A 0.50 kg croquet ball is initially at rest on the grass. When theball is struck by a mallet, the average force exerted on it is240 N. If the ball's speed after beingstruck is 3.0 m/s, how long was the malletin contact with the ball?

Answer:

True

Explanation:

The Kurt Lewin Model: Defines change as a modification of the forces that maintain the behavior of a stable system.

    Which is the product of two types of forces that help to make the change (F. Drivers) and those that prevent change from occurring (F restrictive) that want to maintain the same state of the organization.

    When both forces are balanced, the levels of behavior are maintained and a quasi-stationary equilibrium is achieved according to Lewin. To modify it you can increase the forces that cause the change or decrease the forces that prevent it or change both tactics. Lewin proposes a three-phase plan to carry out the planned change

Defrosting: involves reducing the forces that keep the organization at its current level of behavior.

Change or movement: It consists of moving towards a new state or new level within the organization with respect to behavior patterns and habits, behaviors and attitudes.

Recongelación: The organization is stabilized in a new state of equilibrium where culture, norms, policies and organizational structure are used.

According to Lewin's Change Model, organizations must deliberately change old habits, learn new work methods, and accept them as part of the job. Hence the statement is True.

True. According to Lewin's Change Model, organizations must deliberately change old habits, learn new work methods, and accept them as part of the job. This process involves transitioning through phases of change to achieve successful organizational transformation.

A car sits on an entrance ramp to a freeway, waiting for a break in the traffic. Then the driver accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 24 m/s (54 mi/h) when it reaches the end of the 120-m-long ramp. The traffic on the freeway is moving at a constant speed of 24 m/s. What distance does the traffic travel while the car is moving the length of the ramp?

Answer:

Distance traveled=240 m

Explanation:

Given data

Initial velocity of car v₀=0 m/s

Final velocity of car vf=24 m/s

Distance traveled by car S=120 m

To find

Distance does the traffic travel

Solution

To find the distance first we need to find time, for time first we need acceleration

So

[tex](V_{f})^{2}=(V_{o})^{2}+2aS\\ So\\a=\frac{(V_{f})^{2}-(V_{o})^{2} }{2S}\\ a=\frac{(24m/s)^{2}-(0m/s)^{2} }{2(120)}\\a=2.4 m/s^{2}[/tex]

As we find acceleration.Now we need to find time

So

[tex]V_{f}=V_{i}+at\\t=\frac{V_{f}-V_{i}}{a}\\t=\frac{(24m/s)-(0m/s)}{(2.4m/s^{2} )}\\t=10s[/tex]

Now for distance

So

[tex]Distance=velocity*time\\Distance=(24m/s)*(10s)\\Distance=240m[/tex]

Answer: State laws take precedence over UETA

Explanation: The UETA is an attempt to standardize acceptance of electronic documents and signatures, but state laws govern the use of these electronic items.

UETA is a legislative act that, in terms of the statute of laws, accords electronic signatures the same legal standing as handwritten ones as released by the Uniform Law Commission in 1999.

Only specified types of electronic  transactions and those where the parties have consented to conduct the transaction electronically are covered by the UETA.

Any electronic sound, symbol, or procedure that is both attached to or linked with a document or contract qualifies as an electronic signature executed with the goal of signing the document.

Any electronic sound, symbol, or procedure connected to a contract with the intent to sign is considered an electronic signature. Even if an electronic signature is valid, a judge may rule that it cannot be used because the amount of assurance it provided was insufficient.

Every state  the district of Columbia, Puerto Rico, and the  Islands have accepted the UETA. Despite not having the UETA, New York has similar legislation that make electronic signatures enacted.

Answer:

1. Yes, BEVs or hydrogen fuel cell vehicles are a more promising transportation technology for the future.

2. Yes, car companies should be require to produce electric cars.

Explanation:

Both BEVs and FCEVs have their roles in the future of transportation, with BEVs currently leading in light-duty vehicles and FCEVs being more suitable for heavier-duty applications. Mandating the production of electric vehicles involves several considerations, including environmental benefits, technological adoption, and infrastructure readiness.

Comparing Battery Electric Vehicles (BEVs) and Hydrogen Fuel Cell Vehicles (FCEVs)

When looking at the future of transportation technology, both Battery Electric Vehicles (BEVs) and Hydrogen Fuel Cell Vehicles (FCEVs) have their respective advantages and roles to play. BEVs are currently more prevalent and benefit from ongoing advances in battery technology that aim to increase energy density, decrease charging time, and reduce weight, securing their place in the market, especially for short to medium-range transportation. Meanwhile, FCEVs offer promise for applications where the quick refueling and longer range of conventional vehicles are required, making them particularly suitable for medium-duty and heavy-duty vehicles, such as delivery trucks and buses. The choice between the two technologies might depend on the specific needs of the transportation sector, whether it's for personal vehicles, long-distance road transport, or heavy-duty applications.

Should Car Companies Be Required to Produce Electric Cars?

The requirement for car companies to produce electric cars stems from global environmental pressures such as climate change and air quality concerns. Governments might consider mandates for electric vehicles production to reduce greenhouse gas emissions and promote fuel independence. However, the question involves not only environmental and political considerations but also practical aspects of technology adoption, economics, and consumer preferences. The impact on residential areas in terms of increased electrical demand, potential reliance on nighttime charging to utilize solar input, and consumer willingness to adopt new technologies while considering the costs of battery decline and replacement are all factors that would need to be addressed in such a transition.

Answer:

Explanation:

momentum (p) = mass × velocity.

Change in momentum (∆p) = final momentum - initial momentum.

∆p = 0.045×38 - 0.045×0

∆p = 1.7 kg m/s.

Momentum (p) = mass × velocity. Change in momentum (∆p) = final momentum - initial momentum.

The word "momentum" is frequently used in sports. A squad that is moving forward and has momentum will be difficult to stop.

A team that is genuinely moving forward and gaining momentum will be challenging to stop. A physics phrase, momentum describes the amount of motion that an item has. The momentum belongs to a sports team that is actively playing.

The definition of momentum is "mass in motion." Since every item has mass, if it is moving, it must have momentum because its mass is in motion.  ∆p = 0.045×38 - 0.045×0, ∆p = 1.7 kg m/s.

Therefore, Momentum (p) = mass × velocity. Change in momentum (∆p) = final momentum - initial momentum.
