Anions: negatively charged atoms
Cations: positively charged atoms (CAT-ions are PAWS-itively charged)
Anode: positively charged electrode that allows electrical current flow (positive end of battery)
Cathode: negatively charged electrode that allows electrical current flow (negative end of batter)
In a Horsehoe magnet, maximum magnetic field is concentrated between the poles.
Hope this helps!
Explanation:
Mass of the ball, m = 0.058 kg
Initial speed of the ball, u = 11 m/s
Final speed of the ball, v = -11 m/s (negative as it rebounds)
Time, t = 2.1 s
(a) Let F is the average force exerted on the wall. It is given by :
F = 0.607 N
(b) Area of wall, 
Let P is the average pressure on that area. It is given by :
P = 0.202 Pa
Hence, this is the required solution.
Muddy environments because it is soft and malleable.
Velocity = distance / time
So: The time in which the wave propagates through air which is its medium along with the distance the wave travels so a point are needed to give us our velocity.
In this case we only have velocity and time
So lets rearrange our equation to fit what we are solving for: distance
Vt = d
Now plug in our values:
(330)(0.40) = d
d = 132 m
So the distance between you and your neighbor is 132 m as they perceive the sound at time t= 0.4 and a speed of sound of 330 m/s.
