Can you explain the answer of this question below:A new unit of length...
► Time can be converted as t = (8 x 60) + 20s = 500 seconds
► Now speed given= 1 unit
We know speed = Distance / Time
which implies distance = Speed x Time
Hence, the distance becomes 1 x 500 = 500 units.

Can you explain the answer of this question below:A new unit of length...
To find the distance between the Sun and the Earth in terms of the new unit, we need to calculate the distance that light travels in 8 minutes and 20 seconds. Since the speed of light is unity in the new unit, this distance will be equal to the time taken.

Let's start by converting the time taken into seconds:
8 minutes = 8 * 60 = 480 seconds
20 seconds

Total time taken = 480 seconds + 20 seconds = 500 seconds

Now, since the speed of light is unity, the distance traveled by light in 1 second is also unity. Therefore, the distance between the Sun and the Earth in terms of the new unit is equal to the time taken in seconds, which is 500.

So, the correct answer is option C) 500.

Time can be converted as t=(8x60)+20s=500s now speed given=1unit we know speed=distance/time which implies distance=speedxtime so distance=1x500=500.

Attempt All sub parts from each question.Railway track expansion joint: Expansion and contraction of steel and concrete structure due to seasonal heating and cooling is a common problem found in civil engineering. To combat this problem, engineers put expansion joints to absorb these changes.This problem is compounded on railway tracks. This could lead to rail buckling, known in the industry as “sun kink”, as shown below, and cause the derailment of train. When exposed to temperature variations, the rail tends to vary its length. If this tendency is freely allowed, for a temperaturevariance Δt, the rail length L will vary by ΔL. This length variance can be computed as:ΔL = αLΔtwhere α = expansion coefficient of steel= 11.5 x 10–6 °C.The coefficient of thermal expansion is defined as the fractional increase in length per unit rise in temperature. Traditional railway tracks are of standard lengths. When the tracks are laid, the lengths are joined end to end using “fishplates”—short lengths of steel plate overlapping the joint, and bolted to the ends of the rails. At each joint there must be a short gap (≈ 1/8") between the rail ends, to allow for longitudinal thermal expansion of the rails on hot days.Q. Which of the following statement is true?
