Answer:
1400 N
Explanation:
→ Force = Mass × Acceleration
→ F = (70 × 20) N
→ <u>F = 1400 N</u>
Multiply the numerator and denominator of the first fraction by 3. Multiply the numerator and denominator of the second fraction by 4. Subtract. 9 twelfths minus 4 twelfths equals 5 twelfths.
Right now (late 2015), the difference is about 256 miles.
The geographic north pole is the point where the north end of the
Earth's rotation axis sticks out of the ground. As long as the Earth
continues to spin on the same 'pencil', the geographic poles don't move.
The magnetic north pole is the point on Earth that magnetic compasses
point to. The magnetic poles are the result of the flowing, shifting liquid
iron in the Earth's core, and they move. The magnetic north pole is presently
somewhere in the Canadian Arctic territory, about 256 miles south of the
geographic pole, and moving westward towards Russia at about 35 miles a year.
Hey there!
In this case, it is possible to solve this problem by using the widely-known steam tables which show that at 90 °C, the pressure that produces a vapor-liquid mixture at equilibrium is about 70.183 kPa (Cengel, Thermodynamics 5th edition).
Moreover, for the calculation of the volume, it is necessary to calculate the volume of the vapor-liquid mixture, given the quality (x) it has:
Thus, since 8 kg correspond to liquid water, 2 kg must correspond to steam, so that the quality turns out:
Now, at this temperature and pressure, the volume of a saturated vapor is 2.3593 m³/kg whereas that of the saturated liquid is 0.001036 m³/kg and therefore, the volume of the mixture is:
This means that the volume of the container will be:
