Answer:
0.59 cm
Explanation:
height of cup (h) = 10 cm
radius of cup (r) = 10 cm
rate of change of water level (V') = 16π/3
rate of change of height (h) = 3 cm
the ratio of the height to radius (h:r) = 10:10
h/r = 10/10
h/r = 1
r=h
formula for volume of a volume (v) = .πh
substituting r=h into the formula above we have
v = .π. h = .π
differentiating the above we have
v' = 3(π)h' = π.h'
rearranging the above we have
h' = v' / (π)
where
- v' = rate of change of water level
- h' = rate of change of water level
- h = water level
h' = ((16 x π) / 3) ÷ ( π x )
h' = ((16 x 3.142) / 3) ÷ ( 3.142 x )
h' = 16.76 / 28.28
h' = 0.59 cm
Answer:
When it comes to serving, the court is divided into six zones. Right back is zone one, right front is zone two, middle front is zone three, left front is zone four, left back is zone five and middle back is zone six.
Explanation:
The position of John at time of 4.35 s is -1.13 m
From the given chart;
- at time, t = 0, the initial velocity, u = - 2 m/s
- at time, t = 5 s, the final velocity, v = 2 m/s
The average acceleration is calculated as follows;
<h3>
</h3>
The position of John at time, t = 4.35 s is calculated as follows;
Thus, the position of John at time of 4.35 s is -1.13 m

If you wanted the laser to refract less as it exits the prism, you should increase the wavelength of the light.
<h3>What is
refraction?</h3>
Refraction can be defined as a phenomenon which describes a change (bend) in the path taken by light when it's at surfaces between different transparent materials.
According to the model of light wave, the refraction of light is inversely proportional to its wave. Thus, you should increase the wavelength of light, if you want the laser to refract less as it exits the prism.

The lever is a movable bar that pivots on a fulcrum attached to or positioned on or across a fixed point. The lever operates by applying forces at different distances from the fulcrum, or pivot.
A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever.
The mechanical advantage of the lever is increased by moving the fulcrum closer to the load i.e., by shifting the fulcrum towards the right. Moving the fulcrum away from the load has mechanical disadvantage as the distance between the load and the fulcrum increases, the input force becomes greater than the output force.
