A charge of 4.5x10^-5 C is placed in an electric field with a strength of 2.0x10^4 N/C. What is the electric force acting on the

Alex

Answer:

0.9 N

Explanation:

The electric force acting on a charge is given by:

$F=qE$

where

q is the magnitude of the charge

E is the strength of the electric field

In this problem, we have

$q=4.5\cdot 10^{-5}C$ is the charge

$E=2.0\cdot 10^4 N/C$ is the strength of the electric field

Substituting into the equation, we find

$F=(4.5\cdot 10^{-5}C)(2.0\cdot 10^4 N/C)=0.9 N$

Consider a traveling wave described by the formula

Harrizon [31]

Answer:

The wave is traveling in the +x direction.

Explanation:

The equation of a wave is given by the formula as :

$y(x,t)=A\ sin(kx-\omega t)$

Here,

A is the amplitude of wave

$(kx-\omega t)$ is the phase of wave

$\omega$ is the angular frequency of the wave

We need to find the correct statement out of given options. The given equation can be rewritten as :

$y(x,t)=A\ sin(\omega t-kx)$

Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
