If something is being carried by westerlies, what direction is it moving??

sergejj [24]

Winds are immigrants. They're named for where they have already been and are coming from, not for where they're going.

A Westerly wind is coming from the West. Anything caught in it is being blown toward the east.

What is the energy of a mole of photons that have a wavelength of 413 nm? (h = 6.626 × 10⁻³⁴ J • s and c = 3.00 × 10⁸ m/s)

Triss [41]

Answer:

Energy of one mole of photon will be $2.89\times 10^5J$

Explanation:

We have given wavelength of photon $\lambda =413nm=413\times 10^{-9}m$

Velocity of light is given $c=3\times 10^8m/sec$

Plank's constant $h=6.626\times 10^{-34}Js$

Energy of the photon is given by $E=\frac{hc}{\lambda }=\frac{6.626\times 10^{-34}\times 3\times 10^8}{413\times 10^{-9}}=0.048\times 10^{-17}J$

We have to find the energy of one mole of photon

One mole of photon is equal to $6.023\times 10^{23}photon$

So energy of one mole of photon will be equal to $6.023\times 10^{23}\times 0.048\times 10^{-17}=2.89\times 10^5J$

So energy of one mole of photon will be $2.89\times 10^5J$

A tertiary source is the most desirable source for a researcher to use. True or false

Kaylis [27]

The statement ‘A tertiary source is the most desirable source for a researcher to use’ is false. It should be that your source is primary because it is more reliable and is related to the research you have been working on.

A block of aluminum with a mass of 1 kg is placed in a beaker of water filled to the brim. Water overflows. The same is done in

RSB [31]

Answer:Aluminium displaces more water

Explanation:

Given

mass of aluminium block=1 kg

mass of lead block= 1 kg

Also we know density of lead $=11.34 gm/cm^3$

Density of Aluminium $=2.70 gm/cm^3$

As the density of lead is more than that of Aluminium therefore its volume is lesser than Aluminium for same mass.

Thus aluminium displaces more amount of water as compared to lead.
