What is potential difference measured in?

2 answers:

5 0

Potential difference is the work done per unit charge. A potential difference of 1 Vmeans that 1 joule of work is done per coulomb of charge. ( 1 V = 1 J C-1) Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.

Dominik [7]

Answer: 17.59 Hz and 4.87 m

Explanation:

The fundamental frequency of the sound from an open-open pipe is given as

f= $\frac{v}{2L}$

where v= 343 m/s

L= 32 feet= $\frac{32}{3.281}$ = 9.75 m

So,

f= $\frac{343}{2*9.75}$ = 17.59 Hz

The length of open-closed tube is related to frequency by formula

f= $\frac{v}{4L}$

or L= $\frac{v}{4f}$

L= $\frac{343}{4*17.59}$

L= 4.87 m

Apply a force of 50 N right to the box. Describe the motion of the box using physics terms (i.E. Velocity, acceleration, displac

Nikitich [7]

When unbalanced force is acting on the system of mass then as per Newton's II law we can say

$F_{net} = ma$

here we have

$a = \frac{F}{m}$

now since the force and mass both given to us so we can find acceleration of object from this

now when 50 N force is applied on a box then this 50 N force is unbalanced force on it and it will produce acceleration to the box

So here we can say that box will accelerate with constant acceleration and hence its velocity will linearly increase with time.

Now the displacement of the object will be given as

$d = v_i * t + \frac{1}{2} at^2$

so here the displacement will be a quadratic function of time and increases with time as well

so here overall the motion will be of constant acceleration, uniformly increasing velocity and displacement will be a quadratic function of time

Answer:

Explanation:

The electric field inside of a conductor is 0 because the conduction electrons are pushed to the outer edges of the conductor. The surface of the conductor still has charge.

A car travels 35 km west and 90 km north in two hours what is its average velocity?

blagie [28]

Average velocity = Total Displacement / Total time taken

Total displacement is the distance from starting to end point.

35km west then 90km north. When you will draw this and connect starting to end point. You will get a right angled triangle.

So displacement = $\sqrt{35^2+90^2}$

= 96.56 km

So, Total displacement = 96.56 km

So, Average Velocity = 96.56 / 2 = 48.28 km/hr
