An important measure of LCD monitors is the time in milliseconds (ms) that it takes to turn a pixel on or off. What is this call
AleksandrR [38]

Answer:

Response Time

Explanation:

The time in milliseconds that LCD monitors takes to turn a pixel on or off is called Response time. A lower response time means that the LCD is able to cut down blurring or Ghosting of images thus producing better quality images.

Response time in general terms is the time interval that a system or a person takes to react to given input or event.

A point charge gives rise to an electric field with magnitude 2 N/C at a distance of 4 m. If the distance is increased to 20 m,
worty [1.4K]

Answer:

0.08 N/C

Explanation:

Electric Field: This is defined as the force per unit charge exerted at a point. The expression for electric field is given as,

E = Kq/r².............................. Equation 1

Where E = Electric Field, q = Charge, k = proportionality constant, r = distance.

making q the subject of the equation,

q = Er²/k............................... Equation 2

Given: E = 2 N/C, r = 4 m,

Substitute into equation 2

q = 2(4)²/k

q = 32/k C.

When r is increased to 20 m,

E = k(32/k)/20²

E = 32/400

E = 0.08 N/C.

Hence the electric Field = 0.08 N/C

all bearings are made by lebng spherical drops of molten metal fall inside a tall tower – called a shot tower – and solidify as
Wewaii [24]

Answer:

Part b)

h = 78.5 m

Part c)

v = 39.24 m/s

Explanation:

Part b)

If ball need t = 0 to t = 4 s then height of the tower is the total displacement of the ball in t = 4 s interval

here if ball start from rest

then its displacement is given as

\Delta y = \frac{1}{2}gt^2

\Delta y = \frac{1}{2}(9.81)(4^2)

\Delta y = 78.5 m

Part c)

Speed of the bearing at the end of the motion of the ball

v_f = v_i + at

v_f = 0 + (9.81)(4)

v_f = 39.24 m/s
