A ball is thrown vertically upwards. It lands on the top of a cliff after attaining a maximum height of m in 7 s. What is the height of the cliff if the ball reaches the top of the cliff after 9 s? Use the three kinematics equations located here. Hint: The initial velocity will be zero, time will be 2 seconds, acceleration will be the gravitational acceleration and s will be the distance travelled.
Please refer to this post: Acceleration O Level. In particular, pay close attention to the kinematics equations. If you require more help, you can post on the forum. There are two methods to solving this question: 1 Use one of the kinematics equations; or 2 Plot out the velocity-time graph of the object. Refer to Reading Kinematics Graphs.Rogue season 4 download
Please check and correct if any mistakes. Thank you! This is wrong. The question asked to find the distance but you found acceleration instead. We can use the basic one of the four equations of motion. The answer is correct but you will have to take note of the presentation of the equation.

It should be:. More information in this post. What is the time taken for the acceleration? For Qn: 5. This is a distance-time graph of a moving car not drawn to scale. How can the distance decrease in the graph?The slope of the line is calculated by dividing the change in distance by the change in time for that time interval. Velocity is a physical vector quantity, both magnitude and direction are needed to define it. The instantaneous speed of an object is defined as the speed of the object at any given instant.
The instantaneous speed of an object can be determined by determining the average speed over a short distance and short timeand using this approximation as the instantaneous speed. An object travels 20 m in 5 sec and then another 40 m in 5 sec. What is the average speed of the object?

Here are some practical tips to help you bake better gluten-free bread. Yeast loves a warm environment and bread will rise more quickly and completely when ingredients are at room temperature rather than cold.Graduatoria imat 2020 nominale
Gluten-free flours are often stored in the refrigerator or freezer. Using chilled ingredients will significantly slow the yeasts' ability to leaven bread. A convenient way to bring chilled flours to room temperature is to measure flour(s) for your recipe and place in a bowl on the counter the night before baking. For perishable ingredients, like eggs and milk, set on the counter about 2 hours before preparing your recipe. Just like bread made with wheat, high protein content in gluten-free flour adds structure and flavor.
Sorghum, millet, amaranth, teff, gluten-free oatmeal, and buckwheat all contain more protein than rice flour. This may sound like a trivial subject, but there is a right way and a wrong way to measure flours. How you measure your gluten-free flours and starches can affect your gluten-free cooking results, for better or for worse. Step by Step Guide - How to Measure Gluten-Free Flour the Right WayEggs are natural leaveners that help boost the rise and volume of bread.
Eggs also add moisture, flavor, and protein to gluten-free bread recipes.UFC Fight Night 121 predictions by Luca Fury. UFC Fight Night 120 predictions by Luca Fury. UFC 217 predictions by Luca Fury.

