Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
Answer: A. True
Answer:
650.
Step-by-step explanation:
ok so first multiply the Length and the width of the rectangle together to get its area, which is 500.
to find the area of the triangle, just multiple the length times the width (15 x 20) and divide it by two. You should get 150.
Add 150 and 500 together, and that's your total area:
650.
Have a nice day dude
Very nice question. glad to see you’re exploring your education with gibberish’
42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
Step-by-step explanation:
y - y1 = m (x - x1)
(y - y1)/m = x - x1
x - x1 = (y - y1)/m
x = (y - y1)/m + x1
therefore, answer is option C
