A4.0 μF capacitor is connected in series with a 2.0 MΩ resistor, and this combination is connected across an ideal 44.0 V DC battery. Initially the charge on the capacitor is zero. What is the current in the circuit when the capacitor has reached 80 % of its maximum voltage?
Answer:
i = 17.6 10⁻⁶ A
Explanation:
The charge of a capacitor in a series circuit is
i = [tex]\frac{v_o}{R}[/tex] [tex]e^{ - \frac{t}{RC} }[/tex] (1)
R i = V₀ e^{ - \frac{t}{RC} }
[tex]\frac{V}{V_o}[/tex] = e^{ - \frac{t}{RC} }
they tell us that the voltage is 80% bone
[tex]\frac{V}{V_o}[/tex] = 0.80
we substitute
0.80 = e^{ - \frac{t}{RC} }
ln 0.80 = [tex]- \frac{t}{RC}[/tex]
t = - RC ln 0.80
in the problem they give the value of R = 2.0 10⁶ Ω and C = 4.0 10⁻⁶ F
t = - 2 10⁶ 4 10⁻⁶ ln 0.8
t = 1,785 s
we substitute in equation 1
i = [tex]\frac{44.0}{2 \ 10^6}[/tex] [tex]e^{- \frac{1.785}{2 \ 4 } }[/tex]
i = 22 10⁻⁶ [tex]e^{-0.2231}[/tex]
i = 17.6 10⁻⁶ A

A lamp is on a dimmer switch. As you turn the switch from the lowest setting to the highest setting, which statement would best describe what happens? A) The light bulb consumes less electricity, burns dimmer and uses more power . B) The light bulb consumes more electricity, burns brighter and uses more power ) The light bulb consumes less electricity, burns brighter and uses more power. D) The light bulb consumes more electricity, burns brighter and uses less power.
As turn the switch from the lowest setting to the highest setting, the light bulb consumes more electricity, burns brighter and uses more power.
Rate of power consumption
The rate of power consumption is proportional to current flowing in a circuit and time of current flow.
P = I²Rt

what are solar winds made of?
A. charged particles
B. nitrogen gas
C. oxygen gas
D. plasma
Answer:
Charged particles
Explanation:
It's correct
Answer:
Charged particles
Explanation:
The solar wind is a stream of energetic (charged) particles that the Sun ejects. These include hydrogen's electrons and protons, as well as atomic nuclei like helium, which are known as alpha particles. There are also evidence of 'heavy ions' and carbon, nitrogen, oxygen, neon, and magnesium atomic nuclei.

Bees can see into the ultraviolet region of the electromagnetic spectrum. Compared with humans, bees can sense electromagnetic waves that have a lower frequency and a shorter wavelength. a higher frequency and a longer wavelength. a lower frequency and a longer wavelength. a higher frequency and a shorter wavelength.
Answer:
a higher frequency and a shorter wavelength.
Explanation:
The correct answer would be a higher frequency and a shorter wavelength.
The visible region of the electromagnetic spectrum lies between 400 and 750 nm while the ultraviolet region lies between 300 and 400 nm. Hence, it means that bees are able to see at a shorter wavelength compared to humans.
There is an inverse relationship between the wavelength and frequency of a wave. the longer the wavelength of a wave, the shorter the frequency, and the shorter the wavelength, the higher the frequency. The means that bees are not just able to see at a shorter wavelength but at a higher frequency compared to humans.

A boy of mass 50 kg walks up a staircase of 10 steps each 15 cm high. Calculate the work done.
Answer:
735 J
Explanation:
Total height reached(displaced)=10x15 cm
= 10 x 15/100 m
= 1.5 m
Workdone = F.S (force x displacement)
Here, the boy is traveling against the gravitation force(=mg) , and traveled a height of 1.5m
Hence,
Workdone = 50 x 9.8 x 1.5 J
= 735 J
Answer:
750J
Explanation:
Solution;
M=50kg, g=10m/s
Distance=15×10÷100
=1.5m
W=M×g×h
=50×10×1.5
=750J

Which model shows 4 electrons in the outer shell of the atom?
A. 1
B. 3
C. 2
D. 4
Model 4 shows 4 electrons in the outer shell of the atom. Option D is correct.
What is an atom?The atom consists of matter that may be split without releasing electrical charges.
It's also the smallest unit of matter with chemical element features. As a result, the atom is the fundamental unit of science.
In the nucleus, proton and the neutron is existing. The condition of the atom to be electrically neutral is that the number of the proton and electron should be the same.
The outermost shell, is the shell containing electrons in which limited number of the electron can be existed. When an atom's outermost electron shell is full, it is the most stable and least reactive.
Model 4 shows 4 electrons in the outer shell of the atom. It is simply obtained by calculating the no electron in the shell.
Hence, option D is correct.

Suppose A = B"Cm, where A has the dimensions LT, B has dimensions L²T-1, and C has dimensions LT2. Then the exponents n and have the values
Complete Question:
Suppose [tex]A = B^n C^m[/tex], where A has the dimensions LT, B has dimensions L²T⁻¹, and C has dimensions LT². Then the exponents n and m have the values
Answer:
The value of n = ¹/₅
The value of m = ³/₅
Explanation:
Given dimensions;
A = LT
B = L²T⁻¹
C = LT²
The values of n and m are calculated as follows;
[tex]LT = [L^2T^{-1}]^n[LT^2]^m\\\\L^1T^1 = [L^{2n}T^{-n}]\times [L^mT^{2m}]\\\\L^1 \times T^1 = [L^{(2n+m)}] \times [T^{(-n +2m)}]\\\\1 = 2n + m -----(1)\\\\1 = -n + 2m ----(2)\\\\from \ (1); \ m = 1-2n, \ \ substitute \ the \ value \ of \ m \ in\ (2)\\\\1= -n +2(1-2n)\\\\1 = -n + 2-4n\\\\1-2 = -5n\\\\-1 = -5n\\\\1= 5n\\\\n = \frac{1}{5} \\\\m = 1 - 2n\\\\m = 1 - 2(\frac{1}{5} )\\\\m = 1- \frac{2}{5} \\\\m = \frac{3}{5}[/tex]
