Answer:
If the atoms get two close then the nuclii will repell each other.
Explanation:
Since electrons are negative they are attracted to the nucleus because it is positive. If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii.
Answer:
In-car temperature is controlled in a variable displacement compressor system by varying the capacity of the <em>refrigeration</em> not by cycling the <em>compressor </em>on and off.
Explanation:
A Variable Displacement Compressor (VDC) works in a separate and rather more efficient manner than the fixed displacement compressor (FDC). <em>The VDC automatically regulates the cooling effect of the refrigerator by changing its pumping capacity by means of a "wobbling piston" system. </em>
<em></em>
During times of peak load, the refrigeration pumping capacity is increased, delivering a large flow rate of refrigerant, thus giving a high refrigerating effect. The reverse happens during times of load refrigeration load.
<em>The fixed compressor tries to vary the temperature of the car by simply switching off the compressor</em>, and turning it on during times of low and peak loads.
You should use math on your mind and you should balance the bottle
Explanation:
The angular momentum is given by the moment of inertia, multiplied by the angular speed of the rotating body:
The angular speed is given by:
Now, we calculate the angular momentum:
The average torque is defined as:
is the angular acceleration, which is defined as:
We have to calculate :
Now, we calculate the angular acceleration:
Finally, we can know the average torque:
