R = ρl/A
From the equation above R = Resistance, l = length, A = Cross Sectional Area of wire.
From the equation, it can be seen that R would increase if the wire's area is reduced.
If the area of the wire is reduced, means the same thing as:
<span>A. decreasing the wire’s thickness</span>
Answer:
a. Horizontal component v = 12 m/s
b. Magnitude of velocity v = 20.78 m / s
Explanation:
Vₓ = 12.0 m / s eastward
β = 30.0 °
So
a.
Vt = Vₐ - Vₓ
Vₐ = 0 i
Vt = 0i - 12.0 = - 12 m/s
b.
Vₙ = 12 / sin (30 °)
Vₙ = 24 m / s
Vₙ = 24 * con (30 °)
Vₙ = 20.78 m / s

Answer:hen a bird flies, its wings push in a down- ward and a backward direction. This pushes air downward and backward. By Newton's third law, the air pushes back on the bird in the opposite directions—upward and forward. This force keeps a bird in the air and propels it forward.
