Answer:

A. It will increase

Explanation:

Area of a wire is:

R = ρL/A

where ρ is the resistivity of the wire,

L is the length of the wire,

and A is the cross-sectional area.

If A decreases, while ρ and L stay the same, then R will increase.

Flura [38]

Answer:

Explanation:

a ) wave length of waves in water

= velocity / frequency

= 1482 / (18 x 1000)

= .0823 m

= 8.23 cm

b ) Applying Doppler's effect relation

frequency of reflected wave

= 18000 [ 1482 / (1482 - 4.95 ) ]

= 18000 x 1.003385

= 18061

Difference in frequency= 61 Hz
