Some potential energy was converted into thermal energy due to friction. The acceleration due to gravity became smaller as the box slid down the ramp.
Answer:
In very hot, humid weather you might feel the air is heavier because moving around seems to take more energy than on dry days. Sticky days probably feel “heavier” because heat and high humidity slows the evaporation of perspiration, your body grows hotter and this saps your strength
Explanation:
The answer is B because none of the other options are true.
The element is most likely PHOSPHORUS.
Phosphorus is an element with an atomic number of 15. The electronic configuration of the element is 2,8,5. This configuration implies that, each atom of phosphorus has three sub shell, the first sub shell has 2 electrons, the second has 8 electrons while the outermost sub shell has 5 electrons. The electrons in the outermost shell are also called the valence shell. Thus, phosphorus has 5 electrons in its valence shell.
