    mobile towers

    Can the mobile towers on building do any harm to the people living in it by radiation?
  2. What is the reason behind the twinkling of stars?Is it due to pollution or refraction of light?

    earth and moon

    Swansnot , the moon has a gravity of only 1 by 6th in comparison to the earth.So the earth should pull the moon.

    earth and moon

    As we all know that the earth has more attraction power than the moon.Then why don't the earth attracts the moon and moon collides with the earth?
  5. well if the building is tall enough then the gold one will hit first as friction will cause the aluminium one to stop accelerating at a slower velocity than the gold one. This was your answer. But the friction should be same for both as they are of same shape and size.Then they should fall at the same time.
  6. A question from gravity.If I take two things say gold and aluminium of same shape and size and fall it from a buliding , which will fall first or they will fall at the same type?And if I repeat the same activity in vaccum , what will happen?What matters in free fall?
