You measure the velocity of a drag racer that accelerates with constant acceleration. You want to plot the data and determine th
Ivenika [448]

Answer:

a) Linear equation

Explanation:

Definition of acceleration

a=\frac{dv}{dt}\\

if a=constant and we integrate the last equation

v(t)=v_{o}+a*t

So the relation between the time and the velocity is linear. If we plot the velocity in function of time, the plot is a line, and the acceleration is the slope of this line.

The capacitance of a fully-charged capacitor is 11 F. Determine the capacitor's capacitance when it is half charged.
Tcecarenko [31]

Answer:

The capacitance is 11 F for half and fully charged capacitor.

Explanation:

Capacitance of capacitor is given by the expression

             C=\frac{\epsilon A}{d}

Where ε is the  vacuum permittivity, A is the area of plates and d is the separation between plates.

So capacitance does not depend upon charge and potential. So capacitance fully and half charged capacitors are same.

Here the capacitance is 11 F for half and fully charged capacitor.

Q1: A cyclist brakes to a stop. His thinking distance was 1m and his braking distance was 3m. What was his overall stopping dist
weeeeeb [17]

Answer:

1.) 4m

2.) 37 m

3.) 62m

4.) 2.5 s

Explanation:

1.) Given that the

Thinking distance = 1m

Breaking distance = 3m

Stopping distance = breaking distance + thinking distance

Stopping distance = 1 + 3 = 4m

2.) Given that the

Stopping distance = 52 m

Thinking distance = 15m

Breaking distance = 52 - 15 = 37m

3.) The stopping distance = 76m

Thinking distance = 14m

Breaking distance = 76 - 14 = 62m

It take the brakes 62m to slow the car down to a stop.

4.) Given that a lorry travels 28m when stopping from a speed of 4m/s. If its braking distance was 18m, what was the driver’s reaction time?

Thinking = stopping distance - braking distance

Thinking distance = 28 - 18 = 10m

Speed = distance/time

4 = 10/reaction time

Reaction time = 10/4

Reaction time = 2.5 s

5.) Question incomplete

In an LRC circuit, why does the sum of the voltages around the circuit not equal the applied voltage as kirchhoff’s rule require
wel

Kirchhoff's loop rule is always true.

The foundation of circuit analysis is Kirchhoff's Laws for current and voltage. We have the fundamental set of tools required to begin evaluating circuits with these two principles, In an RLC circuit, the most fundamental elements of a resistor, inductor, and capacitor are connected across a voltage supply.

Which of these helps you understand what people are saying to you? A. Interrupting them B. Looking away while they're speaking C
densk [106]
I believe the answer is <span> D. Thinking about what they're saying
Interrupting them will make them unable to finish their full message/thought to you. Looking away while they're speaking will make you reduce your attention and unable to process the information properly. Thinking about how you'll response also limit your attention to them and could make you cloud your opinion and misinterpret what's they're saying.</span>
