Tides are a result of <u>"the gravitational attraction of the Sun and Moon".</u>

An especially high tide (Spring tide) happens when the sun and moon are in line and both pull in a similar way.

Tides may appear to be straightforward at first glance, yet the intricate details of tides jumbled extraordinary logical masterminds for a considerable length of time they even driven Galileo astray into a bunk theory.

Today individuals realize that the gravitational pulls between the earth, moon and sun manage the tides. The moon, however, impacts tides the most.

The moon's gravitational pull on the earth is solid enough to pull the seas into bulge. On the off chance that no different powers were impacting everything, shores would encounter one high tide a day as the earth pivoted on its hub and coasts kept running into the seas' bulge confronting the moon.

On land, coal is transported primarily by train. A typical large coal train may be about 1.5 km long and may consist of 120 cars

WINSTONCH [101]

Answer:

equivalent power = 6.60 × $10^{12}$ W

Explanation:

given data

coal train length = 1.5 km = 1500 m

contain = 120 cars

holding= 110 tonnes of coal each

train traveling speed = 100 km/h = 27.78 m/s

to find out

equivalent power in watts

solution

we take here energy produce by coal is 27 × $10^{6}$ J/kg

and here total coal = 120 × 110 × 10³ kg

sop here energy produce by total coal is

energy produce by total coal = 27 × $10^{6}$ × 120 × 110 × 10³

and time required to cross that distance is

time = $\frac{distance}{speed}$

time = $\frac{1500}{27.78}$

time = 53.99 sec

so here equivalent power will be

equivalent power = $\frac{energy}{time}$

equivalent power = $\frac{27*10^6*120*110*10^3}{53.99}$

equivalent power = 6.60 × $10^{12}$ W

In a cyclotron, the orbital radius of protons with energy 300 keV is 16.0 cm . You are redesigning the cyclotron to be used inst

dem82 [27]

Answer:

$r_\alpha=16cm$

Explanation:

The radius of the circumference described by a particle in a cyclotron is given by:

$r=\frac{mv}{qB}(1)$

m is the particle's mass, v is the speed of the particle, q is the particle's charge and B is the magnitude of the magnetic field.

Kinetic energy is defined as:

$K=\frac{mv^2}{2}=\frac{m^2v^2}{2m}\\$

Solving this for mv:

$mv=\sqrt{2mK}(2)$

Replacing (2) in (1):

$r=\frac{\sqrt{2mK}}{qB}$

For protons, we have:

$r_p=\frac{\sqrt{2m_pK}}{eB}(3)$

For alpha particles, we have:

$r_\alpha=\frac{\sqrt{2m_\alpha K}}{(2e)B}(4)$

Dividing (4) in (3):

$\frac{r_\alpha}{r_p}=\frac{\frac{\sqrt{2m_\alpha K}}{(2e)B}}{\frac{\sqrt{2m_p K}}{(e)B}}\\r_\alpha=\frac{r_p}{2}\sqrt{\frac{m_\alpha}{m_p}}\\r_\alpha=\frac{16cm}{2}\sqrt{\frac{6.64*10^{-27}kg}{1.67*10^{-27}kg}}\\r_\alpha=\frac{16cm}{2}(\sqrt{3.98})\\\\r_\alpha=\frac{16cm}{2}(2)\\r_\alpha=16cm$

Two linear polarizing filters are placed one behind the other, so that their transmission directions are parallel to one another

ale4655 [162]

Answer:

0.5I0

Explanation:

Because once ligh passes though any polarizer 50% of it is gone. The second polarizer is also oriented in the same direction so it passes through with no effect.
