Answer:

a.  -6.99 × 10³⁰ C/m³ b. The layer of air is negatively charged.

Explanation:

With E₁ = electric field at 500 m above the ground = 160 N/C (it is negative since it is directed downwards).

Also, with E₂ = electric field at 800 m above the ground = 120 N/C (it is negative since it is directed downwards).

The total flux, Ψ = ∫E.dA = E₁dAcosθ + E₂dAcosθ

For the 800 m surface E is parallel to dA, that is = 0° and For the 500 m surface E is anti-parallel to dA, that is = 180°  

Ψ = ∫E₁dAcos180° + ∫E₂dAcos0°

= -∫E₁dA + ∫E₂dA

= -E₁∫dA + E₂∫dA

= -E₁4πR² + E₂4πR²

= (-E₁ + E₂)4πR² where R = radius of earth = 6.4 × 10⁶ m

= (-160 N/C + 120 N/C)4π(6.4 × 10⁶ m)²

= - 40 N/C)4π(6.4 × 10⁶ m)²

= -20588.74 × 10¹² C

= -2.058874 × 10¹⁶ C

≅ -2.06 × 10¹⁶ Nm²/C.

The since charge, Q = Ψ/ε₀, the total charge through the area is thus

Q = Ψ/ε₀

= -2.06 × 10¹⁶  Nm²/C ÷ 8.854 × 10⁻¹² F/m

= -0.233 × 10²⁸ C/m²

= -2.33 × 10²⁸ C/m².

So, the charge in the volume = charge net charge of surface × width of volume. So the charge in the volume Q' = QΔh = Q(h₂ - h₁) where h₁ = 500 m and h₂ = 800 m

Q' = Q(h₂ - h₁)

=  -2.33 × 10²⁸ C/m²(800 m - 500 m)

= -2.33 × 10²⁸ C/m²(300 m)

= -699 × 10²⁸ C/m³

= -6.99 × 10³⁰ C/m³

b. Since Q' = -6.99 × 10³⁰ C/m³, the layer of air is negatively charged.

Answer: Newtons second law of motion: the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.

Explanation:

Hope this helps you! Have a good day!

Answer:

Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.

Example:Newton's Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

A) Minimum recommended spiral parameter: 150.03m.

b) Distance P: 150.03m.

c) Distance Q: 4.122m.

d) Angle Φs: 16°30'14.0".

e) Distance Tc: 150.03m.

a) Calculation for the minimum recommended spiral parameter:

Design radius (R) = 300 m

Maximum superelevation (e_max) = 0.06 m/m

Spiral Parameter (A) = (R + e_max) / 2

A = (300 m + 0.06 m/m) / 2

A ≈ 150.03 m

b) Calculation for the distance P:

Distance P is equal to the length of the first spiral curve, which is the same as the minimum recommended spiral parameter.

P ≈ 150.03 m

c) Calculation for the distance Q:

Distance Q represents the length of the circular curve. It is given by the formula:

Q = (Deflection angle at Point of Intersection) / (Degree of Curve, D)

Deflection angle at Point of Intersection = 16°30'14.0"

Converting the angle to decimal degrees:

16° + (30'/60) + (14.0"/3600) = 16.504°

Q = 16.504° / (360° / D)

Q ≈ D / 21.814

Since the RAU80 has 4 lanes, the degree of curve (D) is 360° / 4 = 90°.

Q ≈ 90° / 21.814

Q ≈ 4.122 m

d) Calculation for the angle Φs:

The angle Φs is the deflection angle at the Point of Intersection.

Φs = 16°30'14.0"

e) Calculation for the distance Tc:

Distance Tc is equal to the length of the second spiral curve, which is the same as the minimum recommended spiral parameter.

Tc ≈ 150.03 m

The correct answer to the question is (b) Convert some other form of energy into electrical.

The basic function of an electromotive force in a circuit is to convert some other form of energy into electrical energy. This is achieved through the movement of charged particles, such as electrons, which create a flow of current in the circuit. Electromotive force is commonly represented by the symbol "EMF" and is measured in volts.

An EMF can be generated by various sources, including batteries, generators, and solar cells. In each case, the EMF converts some form of energy (chemical, mechanical, or radiant) into electrical energy that can be used to power devices or perform work.

It is important to note that an EMF does not create energy, but rather it converts energy from one form to another. For example, a battery does not create energy, but instead it converts chemical energy into electrical energy. Similarly, a generator converts mechanical energy into electrical energy.

The average speed of the dog is  6.8 m/s  while the average velocity is 6.8 m/s halfway to the starting point.

The speed of a moving object is the ratio of the distance covered by the object and the time taken to cover the distance. The average speed is the ratio of the total distance traveled and the total time taken.

Velocity, on the other hand, refers to the speed in a particular direction. In other words, velocity is a vector quantity while speed is a scalar quantity.

In this case:

Total distance covered = 50 + 25

                                       = 75 meters

Total time taken = 7.2 + 3.85

                           = 11.05 seconds

This is a defective question. It was WRITTEN by someone who is unclear on the concepts.  DON'T try and answer it.

But that only tells us how much force must act ON THE CAR in order to accelerate it. (45 kg) • (4 m/s^2) = 180 newtons.

This is NOT the force exerted BY the car when it hits something. THAT force depends on its speed WHEN it hits, AND how long it takes for the wreckage to actually come to rest, AND how hard or soft the wall is.

Alice is weightless because she is in free fall.

Free-fall occurs when an object is experiencing the force of gravity but is not experiencing any other forces, such as air resistance. Because Alice is in a spacecraft, air resistance is not a factor, so she is essentially in a vacuum.

When an object is in a vacuum, the only force acting upon it is gravity. Therefore, Alice is in free fall and is experiencing weightlessness. This is in contrast to you, who is experiencing 1g of acceleration due to the force of the engine of your spacecraft.

This force is greater than the force of gravity, so you are not in free fall, and thus you are feeling the effects of the gravitational field.

B = 25°

C = 65°

D = 25°

Explanation:

The given parameters are;

The orientation of the two mirrors = At right angle to each other

The laser light is directed at one of the mirror

The measure of angle, A = 25°

The measures of angle B, C, and D are found as follows;

We have;

∠A = ∠B = 25°, by angle of incidence equals angle of reflection

∠B = 25°

∠B + ∠C = 90° by sum of the acute angles of a right triangle

25° + ∠C = 90°

∴ ∠C = 90° - 25° = 65°

∠C = 65°

∠E = ∠C = 65° by angle of incidence equals angle of reflection

∴ ∠E = 65°

Line 'L' is perpendicular to the second mirror, therefore, the angle between line 'L' and the second mirror = 90° = ∠E + ∠D

∠E + ∠D = 90°,  by angle sum property

Therefore;

65° + ∠D = 90°

∴ ∠D = 90° - 65° = 25°

∠D = 25°

If you tend to be absent-minded, the theory of forgetting that is probably to blame is the Encoding Failure Theory. According to this theory, forgetting occurs when information is not properly encoded or stored in memory. In other words, if you are absent-minded and have trouble remembering things, it is likely because you did not pay enough attention to the information in the first place.

Encoding is the process of transforming sensory input into a form that can be stored in memory. If information is not attended to and processed deeply, it will not be encoded properly, leading to difficulties in retrieval and remembering. Therefore, if you tend to be absent-minded, it is essential to ensure that you are paying adequate attention to the information you want to remember.

Furthermore, it is important to note that factors such as stress, sleep deprivation, and lack of concentration can also contribute to encoding failure and forgetfulness. Thus, practicing good study habits, getting enough rest, and reducing stress can improve memory encoding and help reduce forgetfulness.
