Momentum would be the same before and after the collision
Before the collision:
Momentum of the single cart: 1 * 0.50 = 0.50
After the collision
velocity = 0.25m / s
1 * 0.25 + 1 * 0.25 =
0.25 * (1 + 1) =
0.25 * 2 =
0.50
Now new momentum will be 0.5
answer
the same before and after the collision
I think its Mercury because it's the closest to the sun.
Answer:The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
Explanation:
Answer: the golf ball with smooth surface would hit the ground first.
Jusitification:
An analysis of forces show two vertical forces acting on the golf balls.
1) one force is the weight (mg) which is vertical downward
2) the other force is the drag force exerted by the air on the golf balls, and it is vertical upward.
3) the drag force opposes the weight, so the acceleration downward is determined by the difference of the weiight and the drag force, until the balls reach the terminal speed (when the drag force equals the weight).
4) the drag force depends on the shape and area of the object falling. Being the surface of one ball smooth implies that the drag force will be less than the one on the other ball.
5) less drag force implies that the terminal velocity of the smooth ball will he higher, ant then it will hit the ground first.
An Independent Group/ between-subjects design differs from a within-subjects design in that a between-subjects design. The correct option is B.
<h3>What is independent measure design?</h3>
Studying between subjects (or between groups): As various subjects are used to test each condition, each subject is only exposed to a single user interface. internal topic (or iterative measurement) The same topic evaluates every circumstance (that is, all user interfaces).
Each participant in a topic or intergroup design only encounters one condition, and the group differences between individuals under various conditions are compared. The in-subject design, in which every participant is exposed to every condition, is the antithesis of this.
