The Earth's crustal plates move due to ____

How much work does the charge escalator do to move 2.30 μC of charge from the negative terminal to the positive terminal of a 3.

loris [4]

Answer:

$6.9\times 10^{-6} J$

Explanation:

We are given that

Charge=q= $2.3\mu C=2.3\times 10^{-6} C$

$1\mu C=10^{-6} C$

Potential difference=V=3 V

We know that

Work done= $V\times q$

Using the formula

Work done by charge to move from the negative terminal to the positive terminal of battery= $2.3\times 10^{-6}\times 3$ J

Work done by charge to move from the negative terminal to the positive terminal of battery= $6.9\times 10^{-6} J$

A. Una onda armónica que se propaga por un medio unidimensional tiene una frecuencia de 500Hz y una velocidad de propagación de

Natasha2012 [34]

Answer:

0.117 m

Explanation:

First of all, we can find the wavelength of the wave in the problem, by using the wave equation:

$v=f\lambda$

where:

v = 350 m/s is the speed of the wave

f = 500 Hz is the frequency of the wave

$\lambda$ is the wavelength

Solving for $\lambda$ ,

$\lambda=\frac{v}{f}=\frac{350}{500}=0.7 m$

This means that the distance between two consecutive points of the wave having a difference of phase of

$\phi=2\pi$

is 0.7 m.

Here we want to find the distance between two points that have a difference of phase of

$\phi'=\frac{\pi}{3}$

So, we can set up the following rule of three:

$\frac{d}{\phi}=\frac{d'}{\phi'}$

where d' is the distance we are looking for. Solving for d',

$d'=d\frac{\phi'}{\phi}=(0.7)\frac{\pi/3}{2\pi}=\frac{1}{6}(0.7)=0.117 m$

A car is moving on the distance 35km in the time 30minutes,stays 20 minutes,the it moves again vith the velocite 60km/h in 25 mi

FinnZ [79.3K]

Velocity = distance/time
v = (35)/(1/2)
v = 70 km/h

60 km/h for 25 minutes
25 minutes = 25/60 hour
distance= velocity * time
d =(60) * (25/60)
d = 25 km

ΔV = { V(initial) - V(final) } / time
v= (70-60) / (45/60)
average velocity = 13.33 km/h
avg veloticy = 3.7 m/s

A student holds two pieces of paper at the top, 10 cm apart. The flat sides of the papers face each other.

Aleksandr [31]

When the student uses a straw to blow a stream of air between the papers, the <span>two pieces of paper come together because the pressure between the two was lowered. This follows the Bernoulli’s Principle. Hope this answers the question. Have a nice day.</span>
