Answer:
122.76J
Explanation:
Given data
work done= 372 Joules
efficiency= 33%
Required
We want to compute the value of the work that is 33%
= 33/100* 372
= 0.33*372
= 122.76J
Hence 122.76J of work is transferred from the engine to the exhaust
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
The answer would be D, negative acceleration
Answer:-2.61 m/s
Explanation:
This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum must be equal to the final momentum :
(1)
Where:
(2)
(3)
is the mass of the first car
is the velocity of the first car, to the North
is the mass of the second car
is the mass of the second car, to the South
is the final velocity of both cars after the collision
(4)
Isolating :
(5)
(6)
Finally:
(7) This is the resulting velocity of the wreckage, to the south
Answer:
Explanation:
Given that
Stored energy ,
Angular speed ,
Lets take moment of inertia of the flywheel = I
As we know that stored energy in the flywheel is given as
Now by putting the values in the above equation we get
Therefore the moment of inertia of the flywheel will be
The answer will be C.
