The speed of the ball is 101miles/hr.
A mile is a unit of length that is exactly 1,609.344 metres long. Similarly, 5,280 feet or 1,760 yards make up one mile. The mile is an imperial and common US measurement of distance.
We just have to deal with unit conversions.
One mile is 5280 feet, or 1 ft = 0.000189
The speed of the ball in miles per hour is
![\frac{148ft}{1sec} . \frac{1mile}{5280ft} .\frac{60s}{1min} .\frac{60min}{1hr}](https://tex.z-dn.net/?f=%5Cfrac%7B148ft%7D%7B1sec%7D%20.%20%5Cfrac%7B1mile%7D%7B5280ft%7D%20.%5Cfrac%7B60s%7D%7B1min%7D%20.%5Cfrac%7B60min%7D%7B1hr%7D)
So, the speed of the ball in miles per hour is 101miles/hr.

Because the Earth<span> is a sphere, the surface gets much more intense </span>sunlight<span>, hence heat, at </span>the equator<span>than at the poles.</span>
Answer:51.44 units
Explanation:
Given
x component of vector is ![-27.3\hat{i}](https://tex.z-dn.net/?f=-27.3%5Chat%7Bi%7D)
y component of vector is ![43.6\hat{j}](https://tex.z-dn.net/?f=43.6%5Chat%7Bj%7D)
so position vector is
![r=-27.3\hat{i}+43.6\hat{j}](https://tex.z-dn.net/?f=r%3D-27.3%5Chat%7Bi%7D%2B43.6%5Chat%7Bj%7D)
Magnitude of vector is
![|r|=\sqrt{27.3^2+43.6^2}](https://tex.z-dn.net/?f=%7Cr%7C%3D%5Csqrt%7B27.3%5E2%2B43.6%5E2%7D)
![|r|=\sqrt{2646.25}](https://tex.z-dn.net/?f=%7Cr%7C%3D%5Csqrt%7B2646.25%7D)
|r|=51.44 units
Direction
![tan\theta =\frac{43.6}{-27.3}=-1.597](https://tex.z-dn.net/?f=tan%5Ctheta%20%3D%5Cfrac%7B43.6%7D%7B-27.3%7D%3D-1.597)
vector is in 2nd quadrant thus
![180-\theta =57.94](https://tex.z-dn.net/?f=180-%5Ctheta%20%3D57.94)
![\theta =122.06^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D122.06%5E%7B%5Ccirc%7D)
Pascal's law of fluid transfer states that when there is an increase in fluid pressure, the rest of the extrinsic variables also increases. For example, in a flow of liquid in an orifice, there is a contraction of diameter in the orifice part. The fluid that will go in there increases in pressure and thereby an increase in velocity as well.
