A large box, placed on the ground, has to be shifted up to a wall, as shown in the given figure. Three boys push the box together. They have to apply a large amount of force to move the box. The motion of the box is opposed by the frictional force between the box and the ground. If wheels were present below the box, then they would have to apply

If the coefficient of x^(2) and the constant term have the same sign and if the coefficient of x term is zero, then the quadratic equation has no real roots. State true or false and justify your answer.

You are pushing a wooden crate across the floor at a constant speed. You decide to change the orientation of crate such that area of contanct with floor becomes half. In the new orientation, to push the same crate across the same floor with the same constant speed, the force that you apply must be about__________ as the force required before you changed the crate's orientation.
