When does a scatter plot show a correlation?

The total electric field produced by the charges at the midpoint is

8 x 10³ N/C.

Amount of charge on the first particle, q₁ = 40 x 10⁻⁹C

Amount of charge on the second particle, q₂ = 60 x 10⁻⁹C

Distance between the charges, r = 30 cm = 0.3 m

The expression for the electric field due to the charges is given by,

E = 1/4πε₀ x q/r²

At the midpoint between the two charges, d = 0.15 m

So, the electric field produced by the charge q₁ at the midpoint is,

E₁ = 1/4πε₀ x q₁/d²

E₁ = 9 x 10⁹ x 40 x 10⁻⁹/(0.15)²

E₁ = 1.6 x 10⁴ N/C

So, the electric field produced by the charge q₂ at the midpoint is,

E₂ = 1/4πε₀ x q₂/d²

E₂ = 9 x 10⁹ x 60 x 10⁻⁹C/(0.15)²

E₂ = 2.4 x 10⁴ N/C

Therefore, the total electric field produced by the charges at the midpoint is,

E = E₂ - E₁

E = 2.4 x 10⁴- 1.6 x 10⁴

E = 8 x 10³ N/C

Surface area of pyramid 1  539.2 \(m^{2}\) Pyramid 2: 370.9 \(m^{2}\) Pyramid 3: 446.4 \(m^{2}\)

To find the surface area of a pyramid, we need to know the dimensions of its base and its slant height. Assuming the base of each pyramid is a square, we can calculate the surface area using the formula:

Surface Area = Base Area + (0.5 × Perimeter of Base × Slant Height)

Let's calculate the surface area for each pyramid using the given dimensions:

1. Pyramid 1: Base = 12.2 m Slant Height = 16 m Base Area = (12.2 \(m^2\)= 148.84 \(m^2\)Perimeter of Base = 4 × 12.2 m = 48.8 m

Surface Area = 148.84 \(m^2\)+ (0.5 × 48.8 m × 16 m) = 148.84 m^2 + 390.4 \(m^2\) = 539.24 \(m^2\) (rounded to nearest tenth)

2. Pyramid 2: Base = 10.6 m Slant Height = 12.2 m Base Area = (10.6 \(m^2\))= 112.36\(m^2\) Perimeter of Base = 4 × 10.6 m = 42.4 m

Surface Area = 112.36\(m^2\)+ (0.5 × 42.4 m × 12.2 m) = 112.36 \(m^2\)+ 258.56 \(m^2\) = 370.92 \(m^2\)(rounded to nearest tenth)

3. Pyramid 3: Base = 12.2 m Slant Height = 12.2 m Base Area = (12.2 \(m^2\)= 148.84 \(m^2\)Perimeter of Base = 4 × 12.2 m = 48.8 m

Surface Area = 148.84 m^2 + (0.5 × 48.8 m × 12.2 m) = 148.84 \(m^2\)+ 297.52 \(m^2\) = 446.36 \(m^2\) (rounded to nearest tenth)

Therefore, the surface areas of the given pyramids are approximately: Pyramid 1: 539.2 \(m^2\)Pyramid 2: 370.9 \(m^2\) Pyramid 3: 446.4 \(m^2\).

Answer:

Which feature is created when a block of rock dropped down in relation to the block of rock beside it?

Explanation:

Grabens drop down relative to adjacent blocks and create valleys. Horsts rise up relative to adjacent down-dropped blocks and become areas of higher topography.

The wavelength in a vacuum is 5.08 x 10-7  m and the wavelength of the light in the glass is 3.367 x 10-7  m

As we know that

 Velocity = wavelength x frequency

So,    wavelength = Velocity / frequency

If the light travels in a vacuum,

Then,    wavelength = speed of light/frequency

Here  the frequency is 5.9 x1014 Hz  

And the speed of light = 3 x 10 8 m/s

So, wavelength in vacuum = 3 x 10 8 / 5.9 x1014

    = 5.08 x 10-7  m

Again,  the wavelength of the light in the glass

 λ=c/μn            where μ is a block of glass that has an index of refraction

Then  λ=(3 x 10 8 )/(1.51x5.9 x1014 )            

 = 3.367 x 10-7  m

According to the given data in the question, the 15.0 kg mass would be moving at a speed of 6.66 m/s just as the drum gained 350.0 J of kinetic energy on Mars.

Kinetic energy is the energy that a moving physical object has due to its movement. It is defined as the energy an object possesses by virtue of its motion, and is dependent on its mass and velocity.

The kinetic energy gained by the drum is equal to the work done by the falling mass. On earth, the work done is given by:

W = mgh = (15.0 kg)(9.81 m/s²)(5.00 m) = 735.75 J

Since the drum gains 350.0 J of kinetic energy, the efficiency of the system is:

efficiency = 350.0 J / 735.75 J = 0.475

On Mars, the work done by the falling mass must also be equal to 350.0 J, but with a different value of h:

350.0 J = (15.0 kg)(3.71 m/s²)h

h = 26.0 m

Therefore, the 15.0 kg mass must fall through 26.0 m on Mars to give the same amount of kinetic energy to the drum.

