Whiskers and beaks
are two examples of _____. electroreceptors mechanoreceptors olfactory
receptors photoreceptors
Whiskers and beaks
are two examples of olfactory receptors. An olfactory receptor is a smell
receptor that contains a protein capable of binding odor molecules that plays
the central role of smell.
Answer : The final temperature is, 
Explanation :
As we know that,
![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](https://tex.z-dn.net/?f=m_1%5Ctimes%20c_1%5Ctimes%20%28T_%7Bfinal%7D-T_1%29%3D-%5Bm_2%5Ctimes%20c_2%5Ctimes%20%28T_%7Bfinal%7D-T_2%29%5D)
.................(1)
where,
q = heat absorbed or released
= mass of water at 
= 150 g
= mass of water at 
= 100 g
= final temperature = ?
= temperature of lead = 
= temperature of water = 
= same (for water)
Now put all the given values in equation (1), we get
![150\times (T_{final}-363)=-[100\times (T_{final}-303)]](https://tex.z-dn.net/?f=150%5Ctimes%20%28T_%7Bfinal%7D-363%29%3D-%5B100%5Ctimes%20%28T_%7Bfinal%7D-303%29%5D)
Therefore, the final temperature is,
When a nucleus emits a positron, its atomic number is lowered by one but its mass number stays the same.
Inside the ground, different types of rocks and minerals are pressed together. The pressure causes the rocks to go together and form the sediments. Examples of sedimentary rocks are: sandstone, siltstone, and shale.
