What is the velocity of a wave with a wavelength of 1.5m and a frequency of 500 Hz

Schach [20]

Wave speed = (wavelength) x (frequency)

= (1.5 m) x (500 / sec)

= 750 m/s .

3. 3.0*1015 electrons are removed from one side of a parallel plate capacitor and travel to the other side of the capacitor. You

natima [27]

Answer:

True

$Q = 480 \mu C$

Explanation:

As we know that total charge is always quantized and in the terms of multiples of charge of single electron

so we have

Q = Ne

here we know that

$N = 3.0 \times 10^{15}$

also we know that

$e = 1.6 \times 10^{-19} C$

so we have

$Q = (3.0 \times 10^{15})(1.6 \times 10^{-19} C)$

$Q = 480 \mu C$

Since this charge is in multiple of micro coulomb units so yes it is possible to measure it

and the magnitude of this charge is given as

$Q = 480\mu C$

A car is moving 14.4 m/s. It decelerates at -1.55 m/s^2 for 4.26 s. It then accelerates at 1.83 m/s^2 until it reaches 11.8 m/s.

Aleonysh [2.5K]

The total time is 6.45 s

Explanation:

The motion of the car is a uniformly accelerated motion, so we can use suvat equations.

In the first part,

$u_1 = 14.4 m/s$ (initial velocity)

$a_1 = -1.55 m/s^2$ (acceleration)

$t_1=4.26 s$ (time of the first part)

So, we can find the velocity of the car after the first part, by using

$v_1 = u_1 +a_1 t_1 =14.4+(-1.55)(4.26)=7.8 m/s$

This is therefore the initial velocity of the second part:

$u_2 = v_1 = 7.8 m/s$

$a_2 = 1.83 m/s^2$ (acceleration in the second part)

$v_2 = 11.8 m/s$ (final velocity)

And therefore,

$v_2 = u_2 + a_2 t_2\\t_2=\frac{v_2-u_2}{a_2}=\frac{11.8-7.8}{1.83}=2.19 s$

So, the total time is

$t=t_1+t_2=4.26+2.19=6.45 s$

As light shines from air to another medium, i = 26.0 º. The light bends toward the normal and refracts at 32.0 º. What is the in

finlep [7]

Explanation:

It is given that,

Angle of incidence from air to another medium, i = 26°

The angle of reflection, r = 32°

We need to find the refractive index of the medium. The ratio of sine of angle of incidence to the sine of angle of reflection is called refractive index. It can be given by :

$n=\dfrac{\sin i}{\sin r}\\\\n=\dfrac{\sin (26)}{\sin (32)}\\\\n=0.82$

So, the index of refraction is 0.82. Hence, the correct option is C.
