How do you find distance from average velocity and time

the time required for a displacement of 1.00 m for an electron traveling at a uniform velocity of 1.3 x \(10^{5}\) m/s is approximately 7.69 x \(10^{-7}\)seconds.

To find the time required for a displacement of 1.00 m, we can use the formula:

time = displacement ÷ velocity

Substituting the values, we have:

time = 1.00 m ÷ 1.3 x \(10^{5}\) m/s

time = 7.69 x \(10^{-7}\) seconds

this calculation demonstrates the extremely short time scales involved in the motion of electrons, which can move extremely quickly due to their small size and mass.

In Geometry, the exterior of a circle is defined as all the points outside the circle, that is, it is the set of all points that are not contained within the circle. The boundary of a set is the set of points that are the limit points of the set but are not contained within it. Therefore, the exterior of C cannot be convex.

A limit point of a set is defined as a point such that every neighborhood of that point contains at least one point in the set.

Since the circle C is a closed set, it follows that all limit points of C belong to C.

Any point that is a limit point of the exterior of C must lie on the boundary of C since it is not contained within C.

Hence, we can conclude that the exterior of C has C as its boundary.

(b) To prove that the exterior of C cannot be convex, let us recall the definition of a convex set. A set is said to be convex if any two points in the set can be connected by a straight line that is contained entirely within the set.

Now, let's consider two points that are outside the circle C.

Since the exterior of C is the set of all points outside the circle C, these two points belong to the exterior of C.

Therefore, the exterior of C cannot be convex.

Start with the atom diameter being as large as possible and interaction strength being as weakas possible.

What size are the force arrows in the middle of the atoms is small.

The atomic diameter is the distance across the nucleus, measured in picometers (pm). The nucleus is at the core of the atom. It consists of protons and neutrons. The electrons circle the nucleus in shells or energy levels, which are shown as circles around the nucleus in atomic models.Atomic radius is a term that is often used synonymously with atomic diameter. The atomic radius is the distance from the center of the nucleus to the outermost shell of electrons, which determines the size of an atom.

The interaction strength refers to how strong the bonds are between atoms. The stronger the interaction, the closer the atoms are, and the harder it is to pull them apart. In comparison, if the interaction is weaker, the atoms are farther apart, and they can be pulled apart more easily. Consequently, if the atom diameter is large and the interaction strength is weak, the size of the force arrows in the middle of the atoms is small.

To find the wavelength of an electron that has been accelerated to a speed of 2.1 x 10^7 m/s, we can use the de Broglie equation:

wavelength = h / mv

where h is Planck's constant (6.626 x 10^-34 J*s), m is the mass of the electron (9.11 x 10^-28 g), and v is the velocity of the electron (2.1 x 10^7 m/s).

The area of the shaded region is 4621.5 cm2 - 1083.8 cm2 = 3537.7 cm.

Area is the space or size of a two-dimensional surface or shape. It is a measure of the size of a surface and is typically expressed in square units, such as square feet or square meters. Area is usually calculated by multiplying the length of a shape by its width. For example, the area of a rectangle with a length of 4 feet and a width of 3 feet is 12 square feet. Area can also be calculated for shapes with curved sides such as circles, triangles, and other polygons.

The shaded region is the area between the two circles. To calculate the area of the shaded region, we need to subtract the area of the inner circle from the area of the outer circle.

The area of the outer circle can be calculated using the formula A = πr2, where r is the radius of the circle. Since the two circles have the same center, the radius of the outer circle is twice the radius of the inner circle.

Therefore, the radius of the outer circle is 2 × (117.436/2π) = 38.212 cm.

The area of the outer circle is A = π × 38.212^2 = 4621.5 cm2.

The area of the inner circle can be calculated using the same formula: A = πr2. The radius of the inner circle is (117.436/2π) = 18.606 cm.

The area of the inner circle is A = π × 18.606^2 = 1083.8 cm2.

Two balls of equal mass, moving with & speed of 3.0 m/s, for perfectly elastic collision, the final velocity of each ball is 1.5 m/s. For inelastic collision, the final velocity of each ball is -0.5 m/s and 6.5 m/s.

Given: Two balls of equal mass, moving with speed of 3.0 m/s

To find: Velocity of each after impact for inelastic and perfectly elastic collisions

Let the initial velocities of the two balls be u1 and u2 and final velocities after impact be v1 and v2 respectively.

In both cases, the total momentum of the system before the collision is

P1 = m u1 + m u2

Where m is the mass of each ball.

Using conservation of momentum, we have

P1 = P2

Where P2 is the total momentum of the system after the collision.

a) For inelastic collision, the balls stick together after collision, so their final velocity is the same.

Thus, we have

m u1 + m u2 = (m + m) v

Simplifying, we get

v = (u1 + u2)/2

Therefore, the final velocity of each ball is 1.5 m/s.

b) For perfectly elastic collision, the kinetic energy of the system is conserved, so we have

(1/2) m \(u1^{2}\) + (1/2) m \(u2^{2}\) = (1/2) m \(v1^{2}\) + (1/2) m \(v2^{2}\)

And also, conservation of momentum

m u1 + m u2 = m v1 + m v2

We can solve these equations simultaneously to get the final velocities

v1 = (u1 - u2)/2

v2 = (u2 - u1)/2

Therefore, the final velocity of each ball after perfectly elastic collision is

v1 = -0.5 m/s

v2 = 6.5 m/s (in the opposite direction)

Answer:

Wind

Explanation:

I had this question on one of my tests, and I got it right

Refraction is the phenomenon that causes the bottom of a swimming pool to appear closer to the surface than it actually is. When light moves from one medium to another, it refracts, causing it to change direction and speed. Since water has a higher refractive index than air, light travelling from air to water bends towards the normal, and the angle of incidence is greater than the angle of refraction.

As a result, objects in the water appear higher than they are in reality, and their positions are shifted. Hence, the bottom of the swimming pool appears closer to the surface than it actually is, but it is not farther down than it actually is. Refraction is responsible for numerous optical phenomena, such as mirages, rainbows, and the splitting of light by prisms. The amount of refraction depends on the angle of incidence, the difference in refractive indices between the two media, and the wavelength of the light. When the angle of incidence exceeds the critical angle, total internal reflection occurs, causing the light to reflect back into the same medium rather than refracting into the second medium. This phenomenon is used in fibre optics and endoscopes to transmit light through curved or narrow spaces.h

The Earth-Venus radar signal takes approximately 149.8 seconds (or about 2 minutes and 29.8 seconds) to complete its round trip when Earth and Venus are at their closest to one another (0.3 A.U.).

To calculate the time it takes for an Earth-Venus radar signal to complete its round trip, we need to consider the distance between Earth and Venus and the speed of light.

The average distance from Earth to the Sun is defined as 1 Astronomical Unit (A.U.), which is approximately 149.6 million kilometres.

When Earth and Venus are at their closest, the distance between them is 0.3 A.U. Multiplying this distance by the average distance between Earth and the Sun gives us the actual distance between Earth and Venus during this time.

Distance = 0.3 A.U. * 149.6 million kilometers

Next, we need to consider the speed of light, which is approximately 299,792 kilometres per second. Since the radar signal travels at the speed of light, we can divide the distance by the speed of light to find the time it takes for the signal to complete its round trip.

Time = Distance / Speed of light

Let's calculate it:

Distance = 0.3 A.U. x 149.6 million kilometers = 44.88 million kilometers

Time = 44.88 million kilometres / 299,792 kilometres per second

Time ≈ 149.8 seconds
