Answer:We can solve this using the Law of Conservation of Momentum. If both marbles are in our system, the initial momentum should equal the final momentum.
The initial momentum can be solved for as so:
* + =
(0.06)(0.7) + (0.03)(0) = 0.042 [kg * m/s]
So if the system has an initial momentum of 0.042, it should have the same final momentum.
(0.06)(-0.2) + (0.03)() = 0.042
(0.03)() = 0.54
() = 18 [m/s]
Explanation:
Melting and pressure.
Weathering and erosion affect any surface rock and make sedimentary rocks, heat and pressure make metamorphic rocks, and melting and cooling make igneous rocks. Melting and pressure is not a step.
Answer:
0.65812
Explanation:
m = Mass of suitcase = 16 kg
= Incline angle = 40°
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration of the block = 1.36 m/s²
f = Frictional force
The normal force is given by
In x direction
Frictional force is given by
The coefficient of kinetic friction between the suitcase and the ramp is 0.65812
That is true.
In the solid state the molecules of water have the lowest energy content.
To pass from solid state to liquid stated water needs to gain some energy to increase vibration and motion of the molecules and reach a higher energy states.
To pass from liquid state to vapor (gaseous state) the molecules of water have to gain more energy to increase more the motion of the molecules and reach a more energetic stated.
Then you can think that when the water vapor becomes liquid (droplets) it needs to release some energy.
The droplets formed on a glass of ice water is an example of water condensation, one of the processes of the water cycle.
The droplets on the external surface of a cold glass are the result of condensation of water.
Condensation is the pass from vapor state to liquid state. As whe have stated, when water passes from vapor state to liquid state it has to release energy because liquid state is lower in energy than vapor (the molecules in water experiment slower motion than molecules of vapor).
