Answer:

<h3>The answer is 0.54 m</h3>

Explanation:

The wavelength of a wave can be found by using the formula

$\lambda = \frac{c}{f} \\$

where

c is the velocity

f is the frequency

So we have

$\lambda = \frac{457}{841} \\ = 0.543400713...$

We have the final answer as

Hope this helps you

At what distance r from a point charge is the electric potential due to that point charge 0 v?

galben [10]

Answer:

Infinite Distance

Explanation:

The electric potential due to a point charge can be expressed by the following equation:

$V=\frac{kQ}{r}$

Here,

V is the electric potential due to the point charge

k is the proportionality constant

Q is the magnitude of the point charge

r is the distance from the charge

As the value of r increases, the value of V decreases since there is an inverse relation between the two. The value of V can be absolutely 0 when the distance from the charge is infinite i.e. r is infinite. Mathematically, dividing a number by infinity results in zero. Also theoretically speaking, at infinite distance the electric field lines won't approach and hence the electric potential would be zero.

A deer walks 17.0 m south and then 12.0 m north. Find both the magnitude of its displacement and the distance traveled.

Zepler [3.9K]

Answer:

Explanation:

Displacement involves direction and distance. In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.

So the answer is A) 5.0 m, 29.0 m

A 65 kg student sits 3 m away from a 70 kg student. What is the magnitude of the gravitational force between the two students?

LiRa [457]

Answer:

$F=3.37\times 10^{-8}\ N$

Explanation:

Given that,

Mass of student 1, m₁ = 65 kg

Mass of student 2, m₂ = 70 kg

The distance between the students, d = 3 m

We need to find the magnitude of the gravitational force between the two students. The formula for the magnitude of the gravitational force between two masses is given by :

$F=G\dfrac{m_1m_2}{d^2}\\\\F=6.67\times 10^{-11}\times \dfrac{65\times 70}{(3)^2}\\F=3.37\times 10^{-8}\ N$

So, the gravitational force between the two students is $3.37\times 10^{-8}\ N$ .
