Answer:
Explanation:
Frequency is oscillations per second.
So we have to find the Number of seconds she paced.
2 minutes = 2 X 60
= 120 seconds
Therefore,
Her frequency = 10 / 120
= 1/12 Hertz
Answer: the frequency observed will be 1269.45hz
Explanation: according to the doppler effect,
Apparent frequency f' = (c/(c+u))*f
f = real freq of sound of moving sound source
c = speed of sound in air
u = speed of moving sound source
f' = (343/(343+33.6))*1395
f' = 1269.45hz
Second law of physics. F = MA
200 = 25A

The magnitude of other charge will be 1 × 10⁻² coulomb
The formula of electrostatic force is
Electrostatic force = K q1 q1 / r²
where k is the coulomb's constant whose value is 9 × 10⁹
q1 and a2 are the magnitude of charges
and r is the distance between them
magnitude of the force given to us is 9.0 × 10⁻⁵ newtons
magnitude of one charge = 1.0 × 10⁻⁶ coulomb
Force = K q1 q2 / r²
9.0 × 10⁻⁵ = ( ( 9 × 10⁹ ) × ( 1.0 × 10⁻⁶ ) × q2 ) / 1
9.0 × 10⁻⁵ = 9 × 10³ × q2
10⁻² = q2
Charge on q2 is 1 × 10⁻² coulomb
So the magnitude of the second charge is came out to be 1 × 10⁻² coulomb after applying the formula of electrostatic force.

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.
