Answer:

d=0.4368 g/cm³

Explanation:

Density of an object is defined as the ratio of its total mass to the mass volume.

So that it is

d= m/V

d= (13.87g) / (31.75cm³)

d= 0.4368g/cm³

A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red

Alik [6]

Answer:

Speed of physicist car is 0.036c or 1.08 x 10⁷ m/s .

Explanation:

Doppler Effect is defined as the change in frequency or wavelength of the wave as the source or/and observer moving away or towards each other.

In this case, the Doppler effect equation in terms of wavelength is :

$\lambda_{s} = \lambda_{o}\sqrt{\frac{1-\frac{v}{c} }{1+\frac{v}{c} } }$ ......(1)

Here $\lambda_{s}$ is source wavelength, $\lambda_{o}$ is observed wavelength, v is speed of the observer and c is the speed of light.

Given :

Source wavelength, $\lambda_{s}$ = 660 nm = 660 x 10⁻⁹ m

Observed wavelength, $\lambda_{0}$ = 555 nm = 555 x 10⁻⁹ m

Substitute these values in the equation (1).

$555\times10^{-9} } = 660\times10^{-9} \sqrt{\frac{1-\frac{v}{c} }{1+\frac{v}{c} } }$

$\sqrt{\frac{1-\frac{v}{c} }{1+\frac{v}{c} } } = 0.84$

${\frac{1-\frac{v}{c} }{1+\frac{v}{c} } } = (0.84)^{2} = 0.7056$

$1-\frac{v}{c}=0.7056+0.7056\frac{v}{c}$

$\frac{v}{c}=\frac{0.2944}{8.056}$

$v = 0.036c=0.036\times3\times10^{8}$

v = 1.08 x 10⁷ m/s

A straight conductor carries a current of 755 A from east to west. It is 5.80 m above the ground. Part A Find the magnitude of t

Svetach [21]

Answer:

a. 2.6*10^{-5}T

b. north to south

Explanation:

In this case you have to take into account the expression for the magnetic field generated by a current

$B=\frac{\mu_0I}{2\pi r}$

where mu0 is the magnetic permeability of vacuum, I is the current and r is the distance to the conductor in which you want to measure the field.

A) By replacing we have

$B=\frac{(4\pi *10^{-7}\frac{T}{mA})(755A)}{2\pi (5.80m)}=2.6*10^{-5}T$

B) The direction is obtained by using the right hand rule. In this case, the current is from west to east. Then the direction is from north to south

Hope this helps!!

What is the minimum height of a planar mirror placed in a vertical plane 2m distant that will permit a person 2m tall to see the

Taya2010 [7]

Answer:

Height of mirror will be 1 m for complete image of person

Explanation:

We have given distance of person from plane mirror d = 2 m

And height of person = 2 m

We have to find the height of plane mirror which given full image of person

Height of mirror will be equal to half of height of person

So height of mirror $=\frac{height\ of\ person}{2}=\frac{2}{2}=1m$

So height of mirror will be 1 m for complete image of person
