If there's nothing else connected to the battery except the 3-ohm resistor, then the question is defective and the correct answer is not on the list.
With 12v connected across the resistor, the current through the resistor is
I = (E/R) = (12/3) = 4 Amperes.
The power generated inside a resistor is
P = (E x I) = (12v) x (4 A) = 48 watts
amount of heat is removed to lower the temperature of 80 grams of water from 75ºC to 45ºC with specific heat of liquid water is 4.18 J/gºC
= 4.18 J/gºC * 80g * (75-45)ºC
= 10032J
Answer:
it's b
Explanation:
it's b cause ik I'm not wrong at these I did this when I was a kid and never got it wrong so it's b and will be cause b is the right answer so b it is
My best hobby is driving. Driving has something to do with Newton's first law of motion, which states that an object will continue to be in its state of rest or in uniform motion in a straight line unless it is acted upon by an external force. This law means that an object will continue to be in motion in the same direction unless it is acted upon by a force. Newton's first law of motion is also called the law of inertia.
I usually experience the law of inertia when I am driving my car.
Every morning, for me to move the car from its state of rest to a state of uniform motion, I have to switch on the ignition, which represent an unbalanced force that move the car out of its states of rest. When I am driving, the car continue in motion and in the same direction, unless I apply the brake. The application of the brake is an example of applying an unbalanced force to stop a body in motion.
