<span>If your speed change from 10 km/h to 6 km/h,you have a negative acceleration</span>
Answer:
C = Q / V
Q = C * V = 2.5 F * 3 V = 7.5 Coulombs (assuming the batteries are in series)
N e = Q where N is the number of electrons and e the electronic charge
N = 7.5 / (1.60E-19) = 4.7E19 electrons
or 4.7 * 10^19 electrons
Answer:
the only way to change the velocity of an object is to apply force.
Explanation:
Newton’s first law of motion says an object will continue to move with the same velocity unless acted on by an external force.
You sketch a water molecule and show a partial positive charge on the two Hydrogen atoms and a partial negative charge on the oxygen atom.
Answer:
The equivalent or total resistance of the circuit is 6
Explanation:
6 &6 are in series
6+6=r
r= 12
1/Rtotal= 1/12+1/2
1/Rt=2/12=1/6
Rt=6
