SONAR, satellite radar, GPS, and deep-sea diving vessels all contribute
to accurate MEASUREMENT of the depth and motion of the sea floor, and
of the motion of the continents.
Once the measurements are known, they can be analyzed to determine
whether OR NOT they support the idea of continental drift, or some other
hypothesis.
Real scientists don't go out looking for evidence to support the ideas
that they want supported. That kind of approach to research is found
more in the Flat Earth department.
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:
<em>1.07m/s²</em>
Explanation:
From the question we are given the following
applied force Fapp = 450N
mass of the safe m = 100kg
Weight of the safe W = 980N
coefficient of kinetic friction n = 0.35
Required
Acceleration of the safe
According to Newton's second law
\sum Fx = ma
Fapp - Ff = ma
Ff is the frictional force
Fapp - nmg = ma
450 - 0.35(100)(9.8) = 100a
450 - 343= 100a
107 = 100a
a = 107/100
a = 1.07m/s²
<em>Hence the acceleration of the safe is 1.07m/s²</em>
