Answer:

Pressure = force/area

= 650N/0.12m^2

= 5416.7 to 1 d.p

I got 650N by taking the gravitational field on earth to be 10N/kg.

Weight = mass x gravitational field

= 65 x 10N/kg

= 650

Answer is 5416.7 pascals (Pa)

Or

5308.3 Pa

if gravitational field was taken to be 9.8N/kg

Hope this helps!

Ronch [10]

Time taken to reach water :

t = \dfrac{D}{v}\\\\t=\dfrac{6.78}{8.06}\ s\\\\t=0.84\ s

Now, initial vertical speed , u = 0 m/s.

By equation of motion :

h = ut +\dfrac{at^2}{2}

Here, a = g = acceleration due to gravity = 9.8 m/s².

So,

h = 0(t) +\dfrac{9.8\times 0.84^2}{2}\\\\h=3.46\ m

Therefore, the height of the bridge is 3.46 m.

Hence, this is the required solution.

A syringe initially holds a sample of gas with a volume of 285 ml at 355 k and 1.88 atm. To what temperature must the gas in the
Mnenie [13.5K]

Answer:

The answer to your question is 720.5°K

Explanation:

Data

Volume 1 = 285 ml

Temperature 1 = 355 °K

Pressure 1 = 1.88 atm

Volume 2 = 435 ml

Temperature 2 = ?

Pressure 2 = 2.5 atm

Formula

To solve this problem use the combined gas law

               P1V1 / T1 = P2V2 / T2

- Solve for T2

               T2 = T1P2V2 / P1V1

- Substitution

               T2 = (355)(2.5)(435) / (1.88)(285)

- Simplification

               T2 = 386062.5 / 535.8

- Result

                T2 = 720.53°K

Conclusion

The gas must be heated to 720.5°K
