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.
Also remember that the acceleration of the projectile is 9.8 ms-2 towards the ground throughout the trajectory, even at the very top. Notice that at the maximum height the vertical velocity is zero and that the acceleration due to gravity is negative since it acts to the ball

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:
1/2
Explanation:
The energy stored in a capacitor is given by
where
C is the capacitance
V is the potential difference
Calling the capacitance of capacitor 1 and its potential difference, the energy stored in capacitor 1 is
For capacitor 2, we have:
- The capacitance is half that of capacitor 1:
- The voltage is twice the voltage of capacitor 1:
so the energy stored in capacitor 2 is
So the ratio between the two energies is