Looking ahead, even one year, can be very tricky. Last year we predicted EVs and PHEVs in China to continue their boom. Pure electric car sales were the bulk of that volume with 208. We also predicted two disappointments for 2016: DS and Volkswagen.
VW has launched 3 new nameplates in 2016: the Sportsvan has outsold its rival BMW 2-Series by almost 3-to-1, the Phideon is more of an image booster than a volume model at 800 monthly sales, but the C-Trek is the most promising with 5. The American SUV brand could easily have been mentioned among our success stories of 2016, as it has sold well over 100. That puts the brand ahead of Cadillac, which did get a mention as one of the most successful brands in China last year.
But the reason for holding off and predicting even more success for Jeep in 2017 is the launch of the new generation Compass early this year. The previous generation Compass (and Patriot) have been the best selling import models in China, and starting local production will only add to that success.
Absolutely, but not irrealistic. In its home market, Geely wants Volvo to become a full-blown rival to the German luxury brands Audi, BMW and Mercedes-Benz, but it has a long way to go in terms of volume.We predict marketers will fight back with genuine improvements for consumers. More confident that UX basics will be addressed, publishers will be proactive in trying to win the hearts, minds and screen space of consumers.
Marketing campaigns will focus both on deterring new ad blocking users and discouraging existing users. The ethics of ad blocking will also be questioned as software providers increasingly attempt to profit from ad authorisation. Meanwhile, the technical ping-pong against ad blockers will continue. This will return short-term dollars to publishers but will override consumer wishes, so the safer long-term strategy will be to address the core concerns which have drawn people to ad blocking.
Expect to see the digital advertising industry urgently responding to these specific challenges throughout the coming year. In a media landscape of ongoing dramatic change, advertisers will more aggressively adopt multiple media alternatives to reach and connect with their audiences throughout 2017.
Synergies will become more important than any single channel and the collective weight of all channels put together. Marketers will be focused on understanding the role each media plays within a broader plan and how they rub off to produce synergistic effects.
The concept of synergies has been around for some time but what has changed is the planning aspect and the application of a discipline to the selection of channels to maximise its impact.
These numbers are not only growing but increasingly we are seeing non-TV synergies emerging as advertisers and agencies start to get their heads around this. But they offer opportunities for forming different kinds of relationships that meet consumer needs at different times and occasions.
Optimising media duplication and phasing can go a long way in driving synergies but as a first step, marketers will need to ensure that every medium has a role to play within the broader media mix. At the top of the marketing to do list will be gaining a rapid understanding of the needs, aspirations and behaviours of Generation Z, also referred to as the post-millennials and centennials. Brands will re-think their digital presence to emphasise co-creation, authenticity and transparency essential for connecting with Generation Z Brands will step up efforts to reach the emerging Gen Z consumer segment in 2017.
Marketers should invest in digital platforms to offer Gen Z consumers opportunities to interact and co-create. Transparency and imagination will be important as well as experimentation with augmented reality and virtual reality marketing to reach this highly imaginative and visual audience. Joline McGoldrick is Vice President of Insights and Product Marketing for the Media and Digital Practice of Kantar Millward Brown.
In 2017, successful brand stories will be built on delivering a consistent experience across touchpoints, and less on the number of touchpoints used. Michael Nicholas leads the Global Connected Solutions team at Kantar TNS, where he advises clients on digital and integrated marketing activities. Download PDF Content marketing: a new wave of experimentation Content marketing in 2017 will continue to gain traction at a fast pace.
New creative and media possibilities, particularly on mobile, will drive innovation and experimentation in both content and formats as marketers look to provide consumers with content that is useful, entertaining, or both.
Marketers will have to put away some money for experimentation with and creation of new content that will appeal to the imagination. Technologies like 360 Video, Augmented Reality (AR) and Virtual Reality (VR) will be used to develop immersive formats and stronger visual imagery. The focus will be on driving brand effectiveness with critical behavioral and demographic components. The future of programmatic targeting: blending brand affinity with behaviorIn markets where the right data platforms exist, marketers should explore how to integrate brand affinity data into their media buying, beyond just behavior.
Download PDF Galvanised by fear, the online advertising industry will more aggressively respond to ad blockers In 2017, the online ad industry will turn a corner by adopting better ad formats and proactively persuading audiences not to block ads.
Advertisers need to create more compelling content which will be relevant in the contexts where it is placed. Publishers need to reduce advertising clutter, and focus on polite, user-responsive formats.

The itinerary and road map provided by Nordic Visitor were perfect. Things to see along the way were clearly marked. Distances between accommodations were perfect, getting us in to each place at a reasonable hour without too much driving time.
Iceland is a beautiful country, and considering the time we had to spend there, Nordic's itinerary helped optimize the experience. It also gave us a good sense for what else we would like to see and do when we visit again. Thanks to Nordic Visitor for doing all the hard work, the planning, arranging of transportation and accommodations, and for routing us through wonderful towns and scenery.
Your hard work made our visit all the more enjoyable and safe. We could have spent much more than that, but this was our experience without feeling we had to be too thrifty. I really wouldn't change a thing for this visit. Our son works in Iceland and we shared this adventure with him. For all of us, this was a great adventure and the best possible way to see some of Iceland in a short period of time, and at a reasonable expense.
We are extremely happy with the Express Iceland package that Nordic Visitor prepared for us. We did find that we had to keep a tight schedule in order to visit all of the recommended destinations in the day-to-day itineraries, but that is probably the nature of the express tour.Manodopera significato treccani
That said, Solveig did a great job preparing our itinerary (as well as marking our map), and all of the recommended destinations we visited were absolutely wonderful. Our only regret is that we couldn't stay in Iceland longer. We can't wait to visit again, and we will surely be using Nordic Visitor again.
Additionally, we will happily recommend Nordic Visitor to our family, friends, and coworkers who are interested in visiting Iceland. The accommodations were excellent and so nice not to have to look for a hotel. The food for breakfast was such a variety and very good.
