Calculate the resistance of a circuit with 1.5 A and 120 V. Use the appropriate formula from the list of formulas on the
whiteboard
A 60 watts
60 ohms
C 80 ohms
Answer:
Option C (80 ohms) is the right answer.
Explanation:
The given values are:
Current,
I = 1.5 A
Voltage,
V = I20 V
As we know,
⇒ \(V=IR\)
or,
The resistance will be:
⇒ \(R=\frac{V}{I}\)

QUESTION 1: Different Line Types Look at the drawing of a different bicycle pump below. This drawing is accurate, so we call it a scale draw It is four times smaller than a real pump. We say it is drawn to a scale of 1:4. That means that if you meas the length of the outer tube of this drawing, it will be four times smaller than the outer tube of the real pu F + 320 Figure 9: Bicycle pump. Scale 1:4 Why is the outer tube of this pump drawn with solid lines?
Answer:
The outer tube of the pump is drawn with solid lines because it represents the visible edges of the object, which are the most important and prominent features of the drawing. Solid lines are used to indicate visible edges, while other types of lines such as dashed or dotted lines are used for hidden or construction lines that are not meant to be seen in the final drawing.
Explanation:
When drawing an object, it's important to distinguish between the visible edges and the hidden or construction lines. The visible edges are the lines that represent the outer contour or silhouette of the object, which define its shape and form. In the case of the bicycle pump, the outer tube is the most prominent and recognizable feature of the pump, so it's drawn with solid lines to emphasize its importance and to make it stand out from the other parts of the pump.
On the other hand, the hidden or construction lines are used to guide the drawing process, to show the internal structure or components of the object, or to indicate the position of other features that are not visible from the current viewpoint. These lines are usually drawn with dashed or dotted lines to distinguish them from the visible edges and to avoid confusion.
By using different types of lines, the artist can create a clear and accurate representation of the object, with all the relevant information conveyed in a concise and understandable way. This is especially important in technical or scientific drawings, where precision and clarity are essential for conveying complex ideas or designs.

Perchuty (P. z fan ce the Treffe resistivalyThe law of resistivity.
We can see here that the law of resistivity, also known as Ohm's law, states that the electrical resistance of a conductor is directly proportional to its resistivity and length, and inversely proportional to its cross-sectional area.
How is law of resistivity represented?The Law of resistivity can be mathematically represented as:
R = ρ × (L / A)
Where:
R is the electrical resistance of the conductor,
ρ (rho) is the resistivity of the material,
L is the length of the conductor, and
A is the cross-sectional area of the conductor.
The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).

Resistance in a circuit that has 35 mA of current and 5.6 V applied equals.
Answer:
R = 160 Ω
Explanation:
For this problem, we will simply apply Ohm's law to find the resistance in the circuit. Ohm's law is as follows:
Voltage = Current x Resistance
We can solve the law for resistance:
Resistance = Voltage / Current
And now we just plug in our values:
Resistance = 5.6V / 35mA
Resistance = 5.6V / 0.035 A
Resistance = 160 Ω
Hence the resistance of the circuit is 160 Ω.

Where are most plate boundaries?
Answer:
Most plate boundaries are located along the edges of the Earth's tectonic plates. These plates are composed of the Earth's crust and upper mantle, and they move and interact with one another at the boundaries. There are three types of plate boundaries: divergent, convergent, and transform.
Divergent plate boundaries occur where two plates are moving away from each other, typically resulting in the formation of a new oceanic crust. These boundaries are often found along the mid-oceanic ridges, where magma from the Earth's mantle rises up and creates new crust.
Convergent plate boundaries occur where two plates are moving towards each other. These boundaries can take several forms, depending on the type of plates involved. When two oceanic plates converge, one plate is typically subducted under the other, leading to the formation of a deep-ocean trench and the creation of volcanic islands. When two continental plates converge, they can collide and form mountains.
Transform plate boundaries occur where two plates are sliding past each other horizontally. These boundaries are typically found along large faults, such as the San Andreas Fault in California.
Overall, most plate boundaries are located along the edges of the Earth's tectonic plates, where they interact and create the geological features and phenomena that shape the planet.

Sandy soil
Sand (having big particles with big spaces) constitutes the majority of sandy soil.
There isn't much clay or silt in it. Humus is incredibly scarce in sandy soil. In desert regions, you can find sandy soil.
Sandy soil is made up of large particles with large spaces between them.
Sandy soil can be easily plowed and gives plant roots good aeration (air). It is light soil, If left bare, it frequently blows away.
Compared to other soil types, sandy soil is less fertile. Sandy soil's fertility can be increased by incorporating humus in the form of manure.
The ability of sandy soil to retain water is improved by humus, which also supplies vital plant nutrients.

.Block A of mass 30 kg is resting on Block B of 15 kg and both blocks are connected via a
light and inextensible cable, which runs over a light and smooth pulley. Determine the
tension, T, in the cable and the acceleration of Block B, aB, as it moves up the inclined
plane.
The tension in the cable and the net acceleration of the block B are 291.814 newtons and 0.112 meters per square second, respectively.
How to determine the tension and the acceleration of block B
Based of the representation seen in the image, an external force moves the block A downwards and the block B moves upwards and with an net acceleration of same magnitude due to the cable. By Newton's laws we construct the free body diagrams for each mass and that can be seen in the image seen below.
The motion equations are described below:
Mass A
250 N - 0.4 · Na - T + (30 kg) · (9.807 m / s²) · sin 30° = (30 kg) · a (1)
Na - (30 kg) · (9.807 m / s²) · cos 30° = 0 (2)
Mass B
- T + 0.4 · Na + 0.3 · Nb + (15 kg) · (9.807 m / s²) · sin 30° = - (15 kg) · a (3)
Nb - Na - (15 kg) · (9.807 m / s²) · cos 30° = 0 (4)
By (2):
Na = (30 kg) · (9.807 m / s²) · cos 30°
Na = 254.793 N
By (4):
Nb = 254.793 N + (15 kg) · (9.807 m / s²) · cos 30°
Nb = 382.190 N
Then, we have the following system of linear equations:
T + (30 kg) · a = 250 N - 0.4 · Na + (30 kg) · (9.807 m / s²) · sin 30°
T + 30 · a = 295.188
T - (15 kg) · a = 0.4 · Na + 0.3 · Nb + (15 kg) · (9.807 m / s²) · sin 30°
T - 15 · a = 290.127
The solution of the linear system is T = 291.814 N and a = 0.112 m / s².

An electric kettle is used to boil some water. The kettle holds 1.5 litres of water when full and operates from a 230V, 13 amp supply. If all the electrical energy supplied is converted to heat energy, how long will it take the kettle to boil from an initial temperature of 15°C? (The specific heat capacity of water is 4190J/kgK.)
The time taken to heat the water is 1.79 * 10^5 s.
What is the time taken?We know that in this case, the principle of energy transformation holds true. The electrical energy is converted to the heat energy that causes the water to boil.
We then have;
IVt = mcdT
I = current
V = voltage
t = time taken
m = Mass of water
c = heat capacity of water
dT = temperature change
Thus;
230 * 13 * t = 1500 Kg * 4190 * (100 - 15)
t = 1500 * 4190 * (100 - 15)/230 * 13
