Leash a block of 0.5 kg down the entire length of an inclined plane forming a name of 37 ° with the horizontal. Friction with th
e plane is negligible. upon leaving the inclined plane, the block compresses a spring a spring on a polished horizontal surface. if the length of the plane is 2.5m and if the spring is and compressed by 60 cm what is the elasticity constant of the spring?
The potential energy of the block is given by: V = m*g*h m mass g = 9.81m/s² h height
The potential energy of a spring is given by: V = 0.5 * k * x²
k spring constant x compression of the spring
If the block starts from rest it has potential energy, but no kinetic energy. As it slides down the incline potential energy is converted into kinetic energy. When the block hits the spring the kinetic energy is converted into spring's potential energy. If the spring is fully compressed and the block is at rest again, the block has transferred all its energy into the spring. No energy is lost. So we can write:
m * g * h = 0.5 * k * x²
m = 0.5 kg g = 9.81 m/s² h = 2.5m * sin 37° = 1,5 m x = 0,6 m
Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.
Idk if this helps but plz mark brainliest if it does
Celina should perform the following method to get pure water:
Boil the water in a pan, as the water boils it changes into gas (water vapours) these vapours should be cooled down through the process of condensation which changes gas into liquid form, Through this process germs would be killed due to high temperature and the salt will remain in the pan as salt has higher boiling point than water,
Have a universal record base. Everyone is able to understand the data compiled since the same measurement systems are being used around the world. This is just to simplify all of the information.
