Hi,
The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
Answer:
a=7.384 m/s^2
Explanation:
let T be the tension in the string, m= mass
and a= acceleration
from the FBD in the attachment we can write
Tcos37°= mg
Tsin37° =ma
dividing both the equations we get
tan37° =a/g
therefore a=g×tan37°
a= 9.81×0.7535 = 7.384 m/s^2
the magnitude of the acceleration a of the train = 7.384 m/s^2
Answer:
7.5 seconds
Explanation:
because wattsXtime=Joules so 120X__=900. 900 divided by 120= 7.5
Geothermal energy because the heat transfer to heat
