Answer:

The difference between rotations and revolutions is , when an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.

Explanation:

While rotation means spinning around its own axis, revolution means to move around another object. Taking the example of the Earth, which rotates 366 times to complete one revolution around the Sun.

Suppose high tide is at midnight, the water level at midnight is 3 m, and the water level at low tide is 0.5 m. Assuming the nex

aev [14]

We have that the time, to the nearest minute, when the water level is at 1.125 m for the second time after midnight is

$t=10.0hours$

From the Question we are told that

Maximum height $h_{max}=3m$

Minimum height $H_{min}=0.5m$

Time for next high tide will occur $T=12 hours =>720 min$

Generally Average Height

$h_{avg}=\frac{3+0.5}{2}\\\\h_{avg}=1.75$

Therefore determine Amplitude to be

$A=h_{max}=j_{avg}\\\\A=3-1.75\\\\A=1.25$

Generally, the equation for Time is mathematically given by

At t=0

$h(x)=Acos(Bx)+h_{avg}$

Where

$B=\frac{2\pi}{P}\\\\B=\frac{2\pi}{720}\\\\B=8.73*10^{-3}$

Therefore

$h(t)=Acos8.73*10^{-3}(t)+h_{avg}$

Hence the Time at $T=1.125$ is

$1.125(t)=1.25cos(8.73*10^{-3})(t)+1.75$

$-0.1249t=1.75$

$t=10.0hours$

A star may form a black hole once it cannot ?

IceJOKER [234]

A star may form a black hole once is true. After the marked supernova explosion, the star shrinks because it sheds away the gaseous layers of the star. And especially if the star is large, it will form into a black hole.

A horizontal pipe narrows from a radius of 0.250 m to 0.1000 m. If the speed of the water in the pipe is 1.00 m/s in the larger-

umka21 [38]

Answer:

6.25 m/s

196 kg/s

Explanation:

The areas of the pipe from big to small:

$A = \pi R^2 = \pi*0.25^2 = 0.196 m^2$

$a = \pi r^2 = \pi*0.1^2=0.0314m^2$

As the product of speed and cross-section area is constant, the speed in the smaller pipe would be

$AV = av$

$v = \frac{AV}{a} = \frac{0.196 * 1}{0.0314} = 6.25 m/s$

The mass flow rate would be:

$\dot{m} = \ro AV = 1000 * 0.196 * 1 = 196 kg/s$
