Three point charges are arranged at the corners of a square of side L as shown in Fig. What is the potential at the fourth corner (point A), taking V=0 at a great distance?

Answer:

[tex]\frac{T_2}{T_1} = 1[/tex]

Explanation:

The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:

[tex]v = \sqrt{\frac{3RT}{M} }[/tex]

where,

v = root mean square velocity of molecules:

R = Universal Gas Constant

T = Equilibrium Temperature

M = Molecular Mass of the Gas

Therefore,

For T = T₁ :

[tex]v = \sqrt{\frac{3RT_1}{M} }[/tex]

For T = T₂ :

[tex]v = \sqrt{\frac{3RT_2}{M} }[/tex]

Since both speeds are given to be equal. Therefore, comparing both equations, we get:

[tex]\sqrt{\frac{3RT_1}{M} }=\sqrt{\frac{3RT_2}{M} }\\\\\frac{T_2}{T_1} = 1[/tex]

Explanation:

Answer:

5.49×10¯⁴ m²

Explanation:

From the question given above, the following data were obtained:

Distance (d) = 2.22×10¯⁴ m

Charge (Q) = 5.24×10¯⁹ C

Potential difference (V) = 240 V

Permittivity of free space (ε₀) = 8.85×10¯¹² F/m

Area (A) =?

Thus, the area of the plate can be obtained as follow:

Q = ε₀AV /d

5.24×10¯⁹ = 8.85×10¯¹² × A × 240 / 2.22×10¯⁴

5.24×10¯⁹ = 2.12×10¯⁹ × A / 2.22×10¯⁴

Cross multiply

2.12×10¯⁹ × A = 5.24×10¯⁹ × 2.22×10¯⁴

Divide both side by 2.12×10¯⁹

A = (5.24×10¯⁹ × 2.22×10¯⁴) / 2.12×10¯⁹

A = 5.49×10¯⁴ m²

Thus, the area of the plates is 5.49×10¯⁴ m².

The addition of two sound waves produces a new wave of higher amplitude if their compressions and refractions line up. It is also known as constructive interference.

Interference can be described as a phenomenon in which two waves combine by adding at every single point in space and time, to form a resultant wave of greater or lower amplitude.

Constructive and destructive interference occurs in the interaction of waves that are correlated with each other because they come from the same source.

When two sound waves propagate in the same direction in phase with each other, their amplitude gets added, and the resultant wave is produced from constructive interference.

When two waves interfere with each other and have a displacement in the opposite direction.  When a crest of a wave meets the trough of another wave, the waves undergo destructive interference.

Answer:

i) 3.514 s, ii) 5.692 m/s

Explanation:

i) We can use Newton's second law of motion to find out how long does it take for the Eagle to touch down.

as the equation says for free-falling

h = ut +0.5gt^2

Here, h = 10 m, g = acceleration due to gravity = 1.62 m/s^2( on moon surface)

initial velocity u = 0

10 = 0.5×1.62t^2

t = 3.514 seconds

Therefore, it takes t = 3.514 seconds for the Eagle to touch down.

ii) use Newton's 1st equation of motion to calculate the velocity of the lunar module when it hits the surface of the moon

v = u + gt

v = 0+ 1.62×3.514

v= 5.692 m/s

Answer:

a. The final speed , v' when it returns is the same speed, u as when it was released. v' = u

b. The time of flight T equals twice the time taken to reach the highest point, t. T = 2t

Explanation:

(a) As long as you can neglect the effects of the air, if you throw anything vertically upward, it will have the same speed when it returns to the release point as when it was released.

Using v² = u² - 2gh, we find the maximum height the object reaches. With u = initial vertical velocity, v = velocity at maximum height = 0 m/s (since it momentarily stops), g = acceleration due to gravity and h = maximum height

So, v² = u² - 2gh

0² = u² - 2gh

0 = u² - 2gh

-u² = -2gh

h = -u²/-2g

h = u²/2g

On its return trip to the point where it is released, the distance covered is h and its initial velocity u' = 0

With v' as the final velocity, we use

v'² = u'² + 2gh

substituting the values of the variables into the equation, we have

v'² = 0² + 2g(u²/2g)

v'² = 0² + u²

v'² = u²

taking square-root of both sides, we have

√v'² = √u²

v' = u

So, the final speed , v' when it returns is the same speed u as when it was released. v' = u

(b) The time of flight will be twice the time it takes to get to its highest point.

At the highest point, its velocity is zero.

