Answer:
I can only answer one question. I suggest you split the questions and upload them separately.
2. Yes the capacitor will experience dielectric breakdown with a new voltage of 1.56x10^-6v.
Explanation:
Dielectric breakdown of a capacitor occurs when the capacitor loses its conductivity due to the installation of high insulating materials.
The formula for capacitance is C = ∈οΑ/d
where ∈ο = 8.85x10^-12
A = 6.35x10^-6mm^2
C = 3.23μF
d = 8.85x10^-12 x 6.35x10^-6 / 3.23x10-6
The distance between the plate d = 1.74x10^-11 m
The constant between the old and new capacitance = 5.63mF
is C1 = KC
K = C1/C = 5.63x10^-3/ 3.23x10^-6 = 1743
When the capacitor is connected to a voltage of 110v;
v = 110 / 1743 = 0.063v
the new voltage V = ED
= 8.99x10^4 x 1.74x10^-11 = 1.56x10^-6v

A body having mass 200g id moving with velocity 120m\s. What is its power
Answers
Answer:
P = 24 watts
Explanation:
Given that,
Mass, m = 200 g = 0.2 kg
Velocity of the body, v = 120 m/s
We need to find the power of the body. The formula for power is given by :
P = Fv
Here, F = W (weight) i.e. mg
So,
P = 0.2 × 120
P = 24 Watts
So, the power of the body is 24 watts.

write down an example scenario of an object that has acceleration
Answers
Answer:
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.
if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both.

b) The south magnetic pole attracts the north pole of another magnet.
c) A magnetic material that has not been made into a magnet is not attracted to either the north and south pole of a magnet.
d) The north magnet pole attracts the north magnetic pole of another magnet.
e) The south magnetic pole attracts the south magnetic pole of another magnet.
Answers
Answer: B. The south magnetic pole attracts the north pole of another magnet.
Explanation:
The correct statement below about the interaction between magnets, magnetic materials and charges is that the south magnetic pole attracts the north pole of another magnet.
We should note that a magnet typically consists of two poles which are the North Pole and the South pole. The opposite poles doesn't repel each other but attracts each other while same pole repels one another.
In this case, the North Pole will attract the South Pole while same magnetic piles repel e.g the North Pole will repel the North Pole.

What is the speed of a car traveling 100 m in 20 s?
Answers
Answer: To answer this question, we will need the following equation: SPEED = DISTANCE/TIME (A multiplication and division triangle will be shown)i) The speed of the car is calculated by doing 100 metres/ 20 seconds which gives us 5 metres per second. ii) Rearranging the equation earlier, we can make the distance the subject of the equation so that we get SPEED x TIME = DISTANCE. We worked out the speed and the time was given as 1 minute 40 seconds but we cannot plug in the numbers yet as the time has to be converted to units of seconds (because our speed is in meters per second). 1 minute 40 seconds = 60 seconds + 40 seconds = 100 secondsWe then plug in the numbers to get the distance travelled = 5 metres per second x 100 seconds = 500 metres.

A sports car moving at constant speed travels 164 m in 13.77 s. If it then brakes and comes to a stop in 3.6 s. What is its acceleration in terms of "g's", where 1.00 g = 9.80 m/s2?
Answers
Answer:
a = - 0.3376 g's
Explanation:
The sports car has a constant speed when travelling. Covered 164 m in 13.77 s. Thus, speed = 164/13.77 m/s
It brakes and now comes to a stop in 3.6 s.
Thus final velocity = 0 m/s
Formula for acceleration is;
a = (v - u)/t
a = (0 - (164/13.77))/3.6
a = -3.308 m/s²
In terms of g's", where 1.00 g = 9.80 m/s², we have;
a = -3.308/9.8 g's
a = - 0.3376 g's
A vibration platform oscillates up and down with a fixed amplitude of 9.7 cm and a controlled frequency that can be varied. If a small rock of unknown mass is placed on the platform, at what frequency will the rock just begin to leave the surface so that it starts to clatter?
Answers
Answer:
1.6 Hz
Explanation:
In simple harmonic motion, acceleration is given by the formula;
a = Aω²
Where;
A is amplitude
ω is angular velocity.
We are given A = 9.7 cm = 0.097 m
We know that acceleration due to gravity is 9.8 m/s².
Thus;
9.8 = 0.097ω²
ω² = 9.8/0.097
ω = √101.031
ω = 10.05 rad/s
Formula for frequency is;
f = ω/2π
Thus;
f = 10.05/2π
f = 1.6 Hz

You have been accepted into a boat building competition. You get to pick between two boat plans. Boat A’s plans has the dimensions of 45m wide and 126m long and exerts 2300Pa of pressure. Boat B’s plans has the dimensions of 6m wide and 115m long and exerts 2700Pa of pressure. In order for the boat to float, the force applied to the water must not exceed 2.0 X 10 6 N. Would you pick Plan A or Plan B?
Answers
Answer:
the force B is less than the maximum force consequently Boat B floats
Explanation:
To solve this exercise let's use the pressure defined
P = [tex]\frac{F}{A}[/tex]
F = P A
let's start for boat A
let's search the area
A = l a
A₁ = 45 126
A₁ = 5670 m²
the force applied by this ship is
F₁ = 2300 5670
F₁ = 1.3 10⁷ N
now we do the calculation for ship B
A₂ = 6 115
A₂ = 690 m²
F₂ = P₂ A₂
F₂ = 2700 690
F₂ = 1.8 10⁶ N
indicate that the force should not be greater than F₀ = 2.0 10⁶ N, let's look for the relationship with each one
[tex]\frac{F_1}{F_0}[/tex] = 1.3 10⁷/2 10⁶
F₁ = 6.5 F₀
This force is greater than the one that can resist therefore the ship and sinks
[tex]\frac{F_2}{F_o}[/tex] = 1.8 /2
F₂ = 0.9 F₀
therefore this force is less than the maximum force consequently Boat B floats

