Answer:
The potential at a distance of 0.9 m is 266.67 V.
Explanation:
Charge = Q
Potential is 400 V at a distance 0.6 m .
Let the potential is V at a distance 0.9 m.
Use the formula of potential.
Energy used by the element = 6336000 j
The electrical energy is given by
E= V i t
V= voltage= 110 V
i= current=3.2 A
t= time= 5 h= 5 (3600)= 18000 s
so energy= E= 110 (3.2)(18000)
E=6336000 J
Answer:
600m
Explanation:
30×20 at a constant speed is 600m.
Mass = Density * Volume
Density = 19.3 g/cm³
Volume = 24 cm³
Mass = Density * Volume = 19.3 g/cm³ * 24 cm³ = 463.2 g
Mass = 463.2 g
