Use the distance swan and the time elapsed in that interval.

Average velocity = distance / time

Average velocity = [4.0 m + 3.0m] / 3.2 s = 2.1875 m/s

the current flowing in an appliance connected to a 120V source is 2A. How many kilowatt-hours of electrical energy does the appl
skad [1K]

Answer:

0.96 kWh

Explanation:

First of all, we can find the power of the appliance using the formula:

P=VI

where

V = 120 V is the voltage of the source

I = 2 A is the current

Substituting,

P(120 V)(2 A)=240 W = 0.24 kW

Now we want to find the amount of energy used by the applied in a time of

t = 4 h

The amount of energy is given by

E=Pt

where

P = 0.24 kW

t = 4 g

Substituting,

E=(0.24 kW)(4 h)=0.96 kWh

Kryger [21]
The first one is correct.  It shows her paddling at 8mph north and the water moving 6mph west.  Importantly it also has the vectors added correctly.  You draw all the vectors head to tail then the resultant vector is drawn from the base of the first one to the head of the last one with the arrow pointing in that direction.

An infinite line of charge with charge density λ1 = -2 μc/cm is aligned with the y-axis as shown. 1) what is ex(p), the value of
Natasha2012 [34]

As we know by Gauss's law that

\int E.dA = \frac{q}{\epsilon_0}

so for line charge the gaussian surface is cylindrical in shape

so we will have

E(2\pi RL) = \frac{\lambda L}{\epsilon_0}

now by rearranging the terms

E = \frac{\lambda}{2\pi \epsilon_0 R}

so here we will have to find the x component of electric field so it is given by above equation

E_x = \frac{\lambda}{2\pi \epsilon_0 x}

here x = distance from the wire where we need to find electric field
