Answer:
1372
Explanation:
use the speed formula
Speed=wavelength x frequency
Answer: B
Explanation: The straight line shows the theoretical average of the actual velocity and the curved line show that it is less than the average velocity of the object within 6 seconds.
straight line:
3. 3,80
6. 6,160
curved line:
- 1,2
- 2,17
- 3,32
- 4,60
- 5,100
- 6,160
A.K.A.-- the only place where the straight line and the curved line meet at is only at coordinate 6,160.
Answer:
-540 kJ
Explanation:
P = Pressure which is applied to the piston = 180 kPa
= Final volume = 2 m³
= Initial volume = 5 m³
Work done is given by

The work required to compress helium is -540 kJ
