Voltage, V = IR
Where I is current in Ampere, R is Resistance in Ohms.
V = 9A * 43 Ω
V = 387 V
Answer:
<em>The distance covered by comet is </em>
Explanation:
Speed is defined as the rate of change of distance with time. It is given by the equation speed= 
Thus distance= 
In this problem it is given that speed of comet= 
time travelled by the comet= 4 hours
Thus distance= 
= 
=
