The magnitude of the change in momentum after completing half a revolution is zero,The correct answer is option(a).

To determine the magnitude of the change in momentum after completing half a revolution, we need to consider the principles of circular motion and conservation of momentum.

The change in momentum of an object is given by the equation Δp = mΔv, where Δp represents the change in momentum, m is the mass of the object, and Δv is the change in velocity.

In this scenario, the body of mass 0.1 kg is moving in a uniform circular path with a speed of 2 m/s. Since the speed remains constant, there is no change in velocity during the circular motion. Therefore, Δv is equal to zero.

Applying the equation Δp = mΔv, we find that Δp = (0.1 kg)(0) = 0 kg·m/s.

It's important to note that while the body is continuously changing its direction during the circular motion, the magnitude of its velocity remains constant. As a result, there is no change in momentum, as indicated by the answer (a) zero.

In the actual case where there is water inside the eye, the lens needs to be stronger than if there were only air in our eyes.

This is because the refractive index of water is higher than that of air, meaning that light will bend more when it passes through water than when it passes through air. This makes it harder for the eye to focus light onto the retina, and so a stronger lens is needed to compensate for this increased bending.

If there is also water outside the eye, such as when we are underwater, we need to wear goggles to provide a layer of air in front of our eyes, which allows light to be refracted less and therefore makes it easier to see clearly.

The mass and weight of object on moon is 0.0138kg  and 0.0229kg .

Since force is a vector quantity, we must consider the direction in which it acts. There are two main types of frictional force: static force (Fst) and sliding force (Fsl). Normal forces (FN) produce these forces acting perpendicular to the direction of motion, although they act in the opposite direction to the object's motion.

It is equivalent to the weight of the object plus the extra weight. For example, pushing down on a block of wood on a table increases the normal force and thus the frictional force.

While physical and genetic maps measure distances between genes, they can look different because physical maps reflect the physical structure of DNA, while genetic maps represent the recombination frequencies and genetic linkage relationships between genes. Therefore, the two types of maps may have different scales and arrangements, even though they measure distances in the same units.

Question 6: The statement that the map must have been made incorrectly because the distances do not add up perfectly is not accurate. Genetic mapping is a technique used to estimate distances between genes or genetic markers based on recombination frequencies. The distances obtained through genetic mapping are statistical estimates and are subject to some degree of error and variation. Therefore, it is expected that the sum of distances between multiple points on a map may not always match the direct distance between those points. This is because the estimation of distances is based on the frequency of recombination events that occur during genetic recombination.

Question 7: The statement that the most abundant class in a three-point mapping cross is the double crossovers followed by single crossovers and then no crossovers is false. In a three-point mapping cross, the most abundant class is typically the non-recombinant progeny (no crossovers), followed by the single crossovers, and then the least abundant class is the double crossovers. This pattern is based on the principle of independent assortment and the occurrence of recombination events during meiosis. Non-recombinant progeny result from chromosomes maintaining their original configuration, while single crossovers occur when one recombination event takes place between two of the three loci. Double crossovers involve recombination events at two locations, resulting in a different chromosome configuration. Double crossovers are relatively less frequent compared to single crossovers and non-recombinant progeny.

Question 8: The statement that a physical map and genetic map utilize the same units but may look very different is true. Physical maps and genetic maps are two different types of maps used in molecular biology and genetics. They measure distances between genes or genetic markers, but they do so using different approaches and units.

A physical map represents the physical distances between genes or markers along a DNA molecule or chromosome. It is based on direct measurement of physical lengths, such as base pairs or kilobases. Physical maps provide information on the actual physical locations of genes or markers.

On the other hand, a genetic map represents the relative distances between genes or markers based on recombination frequencies. Genetic maps are constructed using genetic crosses and analysis of recombination events. The units used in genetic mapping are usually centimorgans (cM) or map units.

While physical and genetic maps measure distances between genes, they can look different because physical maps reflect the physical structure of DNA, while genetic maps represent the recombination frequencies and genetic linkage relationships between genes. Therefore, the two types of maps may have different scales and arrangements, even though they measure distances in the same units.

1.67 m From the center of a frictionless playground, 23.9-kg boy stands  merry-go-round, with a moment of inertia of 221.3 kg m2. The boy begins to run in a circular path with a speed of 0.71 m/s relative to the ground. Then the angular velocity of the merry-go-round is  0.23 rad/s.

Initially, the merry-go-round is at rest, so its angular momentum is zero. The boy's angular momentum is given by:

L = Iω

where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.

Substituting the values given in the problem, we have:

L = (221.3 kg\(m^2\)) ω

When the boy starts running, he also starts rotating around the center of the merry-go-round. Since the playground is frictionless, there is no external torque acting on the system, so the angular momentum is conserved.

At the final state, the boy and the merry-go-round are rotating together, so their angular momentum add up:

Lfinal = (221.3 kg\(m^2\) + mboy\(r^2\)) ωfinal

where mboy is the mass of the boy, r is his distance from the center, and ωfinal is the final angular velocity of the system.

