A bicycle with a 15 kg mass is easily stopped when a force of 60 N is applied. How much force would be needed to stop the bicycle if the time allowed to stop the bike was doubled?

Answers

Answer:

Going downhill at a steady speed, the forces along the direction of motion are:

net force = m * a = 0

W * sin(7) - Fdrag = 0

so Fdrag = m * g * sin(7) where m=62.kg and g=9.8m/sec^2

Explanation:

3.1. A stone of mass 2kg is thrown vertically upward with a speed
of 20m's Calculate the maximum height reached.​

Answers

Answer:

20.41 m

Explanation:

Let's list out the relevant variables in this problem. Take the upwards direction to be positive and the downwards to be negative.

v₀ = 20 m/sv = 0 m/sa = -9.8 m/s² Δy = ?

We are using the fact that at maximum height, the object's velocity is 0 m/s right before it changes direction to fall vertically back down to Earth.

Find the constant acceleration equation that contains these four variables.

v² = v₀² + 2aΔy

Substitute the known values into the equation and solve for Δy, the maximum height.

(0)² = (20)² + 2(-9.8)Δy 0 = 400 - 19.6Δy -400 = -19.6Δy Δy = 20.4081632653

The maximum height of the stone is 20.41 m. Notice that its mass was irrelevant when solving for its maximum height when thrown.

The mass of an Apple, m = 100 g = 0.1 kg

It fell from 2 metres high tree.

We need to find the work done by it. The work done is given by :

[tex]W=mgh\\\\W=0.1\times 9.8\times 2\\W=1.96\ J[/tex]

So, the required work done is 1.96 J.

Provide two examples of how health care workers can demonstrate their commitment to quality control through their personal appearance.

Answers

Standards of Performance can be used in numerous ways to help select applicants who are well suited to the healthcare organization’s culture. As we look at best practices for using healthcare standards of performance, we will share some specific examples. This week we examine standards for attitude and appearance.

Attitude:

Our job is to serve our customers and provide high quality service with care and courtesy.
Always thank customers for choosing our organization.
Exceed expectations.
Acknowledge a customer’s presence immediately. Smile and introduce yourself at once.
Attitude takes into account three things: our body language, our friendliness and our willingness to connect with our customers.

The body language that goes along with the words that we are speaking greatly influences how we are understood. In fact, experts tell us that how we speak is just as important as what we are saying! Our customers are our reason for being in the healthcare environment; our attitude should always be one of concern, respect and genuine caring.

As a customer yourself, do you remember those places of business where the staff was friendly and went out of its way to acknowledge you? Of course you do, since this was an environment where you felt welcomed. We exhibit friendliness by smiling warmly, introducing ourselves immediately, and never, ever ignoring someone. All our customers are equally deserving of attention.

Finally, we show the right attitude by meeting the needs of our customers or finding someone who can. We go out of our way to be helpful; for example, we don’t point the way – we accompany the customer to where they need to go. In addition, we always thank them for choosing us to provide their healthcare experience.

An attitude of service excellence is further exhibited by showing interest when a customer speaks to us. Each one, without exception, should be treated as if he or she is the most important person in our facility; and rudeness is never acceptable. We are attentive to the customer’s immediate need, or gladly take the individual to someone better equipped to provide the service. We always apologize for problems and inconveniences, and enthusiastically carry out service recovery.

Lastly, we recognize that our customers have a sense of urgency and show them that we value their time. Customers are not an interruption of our work; they are our focal point, and caring for them with an attitude that shows we value them should be our daily goal.

Appearance:

Be clean and professional.
Follow dress code policies and wear your identification badge correctly at all times.
Pick up litter and dispose of it properly.
Clean up spills and return equipment to its proper place.
How long does it take to make a first impression on a customer? Just seven seconds, according to popular research. How our customers perceive us in that brief time is very important because it sets the stage for their entire healthcare experience. A first impression is sometimes referred to a “moment of truth” because customers believe that what they are hearing, seeing or feeling is reality – that is, the truth of the situation. No matter that their first impression is merely a snapshot of less than one moment in time. It is perceived as genuine: who we are, the quality of service that we deliver, or our physical environment of care. Needless to say, making that first impression a good one is crucial.

