Hey there, the answer is .............................. About 0.7 m/sec^2
<span>
Acceleration is the change in speed / time </span>
<span>Change in speed is 60 m/sec </span>
<span>Time is 1 minute 25 second. Convert that to seconds. </span>
<span>Divide the change in speed by the time in seconds.
About 0.7 m/sec^2
</span><span>So the acceleration is - 60 / 85 = - 0.71 m/s^2
HOPE I HELPED!!!!!!!!!!</span>
Answer:
The thermal conductivity of the wall = 40W/m.C
h = 10 W/m^2.C
Explanation:
The heat conduction equation is given by:
d^2T/ dx^2 + egen/ K = 0
The thermal conductivity of the wall can be calculated using:
K = egen/ 2a = 800/2×10
K = 800/20 = 40W/m.C
Applying energy balance at the wall surface
"qL = "qconv
-K = (dT/dx)L = h (TL - Tinfinity)
The convention heat transfer coefficient will be:
h = -k × (-2aL)/ (TL - Tinfinty)
h = ( 2× 40 × 10 × 0.05) / (30-26)
h = 40/4 = 10W/m^2.C
From the given temperature distribution
t(x) = 10 (L^2-X^2) + 30 = 30°
T(L) = ( L^2- L^2) + 30 = 30°
dT/ dx = -2aL
d^2T/ dx^2 = - 2a
You need to know the speed and direction of object

➷ It would be 'when they have like charges.'
'Like charges' means the same charge. For example, two positive charged objects have like charges.
