PHY101 - Physics

It is true or wrong that Raise For Success an automobile at rest can be accelerating very fast?

Phy101: Similarities b/w light wave and sound waves. Three postulates of Bohr atomic theory. 3.who discovered nucleus? Write the steps with explanation. 4.longitudinal and transverse waves. What is the work done? If Force is 500N, height of downwards clif is 30m and angle with land is 30 degree. 6.diagram was given with no data you have to find tention. 7.a) Gravitational force of sun is greater than Earth then why moon is not pulled away by the Sun in lunar eclipse. b) satellite is moving in the orbit as there is vaccum, and satellite is moving on thin air. Is there any air resistance which slows down the satellite speed. Numerical. You find potential difference. Force and work done.
