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 
So height of mirror will be 1 m for complete image of person
Answer:
Pressure = force/area
= 650N/0.12m^2
= 5416.7 to 1 d.p
I got 650N by taking the gravitational field on earth to be 10N/kg.
Weight = mass x gravitational field
= 65 x 10N/kg
= 650
Answer is 5416.7 pascals (Pa)
Or
5308.3 Pa
if gravitational field was taken to be 9.8N/kg
Hope this helps!
