<span>C.) A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it.
Nonmetals do not conduct energy any way and you want the metalloid to be conductive so it can provide you with energy.
</span><span>C.) intermediate conductivity and a high melting point
</span>It conducts electricity fairly well.
Hope this helps.
Answer:
A.
Explanation:
momentum depends on weight and speed
Answer:
both magnitude and direction
Explanation:
When an object moves in a circular path, its motion is called uniform circular motion. In this motion, the force acting on it is centripetal force and it is moving under centripetal acceleration. This type of force acts towards the centre of the circle.
In this type of motion, the speed remains constant while the velocity keeps on changing. The object's centripetal acceleration remains constant in magnitude as well as direction.
Hence, the correct option is (3).
Answer:
The largest allowable Io = 5.863 * 10^26 photons
Explanation:
thickness of slab = 2.8 mm
First we express the energy of each photon
wavelength = 313 nm
attached below is the detailed solution on how i arrived at the answer above
note : we use 2 in the integral because the slab is exposed to light from two different direction
