Q: 2. The acceleration due to gravity on Earth a. is the same at all locations on t

Q2 option (e) is correct as it varies with least on equator and most on poles Q3 The direction of plane is not shown in the figure .It is missing ,may be picture is not taken properly Q4 option (c) is correct as centripetal is toward center Q5 option (a) is correct as v=sqrt(GM/r)=>r=GM/v^2 Q6 option (e) is correct

2. The acceleration due to gravity on Earth a. is the same at all locations on the surface of Earth b. is greater for heavier objects is greater at the equator and less at the poles d. c. is the same at any two locations provided that the distance to the centre of Earth at those locations is the same e. varies slightly with latitude 3. A plane must fly to a destination that is south-west of its departure point. Because of the wind, it heads What direction is the wind blowing in? a. south b. west c. north-east d. north-west e. east 4. For an object travelling with "uniform circular motion," its acceleration is a. zero because the speed is constant directed tangent to the circle directed toward the centre of the circle changing in magnitude depending on its position in the circle directed outward from the centre of the circle b. c. d. e. The orbital radius of a satellite circling the Earth a. b. c. d. e. 5. depends only on its orbital speed depends only on its mass depends on both its orbital speed and its mass is the same for all satellites is directly proportional to its orbital speed 6. Astronauts on board an orbiting space station appear to be "loating" because a. b. c. d. e. they are in the vacuum of space they are outside Earth's gravitational influence the force of gravity acting on them has been reduced to an insignificant level they have become truly "weightless" they are in free fall along with the space station itself

Explanation / Answer

option (e) is correct as it varies with least on equator and most on poles

The direction of plane is not shown in the figure .It is missing ,may be picture is not taken properly

option (c) is correct as centripetal is toward center

option (a) is correct as

v=sqrt(GM/r)=>r=GM/v^2

option (e) is correct
