False because the Ionsophere lies between the Mesosphere and the Theromsphere. If can can you give me brainliest :o ?
Answer:
A hypothesis is a basically a theory proposed to a subject or refrence to an act with limited evidences.
Answer:
light waves can be converted to electricity through <em>a solar cell</em>
Explanation:
The hawk’s centripetal acceleration is 2.23 m/s²
The magnitude of the acceleration under new conditions is 2.316 m/s²
radius of the horizontal arc = 10.3 m
the initial constant speed = 4.8 m/s
we know that the centripetal acceleration is given by
= ![\frac{v^{2} }{r}](https://tex.z-dn.net/?f=%5Cfrac%7Bv%5E%7B2%7D%20%7D%7Br%7D)
= 23.04/10.3
= 2.23 m/s²
It continues to fly but now with some tangential acceleration
= 0.63 m/s²
therefore the net value of acceleration is given by the resultant of the centripetal acceleration and the tangential acceleration
so
= ![\sqrt{a_{c} ^{2} +a_{t} ^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7Ba_%7Bc%7D%20%5E%7B2%7D%20%2Ba_%7Bt%7D%20%5E%7B2%7D%20%20%20%7D)
= ![\sqrt{4.97 + 0.396}](https://tex.z-dn.net/?f=%5Csqrt%7B4.97%20%2B%200.396%7D)
= 2.316 m/s²
So the magnitude of net acceleration will become 2.316 m/s².

Answer:
![Q = 4.63 \times 10^6 J](https://tex.z-dn.net/?f=Q%20%3D%204.63%20%5Ctimes%2010%5E6%20J)
Explanation:
As we know that melting point of silver is
T = 961.8 degree C
Latent heat of fusion of silver is given as
L = 111 kJ/kg
specific heat capacity of silver is given as
![s = 240 J/kg C](https://tex.z-dn.net/?f=s%20%3D%20240%20J%2Fkg%20C)
now we will have
![Q = ms\Delta T + mL](https://tex.z-dn.net/?f=Q%20%3D%20ms%5CDelta%20T%20%2B%20mL)
![\Delta T = 961.8 - 20](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20961.8%20-%2020%20)
![\Delta T = 941.8 degree C](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%20941.8%20degree%20C)
now from above equation
![Q = (13.74)(240)(941.8) + (13.74)(111 \times 10^3)](https://tex.z-dn.net/?f=Q%20%3D%20%2813.74%29%28240%29%28941.8%29%20%2B%20%2813.74%29%28111%20%5Ctimes%2010%5E3%29)
![Q = 3.1 \times 10^6 + 1.53 \times 10^6](https://tex.z-dn.net/?f=Q%20%3D%203.1%20%5Ctimes%2010%5E6%20%2B%201.53%20%5Ctimes%2010%5E6)
![Q = 4.63 \times 10^6 J](https://tex.z-dn.net/?f=Q%20%3D%204.63%20%5Ctimes%2010%5E6%20J)
