If the force between two charges with opposite signs is -36 newtons, what is the force between two charges with the same sign?

Answers

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

Solve the speed for the blank this is a PHET LAB​

Answers

Explanation:

The volume of matter contained in an item is measured in kilograms. It claims that a material's rate in velocity is equal to the force exerted and occurs in the force's path.

Speed (Velocity) = Force / Mass

Speed (Velocity) = 25 / 50 = 0.5 m/s

Speed (Velocity) = 50 / 50 = 1 m/s

Speed (Velocity) = 7 / 50 = 1.5 m/s

Speed (Velocity) = 100 / 50 = 2 m/s

Speed (Velocity) = 200 / 50 = 4 m/s

Find the frequency of a 63.8-cm long open end air column
that resonates as shown in the diagram at the right. The speed of sound in the air is 345 m/s.

Answers

Answer:

f = 270.37 Hz

Explanation:

Given that,

The length of the long open end air column, L = 63.8 cm

The speed of sound in the air is 345 m/s

We need to find the frequency of the air column. For an open pipe, the frequency is given by :

[tex]f=\dfrac{nv}{2L}\\\\f=\dfrac{345}{2\times 63.8\times 10^{-2}}\\\\f=270.37\ Hz[/tex]

So, the frequency of the air column is equal to 270.37 Hz.

A 10 kg firework is shot in the air at 75 m/s. What is the momentum of the firework?

Answers

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

A .001 kg bead slides without friction around a loop-the-loop. The bead is released from a height of 20.6 m from the bottom of the loop-the-loop which has a radius 7 m. The acceleration of gravity is 9.8 m/s [photo] What is its speed at point A ? Answer in units of m/s. Your answer must be within ± 5.0%

Answers

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

Cold water flows to the solar panels at 15°C. During the day, the panels supply 3.8 kg of hot water
at 65°C every hour.
(a) Calculate the average energy that the solar panels deliver to the water in one hour.
Specific heat capacity of water = 4200 J/(kg°C). ​

Answers

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.

A bag of marbles is hanging motionless on a spring scale. What prevents the bag from falling?​

Answers

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.

A golfer wants his shot to land
122 m away on flat ground.
His club launches balls at a 55.0°
angle. How fast should
the ball leave the club?
(Unit = m/s)

Answers

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

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.

Answers

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]