Moments of truth are directly impacted by the appearance of staff as well as that of the workplace, both of which are a direct representation of our organization. When we dress appropriately for the job and wear our name badges so that they are easily readable, we project professionalism to our customers. We not only create a good first impression, but we also reinforce our culture of quality through attention to personal appearance. The same principle applies to our healthcare setting. When we take pains to keep our workspace uncluttered and to pick up trash in hallways and public areas, we are sending a positive message to those who enter the doors of our facility for the first time. We should always take pride in how we present ourselves and in the facility itself. Doing so conveys respect for customers and their expectations.

Shrill sound is of -------------- *

Higher frequency
Lower frequency
Higher amplitude
Lower amplitude

Answers

Answer:

Higher frequency.

Explanation:

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases. A student could verify this statement by measuring the time required for sound to travel a set distance through a solid, a liquid, and a gas.

Mathematically, the speed of a sound is given by the formula:

[tex] Speed = wavelength * frequency [/tex]

Generally, the frequency of a sound wave determines the pitch of the sound that would be heard.

A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.

Hence, shrill sound is of higher frequency.

6. What is the resultant force on each car below? Remember TWO pieces of
information are needed.
7. What additional statement could we make about each car? Think about what key
words we could use

Answers

Explanation:

In first case, the forces on LHS and on RHS is the same i.e. 3 N. The force acting on the car is balanced force. As a result, the car will not move at all.

In second case,

Force on RHS = 2000 N

Force on LHS = -6000 N

Net force acting on it is given by :

F = 2000+(-6000)

= -4000 N

Hence, this is the required solution.

You are in a car traveling at 20 m/s. An ambulance is behind you traveling 35 m/s in the same direction. What frequency do you hear if the siren has a frequency of 550 Hz?

Answers

Answer:

The frequency heard is 576.78 Hz

Explanation:

The Doppler effect is defined as the apparent frequency change of a wave produced by the relative movement of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.

This is what happens in the first part of this problem, where the sender is train A and the receiver is train B. They are both moving in opposite directions. In this case, where both are in motion, the frequency perceived by the receiver will increase when receiver and transmitter increase their separation distance and will decrease whenever the separation distance between them is reduced. The following expression is considered the general case of the Doppler effect:

[tex]f'=f*\frac{v+-vR}{v+-vE}[/tex]

Where:

f ', f: Frequency perceived by the receiver and frequency emitted by the issuer respectively. Its unit of measurement in the International System (S.I.) is the hertz (Hz), which is the inverse unit of the second (1 Hz = 1 s-1)

v: Velocity of propagation of the wave in the medium. It is constant and depends on the characteristics of the medium. In this case, the speed of sound in air is considered to be 343 m / s

vR, vE: Speed ​​of the receiver and the emitter respectively. Its unit of measure in the S.I. is the m / s

±, ∓:

We will use the + sign:

In the numerator if the receiver approaches the emitter In the denominator if the emitter moves away from the receiver

We will use the sign -:

In the numerator if the receiver moves away from the emitter In the denominator if the emitter approaches the receiver

In this case you are in a car traveling at 20 m/s and an ambulance is behind you traveling 35 m/s in the same direction.

In this case the receiver, you in the car, moves away from the emitter, while the emitter, the ambulance, approaches the receiver behind you in the same direction. So the frequency is calculated by the expression:

[tex]f'=f*\frac{v-vR}{v-vE}[/tex]

Being:

f= 550 Hzv=343 m/svR= 20 m/svE= 35 m/s

and replacing:

[tex]f'=550 Hz*\frac{343 m/s-20 m/s}{343 m/s-35 m/s}[/tex]

you get:

f'= 576.78 Hz

The frequency heard is 576.78 Hz

A wave with a frequency of 325 Hz. is travelling at a speed of 125 m/s. What is the wavelength of this wave?

Answers

Answer:

0.385 meters

Explanation:

Just remember this very simple equation:

velocity=(wavelength)*(frequency)

I always remember it as "Velma is Waving Frantically"

So, 125=(wavelength)*(325)

Therefore, wavelength=0.385 meters!
