Answer:
True
Explanation:
Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.
I tried, hope this helps :)

Answer:
"Emerging technologies, such as industrial robots, artificial intelligence, and machine learning, are advancing at a rapid pace. These developments can improve the speed, quality, and cost of goods and services, but they also displace large numbers of workers."
Explanation:
This means in the furture we will have many technologies doing our day to day life things.
Answer:
To check whether a chemical equation is balanced or not we usually look if elements on the product side are numerically equal to the reactant side or not.
A. Na + MgCl₂ → NaCl + Mg
<em> Reactant Product</em>
Na = 1 1
Mg = 1 1
Cl = 2 1
<u>Unb</u><u>alanced </u>
B. 2LiOH + H₂S → Li₂S + 2H₂O
<em>Reactant Product</em>
Li = 2 2
S = 1 1
O = 2 2
H = 4 4
<u>Balanced</u>
C. AgNO₃ + NaCl → NaNO₃ + AgCl
<em>Reactant Product</em>
Ag = 1 1
N = 1 1
Na = 1 1
Cl = 1 1
O = 3 3
<u>Balanced</u>
D. 3PBr₃ + 2Cl₂ → 3PCl₃ + 2Br₂
<em>Reactant Product</em>
P = 3 3
Br = 9 4
Cl = 4 9
<u>Unbalanced</u>
Therefore, equations B and C are balanced chemical equations.
Explanation:
Fnet = 12.0N - 5.0N = 7.0N
a = Fnet/m = 7.0N/6.5kg = 1.07m/s².
Answer:
Polarizing angle,
Given:
Critical angle,
Solution:
Now, in Total Internal Reflection (TIR), the critical angle for cubic zirconia is given by:
(1)
where
= refractive index of zirconia
From eqn (1):
Now, the angle of polarization is given by:
tan
Therefore,
