Answer:
Electric potential, E = 2100 volts
Explanation:
Given that,
Electric field, E = 3000 N/C
We need to find the electric potential at a point 0.7 m above the surface, d = 0.7 m
The electric potential is given by :


V = 2100 volts
So, the electric potential at a point 0.7 m above the surface is 2100 volts. Hence, this is the required solution.
 
        
             
        
        
        
The resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms)
Explanation:
In the United States Of America the standard voltage is 120 v and their frequency is 60 Hz
Standard wall outlet voltage is 120 V
The current in the lamp is 0.5 ampere
 Resistance (R) = V/ I
       = 120/0.5
       = 240Ω (ohms)
Thus the resistance of the lamp plugged in to a standard wall outlet with a current of 0.5 amps is 240 Ω (ohms).
 
        
             
        
        
        
Since the circuit is incomplete or not closed, no current flows in the circuit. as per ohm's law , Voltage is directly proportional to current and is given as
V = Voltage = i R where i = current , R = resistance 
as no current flows in the circuit, i = 0 
the resistance R can not be zero. hence 
V = 0 (R)
V = 0 Volts
so the magnitude of the Voltage is zero Volts
 
        
                    
             
        
        
        
The speed is 0.2 meter per minute.
There is not enough information given in the question to determine the velocity.
