Fizik Ödev Yardımı
Fizik, tüm doğa bilimleri arasında çok önemli bir konudur, yaşamın harikalarını açıklamak için kullanılır ve aynı zamanda çalışılması en zor konulardan biridir.
QuestionAI, etkileşim halindeki kuvvetler altındaki moleküllerin eşlik eden yörüngeleri ile her bir atom ve onun özellikleri hakkında bilgi edinebileceğiniz, fiziğe yeni başlayanlar için zengin ve kolay bir fizik problemi çözücüdür. Elbette galaksiler arasında saklı sırları diğer fizik meraklılarıyla da keşfedebilirsiniz. Tahminlerinizi ve sorularınızı yapay zekaya cesurca yöneltin; kolayca güvenilir yanıtlar bulacaksınız.
- 8. Which pulls harder gravitationally, the E arth on the Moon, or the Moon on the Earth? Which accelerates more? (a) The Earth on the Moon; the Earth. (b) The Earth on the Moon; the Moon. (c) The Moon on the Earth; the Earth. (d) The Moon on the Earth; the Moon. (e) Both the same ; the Earth. (f) Both the same ; the Moon.
- 9.In the International Space Station which orbits Earth, astronauts experience apparent weightlessness because (a) the station is so far away from the center of the Earth. (b) the station is kept in orbit by a centrifugal force that counteracts the Earth's gravity. (c) the astronauts and the station are in free fall towards the center of the Earth. (d) there is no gravity in space. (e) the station's high speed nullifies the effects of gravity.
- 10. Two satellites orbit the Earth in circular orbits of the same radius.One satellite is twice as massive as the other. Which statement is true about the speeds of these satellites? (a) The heavier satellite moves twice as fast as the lighter one. (b) The two satellites have the same speed. (c) The lighter satellite moves twice as fast as the heavier one. (d) The ratio of their speeds depends on the orbital radius.
- (II) What is the maximum speed with which a 1200 -kg car can round a turn of radius 90.0 m on a flat road if the coefficient of friction between tires and road is 0.65 ? Is this result independ ent of the mass of the car?
- (III) A particle revolves in a horizontal circle of radius 1.95 m. At a particular instant, its acceleration is 1.05m/s^2 in a direction that makes an angle of 25.0^circ to its direction of motion . Determine its speed (a) at this moment, and (b) 2.00 s later ,assumin g constant tangential acceleration.
