Answer:
0.0002778° are equivalent to one second of arc.
Explanation:
1 degree consists of 60 arc minutes.
1 arc minutes consists of 60 arc seconds.
It can also be written as:
1 minute of arc comprise of 1/60 degree.
1 second of arc comprise of 1/60 arc minutes.
So,
<u>1 second of arc comprise of (1/60)*(1/60) degree.</u>
Thus,
Thus,
<u>0.0002778° are equivalent to one second of arc.</u>
Answer:
increases by a factor of 6.
Explanation:
Let us assume that the initial cross sectional area of the pipe is A m² while the initial velocity of the water is V m/s², hence the flow rate of the water is:
Initial flow rate = area * velocity = A * V = AV m³/s
The water speed doubles (2V m/s) and the cross-sectional area of the pipe triples (3A m²), hence the volume flow rate becomes:
Final flow rate = 2V * 3A = 6AV m³/s = 6 * initial flow rate
Hence, the volume flow rate of the water passing through it increases by a factor of 6.

Answer:
C. The intensity control
Explanation:
The focus adjust the sharpness of the trace. The Intensity knob adjusts the brightness of the trace by adjusting the potential of a grid controlling number of electrons reaching the screen. The level control varies the voltage required to generate a trigger. Slope control determines whether the trigger point is on the rising or the falling edge of a signal.
The correct option is therefore the intensity control.
Answer:
Space Cushion
Explanation:
Having an adequate Space Cushion provides a driver with the time and space necessary to react to potential and immediate hazards in the driving scene.
