Answer:
The speed will be "3.4×10⁴ m/s²".
Explanation:
The given values are:
Angular speed,
w = 7200 rpm
i.e.,
=
=
Speed from the center,
r = 6.0 cm
As we know,
⇒ Linear speed,
On putting the estimated values, we get
Now,
Acceleration on disk will be:
⇒
The answer would be: <span>b. interactions between the atmosphere and geosphere during a drought
The experiment is clearly demonstrating what happens in drought. The soil that is put into direct sunlight without getting any water. The heat from the sunlight will be absorbed by the soil, makes the water content of the soil evaporates into the air. Since you don't give any water, the soil will be dry and start to crack.
The soil should represent the geosphere. The air represents the atmosphere.

Explanation:
It is known that general formula to calculate the volume of a cone is as follows.
Volume of the cone =
and here, r =
So, V =
On putting the given values into the above formula we will calculate the value f h as follows.
V =
=
=
Now, we will differentiate w.r.t t as follows.
=
It is given that water here flows at a rate of 1.5 and h = 1.1 m.
1.5 =
1.5 =
= 0.888
= 0.9 m/min (approx)
Thus, we can conclude that the water level is rising at a rate of 0.9 m/min.
