Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth

Newton's Second law of motion states that "<em>the </em><em>acceleration</em><em> of an object depends upon </em><em>two</em><em> </em><em>variables</em><em> – the net force acting on the object and the mass of the object.</em>"

In our case the mass of the book and the force of gravity

A mixture of 454 kg of applesauce at 10 degrees Celsius is heated in a heat exchanger by adding 121300 kJ. Calculate the outlet
stira [4]

Explanation:

The given data is as follows.

           Mass of apple sauce mixture = 454 kg

           Heat added (Q) = 121300 kJ

 Heat capacity (C_{p}) of apple sauce at 32.8^{o}C = 4.0177 kJ/kg^{o}C

So, Heat given by heat exchanger = heat taken by apple sauce

                            Q = mC_{p} \Delta T

or,                    Q = mC_{p} (T_{f} - T_{i})  

Putting the given values into the above formula as follows.

                     Q = mC_{p} (T_{f} - T_{i})  

              121300 kJ = 454 kg \times 4.0177 kJ/kg^{o}C \times (T_{f} - 10)

                      T_{f} = 76.5^{o}C

Thus, we can conclude that outlet temperature of the apple sauce is 76.5^{o}C.

A chemical engineer has determined by measurements that there are 69.0 moles of hydrogen in a sample of methyl tert-butyl ether.
Juli2301 [7.4K]
<span>5.75 moles The formula for methyl tert-butyl ether is (CH3)3COCH3, so a single molecule has 5 carbon, 12 hydrogen, and 1 oxygen atoms. So for every 12 moles of hydrogen, there's 1 mole of oxygen. So simply divide the number of moles of hydrogen by 12 to get the number of moles of oxygen. 69.0 / 12 = 5.75 Therefore there's 5.75 moles of oxygen in the sample.</span>

A student determines the volume of a cube to be 4.6 cm?
pav-90 [236]

Answer:

6.98%

Explanation:

% error= |experimental value - actual value|/actual value × 100

Experimental value= 4.6 cm

Actual value= 4.3 cm

% error = |4.6-4.3|/4.3 × 100

% error = 6.98%
