It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.

Answer:

density = 6 g/cm^3

Explanation:

as we know that density is the ratio of mass and volume of the object

density = \frac{mass}{volume}

here we know that mass as well as volume both are always positive so the ratio of both can not be negative.

so we know that mass is measured in gram and volume is measured in cubic cm

so the density is measured in

density = \frac{gram}{cm^3}

so the correct answer must be positive and in terms of above units

so we have

density = 6 g/cm^3

vovikov84 [41]

Answer:

Secondary current is  8A

Explanation:

Data :

Primary supply = Vp = 240 V

Secondary supply = Vs = 60V

Primary current = Ip = 2A

Secondary current = Is = ?

Formula  :     Vp × Ip = Vs × Is

So for secondary current formula becomes

          Is = (Vp/Vs)×Ip =  (240/60) × 2

     Is = 4 × 2 = 8A

The lengthening of a transmitted signal's wavelength and/or a decrease in its frequency, which indicates that the object is movi
andreyandreev [35.5K]
Both the effects (l<span>engthening of the transmitted signal's wavelength and decrease in its frequency) indicates that the object is moving away from the observer, and this phenomenon is called Doppler effect.

In fact, when the object is moving away from the observer, the relative distance between two consecutive crests of the wave emitted by the object increases to the observer eyes, since he's moving away. This means that the wavelength appears larger, and since the frequency is inversely proportional to the wavelength, the frequency appears smaller.</span>
