Answer:
Solubility
Explanation:
Material becomes soluble in solvent and disappears.
Answer:
A.
Explanation:
The speed or celerity of deep-water waves increases with increasing water depth.
With increase in depth, the pressure inside the increases as p=ρgh.
And with this increase in pressure force associated with waves increase because force is directly proportional to the pressure. Now greater the force greater will be accleration and greater velocity is obtained.
Answer:
The planet will move from east to west for a couple of months in the night sky.
Explanation:
Retrograde motion is an optical effect due to the fact that Earth rotates more quickly than the planet that apparently has a retrograde motion in the sky.
For example, Saturn has a slower speed in its orbit around the Sun. That means that the Earth will pass it, and that will give the effect that the planet is moving backward. That same scenario can be seen between two cars on a highway, the faster car will see the slower car when it passes as it is moving for a short fragment of time in backward.
Remember that the planets in the night sky move from west to east, in the case of a planet with retrograde motion, it will move from east to west for a couple of months.
Answer:
Part a)
Part b)
v = 3.64 m/s
Part c)
Part d)
Explanation:
As we know that moment of inertia of hollow sphere is given as
here we know that
R = 0.200 m
now we have
now we know that total Kinetic energy is given as
Part a)
Now initial rotational kinetic energy is given as
Part b)
speed of the sphere is given as
v = 3.64 m/s
Part c)
By energy conservation of the rolling sphere we can say
Part d)
Now we know that
