Answer:
=−2.451 330 152 1*10^27J
Explanation:
The electric potential=the Voltage * Charge:
E = VQ
V = 1.53x10^8 V (positive, because the cloud has a higher potential)
Q = -1.60217657 x10^19 C (the charge of an electron)
E = (1.53x10^8 V )* (-1.60217657 x10^19 C)
E=−2.451 330 152 1*10^27J
The negative sign indicates that the potential energy is decreased by the movement of the electron.
Answer:
Explanation:
Given
initial velocity 
Distance traveled before stopping 
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling 
negative sign indicates it is deceleration
Answer:
<em>85.12 μAmp</em>
<em></em>
Explanation:
The battery power output = 17.15 Amp-hr
If the battery is to last 23 years, we have to calculate how many hours there are in 23 years
in one year there are 24 hours x 365 day = 8760 hrs
in 23 years there are 23 x 8760 = 201480 hours
maximum current to be drawn from the battery = (17.15 Amp-hr) ÷ (201480 hours) = 85.12 x 10^-6 Amp = <em>85.12 μA</em>
Answer:
The volume of 3200 kg of petrol is 4 m^3.
