Basically, the purposes of digital multimeter are to measure two or more electrical values such as:
principally voltage (volts)
current (Ampere)
resistance (Ohms)
Answer:b) Point defects
Explanation: The point defect is the tiny defect that occurs in the lattice. It usually occurs when there is the atoms or ions missing in the lattice structure that creates a irregularity in the structure.The name point defect itself describes that the occurring defect is having a size of point thus is the smallest defect. Therefore option(b) is the correct option.
Answer:
Note that Air requires lesser work
Explanation:
Calculate for general work done
SInce Gas constant 'R' for: Neon = 0.4119KJ/kg.k , and Air = 0.287 kJ/kg·K
Calculate for work done of NEON
Calculate for work done of Air
See solution attached.
Answer:
Explanation:
given data
types of drinking straws
- square cross-sectional shape
- round shape
solution
we know that both perimeter of the cross section are equal
so we can say that
perimeter of square = perimeter of circle
4 × S = π × D
here S is length and D is diameter
S =
....................1
and
ratio of flow rate through the square and circle is here
