[tex]I = \frac{120}{24}[/tex]
I = 5amp
For part 2.
Given the following data
Current = 6
Resistance = 10ohms
Velocity =?
[tex] V = IR[/tex]
[tex] V = 6 * 10[/tex]
V = 60V
If a race car wants to change its velocity then a net force is
required to cause the necessary
Answers
Answer:acceleration
Explanation:
We define acceleration as the rate of change of velocity. So if a moving object wants to change its velocity, it needs to accelerate.
Thus the statement would be:
"If a race car wants to change its velocity then a net force is required to cause the necessary acceleration".
--------------------------------
Acceleration defines how the velocity changes, suppose that you are in one dimension and you move with positive velocity, if you have also positive acceleration your velocity will increase.
If you have negative acceleration your velocity will decrease.
But if we go to 2 dimensions we can see that acceleration is way more complex, because it is what allows the changes of direction of motion (by changing the direction of the velocity).
Now, acceleration comes from Newton's second law of motion:
F = m*a
Force equals mass times acceleration.
Then if we know that a car wants to change its velocity, it needs to apply a force such that it causes the necessary acceleration to change the velocity as wanted.
From this we can see that the complete statement would be:
"If a race car wants to change its velocity then a net force is required to cause the necessary acceleration"

Force make objects movable and to change their state. Various kinds of forces in nature balances altogether every processes in nature. The energy we gain or lost is due to some kind of force and resultant displacement.
What is force?Force is an external agent acting on an object to change its state of motion or to deform it. Force is a vector quantity and is characterized by its magnitude and direction. There are various kinds of forces such as gravitational force, magnetic fore, frictional forces, nuclear force etc.
Its due to gravitational force by earth that we are standing on the ground. We experience a weight due to this effect. Similarly the rotating current in the earth core generates the magnetic force of earth.
Every objects need a force to change its state or rest or motion. Similarly, the work done in any fields is the result of any force applied on the system.

weight of two people
Explanation:
Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
2nd Law: F=ma
a= change in velocity/time
a=F/m
say both objects must accelerate at a=2 m/s^2
object A is a wood plank, which is roughly 10 kg
object B is my metal ball, which has a mass of 100kg
now, solving for F applied to both objects
Fwood=(10kg)(2 m/s2)= 20 N
Fmetal=(100kg)(2 m/s2)= 200 N
the F needed to move the metal ball is 10 times greater than the F needed to move the wood plank. Hope this helped, I'm about to go fail my physics exam :)

Use the formula for momentum: Momentum = (mass) x (speed)
2.67 x 10⁴ kg-m/s = (mass) x (8.9 m/s)
Mass = (2.67 x 10⁴ kg-m/s) / (8.9 m/s)

1. A buoyant force of 790 N lifts a 214 kg sinking boat.What is the boat's
net acceleration?
Answers
Answer:
The net acceleration of the boat is approximately 6.12 m/s² downwards
Explanation:
The buoyant or lifting force applied to the boat = 790 N
The mass of the boat lifted by the buoyant force = 214 kg
The force applied to a body is defined as the product of the mass and the acceleration of the body. Therefore, the buoyant force, F, acting on the boat can be presented as follows;
Fₐ = F - W
The weight of the boat = 214 × 9.81 = 2099.34 N
Therefore;
Fₐ = 790 - 2099.34 = -1309.34 N
Fₐ = Mass of the boat × The acceleration of the boat
Given that the buoyant force, Fₐ, is the net force acting on the boat, we have;
F = Mass of the boat × The net acceleration of the boat
F = -1309.34 N = 214 kg × The net acceleration of the boat
∴ The net acceleration of the boat = -1309.34 N/(214 kg) ≈ -6.12 m/s²
The net acceleration of the boat ≈ 6.12 m/s² downwards
The boat's net acceleration is -6.12 m/s²
Given that:
Buoyant force = 790 N, mass (m) = 214 kg, acceleration due to gravity (g) = 9.81 m/s²
Net force = Buoyant force - mg = 790 - (214 * 9.81) = -1309.34 N
Net acceleration = Net force / mass
Net acceleration = -1309.34 N / 214 kg = -6.12 m/s²
The boat's net acceleration is -6.12 m/s²
