Answer:

a. Load.

b. Fuse.

c. Source.

d. Wire.

e. Switch.

Explanation:

An electric circuit can be defined as an interconnection of electrical components which creates a path for the flow of electric charge (electrons) due to a driving voltage.

Generally, an electric circuit consists of electrical components such as resistors, capacitors, battery, transistors, switches, inductors, fuse, etc.

Matching the given circuit parts to their appropriate functions, we have;

a. Load: an appliance or device that uses electricity source like bulbs, computers, television, radio, etc.

b. Fuse: it is a safety device made from materials that easily melt even before the wires carry too much current.

c. Source: it is where electricity came from like batteries and generators.

d. Wire: it is the pathway of electricity from the resources (source) to the load.

e. Switch: it controls the flow of electricity from the source. It is typically used to turn ON or turn OFF a load.

Answer:

The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second.

Answer: hello your question is poorly written attached below is the well written question

answer: 4.9 * 10^-5 T

Explanation:

Current ( i ) = 39.30 A

Determine the magnitude of the B-field at Point P

Mag of B-field at Point P = μo*I / 2π*r --- ( 1 )

where : I = 39.30 , μo = 4π * 10^-7 , r = 8*10^(-2)

Input values into equation 1

( 10^-7 * 39.30 ) / ( 8*10^-2 )

∴ Mag of B-field = 4.9 * 10^-5 T

Answer:

4E

Explanation:

From the question given above, the following data were obtained:

Initial elongation (e₁) = 4 cm = 4/100 = 0.04 m

Initial energy (E₁) = E

Final elongation (e₂) = 0.04 + 0.04 = 0.08 m

Final energy (E₂) =?

The energy stored in a s spring is given by:

E = ½Ke²

Where

E => is the energy

K => is the spring constant

e => is the elongation

From:

E = ½Ke²

Energy is directly proportional to the elongation. Thus,

E₁/e₁² = E₂/e₂²

With the above formula, we can obtain the final energy as follow:

Initial elongation (e₁) = 0.04 m

Initial energy (E₁) = E

Final elongation (e₂) = 0.08 m

Final energy (E₂) =?

E₁/e₁² = E₂/e₂²

E / 0.04² = E₂ / 0.08²

E / 0.0016 = E₂ / 0.0064

Cross multiply

0.0016 × E₂ = 0.0064E

Divide both side by 0.0016

E₂ = 0.0064E / 0.0016

E₂ = 4E

Therefore, the final energy is 4 times the initial energy i.e 4E

Explanation:

Cho các dữ liệu sau đây;

Khối lượng = 25 kg

Nhiệt độ ban đầu = 25°C

Nhiệt độ cuối cùng = 100°C

Nhiệt dung riêng = 4,18 * 10³ = 4180 J/kg.K

Để tìm nhiệt lượng cần thiết;

Về mặt toán học, nhiệt dung được cho bởi công thức;

[tex] Q = mcdt[/tex]

Ở đâu;

Chuyển đổi:

Nhiệt độ ban đầu = 25°C đến Kelvin = 273 + 25 = 298 K

Nhiệt độ cuối cùng = 100°C đến Kelvin = 273 + 100 = 373 K

dt = T2 - T1

dt = 373 - 298

Answer:

False

Explanation:

Electromagnetic strength is inversely proportional to separation distance

answer:projectile motion

Explanation:

Since gravity acts vertically, there is no acceleration in the horizontal (x) direction. This special type of two-dimensional motion is called projectile motion.

Answer:

.......................

The magnitude of your displacement can be equal to the distance you covered, or it can be less than the distance you covered.  But it can never be greater than the distance you covered.

This is because displacement is a straight line, whereas distance can be a straight line, a squiggly line, a zig-zag line, a line with loops in it, a line with a bunch of back-and-forths in it, or any other kind of line.

The straight line is always the shortest path between two points.

Answer:

Explanation:

E: True. The last one is the true statement.

D: False: If home lights were connected in series, when you turned one of them off, they all would go off.

C: The opposite is true. Electrons flow towards the positive pole of a battery. Just as with people, opposites attract.

B: False. What is being described is a parallel circuit. In a series circuit. the positive pole of one battery is connected to the negative pole of the next battery. The other end of each battery is connected to the load.

A: False. There is a voltage drop on each load in series. These drops add together to equal the source voltage.

Explanation:

newtons 3rd law says that all forces have equal and opposite reactions so it would be equal to for the first one. but the acceleration depends on the mass of the object and because the truck is more massive, the acceleration would be slower, or less than.

Answer:

5

Explanation:

The light intensity may be defined as the strength of the light or the magnitude of its brightness that a source of light can produce.

The light threshold is the minimum intensity of the light that our eye can detect and the ability to adapt to darkness.

In the context, Daniel wishes to find if can notice the difference in the intensity of the light when he add 5 candles to the set of 50 candles.

He noticed that when he added 5 candles, he could notice the difference in the intensity and when he added less than 5 candles to the set of 50 candles he could not detect.

Thus, the difference threshold for Daniel to detect the change in the intensity of the light is 5 candles.

Answer:

The face of the cube towards A. is bright and shiny and the face towards B is dull black. State with reason the adjustments that should be made on the distances X1 and X2 so that the rate of change of temperature in both balloons is the same.

Explanation:

Convection is the mechanism by which heat is transferred from the cube to the balloon. Convection is the movement of currents inside a liquid or gas that transfers heat energy.

Convection is a method of heat transfer in which a fluid or gas, such as air or water, is moved. A hotter liquid or gas loses density and rises, while a colder, denser liquid or gas replaces it by sinking. Convection is the term used to describe the movement of gases or liquids due to temperature differences.

When the cube is heated, the air around it becomes less dense and rises; On the contrary, the cold air from all around fills the space. As a result, heat energy is transferred from the cube to the balloons via convection currents.

Therefore, Convection is the mechanism by which heat is transferred from the cube to the balloon. Convection is the movement of currents inside a liquid or gas that transfers heat energy.

Answer:

The apple

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

[tex] P.E = mgh[/tex]

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Basically, the potential energy of any physical object is directly proportional to the mass and height of the object. Thus, an increase in either the mass or height of an object would cause an increase in the potential energy possessed by the object.

Hence, an apple weighing 4 ounces would have more potential energy than a cherry that weighs 1 ounce.

Explanation:

The change in entropy is a measure of temperature. When the temperature of a compound or a system increases, there will be more randomness in the system.

The boiling point is directly related to the number of carbon atoms but is indirectly proportional to the branching in a hydrocarbon.

Butane and methyl propane, both have 4 carbon atoms.

But, butane has 4 carbon atoms in a straight chain while methyl propane has 3 carbon atoms in a straight chain and 1 methyl substituent which makes it a branched hydrocarbon.

Thus, the boiling point of methyl propane will be less than the butane. Likewise, the pattern in entropies will be seen.

The magnitude of the point charge is 3.496 x 10⁻⁶ C

Explanation:

Given;

radius of the surface, r = 14.3 m

magnitude of the potential, V = 2.2 kV = 2,200 V

The magnitude of the point charge is calculated as follows;

[tex]V = (\frac{1}{4\pi \epsilon _0} )(\frac{Q}{r} )\\\\V = \frac{KQ}{r} \\\\Q = \frac{Vr}{K} \\\\Q = \frac{2,200 \times 14.3}{9\times 10^9} \\\\Q = 3.496 \times 10^{-6} \ C\\\\Q = 3.496 \ \mu C[/tex]

Therefore, the magnitude of the point charge is 3.496 μC
