Find the resultant of 150N and 200N acting at an angle of 30?
Here is how to solve this. Decide on a direction for each vector. Use your scientific calculator to do a polar-to-rectangular conversion - i.e., separate each vector in horizontal and vertical components. (Check your calculator's manual on how to carry out a polar-to-rectangular conversion.) Add the vectors by components. Finally, convert back to polar (rectangular-to-polar conversion, on your scientific calculator).
How can I read an equation?
Let's start at the very beginningA very good place to startyou need to convert each symbol into a word.
What does rectangular prism look like with 12 cubes?
A rectangular prism has two bases, each of which is a rectangle, and four rectangular sides. The 12 cubes are the same as the rectangular prisms, except that each of the rectangles is a square.
How do you calculate imaginary numbers?
Usually you don't use pure imaginary numbers, but complex numbers - numbers that have a real and an imaginary part. To add and subtract complex numbers, you add and subtract the components (just like any other vector). That is, you add (or subtract) the real part and the imaginary part separately. To multiply them, you multiply the components, just like you would multiply any two polynomials - multiply each part of the first number by each part of the second number. Remember that i2 = -1. Combine the real and the imaginary parts. To divide, consider the division as a fraction, and multiply top and bottom by the complex conjugate. For example, if you are dividing by (2 + 3i), multiply numerator and denominator by (2 - 3i). This will convert the denominator into a real number. Another way to multiply is to convert the complex numbers into polar coordinates (absolute value, i.e., length, and angle). Multiply the absolute values (which are real numbers) together, and simply add the angles. For example, (3 angle 30°) x (4 angle 20°) = (12 angle 50°). You may need to convert the result back to rectangular coordinates in the end. Note that scientific calculators usually have an option to quickly convert from rectangular to polar, or polar to rectangular, coordinates.
How many cubic feet are in 5 x 15 x 20?
If those are feet, and you are talking about a rectangular box, then just multiply the numbers. If the numbers are any other unit (and you are still talking about a rectangular box), then convert each of the numbers to feet first.
What is the source of electrical power on the iss?
Those huge flat rectangular panels full of solar cells sticking out on each side of the ISS are. They convert sunshine into electrical energy.
How many edges does a rectangular triangle have?
A rectangular triangle is an oxymoron! A triangle cannot be rectangular and no rectangular shape can be a triangle. The two words contradict each other.
How many perpendicular rectangular faces does a rectangular prism have?
A rectangular prism has six faces, and each of them is perpendicular to four others.
What is the number of congruent rectangular faces on a rectangular prism?
There are three pairs of faces of a rectangular prism, each pair has the same dimensions.
How many vertices's in a rectangular cube?
8, one for each corner; all cubes are rectangular.
How a cube and a rectangular prism alike?
A cube is a rectangular prism in which each edge is of the same length.
How is a cube and rectangular prism the same?
A cube is a special case of a rectangular prism. If each edge of a rectangular prism were of the same measure, then it would be a cube.
