Answer:
the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
Explanation:
energy of ultraviolet light = 
= 
=7.91 × 10⁻¹⁹ J
=4.94 e V
energy released by the electron = 4.94 - 4.70
= 0.24 e V
potential at the surface of sphere =
0.24 = 
Q = 0.132 × 10⁻¹¹ C
hence, the charge the photoelectric effect induce is 0.132 × 10⁻¹¹ C
I’m not sure, is there any other words you can explain it in ..?
Answer:
, 48 kg
Explanation:
The density of an object is the amount of mass contained per unit of volume.
Density is given by the equation
where
m is the mass of the object
V is its volume
In this problem, we have a wooden block of dimensions:
2 m, 0.2 m, 0.2 m
So, the volume of the block is
We also know that the density of the block is
Therefore, the mass of the block is
Answer:
Tbh it's hard to find out what the blank line is, but I did my best
Explanation:
Wires provide a path through which current can flow from one end of a battery to the other. Wires are made from materials that carry, or conduct, electrons more easily than other materials. Materials that conduct electrons easily are called conductors. Copper and aluminum are good conductors.
In series, you just add them: R1 + R2 + R3 = Total R
