find the volume of the given solid. bounded by the coordinate planes and the plane 8x + 5y + z = 40

Answer:

36 Newtons

Explanation:

The force of attraction or repulsion between two charges can be given by Coulomb's Law:

[tex]F = \frac{kq_1q_2}{r^2}[/tex]

where,

F = Force

k = Coulomb's Constant

q₁ = magnitude of first charge

q₂ = magnitude of second charge

r = distance between charges

Hence, the charges with opposite signs will produce a result with a negative value. While, the charges with same sign will produce positive result of force value.

Hence, the force between two charges with the same sign will be 36 Newtons

Answer:

1)the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That's very cold, and there's no way liquid water could exist.

2)Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).

3)To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit,

Answer:

Momentum = 750 Kgm/s

Explanation:

Given the following data;

Mass = 10 kg

Velocity = 75 m/s

To find the momentum;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

Substituting into the formula, we have;

Momentum = 10 * 75

Momentum = 750 Kgm/s

Answer:

La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]

Explanation:

La velocidad es una magnitud física que expresa la relación entre el espacio recorrido por un objeto y el tiempo empleado para ello.

La velocidad media relaciona el cambio de la posición con el tiempo empleado en efectuar dicho cambio. Por lo que se calcula como la distancia recorrida por un objeto dividido por el tiempo transcurrido:

[tex]velocidad=\frac{distancia}{tiempo}[/tex]

En este caso:

Entonces, reemplazando en la definición de velocidad media:

[tex]velocidad=\frac{10 km}{2 h}= \frac{10,000 m}{7,200 s}[/tex]

Resolviendo se obtiene:

[tex]velocidad=5 \frac{km}{h}= 1.389\frac{m}{s}[/tex]

La velocidad media es 5 [tex]\frac{km}{h}[/tex], que equivale a 1.389 [tex]\frac{m}{s}[/tex]

Answer:

35.67 m/s

Explanation:

Applying the formular for range,

R = u²sin2∅/g....................... Equation 1

Where R = Range, u = Initial Velocity, ∅ = angle of launch, g = acceleration due to gravity

make u the subject of the equation

u = √(Rg/sin2∅)............. Equation 2

Given: R = 122 m, g = 9.8 m/s², ∅ = 55°

Substitute these values into equation 2

u = √[(122×9.8)/(sin(2×55))]

u = √(1195.6/sin110)

u = √(1272.33)

u = 35.67 m/s

Answer:

The average energy that the solar panel delivers to the water in one hour is 798,000 Joules

Explanation:

The given parameters are;

The temperature of the water that flows to the solar panels, T₁ = 15°

The mass of the hot water the panel supplies during the day, m = 3.5 kg

The temperature of the hot water supplied by the panel, T₂ = 65 °C

The heat capacity of the water, c = 4,200 J/(kg·°C)

The heat delivered to the solar panels in one hour, ΔQ, is given by the following formula

ΔQ = m·c·ΔT

m = 3.8 kg, c = 4,200 J/(kg·°C), and ΔT = T₂ - T₁ = 65 °C - 15 °C = 50 °C

∴ ΔQ = 3.8 kg × 4,200 J/(kg·°C) × 50°C = 798,000 joules

∴ΔQ = 798,000 joules

The average energy that the solar panel delivers to the water in one hour, ΔQ = 798,000 joules.

Answer:

 t_man = 10.16 s,   t_horse = 10.73 s,  the winner is the man

Explanation:

To solve this problem we are going to find the time of each one separately.

Man we look for distance and time during acceleration

         x₁ =  v₀ t₁ + ½ a₁ t₁²

as it comes out of rest its initial velocity is zero

        x₁ = ½ a₁ t₁²

        x₁ = ½ 6.0 1.8²

        x₁ = 9.72 m

at this point its speed is

        v₁ = v₀ + a t

        v₁ = 0 + 6  1.8

        v₁ = 10.8 m / s

From here on it continues at constant speed, the distance that the man needs to travel from the point where the man leaves at 100m is

        x₂ = 100 - x₁

        x₂ = 100- 9.72

        x₂ = 90.28 m

the time for this part is

        v₁ = x₂ / t₂

         t₂ = x₂ / v₂

         t₂ = 90.28 / 10.8

         t₂ = 8.36 s

the total time for the man is

        t_man = t₁ + t₂

        t _man = 1.8 + 8.36

        t_man = 10.16 s

We repeat the calculation for the horse

distance traveled during the acceleration period

         x₃ = v₀ t + ½ a₂ t₃²

as part of rest its initial velocity is zero

        x₃ = ½  a₂ t₃²

        x₃ = ½  5.0  4.8²

        x₃ = 57.6 m

the velocity at this point is

         v₃ = v₀ + a₂ t₃

         v₃ = 0 + 5  4.8

         v₃ = 24 m / s

the rest of the route is at constant speed, the remaining distance

         x₄ = 200 - x₃

         x₄ = 200 - 57.6

         x₄ = 142.4 m

the time to go through it is

         t₄ = x₄ / v₃

         t₄ = 142.4 / 24

         t₄ = 5.93 s

the total time for the horse is

         t_horse = t₃ + t₄

         t_horse = 4.8 + 5.93

         t_horse = 10.73 s

when we compare the times we see that the man arrives a little before the horse, the winner is the man

Explanation:

The law of superposition.