The final speed of the mass just as the drum gains 350.0 J of kinetic energy can be found using the formula:

K = (1/2)mv²

where K is the kinetic energy of the mass and v is its final speed. Solving for v:

v = \(\sqrt{(2K/m)}\)

On Mars, with the same efficiency as on earth, the kinetic energy of the mass is also 350.0 J. Therefore:

v = \(\sqrt{(2(350.0 J) / 15.0 kg) }\)= 6.66 m/s

So the 15.0 kg mass would be moving at a speed of 6.66 m/s just as the drum gained 350.0 J of kinetic energy on Mars.

Explanation:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Answer:

5.67 m/s

Explanation:

The speed of a wave can be calculated as the distance traveled by the wave divided by the time taken:

Speed = Distance/Time

In this case, the distance traveled by the wave is the length of the pool, which is 17 m. The time taken by the wave to travel this distance is 3 seconds.

So, the speed of the wave can be calculated as:

Speed = 17 m/3 s

Speed = 5.67 m/s

Therefore, the speed of the water wave in the 17 m long pool is 5.67 m/s.

One stands at the base of a 3.90-m long frictionless ramp that is inclined at an angle of 8.60∘, so one must give the object an initial velocity of 2.29 m/s up the ramp to slide a 1.95-kg object up the ramp.

The potential energy of the object at the top of the ramp = the initial kinetic energy of the object, as the final velocity is zero.

m × g ×h = 1/2 × m × \(v_0^2\)

(m= mass of the object, g = acceleration due to gravity, h = height of the ramp, and \(v_0\) = initial velocity of the object)

\(v_0\) =√2× g ×h

\(v_0\) =√2×  9.81 m/\(s^2\) ×3.90 m× sin(8.60°)

The force exerted by the ball on the glove is 180 Newtons.

In mechanics, a force is any action that has the potential to change, maintain, or deform a body's motion. The three principles of motion outlined by Isaac Newton in his Principia Mathematica are frequently used to illustrate the concept of force (1687).

Newton's first law states that a body at rest or moving uniformly in a straight line will stay in that state until a force is applied to it. According to the second law, a body will accelerate (change in velocity) in the direction of any external force acting on it.

Given:

A baseball (m = 140 g) traveling at 30 m/s moves a fielder's glove backward 35 cm when the ball is caught,

Calculate the value of force as shown below,

Force = m × V² / 2L

Force = 0.140 × 30² / 2 × 0.35

Force = 0.140 × 900 / 0.70

Force = 126 / 0.7

Explanation:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration

The two strings are taut. When the system is released from rest, it accelerates at 2 m/s2 then, Mass of A = 8m/5 kg.

Let the mass of the body A be ‘m’.

The two strings are taut so they exert a tension ‘T’ on body A.

Let ‘a’ be the acceleration produced in the system.

The free body diagram of body A is given below: mA + 2T = mA + ma = mA + m(2)mA + 10T = mA + ma = mA + m(2)

As the two strings are taut, we can say that tension in both strings is equal.

Therefore 2T = 10T or T = 5T As the body A is resting on a smooth horizontal table, there is no friction force acting on the body A.

The net force acting on body A is the force due to tension in the strings. ma = 2T – mg …(1)

As per the given problem, the system is released from rest.

Hence the initial velocity is zero.

Also, we are given that the system accelerates at 2 m/s2.

Therefore a = 2 m/s2 …(2)

From the equations (1) and (2), we get, m(2) = 2T – mg …(3)⇒ m(2) = 2×5m – mg⇒ 2m = 10m – g⇒ g = 8m/5

Thus, the mass of A is 8m/5 kg.

To solve this problem, we need to use Newton's second law to find the net force acting on the two boxes. The net force is equal to the mass of the two boxes times the acceleration. Since the boxes are moving at a constant speed, the acceleration is zero, and the net force is also zero. This means that the sum of all the forces acting on the two boxes must be zero.The force you exert on the boxes is the force of tension in the rope, and this force is equal in magnitude and opposite in direction to the force of friction on the lower box. The magnitude of the friction force on the lower box is equal to the coefficient of kinetic friction times the normal force acting on the lower box.The normal force is the force exerted by the ramp on the lower box, and it is equal in magnitude to the weight of the lower box. The weight of the lower box is equal to the mass of the lower box times the acceleration due to gravity.The magnitude of the friction force on the upper box is equal to the coefficient of static friction times the normal force acting on the upper box. The normal force acting on the upper box is equal in magnitude to the weight of the upper box.Now that we have all the forces, we can use Newton's second law to solve for the force you need to exert. The equation is:F_tension - F_friction_lower = 0

F_tension = F_friction_lowerF_friction_lower = u_k * N_lower

F_tension = u_k * m_lower * gWhere:F_tension is the force you need to exertF_friction_lower is the force of friction on the lower boxu_k is the coefficient of kinetic friction between the ramp and the lower boxN_lower is the normal force acting on the lower boxm_lower is the mass of the lower boxg is the acceleration due to gravitySubstituting the given values, we get:F_tension = (0.444) * (m_lower) * (9.8 m/s^2)The force you need to exert is therefore:F_tension = (0.444) * (m_lower) * (9.8 m/s^2)The magnitude of the friction force on the upper box is:F_friction_upper = u_s * N_upperWhere:F_friction_upper is the force of friction on the upper boxu_s is the coefficient of static friction between the two boxesN_upper is the normal force acting on the upper boxSubstituting the given values, we get:F_friction_upper = (0.800) * (m_upper) * (9.8 m/s^2)The direction of the friction force on the upper box is opposite to the direction of motion of the upper box.
