When you urinate, you increase pressure in your bladder to produce the flow. For an elephant, gravity does the work. An elephant

Answer and Explanation:

currents i = 2.9 A

           i ' = 4.4 A

The magnitude (in T.m) of the path integral of B.dl around the window frame is calculated as = μo * the enclosed current

          = μo* ( i ' - i )

According to Ampere's law

where μo = permeability of free space = 4π * 10 ^-7 H/m

Substituting the values gives us the magnitude (in T.m) of the path integral of B.dl = (4π*10^-7)(2.9+4.4)

                                 = 1.884 * 10^-6 Tm

Ans    specifically, 4

Explanation:

Answer:

v' = -18 m/s

Explanation:

• Assuming no external forces act during the collision, the overall momentum must be preserved as follows:

• The initial momentum can be defined this way (with the initial direction of the ball considered positive):

• The final momentum can be formulated as follows (given that v'b moves in the opposite direction to vb):

• If we consider that Mc >> mb, we assume the car's speed remains unchanged as a result of the collision, allowing us to substitute V'c for Vc in (3).
• Consequently, we can rewrite (3) like this:

• By substituting (2) and (4) back into (1), we arrive at:

• By simplifying and rearranging, we can solve for v'b like this:
• , which makes sense because it's as though the ball collided with a wall and simply reversed its velocity post-collision.
