Answer:
Net forces which pushes the window is 30342.78 N.
Explanation:
Given:
Dimension of the office window.
Length of the window =
m
Width of the window =
m
Area of the window = 
Difference in air pressure = Inside pressure - Outside pressure
=
atm =
atm
Conversion of the pressure in its SI unit.
⇒
atm =
Pa
⇒
atm =
Pa
We have to find the net force.
We know,
⇒ Pressure = Force/Area
⇒ 
⇒ 
⇒ Plugging the values.
⇒
⇒
Newton (N)
So,
The net forces which pushes the window is 30342.78 N.
Answer:
helium-4 (90%) or tritium (7%).
Explanation:
hope it helped u buddy
It confirmed medeleeve's hypothesis (prediction) and showed the use of his table
Total resultant velocity=5.11-3.27=1.84m/s
- m_1=61.4kg
- m_2=109kg
- v_1=1.84m/s
- v_2=?
