Answer:
The answer is both technician A and B
Explanation:
Possible indication of by the red brake lamp is faulty brake system, since when the brake pedal is pushed normally it is turned on. Hence this indicates a faulty brake system if it is turned on without pushing the brake pedal.
Also the brake light is turned on when ever there is shortage in brake fluid, this signals that there is a possible fault in the braking system.
Answer:
v/U=0.79
Explanation:
Given u=
Now for the given flow to be possible it should satisfy continuity equation
Applying values in this equation we have
Thus we have
Hence proved
For maximum value of v/U put y =
Thus solving we get using the given values
v/U=0.79
I translated it so I could help, but please try putting the question in English.
You are supposed to use charles' law here. V1/T1 = V2/T2. Temps should be converted to kelvin, so K = C + 273. You are finding V2, so solving for V2 makes it V1*T2/T1 = 0.5 * 313/293 = 0.534 liters
Answer:
6957.04N
Explanation:
Using
vf2=vi2+2ad
But vf = 0 .
So convert 50km/hr to m/s, and you need to convert 61 cmto m
(50km/hr)*(1hr/3600s)*(1000m/km) = 13.9m/s
61cm * (1m/100cm) = .61m
So n
0 = (13.9m/s)^2 + 2a(.61m)
a = 158.11m/s^2
So
using F = ma
F = 44kg(158.11m/s^2) = 6957.04N
