Answer:
h=32.1 km
Explanation:
<em>solution:</em>
using newton law of gravitational attraction and newton second law:
r= distance between two masses
at sea level
a=g
.............................(1)
.........................(2)
by substituting (2) and (1) 
acceleration due to gravity at a distance r from the centre of the earth in terms of g (sea level)
so the weight of the object at a distance r from the centre of the earth (W=ma)
W=mg(Re^2/r^2)..........(3)
h the height above the surface of the earth: r=Re+h
putting the value of r in eq (3)
W=mg(Re/Re+h)^2
W=0.99 mg
solving for height h:
h=Re(1/√0.99)-(1))
h=32.1 km
Answer:
1) The ethical act Amy should display is to open the Email since it came in through her personal inbox. However, further action should not be taken since ordinarily opening the mail will not disclose or corrupt her system either locally of her system on the server and web space.
2) If such email came in, the first action i will take is to open the mail then take a pause to read through the instruction because most scam or malware comes with an array of further instructions.
After carefully reading through, i will call up Davey to confirm if he sent such mail which answer will obviously be a No and in the case where i am unable to get a call through to Davey, i will immediately delete the mail from my inbox to avoid the mistake of clicking any embedded link within the mail.

Answer:
The resulting pressure is 300 kilopascals.
Explanation:
Let consider that gas within the closed vessel behaves ideally. By the equation of state for ideal gases, we construct the following relationship for the isothermal relationship:
(1)
Where:
, 
- Initial and final pressure, measured in kilopascals.
, 
- Initial and final volume, measured in litres.
If we know that 
and 
, then the resulting pressure is:
The resulting pressure is 300 kilopascals.
