Answer:
1. Frequency = speed / wavelength
here we know
speed = 343 m/s
wavelength = 0.77955 m
now frequency is given by
f = 440 Hz
2. Frequency = speed / wavelength
here we know
speed = 343 m/s
wavelength = 0.52028 m
now frequency is given by
f = 659.3 Hz
3. Frequency = speed / wavelength
here we know
speed = 343 m/s
wavelength = 0.65552 m
now frequency is given by
f = 523.25 Hz
4. Wavelength = speed / Frequency
here we know
speed = 343 m/s
Frequency = 587.33 Hz
now wavelength is given by
5. Wavelength = speed / Frequency
here we know
speed = 343 m/s
Frequency = 493.88 Hz
now wavelength is given by
6. Wavelength = speed / Frequency
here we know
speed = 343 m/s
Frequency = 698.46 Hz
now wavelength is given by
7. Frequency = speed / wavelength
here we know
speed = 343 m/s
wavelength = 0.5840 m
now frequency is given by
f = 587.3 Hz
8. Frequency = speed / wavelength
here we know
speed = 343 m/s
wavelength = 0.4375 m
now frequency is given by
f = 784 Hz
9. Wavelength = speed / Frequency
here we know
speed = 343 m/s
Frequency = 783.99 Hz
now wavelength is given by
10. Wavelength = speed / Frequency
here we know
speed = 343 m/s
Frequency = 659.26 Hz
now wavelength is given by
Answer:
The ability to do work
Explanation:
Energy can be defined as the ability to do work. We apply energy in basically everything we do in life, energy is needed to walk or move from one position to another, it is required to eat and do other basic things of life. The body system converts the food that is being consumed into energy, this energy can be switched from one form to another.
There are various forms of energy which include solar energy , wind energy, electrical energy, mechanical energy, kinetic energy, potential energy etc. This forms of energy can be converted from one form to anothe but cannot be destroyed.
The metals are the elements that more easily can lose electrons to fill their outermost shell. And among the metals the alkalyne are most likely than alkalyne earth and these are most likely than other metals.
As less electrons the metal has in its outermost shell the more likely it will lose an electron fo fill its outermost shell.
So, Li, Na, K, Rb, Cs, and Fr have one electron in their outermost shell, so they are more likely to lose an electron to fill their outermost shell than Be, Mg, Ca, Sr, Ba, Ram which have two electrons in their outermost shell.
Using the same reasoning, Be, Mg, Ca, Sr, Ba, Ra are more likely to lose an electron to fill its outermost shell than Al, Ga, In, Tl.
Al, Ga, In, Tl are more likely to lose an electron than Si, Ge, Sn, Pb.
Si, Ge, Sn, Pb are more likely to lose an electron than O, S, Se, Te, Po
O, S, Se, Te, Po are more likely to lose an electron than F, Cl, Br, I, At
F, Cl, Br, I, At (halogens) and He, Ne, Ar, Kr, Xe, Rn (noble gases) will not likely lose electrons.
The gravity of the Sun keeps the planets in their orbits rotating. The same as the Moon orbits the Earth because of the pull of earth's gravity, the earth orbits the Sun because of the pull of the Sun's gravitational pull.
Any questions please feel free to ask. Thanks
A delightful problem !
I'm pretty sure that what we need here is the speeds, not the velocities,
and that's the way I'm going to do it.
Regular speed is (distance covered) divided by (time to cover the distance) .
Angular speed is very much the same.
It's
(angle turned) divided by (time to turn the angle) .
<u>Earth's orbit around the sun</u>:
..... Once per year.
..... Roughly 360° in 365 days ..... <em>almost exactly 1° per day</em>.
Let's see what it is more accurately:
(360°) / (<span>365.25636<span> days) = 0.985609° per day.
============================================
<u>Earth's rotation on its axis</u>:
..... Once per "day".
..... Roughly 360° in 24 hours ..... <em>almost exactly 15° per hour</em>.
This one is slightly trickier to do more accurately, because a day is
not necessarily 24 hours. It depends on what you call 1 day.
-- If you say the day is the period of time between when the sun is
highest in the sky, then that averages out to 24 hours in the course
of a year.
-- If you say that the day is the period of time it takes for a star
to reach the same point in the sky tomorrow night, then that's </span></span>
23 hours, 56 minutes, 4.09 seconds .
Using this to calculate the angular speed of rotation, you get
(360°) / (23h 56m 4.09s) = 15.041° per hour
