An object that is thrown vertically upward will return to its original position with the same speed as it had initially if air resistance is negligible if air resistance is appreciable?
As an object rises WITH air resistance, the acceleration is larger in size than g, because both gravity and air resistance will be causing a downward acceleration. As the object FALLS with air resistance, the acceleration will be smaller in size than g, because gravity and resistance will be opposing each other. Because of the smaller acceleration being applied over the same distance, the return speed will be slower than the launch speed.
A 2kg is dropper from a height of 1000m what is the force of air resistance on the obhect when it raches terminal velocity?
When it reaches terminal velocity it is not accelerating. According to newton's 2nd law, if acceleration = 0, then Net force = 0 If we call up to be positive direction Net force = -mg + Force air resistance = 0 So the air resistance force would be equal in magnitude to m*g and opposite in direction. m is mass of object, g is about 9.81 for objects near earths surface

G force
What is the skydiver's downward velocity after 2 seconds?
Assuming we neglect air resistance and start from rest in the vertical plane - use v=u+at so v = 0+(10x2) assuming g = 10N/kg =20m/s In practice it will be less because air resistance will tend to slow the skydiver down.
What is the upward force of air against a moving object?
= the (square of the velocity (m/s) * drag coefficient ) newtons if terminal velocity is known (forces balanced , no further acceleration), drag coefficient can be found. say terminal velocity(tv) = 70 m/s, acceleration due to gravity(g) = 9.8 m/s^2, mass(m) = 80kg m * g (force down) = tv^2 * drag coefficient (force up) at terminal velocity then m * g / tv^2 = drag coefficient 80 * 9.8/4 900 = 0.16

If a projectile is shot in the air neglecting air resistance what is its vertical accelrration?
the vertical accelaration in case of a projectile is 'g'.

What is the difference between absolute and specific humidity?
Relative humidity is a ratio of the actual water vapor content of the air to the amount of water vapor needed to reach saturation. Absolute humidity is the mass of water vapor contained in a given volume of air.
