Answer : Infrared rays have a shorter wavelength than radio waves.
Explanation :
The wavelength of Infrared rays is 700 nm – 1 mm
The wavelength of X- rays is 0.01 nm – 10 nm
The wavelength of UV rays is 10 nm – 400 nm
The wavelength of radio waves is 1 meter – 100,000 km
The wavelength of gamma rays is less than 0.01 nm
So, from the above data it is clear that the wavelength of the infrared rays have a wavelength shorter than the radio waves.
Hence, the correct option is (C) " radio waves ".
Answer:
2.3×10−1
Explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer:
(a)
= 3910 ![\frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%7D)
(b)
= 5181 ![\frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%7D)
(c)
= 2762955 m
Explanation:
Using equations of uniformly accelerated motion:
Equations:
-
![V_{f} = V_{i} + a*t](https://tex.z-dn.net/?f=V_%7Bf%7D%20%3D%20V_%7Bi%7D%20%2B%20a%2At)
-
![y_{f}=y_{i} +v_{i} + \frac{1}{2} *a*t^{2}](https://tex.z-dn.net/?f=y_%7Bf%7D%3Dy_%7Bi%7D%20%2Bv_%7Bi%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%2Aa%2At%5E%7B2%7D)
![v_{f} ^{2} =v_{i} ^{2} + 2 *a * Δy](https://tex.z-dn.net/?f=v_%7Bf%7D%20%5E%7B2%7D%20%3Dv_%7Bi%7D%20%5E%7B2%7D%20%2B%202%20%2Aa%20%2A%20%CE%94y)
(a) Using equation 1:
⇒
Because it upward from rest
![v_{f} = 85 \frac{m}{s^{2} } * 46 s](https://tex.z-dn.net/?f=v_%7Bf%7D%20%3D%2085%20%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D%20%20%2A%20%2046%20s)
![v_{f}= 3910 \frac{m}{s}](https://tex.z-dn.net/?f=v_%7Bf%7D%3D%203910%20%5Cfrac%7Bm%7D%7Bs%7D)
(b) Using equation 1:
⇒
Because is the is the initial speed in the movement before changing acceleration
![v_{f2} = 3910 \frac{m}{s} + 31 \frac{m}{s^{2} } * 41 s](https://tex.z-dn.net/?f=v_%7Bf2%7D%20%3D%203910%20%5Cfrac%7Bm%7D%7Bs%7D%20%2B%2031%20%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D%20%2A%2041%20s)
![v_{f2} = 5181 \frac{m}{s}](https://tex.z-dn.net/?f=v_%7Bf2%7D%20%3D%205181%20%5Cfrac%7Bm%7D%7Bs%7D%20)
(c) Using equation 2:
⇒
and
Because it upward from rest
![y_{f1} = \frac{1}{2} * 85\frac{m}{s^{2} } * 46s^{2}](https://tex.z-dn.net/?f=y_%7Bf1%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2085%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D%20%20%2A%2046s%5E%7B2%7D)
![y_{f1} = 89930 m](https://tex.z-dn.net/?f=y_%7Bf1%7D%20%3D%2089930%20m)
⇒
![y_{f2}= 89930 m + 3910 \frac{m}{s} + \frac{1}{2} * 31 \frac{m}{s^{2} } *41^{2}](https://tex.z-dn.net/?f=y_%7Bf2%7D%3D%2089930%20m%20%2B%203910%20%5Cfrac%7Bm%7D%7Bs%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2031%20%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%20%7D%20%2A41%5E%7B2%7D)
![y_{f2} = 119895,5 m](https://tex.z-dn.net/?f=y_%7Bf2%7D%20%3D%20119895%2C5%20m)
