Answer: No
Explanation:
Length= 2cm= 20mm
Now meter stick can read to nearest millimeter.
It is given that length is to be measured with a precision of 1% of 20mm= 1/100 * 20= 0.2mm
Since the least count is 1mm of meter stick and precision required is less than that. So, meter stick cannot be used for this, travelling microscope can be used for this as it can read to 0.1mm.
Answer:All of the above
Explanation:
9.62 psi means 497.49 mm of Hg pressure
for (a)19.58 inches is equals to 497.49 mm of Hg
(b)atmospheric pressure is 14.69 psi
vaccum gauge is 9.62psi
absolute pressure is=14.69-9.62=5.07
(c)vaccum means air is sucked and there is negative pressure so it tells about below atmospheric pressure.
thus all are correct
Answer:
They communicate ideas very quickly.
Explanation:
Answer:
1. James will attack by generating a random private key XD and a corresponding public key YD.
2. Jane transmit YA to another person called Alex.
3. James intercept YA and transmit YD to jane.
4. Jane receive YD and calculate K1
At this point james and jane thinks they share a secret key but instead james has a secret key k1 to Jane and k2 to alex.
5. Alex transmit another key XA to alex for example.
6. James intercept and calculate k2 and vice versa.
