Answer:
Voltage = current * resistance
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.

) Potential difference is the difference in electrical potential between two points. Which term can also be used to describe potential difference?
Answer:
It is also called voltage.
Explanation:
Voltage in a circuits can be define as difference between two points that enable it to push a charge or current in a conducting loop there by causing light. This can also be defined as the workdone that is required per unit of charge or current to cause a motion of a test charge between the two points.

Answer:
The balanced chemical equation is 1SnO2 + 2H2 --> 1Sn + 2H2O.
Explanation:
The equation is now balanced because both sides have an equal number of reactants and products.
There is 1 Sn on each side, 2 O on each side, and 4 H on each side.
If the mass of an object on earth is 18 grams, what would the mass of the same object be in the Moon
Answer:
18 grams
Explanation:
The mass of an object is the object's fundamental property. It is the amount or quantity of mater in the object. Irrespective of the object's location or the gravitational force applied on the object, the mass of an object remains the same. In other words, the mass of an object is the same everywhere.
The mass should however not be confused with its weight which depends on the mass and the gravitational force applied on it.
In summary, whether on earth or in the moon, the mass of an object remains the same. If the mass of the object is 18 grams on earth, it will also be 18 grams in the moon.

#CARRY ON LEARNING #MARK BRAINLITSThe diagram shows a compressed spring between two carts initially at rest on a horizontal frictionless surface. Cart A has a
mass of 2 kilograms and cart B has a mass of 1 kilogram. A
string holds the carts together. After the string is cut and the
two carts move apart, the magnitude of which quantity is the same for both carts?
O inertia
O momentum
O velocity
O kinetic energy
A.2 kg
В.1 kg
Answer:
momentum
Explanation:
the impulse is equal for both carts, the momentum for both carts is zero both before the string is cut and after it is cut
After the string is cut and the carts move apart, the magnitude of momentum is the same for both carts. Hence, option B is correct.
What is Momentum?Momentum is the result of a molecule's mass and velocity. Being a vector quantity, momentum possesses both magnitude and the direction. As according to Isaac Newton's second equation of motion, the force applied on a particle is equivalent to the time change in velocity.
According to Newton's 2nd law, if a particle is exposed to a constant force for a specific period of time, the result of the force and time (referred to as the impulse) is equal to the difference in momentum. In contrast, hand, a particle's momentum is a measurement of the amount of time needed for a consistent force to put it to rest.

Marvin lifts a box over his head. The work done on the box is- -Negative work -No work -Positive work
Answer:
Positive work
Explanation:
When work and the exerted force are in the same direction, then the work done is positive.
In the question, we understand that Marvin lifts a box up (i.e. over his head). The force to lift the box acts in the upward direction and the work done itself is also in the upward direction (from the floor to Marvin's head).
Since these two are in the same direction, then we can conclude that the work done is positive.
Which best describes a saturated solution?
A
Additional solvent is able to be dissolved in the solute.
B
Additional solute is able to be dissolved in the solvent.
С
The maximum amount of solvent is dissolved in the solute.
D
The maximum amount of solute is dissolved in the solvent.
The maximum amount of solute is dissolved in the solvent. The correct option is D.
What is a saturated solution?A saturated solution is a type of solution where the maximum amount of solute has been dissolved in a solvent, at a specific temperature and pressure, such that any additional solute added will not dissolve.
A saturated solution is a solution in which the maximum amount of solute has been dissolved in the solvent at a specific temperature and pressure. Any additional solute added to the solution will not dissolve and will instead settle at the bottom of the container as solid particles.
The concentration of a saturated solution is at its maximum level and cannot be increased further unless the temperature or pressure is changed.
Therefore, the correct option is D.

When beavers inhabit an area, they cut down trees and construct beaver dams, which slow the flow of rivers or streams. Which of the following variables is NOT going to change as a result of the long-term presence of beavers in an area?
F. the number of tree species in the area
G. the types of fish present in the river or stream
H. the amount of rainfall received in summer months
I. the amount of sunlight that reaches the forest floor
Answer: H
Explanation:
When beavers dam a stream they slow the movement of water. Behind the beaver dam, a pond of still water is formed. This pond is then colonized by animals and plants that typically live in lakes rather than streams.

what is the definition of gravity in simple terms?
Answer:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects
1 : A force of attraction that tends to draw particles or bodies together.
2 : The attraction of bodies by the force of gravity toward the center of the earth.
3 : Great seriousness.
What is the magnitude of the resultant of two forces 20 Newton and 15 Newton at 90 degrees to each other
Answer:
the magnitude of the resultant of two forces is 25 N.
Explanation:
Given;
first force, F₁ = 20 N
second force, F₂ = 15 N
the angle between the two forces, θ = 90⁰
The resultant of these two forces is obtained by applying Pythagoras theorem;
R² = F₁² + F²
Where;
R is the resultant force
R² = 20² + 15²
R² = 625
R = √625
R = 25 N
Therefore, the magnitude of the resultant of two forces is 25 N.
What is the density of a 2.5-cm3 glass
marble that has a mass of 7.5 g?
Explanation:
Density=mass/volume
Density=7.5/2.5
density=3g/cm^3
The density of a 2.5-cm3 glass marble that has a mass of 7.5 g is 3g/cm^3.
What do you mean by density ?The density of a material is the measure of how tightly it is packed together. It is expressed as mass per unit volume.
Density Symbol: D or Density Formula: = m/V, where is the density, m is the object's mass, and V is the object's volume.
Density is the amount of "stuff" in a given amount of space. A block of the heavier element lead (Pb), for example, will be denser than a block of the softer, lighter element gold (Au). A Styrofoam block is less dense than a brick. It is expressed in terms of mass per unit volume.
Density = mass / volume
Density = 7.5 / 2.5
density = 3g/cm^3
Thus, The density of a 2.5-cm3 glass marble that has a mass of 7.5 g is 3g/cm^3.

In what way are networks different from other types of electrical wiring?
Answer:
Networking cables are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers, scanners etc. Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network's physical layer, topology, and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet).
There are several technologies used for network connections. Patch cables are used for short distances in offices and wiring closets. Electrical connections using twisted pair or coaxial cable are used within a building. Optical fiber cable is used for long distances or for applications requiring high bandwidth or electrical isolation. Many installations use structured cabling practices to improve reliability and maintainability. In some home and industrial applications power lines are used as network cabling.
