Answer:
R = 1.79*10^6 Ω
C = 2.46*10^-6 F
Explanation:
Given
emf of the source, ε = 120 V
Current passing through the resistor, I = 6.7*10^-5 A
Time constant for the circuit, τ = 4.4 s
From the information above, we can say that RC = 4.4 s
Also, on applying the loop rule, we get
ε - IR = 0
ε = IR
R = ε / I
R = 120 / 6.7*10^-5
R = 1.79*10^6 Ω
Using the first equation, we can thus solve for C
RC = 4.4 s
C = 4.4 / R
C = 4.4 / 1.79*10^6
C = 2.46*10^-6 F
C = 2.46 μF
Therefore, the resistance and capacitance of the capacitor is respectively, 1.79 MΩ and 2.46 μF

Answer:
Significant Others
Explanation:
The relationship between Solomon and his coach is termed Significant Others.
George Herbert Mead used the words "Significant Others" in sociology to imply the individuals (friends, colleagues, boss, tutors, coach, etc.) that are the most significant or important in the wellbeing of an individual or self development of that individual.
In other words, they are individuals who have an important influence or play a formative role in shaping the behaviour of another
Answer;
- Nuclear fusion
Explanation;
-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.
-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.
-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.
The flatter concave lens becomes the emergent ray moves towards being parallel two incident rays.
Explanation-
A concave lens is a lens that diverges the rays, passing through the lens, from its path thereby appearing to come from a point where image is formed these types of lenses are used by people who find trouble in seeing things that are at a distance. The flatter the lens become it moves more towards becoming a glass slab which refracts the light such that the emergent ray is parallel two incident Ray but only from another point.
