This time the pendulum is 1.09 m long. Suppose you start with the pendulum hanging vertically, at rest. You then give it a push so that it starts swinging with a speed of 1.47 m/s. What maximum angle (in degrees) will it reach, with respect to the vertical, before falling back down? D) 26.0 degrees 2 15.6 degrees 3 46.8 degrees 4 36.4 degrees
Refraction of Light
Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.
Angle of Refraction
Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic radiation whereas part of it is perceived by humans. Visible spectrum defined by humans lies in a range of 400 to 700 nm wavelengths.
Index of Refraction of Diamond
Diamond, the world’s hardest naturally occurring material and mineral known, is a solid form of the element carbon. The atoms are arranged in a crystal structure called diamond cubic. They exist in a huge variety of colours. Also, they are one of the best conductors of heat and have a very high melting point.
There are 4 parts (a, b,c , d) please answer part D (the second image)
![A simple pendulum is suspended from the ceiling by
means of a string of length 2.41 m. Assume that there is
no friction or air resistance. Suppose you were to release
the pendulum from rest, starting from an angle of 32.0
degrees with respect to the vertical, as shown. What will
be the speed of the pendulum at the instant it swings
through its lowest point (that is, when it s momentarily
hanging vertically)?
OK, once again we have a pendulum, this time of length
1.03 m, which you release from rest at an angle of 52.4
degrees to the vertical. What will be the speed of the
pendulum at the instant it reaches an angle of 26.2
degrees above the vertical?

This, the length of the pendulum is 1.24 m. Now you start
with the pendulum at 11.4 degrees with respect to the
vertical, but rather than releasing it from rest, you give it a
push downward. It swings to the other side, and reaches a
maximum angle of 56.9 degrees with respect to the
vertical. What must have been the initial speed of the
pendulum just after you pushed it?
3.25 m/s
C)
