Answer:
Yes
Explanation:
By definition, the circumpolar stars are those stars which neither rise nor set. They trace a complete circle around the pole star. That means they are always above the horizon. They might not be visible during the daytime because of Sunlight and atmosphere but that doesn't mean they are below the horizon. They will still be above the horizon but will be visible only during the night time.
Answer:
The potential difference between the ends of a wire is 60 volts.
Explanation:
It is given that,
Resistance, R = 5 ohms
Charge, q = 720 C
Time, t = 1 min = 60 s
We know that the charge flowing per unit charge is called current in the circuit. It is given by :
I = 12 A
Let V is the potential difference between the ends of a wire. It can be calculated using Ohm's law as :
V = IR
V = 60 Volts
So, the potential difference between the ends of a wire is 60 volts. Hence, this is the required solution.
Answer:
statement 1
Explanation:
When mass increases,KE increases and when mass decreases, KE also decreases
It's commonly referred to as an electric current.
