The most widely used renewable energy source is hydropower. While this has many benefits, it also causes many environmental concerns when the dams get built.
Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather. Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.
It’s Microgravity it says it on NASA‘s website
We determine the mass of the metal in grams by weighing it using the balance.
Next we obtain the volume of the metal by measuring its displacement with a graduated cylinder and water in the following way:
1.measure amount of water in the graduated cylinder.
2. Place metal into the graduated cylinder
3. Measure the amount of water in the graduated cylinder
4. Subtract step 1 from step 3. The difference is the metal's volume.
Once we have found out the mass and the volume then we calculate the density using the formula:
Density = Mass/Volume.
We then check our answer from the known densities of metals in the table of densities that has been provided and determine the identity and purity of the metal by how close our answer is to the most probable value in the table.
