Answer:
92km
Explanation:
Given parameters:
Duration of the journey = 6hrs
Average speed = 58km/hr
Now, let us find the total distance of the journey;
Distance = Speed x time
Distance = 58 x 6 = 348km
So;
Average speed for the first 4hrs = 64km/hr
Time = 4hrs
Distance = 64 x 4 = 256km
For the rest of the journey, the student will cover;
= 348km - 256km
= 92km
Answer: When 
Explanation:
According to first law of thermodynamics, energy can neither be created nor be destroyed. It can only be transformed from one form to another.
= change in enthalpy
P = pressure
= change in volume
=Change in internal energy
q = heat absorbed or released
w = work done on or by the system
Thus for ,
The heat evolved or absorbed by the system in a physical or chemical process, equal the change in enthalpy of the system when
Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
I would need an example or photo to give an answer.
