Which are examples of a medium? water and air amplitude and wavelength crests and troughs compressions and rarefactions
umka21 [38]

Answer:

water and air

Explanation:

  • A wave is a transmission of a disturbance from one point or the source to another  point.
  • Transmission of a wave occurs through a material medium or a vacuum. Therefore a medium is the material through which a wave travels through.
  • The medium may be in gaseous form, slid form or liquid form. Therefore water and air are example of medium of transmission of a wave.

RideAnS [48]
<h2>When Transferring Flammable Liquids - Option A</h2>

To create a pathway for the liquid to flow easily is a correct reason to physically connect objects with a bond wire when transferring flammable liquids. Physically connect the two conductive objects together with a bond wire to eliminate a difference in static charge potential among them. The bond wire is attached between the containers in the process of flammable filling liquid actions except for a metallic path is found.

Please write a paragraph (5 sentence minimum) that describes convection in Earth's atmosphere.
ExtremeBDS [4]

Answer:

Earth's crust is covered by a densed air blanket called atmosphere. Due to which we feel warm even during night when there is no sun. The air near the atmosphere is less dense compared to the air near our crust. Similarly we can experience high pressure near the atmosphere comparelatively we experience less pressure near crust. The presence of atmosphere above us makes the wind fair sometimes stromy and also helps in pteperation of wind and breezes in earth's surface.

An electron travels 0.01 m across an electric potential difference of 6 x 10^6 V. What is the force exerted on the electron? Typ
JulijaS [17]

Answer:

9.6\cdot 10^{-11}N

Explanation:

The force experienced by a charged particle immersed in an electric field is

F=qE

where

q is the charge of the particle

E is the strength of the electric field

For a uniform field, we can write

E=\frac{\Delta V}{d}

where

\Delta V is the potential difference

d is the distance travelled

So we can rewrite the force as

F=\frac{q\Delta V}{d}

In this problem:

q=1.6\cdot 10^{-19}C is the charge of the electron

\Delta V=6\cdot 10^6 V is the potential difference

d = 0.01 m is the distance covered

Substituting, we find the force:

F=\frac{(1.6\cdot 10^{-19})(6\cdot 10^6)}{0.01}=9.6\cdot 10^{-11}N