Using v = u - gt where u = initial velocity, v = final velocity(velocity at highest point) = 0 (since it is momentarily at rest), g = acceleration due to gravity and t = time taken to reach the highest point.

So, substituting the values of the variables into the equation, we have

v = u - gt

0 = u - gt

-u = -gt

t = u/g

On its return trip, since we know its final velocity = u and its initial velocity is  0 m/s, again, using

v' = u' + gt' where u' = initial velocity = 0 (since it is at its highest point), v' = final velocity = u (velocity on return to release point), g = acceleration due to gravity and t' = time taken to reach release point from highest point

So, substituting the values of the variables into the equation, we have

v' = u' + gt'

u = 0 + gt'

u = gt'

t' = u/g = t

So, the time of flight, T = time taken to reach highest point + time taken to return to release point

T = t + t'

T = u/g +u/g

T = 2u/g

T = 2t

So, the time of flight T equals twice the time taken to reach the highest point, t. T = 2t

The top move will in a circle because there is tension at the top which will add up with the weight of the toy to maintain equal centripetal force providing the circular motion.

The tension experienced by the top of the vertical circle is calculated by using the following formula.

T = Fc - W

where;

T = mv²/r - mg

where;

The tension experienced by the toy at the top of the vertical circle is calculated as follows;

T = ( 0.15 x 2² / 0.8 ) - ( 0.15 x 9.8 )

T = 0.75 - 1.47

T = -0.72 N

Thus, with the negative tension at the top of the vertical circle, the sum of the tension force and the weight of the toy will be equal to the centripetal force to maintain the orbit of the toy in a circular path.

One point in favor of using nuclear fission to generate electric energy is that it is a relatively low-carbon option, producing fewer greenhouse gas emissions than fossil fuels. However, there are several points against using fission as an energy source. One is that it produces radioactive waste that can be difficult and costly to dispose of safely. Another is that there is the risk of accidents or leaks, which can have serious consequences for both people and the environment. Additionally, the construction of nuclear power plants is expensive and time-consuming, and the plants themselves have a limited lifespan.

The law of motion that accounts for an apple accelerating as it falls from a tree is the law of gravity, specifically Newton's Second Law of Motion.

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In the case of an apple falling from a tree, the net force acting on it is the gravitational force pulling it toward the Earth. The acceleration of the apple is therefore determined by the strength of this gravitational force and the mass of the apple.

As the apple falls from the tree, it accelerates toward the ground due to the gravitational force acting on it. The faster the apple falls, the greater its acceleration. This acceleration is commonly referred to as acceleration due to gravity, which is a constant value of 9.81 m/s^2 near the surface of the Earth.

Answer:

Explanation:

a )

At a point midway between the wires , magnetic field due to two wires will be equal and opposite so they will cancel each other . Therefore , net magnetic field will be zero .

b )

At a point 25cm to the right of point midway between the wires

distance of this point will be .25 m from one wire and .75 m from other wire .

Magnetic field due to a current carrying wire can be given by the following expression .

B = (μ₀ / 4π ) x 2I / R where I is current and R is distance of the point

= 10⁻⁷ x 2I / R

For the wire at a distance of .25 m

magnetic field B₁ = 10⁻⁷ x 2 x 20 / .25

= 160 x 10⁻⁷ T .

For the wire at a distance of .75 m

magnetic field B₂ = 10⁻⁷ x 2 x 20 / .75

= 53.33 x 10⁻⁷ T .

These fields are opposite to each other , so

net magnetic field = 160 x 10⁻⁷ T -  53.33 x 10⁻⁷ T

= 106.67 x 10⁻⁷ T .

If the wires are horizontal and current is flowing away from the observer , net magnetic field will be in vertically upward direction .

c )

At a point 75cm to the right of point midway between the wires

The point will be .25 m from one wire and 1 .25 m from other wire . And the magnetic field will be aligned in the same direction .

For the wire at a distance of .25 m

magnetic field B₁ = 10⁻⁷ x 2 x 20 / .25

= 160 x 10⁻⁷ T

For the wire at a distance of 1.25 m

magnetic field B₂ = 10⁻⁷ x 2 x 20 / 1.25

= 32  x 10⁻⁷ T

As the fields are aligned in the same direction

Net magnetic field =  160 x 10⁻⁷ T + = 32  x 10⁻⁷ T

= 192 x 10⁻⁷ T .

If the wires are horizontal and current is flowing away from the observer , net magnetic field will be in vertically downward direction.
