The graph shows the volume of oil (L litres) in a tank at time t seconds. a)find the gradient of the graph b)explain what this gradient represents. the graph intersects the volume axis at L=2 c)explain what this value represents
Answers
Answer/Step-by-step explanation:
a. Using two points on the line (0, 2) and (4, 12), find the gradient:
Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5
Gradient = 2.5
b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.
i.e. 2.5 litres per second
c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.

(-2,5)
Step-by-step explanation:
because 2 units to left of the y axis makes it a negative and it makes it on the z axis so you get negative 2 then 5 units above the x axis gets just 5 so that's how you get (-2,5)

The fourth choice, Pink, is the correct answer.
Step-by-step explanation:
The first two options intersect, therefore the intersection is the solution. The third set of lines may seem like one line, however since we are dealing with two linear equations, it can be presumed that those are two lines on top of one another, therefore it has infinite solutions. The last option remaining is Pink, in which the lines are parallel and therefore will never intersect, making them have no solution.
Trig function - find the exact value
Answers
Answer:
3/5
Step-by-step explanation:
We can find ∅ by using the tangent function since we have the opposite and adjacent sides of ∅.
tan(∅)=1/2
tan^-1(tan(∅))=tan^-1(1/2)
∅=26.57
Since we are looking for cos(2∅), then we have cos(2(26.57))=cos(53.14)≈0.6
So the exact value is 3/5

How do electromagnets differ from regular magnets?
Answers
Answer:
Permanent Magnets and Electromagnets: What are the Differences? A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. ... An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it.
Step-by-step explanation:
Electromagnets differ from regular magnets in that they require an electric current to generate a magnetic field.
Regular magnets, also known as permanent magnets, possess an inherent magnetic field due to the alignment of their atomic or molecular structure. They do not require an external power source.
On the other hand, electromagnets are made by wrapping a coil of wire around a magnetic core and passing an electric current through the wire. The electric current creates a magnetic field, and the strength of the magnetic field can be controlled by varying the current.
One key advantage of electromagnets is their ability to be turned on and off by controlling the electric current. This feature allows for a wide range of applications, such as in electric motors, generators, speakers, magnetic levitation systems, and more, where the magnetic field needs to be controlled or modulated. In contrast, regular magnets have a constant magnetic field that cannot be easily manipulated.