g An electromagnetic wave is traveling on a transmission line. Its voltage is given by v(x, t) = 10 Exp[−γx] cos(15x − 109 t) where x is the distance (in meters) from the generator, and t is in seconds. (a) What is the frequency, wavelength and phase veolicty of the electromagnetic wave. (b) at x = 3 m, the wave amplitude is measured to be 4V . Determine γ
Answers
Answer:
a)
f = 1.59*10⁸ Hz.
λ = 0.42 m
vp = 0.67*10⁸ m/s = 0.22 c
b)
γ = 0.31 1/m
Explanation:
a)
In a transmission line, voltage varies sinusoidally with the distance and time.We can express mathematically this relationship in a cosine form as follows:V (x,t) = A cos (kx-ωt + φ₀) (1)where A = amplitude of the wave (Volts)k = number of wave = 2*π/λ (being λ the wavelength of the wave)ω = angular frequency = 2*π*f (being f the frequency of the wave)φ₀ = phase of the wave.In our case, the expression for the voltage is as follows:v (x,t) = 10 V Exp [-γx] cos (15x-10⁹ t) (2)From (1) and (2) we find the following equalities:k = 15 = 2*π/λ (3)Solving for λ:[tex]\lambda = \frac{2*\pi }{k} =\frac{2*\pi }{(15)1/m} = 0.42 m (4)[/tex]
ω = 2*π*f = 10⁹ rad/sec (5)Solving for f:[tex]f = \frac{\omega }{2*\pi } =\frac{10e9rad/sec }{(2*\pi rad} = 1.59*e8 (6)[/tex]
The phase velocity of the wave is just the product of the wavelength times the frequency, as follows:[tex]v_{phase} =\lambda * f = 0.42m * 1.59e8 1/sec = 0.67e8 m/s (7)[/tex]
b)
We can express the amplitude at any time as follows:[tex]V = 10 V *e^{-\gamma*x} (8)[/tex]
If we know that V= 4 V at x=3m, (8) becomes:[tex]10 V *e^{-\gamma*3m} = 4 V (9)[/tex]
Taking ln on both sides, we can solve for γ as follows:[tex]-\gamma*3m* ln e = -\gamma*3m = ln (\frac{4V}{10V}) = ln 0.4\\\gamma = -\frac{ln 0.4}{3m} = 0.31 (1/m) (10)[/tex]
γ = 0.31 1/m

In the following problems, assume the following parameters:
Mass of the bottom steel disc: 1.468 kg.
Mass of the upper steel disc: 1.479 kg.
Mass of the upper aluminum disc: 0.461 kg.
Radius of each disc: 63.3 mm.
Radius of the take-up spool: r= 1.25 cm.
Mass of the falling weight: 25 grams.1.

a. The moment of inertia of the lower, steel disc.
b. The moment of inertia of the upper, steel disc.
c. The moment of inertia of the upper, aluminum disc.
d. The combined moment of inertia of the two steel discs.

3. Suppose that the counter is reading 400 counts per second at some moment. What is the value of Ïat that moment?
Answers
Answer:
1) a) I₁ = 0.2941 kg m², b) I₂ = 0.2963 kg m², c) I_{total} = 0.5904 kg m²
3) α = 6.31 10⁶ rad / s²
Explanation:
1) The moment of inertia for bodies with high symmetry is tabulated, for a divo with an axis passing through its center is
I = ½ m r²
a) moment of inertia of the upper disk
I₁ = ½ m₁ r₁²
I₁ = ½ 1,468 0.633²
I₁ = 0.2941 kg m²
b) upper aluminum disc moment of inertia
I₂ = ½ m₂ r₂²
I₂ = ½ 1.479 0.633²
I₂ = 0.2963 kg m²
c) the moment of inertia is an additive scalar quantity therefore
I_{total} = I₁ + I₂
I_{total} = 0.2941 + 0.2963
I_{total} = 0.5904 kg m²
3) ask the value of the angular acceleration, that is, the second derivative of the angle with respect to time squared
indicate the angular velocity of the system w = 400 rev / s
Let's reduce the SI system
w = 400 rev / s (2π rad / rev) = 2513.27 rad / s
as the system is rotating we can calculate the centripetal acceleration
a = w² R
a = 2513.27² 0.633
a = 3.998 10⁶ m / s²
the linear and angular variable are related
a = α r
α = a / r
α = 3.998 10⁶ / 0.633
α = 6.31 10⁶ rad / s²

What is a scientific finding?The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries). It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation.
It involves formulating hypotheses, via induction, based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.
Although procedures vary from one field of inquiry to another, the underlying process is frequently the same from one field to another. The process in the scientific method involves making conjectures (hypothetical explanations), deriving predictions from the hypotheses as logical consequences, and then carrying out experiments or empirical observations based on those predictions.
