Answer:
No number answer; don't want to pull out a calculator lol
Explanation:
Capacitors are added in parallel; opposite of resistors.
So for 9, add 10 and 2.5 then do ((1/12.5)+(1/.3))^-1.
For 10, add 0.75 and 15 first, then the rest is the same idea as 9.
Answer:
broken pieces of glass from a window can't form a shadow.
Explanation:
the reason is that shadow is formed only when light rays hits an opaque object, which doesn't let light to pass through it, but glass is a transparent object, hence light rays passes through it forming no shadow..

Answer:
W = 8.01 × 10^(-17) [J]
Explanation:
To solve this problem we need to know the electron is a subatomic particle with a negative elementary electrical charge (-1,602 × 10-19 C), The expression to calculate the work is given by:
W = q*V
where:
q = charge = 1,602 × 10^(-19) [C]
V = voltage = 500 [V]
W = work [J]
W = 1,602 × 10^(-19) * 500
W = 8.01 × 10^(-17) [J]
Answer:
the mass of the body is 0.02 kg.
Explanation:
Given;
relative density of the oil,
= 0.875
mass of the object in oil,
= 0.013 kg
mass of the object in water,
= 0.012 kg
let the mass of the object in air = ![M_a](https://tex.z-dn.net/?f=M_a)
weight of the oil, ![W_0 = M_a - 0.013](https://tex.z-dn.net/?f=W_0%20%3D%20M_a%20-%200.013)
weight of the water, ![W_w = M_a - 0.012](https://tex.z-dn.net/?f=W_w%20%3D%20M_a%20-%200.012)
The relative density of the oil is given as;
![\gamma_0 = \frac{density \ of \ oil }{density \ of \ water} = \frac{W_0}{W_w} = \frac{M_a -0.013}{M_a -0.012} \\\\0.875 = \frac{M_a -0.013}{M_a -0.012}\\\\0.875(M_a - 0.012) = M_a - 0.013\\\\0.875M_a - 0.0105 = M_a -0.013\\\\0.875M_a - M_a = 0.0105 - 0.013\\\\-0.125 M_a = -0.0025\\\\M_a = \frac{0.0025}{0.125} \\\\M_a = 0.02 \ kg](https://tex.z-dn.net/?f=%5Cgamma_0%20%3D%20%5Cfrac%7Bdensity%20%5C%20of%20%5C%20oil%20%7D%7Bdensity%20%5C%20of%20%5C%20water%7D%20%3D%20%5Cfrac%7BW_0%7D%7BW_w%7D%20%3D%20%5Cfrac%7BM_a%20-0.013%7D%7BM_a%20-0.012%7D%20%5C%5C%5C%5C0.875%20%3D%20%5Cfrac%7BM_a%20-0.013%7D%7BM_a%20-0.012%7D%5C%5C%5C%5C0.875%28M_a%20-%200.012%29%20%3D%20M_a%20-%200.013%5C%5C%5C%5C0.875M_a%20-%200.0105%20%3D%20M_a%20-0.013%5C%5C%5C%5C0.875M_a%20-%20M_a%20%3D%200.0105%20-%200.013%5C%5C%5C%5C-0.125%20M_a%20%3D%20-0.0025%5C%5C%5C%5CM_a%20%3D%20%5Cfrac%7B0.0025%7D%7B0.125%7D%20%5C%5C%5C%5CM_a%20%3D%200.02%20%5C%20kg)
Therefore, the mass of the body is 0.02 kg.
