Answer:
Explanation:
Given: that,
Angle of inclination of the surface, 
mass of the crate, 
Force applied along the surface, 
distance the crate moves after the application of force, 
a) work done = F× s
work done = 230 × 1.1
work done = 253 J
b) Work done by the gravitational force:
where:
g = acceleration due to gravity
h = the vertically downward displacement
Now, we find the height:
So, the work done by the gravity:
∵direction of force and displacement are opposite.
= - 343.54J
c)
The normal reaction force on the crate by the inclined surface:
d)
Total work done on crate is with respect to the worker:
Answer and Explanation:
Internal Energy:
Internal energy associated to a system is the total amount of energy of a system excluding both the kinetic and potential energies as a whole for any external effects and is only accountable for any change in the energies of the system due to the internal order or states. It can be considered as that energy of the system essential to make it ready for any provided state.
Specific heat:
It is the specific amount of heat that is contained in a unit mass of any substance needed to bring about [tex]1^{\circ} rise in its temperature.
Entropy:
It can be defined as the degree of disorientation of the molecules or the extent of disorder of the system. It is the lack in thermal energy of the system to get converted into work (mechanical).
Temperature:
The measure of the heat intensity of a substance on a given standard scale.
Answer:
The answer is: measuring instrument
Explanation:
The researcher develops test to measure the variables she is interested in. So, they are her measuring instrument.
