The cathode and anode are hooked up to an electrical circuit The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. Hope this helps :)
Kinetic energy= .5 x m x v^2
KE=.5 x 4.2 x 3.85^2
KE=31.13
Answer:
the ball is travelling very fast and the player can get injured if he doesn't wear gloves
Explanation:
To keep the energy going every day
Answer:
A, 0.050 Hz
Explanation:
1) Frequency = speed divided by wavelength
time is 2* 60 = 120 seconds
distance = 6 wave lengths
speed = distance divided by time
speed = 6 wave lengths divided by 120
Hope this helps!
