Answer:
The objects must be different temperatures.
Explanation:The objects must be different temperatures. eat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3. Which factors affect heat transfer between a warm and a cool substance?
Answer:
average would be all your speeds divided by certain amounts of time and divided by the amounts of time you divided it into ///////// constant speed is is no going any faster or slower no acceleration.
Explanation:
constant speed means that there is no acceleration. For example a car moving at 50 mph is going at a constant speed, but a car that is standing still on the road and speeds up to 50 pmh is in a constant state of acceleration. Once the car reaches 50 mph there is zero acceleration and you are moving at a constant speed. Constant speed
The average speed of an object is the total distance traveled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity. Average speed
Answer:
21.23 cm
Explanation:
Being that the mass of the bar is equal on both sides, the moment produced by the masses cancel each other out, so you can just look at the hanging masses.
Sum of the moments about the fulcrum = 0... I'll say that moments produced on the 4.6 kg side are positive
0 = 4.6kg * g * 12.0 cm - 2.6kg * g * x
g's cancel. solve for x
x =( 4.6 * 12) / 2.6
x = 55.2 / 2.6
x = 21.23cm
so 2.6kg mass should be pivoted at a distance of 21.23 cm from pivot.
