Answer:

T = 0.01 s

Explanation:

Given that,

The frequency of the beats of a hummingbird, f = 100 Hz

We need to find the period of the hummingbirds flaps. Let the time is t. We know that the relation between frequency and time period is given by :

T = 1/f

Put all the values,

T = 1/100 = 0.01 s

So, the time period of the humming bird is 0.01 s.

A rod (length = 2.0 m) is uniformly charged and has a total charge of 5.0 nC. What is the electric potential (relative to zero a

Ksenya-84 [330]

Answer:

The electric potential is $V = 15.6 V$

Explanation:

From the question we are told that

The length of the rod is $L = 2.0 \ m$

The total charge of the rod is $q =5.0 nC = 5.0*10^{-9} C$

The length from the center is $d = 3.0 \ m$

The diagram illustrating the setup for this question is shown on the first uploaded image

From the diagram the potential at point A $dl$ is mathematically represented as

$dV = K \frac{dq}{l}$

Where K is the coulomb constant with a value $K = 9*10^9 \ Nm^2 /C^2$

where q is the charge in charge the rod relative to its distance from A is mathematically represented as

$dq = \frac{q}{L} dl$

This a small unit length of the rod

So $V = \frac{q}{L} \int\limits^4_2 {\frac{dl}{l} } \,$

=> $V = k\frac{q}{L} ln [\frac{4}{2} ]$

$V = k\frac{q}{L} ln2$

Substituting values

$V = 9* 10^9 * \frac{5*10^{-9}}{2} * ln 2$

$V = 15.6 V$

A radio have a wavelength of 0.3m and travels at a speed of 300,000,000 m/s. What is the frequency of this wave?

Ilya [14]

The frequency of the wave is $1\cdot 10^9 Hz$

Explanation:

The frequency, the wavelength and the speed of a wave are related by the following equation:

$c=f \lambda$

where

c is the speed of the wave

f is the frequency

$\lambda$ is the wavelength

For the radio wave in this problem,

$\lambda = 0.3 m$

$c=300,000,000 m/s = 3\cdot 10^8 m/s$

Therefore, the frequency is:

$f=\frac{c}{\lambda}=\frac{3\cdot 10^8}{0.3}=1\cdot 10^9 Hz$
