I think it will go down like decrease minus or whatever you call it
Answer:
The plane will be located directly above the bomb because they both have the same horizontal speed.
A shock absorbent mattress is built such that the boxspring
of the bed absorbs pressure that is exerted to the bed. Hence, if you jump on
the mattress, you would not bounce up and down as much as a normal mattress
because the springs do not oscillate much. This is done to endure wear and
tear.
Answer:

Explanation:
Given;
The operational pressure of the cooker, 
area of the opening, 
- We know that the gauge pressure is measured with respect to the atmospheric pressure. As the atmospheric pressure acts on all the components of the system being observed so, we only need to counter the gauge pressure.
As the petcock sits on the opening of the cross-section so, it balances the built-in pressure due to its weight.
<u>Hence:</u>

where:
mass of the petcock
acceleration due to gravity


You can use the impulse momentum theorem and just subtract the two momenta.
P1 - P2 = (16-1.2)(11.5e4)=1702000Ns
If you first worked out the force and integrated it over time the result is the same
