Answer:

The correct option is;

C. The intensity control

Explanation:

The trace is the visible lines displayed on a CRT formed by the electron beam movement.

The brightness of the displayed trace can be adjusted by increasing or reducing the intensity control as the sweep of the analog oscilloscope is increased or decreased

The sweep of an oscilloscope is an indication of the speed with which the trace is allowed to sweep across the screen of the oscilloscope while being visible. The sweep is measured in seconds per division.

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:

Cost = $2527.2 per month.

Explanation:

Given that

Discharge ,Q = 130 L/min

 So

Q=0.13\ m^3/min

Cost =  $0.45 per cubic meter

1 month = 30 days

1 days = 24 hr = 24 x 60 min

1 month = 30 x 24 x 60 min

1 month = 43,200 min

Lets xm^3\ water\ waste\ in\ a\ month

x = 0.13 x 43,200

x=5616\ m^3

So the total cost = 5616 x 045 $

Cost = $2527.2 per month.

Suppose Q1 (0.0, - 3.0 M, 0.0) = 4.0 nC, Q2 (0.0, 3.0 m, 0.0) = 4.0 nC, and Q3 (4.0 m, 0.0, 0.0) = 1.0 nC.
frozen [14]

Answer:

Explanation:

Force on Q₃ due to charge Q₁

= 9 x 10⁹x 4 x 10⁻⁹ x1 x 10⁻⁹ /  5²

= 1.44 x 10⁻⁹ N

Force due to Q₂ will also be 1.44 x 10⁻⁹ N

component of these forces along x axis

-= 2 x 1.44 x 10⁻⁹ cosθ

= 2.88 x  10⁻⁹  x 4/5

= 2.30x10⁻⁹  N along x axis.

The y-component will calcel out.

b ) In this case , Q₁ will repel and Q₂ will attract.

In this case Q₁ will repel and Q₂ will attract. Component along y - axis will be same as earlier one or 2.30x10⁻⁹  N . Component along x axis will cancel out.

c ) Electric field in case 1 and case 2 will be

= 2.30x10⁻⁹  / 1 x 10⁻⁹

= 2.3 N / C , because field is force per unit charge. The sane field will be in case 2 .

Can anybody teach me how to make an app with flask and pygame together?​
sweet [91]

Answer:

no :-(

Explanation:

Are you sure these technologies fit together?

As I understand it, flask is a library to write web services using python. It will essentially serve HTML pages and perhaps REST interfaces?

Pygame is a local machine abstraction layer to graphics and other i/o. I don't think it will run in a browser.

What is your plan?
