To solve this problem it is necessary to apply the concepts related to density in relation to mass and volume for each of the states presented.
Density can be defined as
Where
m = Mass
V = Volume
For state one we know that
For state two we have to
Therefore the total change of mass would be
Therefore the mass of air that has entered to the tank is 6.02Kg
Answer:
use the percentage error relation
Explanation:
The percentage error in anything is computed from ...
%error = ((measured value)/(accurate value) -1) × 100%
__
The difficulty with voltage measurements is that the "accurate value" may be hard to determine. It can be computed from the nominal values of circuit components, but there is no guarantee that the components actually have those values.
Likewise, the measuring device may have errors. It may or may not be calibrated against some standard, but even measurement standards have some range of possible error.
Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
