A ball is thrown vertically upward and it reaches a height of 90 m . Find (a) the velocity with which it was thrown and (b) the height reached by the ball 7 seconds after it was thrown (g=9.8 ms-2) |
|
Answer» Given:-
To Find:-
Solution:-By using 3rd EQUATION of motion → v² = u² +2as Substitute the value we get → 0² = u² + 2×(-9.8) ×90 → 0 = u² + (-1764) → -u² = -1764 → u² = 1762 → u = √1764 → u = 42m/s ∴ The initial velocity of the ball is 42m/s . Now we have to calculating the height attained by ball in 7 s. Using 2nd equation of motion → h = ut +1/2at² Substitute the value we get → h = 42×7 + 1/2×(-9.8)×7² → h = 294 + (-4.9) ×49 → h = 294 - 240.1 → h = 53.9 m ∴ The height attained by the ball aftern 7 second is 53.9 metre. |

Discuss the role of physics in the field of medicine and its applications with invention |
|
Answer» er:1) USING PARTICLE ACCELERATORS TO DEFEAT CANCER In the last 50 years, medical physicists have spearheaded the development and application of particle accelerators for cancer treatment. Once confined only to physics laboratories, linear accelerators are sophisticated HIGH energy machines that can now deliver BEAMS of energetic ELECTRONS or X rays to malignant tumors -- at doses capable of killing cancerous cells and STOPPING the tumor's growth. In recent years, an advanced treatment technique called intensity-modulated radiation therapy (IMRT) has enhanced the ability of radiation to control tumors. IMRT uses computer programs to precisely shape the treatment field and control the accelerator beam in order to deliver a maximal dose of radiation to a tumor while minimizing the doses to surrounding healthy tissues. IMRT is already in USE for treating prostate cancer, cancers of the brain, head and neck and other malignant diseases, in children and in adults. Explanation: |

The difference between AC and DC is that direct current |
|
Answer» ong>Answer: DIRECT current (DC) is the flow of electric charge in only one direction. Itis the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that PERIODICALLY reverses direction. The computer can utilise the DC current, but mostly currents are AC. A power SUPPLY unit changes the current from AC to DC. hope this helps you mate..! |
