If absolute error is 1V and % error is 1.25% then Relative accuracy is_________. |
|
Answer» Explanation: PERCENTAGE error = absolute error / true VALUE 1.25/100 = 1 / true value true value = 100/1.25 = 10000/ 125 =2000/25 = 400/5 = 80V relative accuracy is between 79 and 81 |

A liquid weight 7.25n per litre .calculate specific weight, density and specific gravity |
Answer» Specific Weight = 7250 N/m³Density = 739 kg/m³Specific Gravity = 0.739Explanation: The weight of a liquid is 7.25 N per litre To find out: Specific Weight, Density and Specific Gravity Solution: We KNOW that specific weight is weight per UNIT volume of the liquid Thus, specific weight = 7.25 N/litre = 7.25 N/(10⁻³) m³ = 7250 N/m³ Density of the liquid = 7250/9.8 kg/m³ = 739 kg/m³ Specific Gravity of the liquid = density of the liquid/density of WATER = 739/1000 = 0.739 Hope this answer is helpful. |

Gauss law is always applicable but not always useful. Why? |
|
Answer» Answer: Gauss's law is always true (that is, numerically), but it's not always useful for calculating electric fields. It's only useful for calculating a charge DISTRIBUTION's electric field when certain symmetries (e.g. cylindrical, spherical, or planar) are present that allow the SURFACE integral to be DONE very SIMPLY. |

Q. why do we not use a plane mirror as a rear view mirror? |
|
Answer» Explanation: Plane mirror causes REGULAR reflection of light. When a parallel beam of light is incident on a plane mirror it is reflected back parallely. DUE to this PROPERTY a plane mirror is USED to see our image and not a rough surface. duster surface have MANY irregularities so in this surface, diffused reflection takes place. |
