Answer:
Technician A
Explanation:
An oxygen sensor is being tested with a digital multimeter using the MIN/MAX function. The readings are: minimum = 78 mV; maximum = 932 mV; average = 442 mV. Technician A says that the engine is operating normally. Technician B says that the oxygen sensor is skewed too rich. Which technician is correct?
an oxygen sensor detects te amount of oyen in an engine at the exhaust pipe.
if the oxygen sensor detects oxygen at the above boundary condition, ten the engine is in good working condition
Answer:
Magnitude of the acceleration due to gravity on the planet = 2.34 m/s²
Explanation:
Time period of simple pendulum is given by
, l is the length of pendulum, g is acceleration due to gravity value.
We can solve acceleration due to gravity as
Here
Length of pendulum = 1.20 m
Pendulum executes simple harmonic motion and makes 100 complete oscillations in 450 s.
Period,
Substituting
Magnitude of the acceleration due to gravity on the planet = 2.34 m/s²
Answer:
ω = 3.66 rad/s
Explanation:
Given that
L= 1 m
M = 270 g = 0.27 kg
m = 3 g
u= 250 m/s
v= 140 m/s
We know that moment of inertia of the rod about it center
I=0.0225 kg.m²
The initial angular momentum
L₁ = m u r
Final angular momentum
L₂= I ω+m v r
Here r= L/4
r= 0.25 m
There is no any external torque ,it means that angular momentum will be conserve
L₁ = L₂
m u r = I ω+m v r
m r (u - v)=I ω
Now by putting the values
m r (u - v)=I ω
0.003 x 0.25 x (250- 140)=0.0225 x ω
ω = 3.66 rad/s