Substituting the values given in the problem, we have:

(221.3 kg\(m^2\)) ω = (221.3 kg \(m^2\)+ (23.9 kg)\((1.67 m)^2\)) ωfinal

Simplifying and solving for ωfinal, we get:

ωfinal = ω (221.3 kg\(m^2\)) / (221.3 kg \(m^2\) + (23.9 kg)\((1.67 m)^2\))

Substituting ω = v / r, where v is the boy's speed relative to the ground and r is his distance from the center, we have:

ωfinal = (0.71 m/s) / 1.67 m (221.3 kg \(m^2\)) / (221.3 kg\(m^2\) + (23.9 kg)\((1.67 m)^2\))

Simplifying and solving, we get:

ωfinal = 0.23 rad/s

Therefore, the angular velocity of the merry-go-round is 0.23 rad/s.

Approximately \(5.76 \times 10^{-18}\; {\rm J}\) (by the external force that moved the electron.)

Explanation:

Let \(q\) denote the magnitude of a charge in an electric field of magnitude \(E\). The magnitude of the electrostatic force on that charge would be:

\(F = q\, E\).

In the electric field in this question, the magnitude of the electric force on the electron would be:

\(\begin{aligned}F &= q\, E \\ &= 1.6 \times 10^{-19}\; {\rm C} \times 600\; {\rm N \cdot C^{-1}} \\ &= 9.6 \times 10^{-17} \; {\rm N}\end{aligned}\).

Moving the electron to the other plate would thus require an external force of \(9.6 \times 10^{-17}\; {\rm N}\).

This force needs to be exerted over a distance of \(6.0\; {\rm cm}\) (\(6.0 \times 10^{-2}\; {\rm m}\).) The direction of the motion is the same direction as that of the external force. Thus, the work that needs to be done would be:

\(\begin{aligned}W &= F\, s \\ &\approx 9.6 \times 10^{-17}\; {\rm N} \times 6.0 \times 10^{-2}\; {\rm m} \\ &\approx 5.76 \times 10^{-18}\; {\rm J}\end{aligned}\).

An example of the first law of thermodynamics in action is a car engine, that converts chemical energy to mechanical energy to power its motion.

The first law of thermodynamics, also known as the law of conservation of energy, states that the total energy of a closed system remains constant, which means energy can only be converted and not made or destroyed.

In this process, the fuel is burned in the engine, releasing heat energy that is used to increase the temperature and pressure of the gases in the engine cylinder. The expanding gases then push a piston, converting the heat energy into mechanical work to turn the car's wheels.

Although some of the energy is lost to the environment as waste heat, the total energy of the system remains constant, demonstrating the first law of thermodynamics in action.

False. Adding white to a color produces a tint, while adding black to a color creates a shade.

When we talk about colors, the terms “tint” and “shade” refer to specific changes in their appearance. Adding white to a color creates a tint. This happens because white is the lightest color and has the ability to lighten other colors. When white is mixed with a color, it increases the lightness and creates a paler version of that color. Tints are often associated with a softer and more delicate aesthetic.

On the other hand, adding black to a color creates a shade. Black is the darkest color and has the ability to darken other colors. When black is mixed with a color, it reduces the lightness and creates a darker version of that color. Shades tend to have a deeper, richer, and more intense appearance compared to the original color.

Answer:

B, A, C

Explanation:

The momentum is equal to the mass times the velocity, so for each car the momentum is equal to

Car A

Momentum = Mass x Velocity

Momentum = 1,500 kg x 10 m/s

Momentum = 15,000 kg m/s

Car B

Momentum = Mass x Velocity

Momentum = 1,500 kg x 25 m/s

Momentum = 37,500 kg m/s

Car C

Momentum = Mass x Velocity

Momentum = 1,000 kg x 10 m/s

Momentum = 10,000 kg m/s

Then, the decreasing momentum is B, A, C because

37,500 is greater than 15,000 and 15,000 is greater than 10,000

So, the answer:

B, A, C

(a) The velocity of the object at time t is given by finding the derivative of y (t):

y(t) = -2t2 + t + 10dy(t)/dt

= -4t + 1

Therefore, the velocity of the object at time t is -4t + 1.

(b) The acceleration of the object at time t is given by finding the derivative of the velocity function:

dy(t)/dt = -4t + 1d2y(t)/dt2

= -4

Therefore, the acceleration of the object at time t is -4 m/s2.

(c) The ball hits the ground when y(t) = 0, so we can solve for t by setting -2t2 + t + 10 = 0 and using the quadratic formula:

t = (-b ±  (b2 - 4ac)) / (2a), where a = -2, b = 1, and c = 10.

Plugging these values into the formula, we get:

t = (-1 ±  (12 - 4(-2)(10))) / (2(-2)) = (1 ±  81) / 4

We take the negative root because the positive root corresponds to the ball reaching its maximum height before falling back down. Thus,

t = (1 - 81) / 4

= -2/4

= -0.5 s

To find the velocity of the ball at this time, we plug t = -0.5 into the velocity function we found in part

(a):v = -4t + 1

= -4(-0.5) + 1

= 3 m/s

Therefore, the velocity of the ball at the time it hits the ground is 3 m/s.
