Answer 1

Ответ:

50 мПа = 50000000 Па

Answer 2

Calculation of Pressure Increase in a Railway Wagon

To calculate the increase in pressure inside a railway wagon when loaded with 10 tons and having four wheels with a contact area of 20 cm² each, we can use the formula for pressure:

Pressure (P) = Force (F) / Area (A)

Where: - Force (F) is the weight of the loaded wagon (10 tons converted to newtons) - Area (A) is the total contact area of the wheels

Let's calculate the increase in pressure step by step.

Step 1: Convert Weight to Force

The weight of the loaded wagon is 10 tons. To convert this to newtons, we can use the conversion factor: 1 ton = 1000 kg 1 kg = 9.8 N (acceleration due to gravity)

So, the force due to the weight of the loaded wagon is: F = 10 tons * 1000 kg/ton * 9.8 N/kg

Step 2: Calculate Total Contact Area

The total contact area of the four wheels is: A = 4 wheels * 20 cm²/wheel

Now, let's calculate the increase in pressure.

Step 3: Calculate Pressure Increase

Using the formula for pressure: P = F / A

Substitute the values of force and area to find the increase in pressure.

After calculating the increase in pressure, I'll provide the result.
