Please help Brainliest for best answer! A long rope with a heavy ball tied to its end is attached to the ceiling. The ball-pendulum is pulled back 10 degrees from vertical and released. When the ball reaches its lowest point it has a speed of 2.0 m/s. Determine the length of the rope and the period of oscillation for this ball-pendulum system? For an extra challenge choose another angle (less than 15 degrees) and show that the period remains the same even though the height h and velocity v differ.

0.19 m/s and 0.45 m/s

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
