Istanbul is a transcontinental city in Eurasia, straddling the Bosporus strait (which separates Europe and Asia) between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives in suburbs on the Asian side of the Bosporus.
v1 = 6m/s
v2 = 0
∆v = v1 - v2 = 6m\s
s = t * v = 15m
t = s\v1 = 15(m) \ 6(m\s) = 2.5s
a = ∆v\t = 6(m\s) \ 2.5s = 2.4m\s2
a = F\m = 2.4m\s2
F = a * m = 2.4m\s2 * ?kg
I can't tell you this because I don't know the mass of this cyclist
Answer:
0.232 mm.
Explanation:
Power, P = 96 W
Voltage, V = 120 V
Length of wire, l = 4.2 m
Let r be the radius of the wire.
Resistivity of nichrome, ρ = 1.5 x 10^-6 ohm metre
P = V^2 / R
R = 120 x 120 / 96 = 150 ohm
r = 1.16 x 10^-4 m
Diameter = 2 x r = 2 x 1.16 x 10^-4 = 2.32 x 10^-4 m = 0.232 mm
Thus, the diameter of the wire is 0.232 mm.
