A or B... I mean when lava is poured out to the surface, heat and soilica content may play a role... That's what I think sorry :(
Answer:
the current flowing in the circuit is 0.1 A.
Explanation:
Given;
potential difference, V = 12 V
resistance of the circuit, R = 120 ohms
The current flowing in the circuit is calculated as;
V = IR
I = V/R
where;
I is the current flowing in the circuit
I = 12 / 120
I = 0.1 A
Therefore, the current flowing in the circuit is 0.1 A.
Answer:
the acceleration of the train is - 8 m/s² since it is decelerating as the influence of the brake comes to stop
Explanation:
Mass of the block = 2.0 kg
Value of gravity = 9.81 m/s^2
Distance upto which the mass is lifted = 15 meters
Time taken to lift the mass of the block = 6.0 seconds
Now we already know
Work Done = Mass * Gravity * Distance
= 2 * 9.81 * 15
= 294 Joules
Then
Power Output = Work Done/Time
= 294/6
= 49 Watts
So the power output of the electric motor is 49 watts.The correct option among all the options given in the question is option "4".
