Static Electricity
Explanation:
Most likely, in the room, Jim was building up static electricity by friction with the floor, which he released upon contact with a metal object.
Answer: 10.7 moles
Explanation: Hydrogen gas exists as a diatomic gas (H2) Hence, the Molar mass of one mole of hydrogen gas is 1 x 2 = 2 g. To find the number of moles from the mass take the weight and divide is by the molar mass of the molecule. So in this case, 21.4/2 = 10.7 moles
Answer:
Am I supposed to answer these on brainly?
Explanation:
Body waves travel through the interior of the Earth. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. the surface of the Earth).
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
P-waves are compression waves. They can propagate in solid or liquid material.
S-waves are shear waves. They only propagate in solid material.
By studying the trajectories of S-waves, scientists could prove that the Earth had a liquid outer core.
