Answer:

65.2 %

Explanation:

Let Q1 = Heat absorbed by the system

Q2 = Heat released by the system

e= (1 - (Q2/Q1)) x 100

e= (1 - (750/2150)) x 100

e= (1 - 0.348) x 100

e= 0.652 x 100

e= 65.2 %

A particle moving uniformly along the x axis is located at 11.3 m at 0.588s and at 3.38 m at 4.67s. Find the displacement during
Ad libitum [116K]

The displacement is

     (position at the end of the time interval)
minus
     (position at the beginning of the time interval).

Displacement = (3.38m - 11.3m) =  -7.92 meters.

The time labels aren't needed to calculate displacement. 
They're only there to confuse us and to see whether we
really know what we're doing.

The particle of 2 velocities 10m/s due east and 12m/S in the direction 30N/E. What is the resultant velocity and the direction?
Paha777 [63]

Answer:

See below

Explanation:

East components are   10    and    12 cos 30   = 20.392 m/s

North component =  12 sin 30 = 6 m/s

Resultant velocity = sqrt ( 20.392^2 + 6^2) = <u>21.26 m/s </u>

  direction   arc tan   (6/20.392) = <u>16.4 degrees N of east </u>
