Answer:

Explanation:

When we say anything is a wave, what exactly do we mean? The most intuitive and straightforward wave to envision is a water wave. A motion, more specifically, is a disturbance that propagates or travels away from its source. Water waves are caused by a disruption in the water's surface, such as a rock tossed into a pond or a swimmer splashing the surface continuously. The noise for sound waves is a rise of air pressure, which may be caused by the oscillating cone within a speaker. There are many kinds of disturbances in earthquakes, including surface disturbances and pressure disturbances under the surface. Even radio signals are best deciphered by using a comparison of sea waves Water waves are helpful to visualize since they are more than just a mental picture. The amplitude, period, frequency, and energy of water waves are all the same as they are for all waves. A small set of underlying principles can be used to describe all wave characteristics.

A container holds 35.8 moles of gas under 10.0 atm of pressure at 70.0 C. What is the volume of the container? 20.6 L 101 L 2080
Pavlova-9 [17]

PV = n RT
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin

 
V= (n RT) / P = 35.8 x 0.082 x 343.15   / 10 = 100.7 ≈ 101 L

 V = 101L

What is the pH of a solution with a H+ ion of 2×10-¹²?​
kap26 [50]

Answer:

11.7

Explanation:

The pH is the negative logarithm of the concentration of H+ ions. If the concentration is 2×10-¹² the the pH will be -log(2×10-¹²) which is 11.698 which can be round up to 11.7.