Answer:

Explanation:

Given that:

angular frequency = 11.3 rad/s

Spring constant (k) = [tex]= \omega^2 \times m[/tex]

k = (11.3)² m

k = 127.7 m

where;

[tex]x_1[/tex] = 0.065 m

[tex]x_2[/tex]  = 0.048 m

According to the conservation of energies;

[tex]E_1=E_2[/tex]

∴

[tex]\Big(\dfrac{1}{2} \Big) kx_1^2 =\Big(\dfrac{1}{2} \Big) mv_2^2 + \Big(\dfrac{1}{2} \Big) kx_2^2[/tex]

[tex]kx_1^2 = mv_2^2 + kx_2^2[/tex]

[tex](127.7 \ m) \times 0.065^2 = v_2^2 + (127.7 \ m) \times 0.048^2[/tex]

[tex]0.5395325 = v_2^2 +0.2942208 \\ \\ 0.5395325 - 0.2942208 = v_2^2 \\ \\ v_2^2 = 0.2453117 \\ \\ v_2 = \sqrt{0.2453117} \\ \\ \mathbf{ v_2 \simeq0.50 \ m/s}[/tex]

Answer:

[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]

Explanation:

Given

[tex]0.00074m[/tex]

Required

Express as scientific notation

The scientific notation of a number is: [tex]a * 10^{b}[/tex]

Where [tex]1 \le a \le 9[/tex]

This implies that:

[tex]0.00074m = 7.4 * 10^b[/tex]

Next, is to determine the value of b.

Count the number of point to move from the current point location to 7.4.

If the point moves backward, b will be negative, else b will be positive.

So:

[tex]0.00074m[/tex]      [tex]b=-4[/tex]

Hence:

[tex]0.00074m[/tex] [tex]=[/tex] [tex]7.4*10^{-4}m[/tex]

Answer:

Girls, we found one.

The "uwu pwease pwotect me, waifu" 'nice guy' that tries convincing naive girls to send inappropriate pictures within 2 hours of knowing them because he "in love" them.

The reality of the situation is the dude is very desperate and wants to project their anime girl fantasies onto a girl that pities them because "gwuys are mwean" to them.

Step-by-step explanation:

You're 16, kid. Two years until you're 18. Just say you want a weeb girl/friend. no need to try and draw pity from little girls and use that to manipulate them. If you said this when you were 12, it would be excusable. But you're 16. If you want to attract girls, don't use pity. Or try to type words in a cutesy manner, that's just very unattractive and makes you seem desperate.

Answer:

the statement is FALSE

Explanation:

To answer this question we use that thermodynamic energy is

           E = K T

also according to the Planck relation

          E = h f

the speed of light et related to frequencies and wavelength

          c = λ f

          f = c /λ

we substitute

           hc /λ = KT

           λ= hc / k T

calculate us

           lam = 6.62 10⁻³⁴ 3 10⁸ / 1.381 10⁻²³ 5400

           lam = 2,663 10⁻⁸ m

let's reduce to num

         lam = 2,663 10  

         lam = 26,63 nm

This wavelength is in the farultraviolet, therefore the statement is FALSE

Explanation:

Because of static friction between two surfaces

Answer:

11.37 m/s

Explanation:

We are given;

Mass; m = 0.001 kg

Initial velocity; v1 = 0 m/s (since it was released from rest)

Initial height; h1 = 20.6m

From the attached image of the bead in the loop, we can see that height at A; h2 = twice the radius = 2R = 2 × 7 = 14 m

g = 9.8

To solve for the speed at point, we will use formula for conservation of energy. Thus;

½m(v1)² + mgh1 = ½m(v2)² + mgh2

Divide through by m to get;

½(v1)² + gh1 = ½(v2)² + gh2

Plugging in the relevant values;

½(0²) + (9.8 × 20.6) = ½(v2)² + (9.8 × 14)

Rearranging, we have;

½(v2)² = ½(0²) + (9.8 × 20.6) - (9.8 × 14)

Simplifying, we have;

½(v2)² = 64.68

Multiply both sides by 2 to get;

(v2)² = 2 × 64.68

(v2)² = 129.36

v2 = √129.36

v2 = 11.37 m/s

Answer:

The vector sum of all forces acting on it is zero, its at equilibrium.

Explanation:

The bag of marbles hanging on a spring scale applies its weight downwards, which was counterbalanced by the reaction from the spring scale (obeying the Newton's third law of motion). And since no external forces are applied to the system, thus the equilibrium of the system.

If the weight of the bag is greater than the reaction from the spring scale, the scale breaks and the system would not be balanced.
