Compute the orbital periods and angular velocity of a satellute revolving around the earth at altitude of 270km.(given: radius of earth R=6000km and g=9.83m/s^2.)

An atom that has fewer electrons that protons is called a positive ion.

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

The magnets are probably damaged or there not strong enough to attached to the refrigerator

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
