Answer:
The value is 
Explanation:
From the question we are told that
The the peak wavelength is 
Generally according to the Wien's displacement law
Here T is the approximate surface temperature of this star in K so
=> 
Converting to Fahrenheit ,
![T = [400 - 273.15 ] * \frac{9}{5} + 32](https://tex.z-dn.net/?f=T%20%3D%20%5B400%20-%20273.15%20%5D%20%2A%20%5Cfrac%7B9%7D%7B5%7D%20%2B%2032)
=>
Answer:
<em>C. It is made from three layers of semiconductors.</em>
<em></em>
Explanation:
<em>Bipolar transistors (pnp and npn) are usually made from a sandwich of three semiconductors layers</em>. The main charge carriers are holes and electrons. An npn transistor has two semiconductor junctions that share a thin middle positively enhanced region (the material is enhanced with impurities rich in holes which are the positive charge carriers), and a pnp transistor has two semiconductor junctions that share a thin middle negatively enhanced region (material is enhanced with impurities rich in electrons, the negative charge carriers).
Answer:
Explanation:
Given
initial speed of Launch
=53.7 m/s
Range of Projectile =Maximum height of Projectile
Range is given by R
Maximum height is given by 
![\frac{u^2\sin \theta }{g}\cdot \left [ 2\cos \theta -\frac{1}{2}\right ]=0](https://tex.z-dn.net/?f=%5Cfrac%7Bu%5E2%5Csin%20%5Ctheta%20%7D%7Bg%7D%5Ccdot%20%5Cleft%20%5B%202%5Ccos%20%5Ctheta%20-%5Cfrac%7B1%7D%7B2%7D%5Cright%20%5D%3D0)
as u cannot be zero therefore
Answer:
Explanation:
If the mass of the object is 7000 grams then you would need to divide 7000 by 1000 to get your answer which would be 7 kilograms
