If the ball leaves his foot from a height of 4 ft write an equation for the vertical height s (in ft) of the ball t seconds after being kicked?
The answer depends on the direction (upward, horizontal, or downward) in which the ball leaves his foot.
What is the relationship between convection and plate techines?
I'm not familiar with the term 'techines' but I assume it's another word for tectonic plates (i.e. the Earth's crust). In the Earth's core there is a lot of heat produced from the molten iron (magma) of nuclear reactions. As we all know, heat rises. This creates an upward push, forcing the magma to underneath the Earth's crust. The magma then cools as it reaches the top (away from the nuclear reactive core) so then comes down in a circular motion, this circular convection creates a current heading in a certain direction - pushing the tectonic plates in that same direction. This is how plate tectonics are effected by convection currents.

What is the direction of the magnetic field if the current is directed upward or downward?
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
What is a downward flowing air current?
A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
How do you know that a force is negative or positive in relation to magnetic field?
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.
What is the magetic south pole?
Because the Earth wobbles on its path through the universe, the magnetic South Pole indicates the place on the planet where the geo-magnetic field lines are directed vertically upward.
If a wire had a current which was continually reversing directions and hten was placed between the poles of a magnet what would happen to the force on the wire?
Draw an imaginary line between the poles of a horseshoe magnet, say horizontal. If the wire is along that line there will be no magnetic force on it because the current would be parallel /antiparallel to the magnetic field. If the wire is perpendicular to the line, say vertical, the magnetic force on the wire will be in then out. If the wire is perpendicular ,say in/out, then the magnetic force will be vertical up then down. That's what the magnetic force would be, It changes direction when the current changes direction. To actually see the effect however could be difficult because; the wire has to be part of a circuit which could cause problems giving it enough "freedom" to move. If you use household current, which changes direction every 1/120 th of a second, the wire will not have time to move very far before the force changes directions and its doubtful you will be able to see the motion. Finally even if the current changed more slowly you still need a pretty strong current (a few amps) and a pretty strong magnet to see the effect.
Which direction does up thrust act in?
upward direction
What is an upward moving current of air?
An upward moving current of air is called an updraft.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
What direction do convection currents move?
Warmer material in a convection current rises upwards.
Is Upward an Adverb?
Yes, upward is an adverb. It means in a vertical direction.
Is stems growing upward positive or negative?
An upward direction is usually considered positive.
