The magnitude of the electric force is(F) \(79.07\times 10^{-9}\) N and the electric force between the charges is repulsive.

To calculate the magnitude of the electric force that one particle exerts on the other,  we are using the formula,

\(F=k\frac{q_{1} q_{2} }{r^{2} }\)

Here we are given,

\(q_1\)= Charge of the first particle= 7.03nC = \(7.03\times 10^{-9}\)  C.

\(q_2\)=Charge of the second particle = 4.14nC= \(4.14\times 10^{-9}\) C.

r= The distance between two charges=1.82m.

k= Constant of proportionality= \(\frac{1}{4\pi \epsilon}\)=\(9\times 10^{9} Nm^{2} /C^{2}\)

Now we put the known values in the above equation, we get

\(F=k\frac{q_{1} q_{2} }{r^{2} }\)

Or,\(F=9\times 10^{9} \times \frac{7.03\times 10^{-9}\times 4.14\times 10^{-9} }{(1.82)^{2} }\)

Or, F= \(79.07\times 10^{-9}\) N.

From the above calculation we can conclude that the magnitude of the electric force(F) is \(79.07\times 10^{-9}\) N.

Charges \(q_1\) and \(q_2\) is \(79.07\times 10^{-9}\) C and \(4.14\times 10^{-9}\)C respectively, Both charges are positive and have same polarity. The force between the same charges is repulsive.

The magnitude of the velocity at time t=15.0 s will be approximately 44.3 m/s.

To solve this problem, we first need to find the horizontal and vertical components of the projectile's velocity at time t=15.0 s.

Given that the projectile is launched with initial velocity components Vox = 30 m/s and V₀y = 100 m/s, we can use the following kinematic equations to find the velocity components at any time t:

Vx = V₀x (constant)

Vy = V₀y - gt

where g is the acceleration due to gravity (9.8 m/s²).

Using the above equations, we can find the vertical component of the velocity at time t=15.0 s as:

Vy = V₀y - gt = 100 m/s - (9.8 m/s²)(15.0 s) = -32.0 m/s (downward)

Since there is no acceleration in the horizontal direction, the horizontal component of the velocity remains constant throughout the motion. Thus, the horizontal component of the velocity at time t=15.0 s is:

Vx = V₀x = 30 m/s

Now, we can use the Pythagorean theorem to find the magnitude of the velocity at time t=15.0 s:

V = √(V²x+ V²y) = √((30 m/s)² + (-32.0 m/s)²) = 44.3 m/s

Therefore, the magnitude of the velocity at time t=15.0 s is approximately 44.3 m/s.

Answer: B

Explanation: We see the color black when no light is being reflected. Black absorbs all of the light unlike white which reflects all of it.

Answer: A.

Explanation: Because it is like when you rub your knees on a rug it is tensional so that would make it a not active force.

The index of refraction of the unknown substance is approximately 1.00.

When light undergoes total internal reflection at the boundary between two media, it means that the angle of incidence is equal to or greater than the critical angle for that boundary. The critical angle can be determined using Snell's law:

n1 * sin(theta1) = n2 * sin(theta2)

In this case, the incident medium is the unknown substance, and the refractive index of air is approximately 1.00. When total internal reflection occurs, the angle of refraction, theta2, is 90 degrees (perpendicular to the boundary).

sin(theta2) = 1.00 (since sin(90 degrees) = 1.00)

Now, rearranging the equation and substituting the values, we have:

n1 * sin(theta1) = 1.00

The critical angle occurs when sin(theta1) is equal to 1, so:

n1 * 1 = 1.00

Simplifying the equation, we find

n1 = 1.00

Therefore, the index of refraction of the unknown substance is approximately 1.00.

Explanation:

Efficiency is a way of describing the amount of useful ​output​ a process or machine can generate as a percentage of the ​input​ required to make it go. In other words, it compares how much energy is used to do work versus how much is lost or wasted to the environment. The more efficient the machine, the less energy wasted.

For example, if a heat engine is able to turn 75 percent of the fuel it receives into motion, while 25 percent is lost as heat in the process, it would be 75 percent efficient. Out of the original 100 percent of the fuel, 75 percent was output as useful work.  

the equation:

energy efficiency =useful output energy/total input energy

Answer:

Explanation:

Work done on the lever ( input energy ) = force applied x input distance

= 24 N x 2m = 48 J

Work done by the lever ( output energy ) = load x output distance

= 72 N x 0.5m = 36 J

efficiency = output energy / input energy

= 36 J  / 48 J

= 3 / 4 = .75

In percentage terms efficiency = 75 % .

The elevator does 24,000 Joules of work in lifting a 600 N person over a distance of 40 meters.

To calculate the work done by an elevator in lifting a person, we can use the formula:

Work = Force × Distance × cos(θ)

Where:

Force = 600 N (the weight of the person)

Distance = 40 m (the vertical distance the person is lifted)

θ = 0 degrees (cosine of 0 is 1, indicating the force and distance are in the same direction)

Plugging in the values:

Work = 600 N × 40 m × cos(0°)

= 600 N × 40 m × 1

= 24,000 N·m

What do you need help with?

Answer:

Explanation:

A concave mirror is a curved mirror that is coated outwards. The outer part of the mirror is always coated. The nature of image formed by an object placed in front of a concave mirror can be real or virtual depending on the distance of the object on the axis from the mirror. The only time the object produces a virtual image is when it is placed between the focus and the pole of the mirror. The virtual image formed is a "MAGNIFIED and upright image"

For a convex mirror, the inner part is always coated and the nature of the image formed by the object doesn't depend on the distance between the image and the mirror. No matter where the object is placed, the image formed will always be virtual, upright and DIMINISHED. This means that magnification is always less than 1.

For a plane mirror, the nature of the image produced by a plane mirror also virtual because it is always formed behind the mirror. The size of the image formed is always THE SAME as that of the object. This means that the magnification is always equal to 1.

a) In summary, the difference between virtual images produced by concave, plane, and convex mirrors is that virtual images produced by concave mirror are MAGNIFIED, virtual images produced by plane mirror are THE SAME SIZE as that of the object and virtual images produced by convex mirrors are always DIMINISHED.

b) Magnification is defined as the ratio of the image distance to the object distance. Mag = v/u

Note that object distances are always positive, hence it is only the image distance that can either be positive or negative which in turn affects the magnification causing it to be positive or negative.

Negative image distance shows that the image is virtual while positive image distance shows that the image is real.

A negative magnification therefore shows that the nature of the image is a virtual image.

Research conducted by Goodale and colleagues suggests that the primary function of the dorsal stream of the visual cortex is to process visual information for guiding actions and motor control, rather than conscious perception.

Goodale and his colleagues have proposed a theory known as the two-stream hypothesis, which suggests that the visual processing in the brain is divided into two distinct streams: the ventral stream and the dorsal stream.

On the other hand, the dorsal stream, referred to as the "where" or "how" pathway, is primarily involved in processing visual information for the purpose of guiding actions and motor control. This stream is responsible for extracting spatial information, motion perception, and the perception of depth and location of objects in the visual field.

Goodale and his colleagues have provided substantial evidence for this hypothesis through various studies, including patient studies with individuals who have damage to the dorsal stream. These patients often experience impairments in their ability to interact with objects in their visual field, even though their conscious perception of those objects remains intact.
