Answer:

Just maintain the course you are on and your speed.

Explanation:

When you see a green and a white light, then from the port (left) side you will start coming across another craft. You are the stand-alone craft in this scenario and therefore should stay consistent with your pace and direction. The other craft must take important and early measures to keep the craft away from you.

Assume that a uniform magnetic field is directed into thispage. If an electron is released with an initial velocity directedfrom

Feliz [49]

Answer:

B). to the right

Explanation:

Since the direction of magnetic field is into the page

So here we know that

$B = B_o(-\hat k)$

now the velocity is from bottom to top

so we have

$v = v_o \hat j$

now the force on the moving charge is given as

$\vec F = q(\vec v \times \vec B)$

now we have

$\vec F = (-e)(v_o \hat j \times B_o(-\hat k))$

$\vec F = e v_o B \hat i$

so force will be towards Right

What is the velocity of an electron that has a de Broglie wavelength approximately the length of a chemical bond? Assume this le

melomori [17]

Answer : The velocity of an electron is, $6.1\times 10^{6}m/s$

Explanation :

According to de-Broglie, the expression for wavelength is,

$\lambda=\frac{h}{p}$

and,

$p=mv$

where,

p = momentum, m = mass, v = velocity

So, the formula will be:

$\lambda=\frac{h}{mv}$ .............(1)

where,

h = Planck's constant = $6.626\times 10^{-34}Js$

$\lambda$ = wavelength = $1.2\times 10^{-10}m$

m = mass of electron = $9.11\times 10^{-31}kg$

v = velocity of electron = ?

Now put all the given values in formula 1, we get:

$1.2\times 10^{-10}m=\frac{6.626\times 10^{-34}Js}{(9.11\times 10^{-31}kg)\times v}$

$v=6.1\times 10^{6}m/s$

Thus, the velocity of an electron is, $6.1\times 10^{6}m/s$
