The velocity of the ball is 12.5 m/s
Explanation:
The velocity of the ball is given by the ratio between the distance covered by the ball and the time taken:
First, we calculate the distance covered. We know that the radius of the circle is
r = 0.450 m
And the length of the circumference is
The ball makes 25.0 revolutions, so a total distance of
In a time of
t = 9.37 s
So, its velocity is

The answer would be solubility
(A)
Explanation:
We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that
Since resistor Y dissipates 100 W of power, we can solve for the current as
c-undergoes the most change
Explanation:
Horizon B is the layer in a soil profile that has undergone the most change.
A section through a typical soil reveals many of the different layers.
The rock layers are divided into sections which are called horizons.
Horizon O is the organic matter
Horizon A is the top soil
Horizon B is the subsoil.
The subsoil of horizon B is the layer that undergoes the most change. It materials are constantly being leached away from this layer by chemical weathering. Some of the processes here accounts for it typical reddish brown color.
The rock layer here is rich in iron oxide and washed down minerals. It lacks significant amount of humus.
