Answer:

D

Explanation:

Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.

Answer:

Graph C

Explanation:

With the same force and more mass, the position in time will still be parabolic

i.e.  x = ½at², but the rate of acceleration will be lower so the position curve will be broader.

Answer:

the period of the physical pendulum is 0.498 s

Explanation:

Given the data in the question;

[tex]T_{simple[/tex] = 0.61 s

we know that, the relationship between T and angular frequency is;

T = 2π/ω ---------- let this be equation 1

Also, the angular frequency of physical pendulum is;

ω = √(mgL / [tex]I[/tex] ) ------ let this equation 2

where m is mass of pendulum, L is distance between axis of rotation and the center of gravity of rod and [tex]I[/tex]  is moment of inertia of rod.

Now, moment of inertia of thin uniform rod D is;

[tex]I[/tex] = [tex]\frac{1}{3}[/tex]mD²

since we were not given the length of the rod but rather the period of the simple pendulum, lets combine this three equations.

we substitute equation 2 into equation 1

we have;

T = 2π/ω OR T = 2π/√(mgL/[tex]I[/tex]) OR T = 2π√([tex]I[/tex]/mgL)

so we can use [tex]I[/tex] = [tex]\frac{1}{3}[/tex]mD² for moment of inertia of the rod

Since center of gravity of the uniform rod lies at the center of rod

so that L =  [tex]\frac{1}{2}[/tex]D.

now, substituting these equations, the period becomes;

T = 2π/√([tex]I[/tex]/mgL) OR T = [tex]2\pi \sqrt{\frac{\frac{1}{3}mD^2 }{mg(\frac{1}{2})D } }[/tex] OR T = 2π√(2D/3g )  ----- equation 3

length of rod D is still unknown, so from equation 1 and 2 ( period of pendulum ),

we have;

ω[tex]_{simple[/tex] = 2π/[tex]T_{simple[/tex] OR  ω[tex]_{simple[/tex] = √(g/D) OR  ω[tex]_{simple[/tex] = 2π√( D/g )  

so we simple solve for D/g and insert into equation 3

so we have;

T = √(2/3) × [tex]T_{simple[/tex]

we substitute in value of [tex]T_{simple[/tex]

T = √(2/3) × 0.61 s

T = 0.498 s

Therefore, the period of the physical pendulum is 0.498 s

Answer:

isobaric

Explanation:

According to the attached figure, the process would be isobaric as the gas would be expanded at the time when it maintains the constant pressure

The ideal gas law derives

PV = nRT

As the flame is there at the bottom side so atoms or molecules of gas would get heat up slowly also their temperature would be increased. Thus in the case when piston would not be permitted to move so the pressure would rise having maintaining the constant volume and after this the process could be isochronic but in the given case, the piston would be permitted to move slowly upward so that there is a rise in the volume. However, the gas particles would be adjust themselves in order to maintain constant pressure so the given process represent isobaric  

Answer:

[tex]22.84\ \text{N}[/tex]

Explanation:

[tex]\rho[/tex] = Density = [tex]7800\ \text{kg/m}^3[/tex]

h = Length of rod = 95 cm

d = Diameter of rod = 2 cm

r = Radius = [tex]\dfrac{d}{2}=1\ \text{cm}[/tex]

g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

V = Volume of rod = [tex]\pi r^2h[/tex]

Mass is given by

[tex]m=V\rho[/tex]

Weight is given by

[tex]w=mg=V\rho g\\\Rightarrow w=\pi r^2h\rho g\\\Rightarrow w=\pi\times (1\times 10^{-2})^2\times (95\times 10^{-2})\times 7800\times 9.81\\\Rightarrow w=22.84\ \text{N}[/tex]

The weight of the rod is [tex]22.84\ \text{N}[/tex].

Explanation:

Sleep Apnea is when someone who snores and stops breathing while sleeping

Someone who snorts and stop breathing during sleep may be suffering from Sleep Apnea. Hence, option (c) is correct.

Breathing repeatedly stops and begins while you sleep, which is a frequent symptom of sleep apnea. Your body may not receive enough oxygen as a result.

There are two different forms of sleep apnea.

Answer:

450 since in series we add the resistance

Answer:

Explanation:

There are countless household appliances in every single house. One appliance with a low power rating would be a ceiling fan. On average ceiling fans consume roughly 60w and are found in the majority of houses. On the other side of the spectrum, we have a high power-rating appliance such as a microwave. Microwaves use anywhere between 1000w to 1800w of power in order to function correctly. This is very large power consumption and one of the highest power ratings found for appliances in a household.

Answer:

The limitations of sending information using electromagnetic waves is that when the electromagnetic waves move outward in all directions, wave transmitters need to be focused to transmit their signals to a single specified location.

Answer:

D

Explanation:

when we placed in the container of real depth assuming = d

if the container filled with liquid A then its apparent depth d' = 7cm

so the refractive index nA = real depth / apparent depth

                                       = d/7cm = 0.1428d

if the container filled with liquid B then its apparent depth d' = 6cm

so the refractive index nB = real depth / apparent depth

                                       = d/6cm = 0.166d

if the container filled with liquid C then its apparent depth d' = 5cm

so the refractive index nC = real depth / apparent depth

                                       = d/5cm = 0.2d

Since the refractive index is inversely proportional to the apparent depth

then the refractive indices are nC > nB > nA

Answer:

t = 0.4 seconds

Explanation:

Given that,

Mass of the object, m = 2 kg

Initial speed of the object, u = 3 m/s

Finally, it stops, v = 0

Constant force applied to the object, F = 15 N

We know that,

Force, F = ma

[tex]F=\dfrac{m(v-u)}{t}\\\\t=\dfrac{m(v-u)}{F}\\\\t=\dfrac{2\times (0-3)}{15}\\\\=0.4\ s[/tex]

So, it will take 0.4 seconds to stop the mass.

It needs fuse of size 3A to be operated

Answer: 10 A

Explanation: The 3a and 5 a will blow immediately which would not allow you to use the coffee machine

The 13 a is too high and might lead to damage to the coffee machine or a fire being started

10 A is perfect because its low enough that if their was a power surge it would be blown without damaging anything else and it is high enough to let the coffee machine work without any trouble

Answer:

An unconformity shows where some rock layers have been lost because of erosion. To date rock layers, geologists first give a relative age to a layer of rock at one location and then give the same age to matching layers at other locations. Certain fossils, called index fossils, help geologists match rock layers.

Answer:

d = 0.343 m

Explanation:

Given that,

The speed of a longitudinal wave, v = 343 m/s

Your ear is capable of differentiating sounds that arrive at the ear just 1.00 milliseconds apart.

We need to find the minimum distance between two speakers that produce sounds that arrive at noticeably different times.

Let the distance be d. So,

[tex]d=v\times t\\\\=343\times 10^{-3}\\\\=0.343\ m[/tex]

So, the required distance is equal to 0.343 m.

Answer:

T = 4 N

Explanation:

Given that,

Weight of a car, W = 80 N

We know that,

Weight = mg

80 = 10m

m = 8 kg

If the acceleration of the car is 0.5 m/s², then force becomes,

F = 8 × 0.5

F= 4 N

So, the required tension force is 4 N.
