Depends on the mass of the projectile versus the object.

The force of gravity is dependent upon the mass of the object.  Therefore if the mass of the projectile and the mass of the object are exactly the same than both objects will fall at the same rate and will collide.  If the mass of the object is significantly larger than it will fall faster and the projectile will pass above it.  The opposite is true if the mass of the object is less than the mass of the projectile, in which case the projectile will pass underneath.

Lastly, this analysis excludes the force of wind resistance on the projectile and the object.  Under a complex model how the projectile travels through the air will have a separate impact that will alter its decent or rise outside of gravity.  For example, if the projectile is spinning it could "cut" into the wind and cause accelerated drop.  Think of a curve ball in baseball or a rising fastball.

Strength of the magnetic field: C) 20 T

Explanation:

When a conductive wire moves in a region with magnetic field, an electromotive force is induced in the wire due to the phenomenon of electromagnetic induction.

If the wire moves perpendicular to the field, the magnitude of the induced emf in the wire is given by

\epsilon=BLv

where

B is the strength of the magnetic field

L is the length of the wire

v is the speed of the wire

For the wire in this problem, we have:

\epsilon=12 V is the emf induced in the wire

v = 3.0 m/s is the speed of the wire

L = 0.20 m is its length

Solving for B, we find the strength of the magnetic field:

B=\frac{\epsilon}{Lv}=\frac{12}{(0.20)(3.0)}=20 T

A very long straight wire has charge per unit length 1.44×10-10C/m.
4vir4ik [10]

Answer:

Distance of the point where electric filed is 2.45 N/C is 1.06 m            

Explanation:

We have given charge per unit length, that is liner charge density \lambda =1.44\times 10^{-10}C/m

Electric field E = 2.45 N/C

We have to find the distance at which electric field is 2.45 N/C

We know that electric field due to linear charge is equal to

E=\frac{\lambda }{2\pi \epsilon _0r}, here \lambda is linear charge density and r is distance of the point where we have to find the electric field

So 2.45=\frac{1.44\times 10^{-10} }{2\times 3.14\times 8.85\times 10^{-12}\times r}

r = 1.06 m

So distance of the point where electric filed is 2.45 N/C is 1.06 m
