medwhite0: 6000J of heat Is delivered to 10g of dry ice at 0°C. What is the final temperature if the container has a heat capacity of 20J/K? c of water = 4200J/kg/K, latent heat of fusion of ice = 3.33 x 10^5J/kg.
2. Marketers: The advertising tools of the internet can allow brands to fashion their messages to customers with 'precision accuracy'. pointing to new experiments with technologies that study customer behaviour to identify what kind of ads will be most effective, Webb indicated that if those tools work, then it would be translated to smaller Marketing and Ad firms.
3. Customer service: New technologies like predictive analytics could kill most of these jobs. Robots like Cortana and Watson fit perfectly for such jobs.
4. Factory workers: Haptics, a sensor based technology allows people to virtually feel objects that are far away. Now imagine such A.I. incorporated into a manufacturing department? it would be more cheaper and efficient.
5. Journalists: The internet has made buying and reading a local newspaper 'Old Fashioned'. With a new technology of 'Robot Journalists' which uses algorithms to automatically create stories and upload them on websites without human interaction, more journalism position would be wiped out.
6. Lawyers: Mrs Webb believes that non-litigation lawyers could soon be replaced by online form-based services that carry out simple tasks like trademark applications, Wills and even Divorce. Its been made easier by the demand to make records more open and easily accessible, thereby reducing the need for high-priced lawyers.

The future is unevenly distributed in favor of the United Arab Emirates. Recently, two men donned jetpacks and flew into the night air above Dubai. Yves “Jetman” Rossi previously flew over the Emirati desert in his custom-built wing with jets, but for this paired flight, he was joined by Vince Reffet, a skydiver who once base jumped off the Burj Khalifa. According to a statement accompanying a video release of the flight, the pair fly over the “Burj Khalifa, The Palm Jumeirah, and the Liwa desert.” Their flight together was teased at the end of Jetman’s last video.
since the half-life is every 12hrs that means the mass disintegrates into 2 , two times a day in 2 days which is 48hrs it would have been halved 4 times. so divide the mass by 2 four times and u get 3.125g
wait o, yea i saw it buh i didn't say anifin cuz robibhez is yt to say if u ryt n workings...na wetin go ginger us b dat.
