Rutherford's Gold foil experiment involved the firing of atoms at a piece of gold foil only a few atoms thick. Rutherford expected that the particles would go straight through, but some were deflected. This experiment proved that atoms have a dense positively charged nucleus.

Answer: d. They showed that atoms have a dense nucleus.

Answer:

d) They showed that atoms have a dense nucleus.

Explanation:

Thomson's  model  predicted that the atom is composed of negatively charged electrons, which is surrounded by positively charged cloud. This was called Plum pudding model of the atom.

But Rutherford proved it to be incorrect . His gold foil experiment showed that the atom's central part is heavy and positively charged. The deflections of the alpha particles showed that the heavy central region is surrounded by negatively charged particles called electrons.

You are using a constant force to speed up a toy car from an initial speed of 6.5 m/s
Pachacha [2.7K]

By the work-energy theorem, the total work done on the car is equal to the change in its kinetic energy:

<em>W</em> = ∆<em>K</em>

<em>W</em> = 1/2 (0.34 kg) (22.9 m/s)² - 1/2 (0.34 kg) (6.5 m/s)²

<em>W</em> ≈ 82 J

Dear Sir,

           APPRECIATION FOR THE ADMISSION OFFER IN YOUR SCHOOL

          I humbly write this letter to express my sincere appreciation for the offer of admission in your highly esteemed institution of learning. The admission letter states that I was admitted to pursue a programme in Computer Science and this is a source of great delight for me. The opportunity is a unique one because I stand a great chance of acquiring deeper knowledge of programming software that will prove invaluable to me in my future career.  

         Over the years, I have been particularly thrilled with all the inventions that have been made possible with information technology and programming of many useful software. These inventions have made life a lot easier, hence my interest in getting the required knowledge that will enable me to contribute my quota to the society.

         This programme will also afford me the opportunity to relate with seasoned professionals in the field of Information Technology. When in contact with these professionals, I hope to ask them several questions on programming, the technicalities involved in it, and what is obtainable in the real-world scenario. Armed with these pieces of information, I believe that the programme will shape me to be an excellent professional that will be useful to the society.

         Once again, thank you for this very special opportunity. I hope to fully maximize the privilege.

Yours Sincerely,
