The main difference between absolute and apparent magnitude is that apparent magnitude measures the observed brightness of an object from any point, whereas absolute magnitude calculates the brightness of the object as seen from a standard distance away from the object.
Alice and Jim will put 2,400 Joules of energy into the situation,
and 1,800 Joules of energy will come out in a useful form.
The efficiency of the whole process will be
1800 J / 2400 J = 3/4 or 75% .
Answer:
Graph 1 matches with B, 2 with A, and 3 with C.
Explanation:
Graph 2 shows a car whose distance part of the graph is not going up or down, while the time going up. That means that the car is stopped. Graph 1 shows a straight line, meaning that the car is traveling at a constant speed. Graph 3 is a curved line, meaning the speed of the car is changing somehow, and since the line is becoming more horizontal, the car is getting slower.
Answer:
slope
Explanation:
The slope is how how steep the line is.
