Answer:
Time required by boat 1 for the round trip is less than that of boat 2.
Hence, boat 1 wins.
Explanation:
Case 1: Boat 1
Speed of boat =
time =
While going to another end
time =
time =
time = 1 hour
While going back,
time =
time =
time = 1 hour
Total time taken by boat 1 is,
Total time by boat 1 = 1 hour + 1 hour = 2 hour
Total time by boat 1 = 2 hour
Total time taken by boat 1 for the round trip is 2 hour.
Case 2: Boat 2
Speed of boat =
time =
While going to another end
time =
time =
time = 2 hour
While going back,
time =
time =
time = 0.66 hour
Total time taken by boat 2 is,
Total time by boat 1 = 2 hour + 0.66 hour
Total time by boat 1 = 2.66 hour
Total time taken by boat 2 for the round trip is 2.66 hour.
Time required by boat 1 for the round trip is less than that of boat 2.
Hence, boat 1 wins.

Answer:
c. 1.5 degrees C
Explanation:
Given that
Q= 240 J/s ( we know that J.s=W)
Q= 240 W
L= 2 x 10⁻3 m
A= 1.6 m²
K=0.20 J/(s•m•degrees C))
Lets take temperature difference is ΔT
We know that from Fourier law
Now by putting the all values
ΔT = 1.5 degrees C
c. 1.5 degrees C
