A simple pendulum consisting of a 1. 0m long string and a 0. 20kg bob is pulled to the side so that the string makes an angle of 20° with the vertical. If the gravitational potential energy of the bob-earth system is zero at the lowest point of the pendulum’s arc, the angle at which the gravitational potential energy of the bob-earth system is equal to the kinetic energy of the bob is most nearly.

.how are johansson’s photographs different than most others?

because his photographs are based on photo realism. photos where you will need a brief moment to think to figure it out the trick of it.

2.what makes his photographs seem real?

sometimes the perspective is the illusion. different pieces of reality and put them all together. and things that we don’t even think about.

3.what rules does johansson follow in his photography?

photos combined should have the same perspective. photos combined should have the same type of light.making it impossible to distinguish where the different images begin and end by making it seamless.

4.which of johansson’s creations did you like the best? why?

the big fish under the water with the house on top of the rock. because it's really hard to create pictures like that one, it requires a very precise moment to snap the picture
