A spring with a spring constant k of 44 N/m is stretched a distance of 30 cm (0.3 m) from its original unstretched position. What is the increase in potential energy of the spring?

If there is just one force acting on an object, does its work necessarily result in an increase in kinetic energy? Explain. (Select all that apply.) 1.Yes, when a force does work on an object it always results in an increase in kinetic energy. 2.The work...

Find the electrical potential energy (EPE) of three point charges placed as follows on the x-axis: +2.0 μC at x = 0, +3.0 μC at x = 20 cm, and +6.0 μC at x = 50 cm. Take the (EPE) to be zero when the charges are far separated.

the formula for the area of a trapezoid is a=1/2h(b1+b2) are the are the length of the bases, and is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?

=[1/(1-sin x)]*[1/1+sin x] =1/(1-sin x)*(1+sin x) =1/1-(sin x)^2 :using Pythagorean identity =1/(cos x)^2 :using reciprocal identity =(sec x)^2

THANKS FRANKU!! i got 100%! :D

ya thanks ola

how to do it pls
