Hello!
<span>The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the gas phase.
The word "gas" was created by the Netherlandish scientist Jean Baptista van Helmont from the Latin word "chaos". The gas phase consists of molecules with high kinetic energy, that adopt the shape of the container and tend to expand. The molecules are essentially free, and the gravitational pull on them is negligible.
Have a nice day!</span>
Answer:
4.7 × 10⁵J
Explanation:
E = I * a * t
80% = 0.80
25cm = 0.25m
52cm = 0.52m
0.90h = 3240s
E = (0.80)(1400)(0.25 * 0.52)(3240)
= 4.7 * 10⁵J
B: 1 trillion distributed across the universe. If I remember correctly.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
