Answer:
3801.13 N
Explanation:
Pressure exerted on a surface is equivalent to applied force divided by the cross sectional area. Then, the applied force will be equal to the product of the pressure exerted and the cross sectional area.
Where given:
Atmospheric pressure (P1) = 1.013*10^5 Pa
T1 = 20+273.15 = 293.15 K
P2 = ?
T2 = 120+273.15 = 393.15 K
Using the gas equation: P1/T1 = P2/T2
Therefore, P2 = P1*T2/T1 = 1.013*10^5 *393.15/293.15 = 13.6*10^4 Pa
The net pressure = P2 - P1 = 13.6*10^4 - 1.013*10^5 = 34.6 kPa
The net force 
Area = 0.11 m^2
Thus:
The net force 
= 3801.13 N
Explanation:
the acceleration will double because force is directly proportional to the acceleration
It is either the brain or the stomach.
Answer:
The diameter is 0.022m.
Explanation:
The magnetic field 
at the center of the coil is given by
(1). 
where 
is the magnetic constant, 
is the current, 
number of coils, and 
is the diameter of the coil.
Now, if we call 
the length of the wire, then it must be true that
<em>(this says </em><em> coil circumferences (</em>
<em>) fit into </em><em> )</em>
putting this into equation (1) we get:
solve for 
putting in the numerical values
we get:
