Answer:
d = 1600 m
Explanation:
If car start from rest and accelerates uniformly then the displacement of the car is given as
now we know
now if the same car will accelerate from rest for four times of the previous time interval
then we will have
so the distance will be 16 times more
Answer:
= 8.33 Watt
Explanation:
where,
p = resistivity
l = length
A = cross section area
Given that ,
p = resistivity = 6.0 × 10–8 Ω
l = 2m
A = cross section area = 2.0 mm × 2.0 mm = 4 x 10^-6 m^2
A = 2 x 2 mm^2 = 4 x 10^-6 m^2
p = 6 x 10^-8 ohm metre,
V = 0.5 V
Let R be the resistance of the rod
R = 3 × 10⁻²Ω
Heat generated = V^2 / R
= (0.5)^2 / (3 x 10^-2)
= 8.33 Watt
