Answer:
Option (D)
Explanation:
n = 0.35,
Temperature of hot reservoir,
T1 = 427 C = 700 K
Temperature of cold reservoir, T2 = ?
Use the formula for efficiency of Carnot cycle
n = 1 - T2 / T1
0.35 = 1 - T2 / 700
0.65 = T2 / 700
T2 = 700 × 0.65
T2 = 455 K
Answer:

Total Cost
Differentiate C w.r.t Length
Dimensions are
The radius of the track in the circular motion is 0.164 mm.
<h3>Magnetic force of the of charge</h3>
The magnetic force of the charge is calculated as follows;
F = qvB
<h3>Centripetal force of the charge</h3>
The centripetal force experienced by the charge is calculated as follows;
<h3>The magnetic force is equal to the centripetal force</h3>
<h3>The radius of the track</h3>
The radius of the track is calculated as follows;
Thus, the radius of the track in the circular motion is 0.164 mm.

Hi there!
We can use the derived equation to solve:
, where:
h = height
g = acceleration due to gravity
Plug in the given values. Remember to CONVERT km to m:
32 km = 32 km * 1000 m / 1 km = 32,000 m
t = √(2(32000)/3.4) ≈ <em>137.199 sec</em>
Part 2:
Use the derived equation:
vf = √2gh
vf = √(32000)(3.4) = <em>329.848 m/s</em>
